Silvia 1jz Build

[Reece]

This is also a very pretty car

[jonny mac]

can't remember if i posted this earlier or not but the block is now at mac motorsport in dundee, marcin has the blocks machined out to match a 2jz gte and will have a full set of oil squirters, full oil gallery work done and the oil feed machined so they are identical to a gte block in every way
he's supplying all the parts for the build from real street performance in america for the bottom end, bar the oil squirters, pumps and seals which i already have

current 1jz setup is now sold, not removed from the car yet but the buyer is happy to wait as he stll has a little bit left to pay up
stripped the pistons off the GE rods, these are the strongest version of the rods toyota made for the 2jz and they are staying as marcin said they can handle up to 800hp ish which is fine for my application

thanks robyn at conceptua for the rapid delivery on the arp head studs


while on the phone, i'd also ordered a set of brian crower tianium valve retainers and stiff sprigns


got my spare gold e wings sprayed silver for the time being, couldn't find anyone who can mirror polish them so it'll do for now


went through with the decision to run a bmw diesel gearbox, this is the 5 speed 330d gearbox kit from clarke motorsport in aberdeen, designed by marcin i believe
twin plate clutch and comes with all the adapters needed to run on the back of the 1/2jz block
rated to 850bhp from memory more than enough
will drive ace too since it's a twin plate
was not cheap however this setup will be awesome when done

then came the bmw 330d gearbox, got it from a breakers yard but unfortunately turned up with a dead propshaft doughnut, a un-usable front prop section and a broken gear selector.....typical


gear selctor is away being repaired now by tig welder paul

the dead prop bushing is fit for the bin....bought a new bilstien one for £100


bought another bmw propshaft for the 330d box, new prop doughnut on that now and it's ready to go onto the gearbox and be chopped to size to meet the rear half of the s14

been ordering some more parts from japan, this time i've ordered sard 800cc injectors and have them as 'drop in' fitmenet for the factory fuel rail
however, been told by the supplier that sard have them on back order until end of april, so i'll have to wait

i did buy a top feed rail but in the end decided side feed drop in ijectors will do for now unless the car is having issues during mapping/making power
marcin sent me this picture of the bottom end parts that have arrived for my/other 2jz bottom ends he's building just now (one being for my mate cam's jzx100)

getting excited now!

got this for the front of the engine once it's complete

also looking at doing a dual feed on the stock rail to keep fueling equal and not risk starving the injectors at the return end of the rail
so the theory is, drill into the center of the rail and have a return made
going to use this extended an6 fitting so it'll be easily accessable even when the intake manifold top half is on

just taken delivery of teflon braided an6 hose, 3m length and also a few an6 fittings/m14x1.5 conversion fittings as i'm going to redo the full power steering system pipework when the new engine goes in

[jonny mac]

Marcin has sent me some pics of the block progress, it's now ready for collection so i'm heading down in a few days to collect it
my and my mate cam's blocks

block machined to have gte oil squirters and the gte oil feed on the side for the turbo

my new toyota squirters and bolts in

my crank back in with the oem bolts and caps with new ACL bearings

forged 8:5:1 ratio cp pistons onto the stock strongest 2jz rods from the non vvt n/a block
(compression should be around 9 with the 1j head)
reason for not going forged rods is that marcin's advice was stock rods are good for 800hp+ which i won't be near

pistons in




my precision turbo has arrived at marcin's, however the turbo housing on the back was the wrong size so it's being exchanged
went for the gen2 dual ball bearing 5858 model with a .6 t3 housing on the rear, 4" inlet and 2.5" air output




my 6boost manifold has turned up thanks to wayne at autoextreme, i bought this on the group buy at the start of the year
t3 twin scroll, dual 40mm wastegate outputs and the 32nb pipe diameter

the collector is well done

along with that came two new turbosmart 40mm external wastegates



so right now i'm waiting on my head from bret sims motorsport, my sard injectos from nengun (which are on back order)
and marcin is supplying the ecu+sensors+universal loom to be made up from emu ecumasters
one of these: http://www.ecumaster.co.uk/products/...anagement-unit

