ha, i would like to go 260's... but i i dont feel like upgrading my entire valve train to be safe. im super conservative anyway, so i dont rev my shit to the max except on rare occassions anyway. found a another set of the pon cams for mad cheap anyway maybe. like half price son! we will see. if these fall through ill start looking for 260's i guess

[2fast4y0u]

if im not mistaking...and i could be
hks offers a 264 step 1 that u dont need a valve train upgrade for... maybe rocker arm stoppers, but those are cheap now. ISIS makes a set for $49.99

I was just going to suggest them. Chris ordered his through them for like 1100 with out a waste gate. How long untill your set up is in the car?

Oh and why not just run the internal waste gate with an HKS actuator?

Also its not really the duration that bothers the valve train its the lift. Tomei 260's (11.2mm) have a smaller lift vs the 254 (11.5mm) so you could run those easy. Also HKS Step ones (256/264) run a mild lift as well so stock valve train will be fine as long as you keep it at the stock rev limit.

[+Waldo+]

thanks for the info dan, and yea im not trying to increase my rev limit. i was planning to have the set-up in over the christmas holidays, but if i get everything soon enough maybe over thanksgiving break.

ill keep an eye out for those other two variations. BC are the only cams that need the adjustable Cam gears correct?

[longfellow]

I'd ask chris about the BC's. I've never looked into them as a viable option. The only thing I'd really buy from them is there valve springs and retainers.

I'm sure someone in this thread has usefull info