[jonny mac]

collected the block at the start of the week

oil feed holes machined just the same as the 2jz gte



cylinders look in great condition after a hone




also picked up the ecu at the same time





paid extra for the bluetooth sensor to run live data on your mobile phone or tablet,
2m universal loom
the nox sensor,
new coil pack clips for new style coils,
oil pressure sensor
i'm now waiting on marcin to get delivery of the air intake temp sensor for the throttle body side i/c pipe and oil temp sensor which will go into the oil pan/sump


going on marcin's recomendations on coil pack upgrade, i've bought 6x bosch fiat turbo coil packs, part no 0221 504 024, they have built in igniters so i don't need to run the box anymore


ordered a new AEM/K&N filter which is HUGE!

and for now lastly the fuel system parts are starting to roll in, AN8 ultraflow torques 90 degree fittings, a few -8an weld on fittings and some -8am ptfe teflon fuel pipe

[jonny mac]

went and collected my clutch from clark motorsport, actually comes with the flywheel starter ring gear now as one piece
so i have an auto starter gear for sale for £50 for anyone looking for one with a jz haha,
i bought one last month on the knowledge that i needed it for the kit but because i've ended up with the revised version of this kit i don't need it anymore

also got the bel housing adapter plate with correct bolt kit

bought an aeromotive fpr, just need to get the fittings and the gauge for it next

along with a new tial 50mm bov from the states

also i've now got some pics of the precision 5858 gen 2 dual ball bearing turbo, t3 housing .63, will be mega fast spooling!



loads of other parts have started turning up, like the 90* 2.5" alloy bend for the turbo

stripped the brand new oil pump

they are bad for having poor flow castings and rough bends, this helps flow, i've opened it up a fair bit too just like the performance pumps you can buy in america

this is only a 'during' pic to show some difference, this was tidied up and finished after

likewise, you can see all the rough sharp edges and even lumps in the casting on the oil path ways

every single screw/bolt was tipex'd and marked in its original postion, even numbered them all so they went back on exactly where they were
also marked the gears to make sure they were bang on where they should have been before i stripped
loaded it up with engine assembly lube and lubed up the gears teeth too
the green stuff:


began gasket matching the inlet manifold


also done a new aux belt tensioner bearing for the new engine

changed over to an s15 spec s clutch master cylinder i had spare at my house as the old one was leaking, however i'll be taking it back off soon to paint the bay when the engines out so all the brake fluid burnt paint will be cleaned up and sorted

bought a pair of straight rack spacers from opjp, these are the kaizen drift brand if i remember correctly, this will elimnate the need for offset rack spacers when i fit my modified cross member

after being ripped off 150 quid import duty, my sard 800cc injectors showed up

air intake temp sensor for new ecu

had the rear of the crank gear teeth welded up to prevent them breaking off,
this is a common fault of the jz's and i want to eliminate any risk of problems with the new engine

parts shop max arb shorter mod brackets turned up,
will see if i can make some sort of drop link out of what i have to use these
this will regain me that wheel clearance on full lock like i had when i ran no arb, it shortens the arb's length and relocates the D bush brackets


have my modified cross member off to the powdercoaters, the rack mount has been moved forward 20mm and all the welds on the frame have been 'beefed' up by spice weasel on sxoc




--------------------------------------------------------------------------------


car in banzai uk magazine next month!


replaced the water pump and timing belt on the engine, it's only fair to do this for the new buyer of the engine as it had a small leak/pink coolant stain around the gasket, it means i can carry on using the car as need be without worrying too





engine head came back from bret sims motorsport, it's beautiful! it has had a huge port and polish job, all chambers balanced, 264 bc cams shimmed in correctly, multi angle valve seat job, new oem stem seals, all ports gasket matched and exhaust side opened up







it wasn't cheap and i cannot argue with the price as it was a few days worth of work but i believe it's all worth it as the head is where you get alot of power from,
It's a shame i didn't just go for a vvti head but heh that's something i can do with another car one day as i've got another 2jz ge vvti engine sat in storage now


i got my subframe back from the powdercoaters nice and black

the car is now in banzai magazine in the june month's issue, please purchase a copy to support an awesome magazine!






now, this is something i'm NOT going into online as it's not for forum's and such like,
I do not want to be seen or made out as someone causing trouble or slagging people off,
i wasn't happy with some marks on the block when i got it back and the previous builder had a disagreement with me and voided my warranty on my block,
he did offer to rebuild my other 2jz ge block so i could reuse the 86mm pistons he'd supplied but that's not what i wanted,
i was keeping that block for something else (hopefully a 3.4 stroker engine for another car in the future)
not going to sit online and make nasty remarks about people etc,
i have my block getting rebuilt and having oversized pistons put in by another place now as oversizing was the only way to have a correctly remove the scoring off the cylinder sidewalls,

I'd lost my warranty on the engine as I'd removed two conrod cap bolts and pushed a piston out to see if a cylidner could be rehoned to remove some markings, during that i discovered other things so i didn't feel too pleased about using the block

things haven't went good for me lately and i've had to sell the turbo to pay some money back into rebuilding the block again
if anyone would like to buy a set of 86mm 8:5:1 cp forged 1jz 2jz pistons please let me know, i'm asking £650 for them,
they are brand new and only in an engine that has been turned over by hand a few times, they come with wrist pins and piston rings etc



i've managed to get back £100 for my arp studs and GE n/a conrods so that just leaves anything i can get back for the pistons and i'll have to write off the rest as a loss,


so now the block is having a .5mm oversize cylinder job done by an engine shop that usually does sr's and rb's, it will have wiseco pistons and eagle forged rods, an expensive and annoying loss however i do not rip into people online and i am not to be seen bad mouthing anyone here
i want to make it clear i'm not slating the previous builder, i've already been accused of talking about him online weeks after we spoke which was someone else on another forum but somehow it came back to me, i don't like being involved in politics,
all i want is to get my engine finished properly and drive my damn car now!

so hopefully the next update will be pics of the freshly fully forged block sat in my living room having the mental head put on top and i can begin the exciting task of bolting on all the new bits and have a fast spooling 1.5jz soon!

[jonny mac]

Great Progress, Pistons sold!
engine block's nearly finished too and on it's way home to me next week


so, to start off, paid over the odds for a rad cap because it's genuine koyo...to be fair i thought my japspeed one was leaking which it turns out it was

bought another pair of black recaro dc2 integra seats again, seen them appear on a local page on facebook and made an offer on them
did end up putting the drive side in, just don't have pics

sunstrip came off and i've left on the finalboss part for now

Got married, used the Silvia as the wedding car

engine pics

ZRP Forged H Beam Rods

Wossner 86.5mm 8:5:1 Ratio Comp Pistons


Crank back from balancing against all new parts inc my clutch and flywheel assembly

block after having 3 days in the acid/descale tanks


oversized block work done, now decking the surface (surface was very uneven he said)


Look at the cylinder finish!


block painted

rings gapped

crank in

line up

my new toyota oil pump on with new o rings and it was ported out inside for flow restriction issues that can come with stock pumps

now i'm just waiting for the core plugs to arrive with him on monday then the engine's coming my way

as for the next big, turbo choice, i think i'll be going GTX3582R with the T3 Twin scroll exh housing as garret seem to be the only ones that offer twin scroll
borg warner and precision both don't list it in the turbo model's i like, so not to worry, a gtx will be fun

[soundboy]

damn, very good work. Im not to familar with the jz engines but wont a stock 2jz be a good option rather than doing all that work building up a engine?

[supersayianjim]

Updates???

after realising how much I'd spent on this build...hell yeah I should have just bought a 2j gte vvti

[jonny mac]

bought a gtx3582r
4" anti surge intake
2.5" out
.83 t3 divided exhaust housing
3" vband exit

it came from universal turbo's
formally known as CR turbos,





had to take the cams, shims and buckets out the head (kept in order) as the head needs skimmed now a little more
this is to let the compression come back to 8:5:1 as the oversized bore has increased the total cc in the cylinders
the head is now in a machine shop in a que of jobs to be done

block arrived home, i'm super happy with it
you can also see written on the piston is 20cc, the stock pistons are 9cc! hence the compression change so head work is needed as i'm not reducing the gasket thickness as the stock 1.2mm 1jz head gasket works really well


got the cam covers powdercoated electric blue with metalic flakes these are insane in the sun!

also have started tidying up little bits in prep for assembling the engine






literarly waiting on the head to have some more taken off then it'll be build/checking time as i need to make sure i have enough piston to valve clearance etc

oh also invested in a Link g4 engine management package





----------------------------

link arrived, with a 2jz loom which i'll need to modify to fit the s14 harness, vw coil packs, map sensor, fuel perssure sensor too


pulling an engine out in a 7ft wide garage sucks....




i then took the engine over to my work and changed a few things on it,

[jonny mac]

got it ready for the new owner's car. rear sump back on etc
spent friday evening pulling the old 1j/twin setup/w58 out of the soarer

swapped the looms over, starter, p/s pump, injector resistor pack was added into the loom and a few other bits. then dumped it into the soarer on friday night around midnight
then over the rest of the weekend messed around getting the car finished along with paul making exh pipes, intercooler pipes, gearbox mount etc


big thanks to mark for saving my bacon with the alarm, it freaked out and wouldn't send power to the starter relay

so, back to business
made a start at getting the engine together, put the dowel pins and studs into the block for the sump (not in the pic)

new o rings and so on for the sump where required


arp head studs and oem toyota head gasket on, dowel's put into the head too



head on, all shims and buckets back in head in the correct order


engine mounts/ bc cam's in with engine assembly lube



water pump

crank sensor



2x new camshaft sensors in

cam gears


2xnew toyota oem cam seals in too


timing belt



82*c toyota oem thermostat, seals and lower water pipe


how i've left it for now, waiting to get another free evening to finish it, bought a dti gauge for dialing in the cams, need to get a length of threaded bar the same pitch as crank to setup timing wheel

also not putting on the new blue cam covers until the engines fully finished so i don't risk marking them

[jonny mac]

things have been a little slow with this, i've bought a supra so have been busy working on that in my spare time, it's now off to the bodyshop for a full respray so i've now got some available time to push this thing forward

6 boost going on, had to chop down a few studs underneath the same as the last time

new o ring and refreshed oil filter housing on, however i'll be using a smaller 2jz ge one for space as i need to run two sandwich plates for stuff now

gtx3582r t3 twin scroll turbo goes on



turbo smart wastegates ready to have v bands welded on

vibratechnics 'drift' mounts going on

degreed the cams in as per brian crower spec sheet


new intake manifold arrived, 90mm throttle body, top feed fuel rail conversion, all o ring seals and looks pretty
i'll be able to start supplying these on demand for around £620 delivered within the uk too which is cool




also dumped the engine in the bay for now as i needed the space in the corner for something else, i'll have it back out to put the gearbox on properly as i couldn't get it lined up with the twin disc clutch
more pics later

grade 7 copper bkr7e plugs in for initial start/run in
will change to iridium grade 8's during mapping

[jonny mac]

got the car transported over to my work

got this back out the engine bay

so there was a bit of a problem with the adapter plate i had with my pink clutch, it would not line up with the box when on the engine, holes were a few mm off all over
thankfully the guys that sold it refunded me the full amount due to the time restricitons i had as i couldn't wait for them to order another batch of newer/remodified plates etc
shame really as i liked the clutch, it looked like a good piece of kit
i got straight onto abc and ordered one of their new style kits with the redesigned adapters, within a few days the new kit had arrived

went with the tilton twin disc setup
while that was in the post i swapped over the front subframes


rack relocated so no more offset spacers
had paul make up a new oil drain since the last one stayed with the holset setup, made a new flange too as the supplied one from universal turbos wasn't up to much

will heat wrap the silicone hose

cross member in, I need a new set of rack pipes, ignore them, they got caught when i put the old 1j/r154 setup into the shell outside in the driveway, the r154 had extra material at the base of the bel housing which tugged on one of the pipes

clutch on







came with a good instruction set explaining that you need to take material off the release bearing shaft on the gearbox

new gearbox prop bush

release bearing installed on the correct tabs following the guides


engine was in and out a few times sizing up things like wastegate positions, downpipe modification for new turbo, gearbox mount etc

had to shave the box as it has a big dowel pin for bmw starter motor and a few various high points that aren't needed, the box is seriously tight in the tunnel, a small massage with a hammer soon fixed that

used my old r154 mount but extended the tabs to reach the bmw box mounts, also used pucks as stiff bushes between, i'll repalce with proper poly the same size



starting to look cool, can't wait to hear both screamer pipes on full throttle on the rolling road for the first time

[jonny mac]

intake going on

throttle body is also on now, using oem toyota 1jz tps sensor which is cool


thread taped the vacuum fittings

also had to cut/flatten/modify the oem water pipe going around the engine for it to clear the abc kit

one thing that has always pissed me off about the car is the hammered arches, i had to smack them up a few years ago to clear the wheels after the geomasters went on and gave more lock
have now got half tubs done, battery tray removed and old intercooler holes cut out and replaced with new sheet metal

the old fuse box loom holes/air con holes/oem intercooler/airbox pipework holes are also gone and filled

made a start at painting, haven't got any proper finished pictures yet

needs cut back and polished but it's good enough for now

threw on a water pump pulley and a non aircon belt, going to run it first time without the fan on so i'll be able to hear any noises etc

new water gasket on the pipe going around the block and then it was time for final fit (hopefully for the last time)


it's in

made a start at a propshaft myself so i have it the right length before sending away to be professionally made by a propshaft shop hopefully with addition of a spline in the middle to allow for movement

[jonny mac]

roughly mocked up the prop to get the correct length, used a bit of boost pipe to hold it true at the correct length then tack welded


that was then sent away to bailey morris, used them last time for my prop and the were good

after speaking with paul beechey he'd said to use maxima rods since the rack's moved forward now and the offset spacers are gone
had the ends machined down 3mm to allow more travel


new rack boots on and recentered the rack after realising it's off (thanks to paul and clive for some advice there!)

made a start at a few coolant pipes on the engine

oem sensor and spa designs coolant sensors in the water neck, along with an6 outlet for turbo

got a an6 fitting for the rack

made a teflon line an6 high pressure pwoer steering hose

and a fitting on the pump high pressure side / resovior hose done also

need to shorten the shifter

bought some shockproof gearbox oil and millers engine run in oil from opie oils

got that in the box after draining out the old stuff (actually looked clean!)

new set of propshaft bolts from bmw

been having some bother getting the clutch to clear, cylidner doesn't feel like it's doing enough, abc recommended a 3/4 cylidner so i've bought an adapter plate to allow me to use a wilwood cylidner



wilwood cylinder on order and should be here next week

oil level sensor block off plate from a jzx90 from toyota

prop's done, brillaint job by the guys at bailey morris, has a splined slider added in too


made all the an6 water lines to/from the turbo now, it has feeds from the engine,
turbo smart wastegates on but without screamer pipes as these are going to be a bit tricky to make, alot of bends needed just like the downpipe, due to shortage of spage


made headlight brackets again this time from the radiator support tube,
i've flipped the incercooler core upside down and now i'm waiting for paul to come in and do some alloy welding to make up pipes to fit the throttle body etc

[Makstraw]

Damn this is hot.

[RB25GUY]

FUCKIN ELLL these build threads are on point as of late!!!!

[jonny mac]

had the gearbox on and off a few times as i couldn't get a good clutch pedal, the clutch wouldn't let go

result was i hadn't had the clutch cover correctly aligned on flywheel, thanks to fraser stark for spotting that
i don't know how i managed it tbh, it was maybe when i used the gearbox to line up the clutch discs, when pulling box back off it maybe knocked the cover down a mm or so which threw it off
abc were great too, really helpful and very willing to chat at almost any hour in the day for help and advice


got to the bottom of it eventually, cut a hole in the box to see if all working, i need to shorten my pedal now as it's releasing too early but it's all working as should
gap closed as it should be



so at this moment in time, i'm doing a final mechanical fit this week, every part is being bolted on for the last time hopefully, i'll have alot of wiring to do
but mechanically it just needs reassembled since everything is made now

exciting times!
seriously can't wait for this machine to get on the rolling road and find out what the story is! after all the bull shit and hard work it should be great fun

[hvp014]

wow amazing update! Can't wait for the start up vid!!

[EnvisionMore]

Interested in how those coils work for you and how you mount them. Great work!

[jonny mac]

the coils are tight on the plugs so they keep themselves mounted with no need for any brackets or bracing, only issue I can see I'd have so far is the wiring clips, not a lot of room left for that




had my spare 3.6 diff welded


also got an order through from torques uk
it's the twin bosch 044 fuel pump with bosch filter setup




1/8th npt boss welded onto the cooler pipe for intake air temp sensor just before throttle body

had some braces made up to try prevent boost pipes jumping off at high pressure


painted the diff, new oil in and a pair of painted 6 bolt shafts + abs rear prop section

got the powdercoated cam covers on

mounted swirl pot and new fuel pump setup, i've added a 10mm thick rubber square under the pumps where it's bolted to the car's body so they won't have to deal with chassis vibrations and it'll dampen the noise a bit

kept the fuel parts mounted up there because i wanted tyre space in the boot, also if i'd put these in the corner of the boot if i ever had a rear impact it would take out the pumps and surge tank and probably cause a fire with fuel everywhere
all lines i'm making in and around the pot/pumps are motorsport rated teflon lined pipes
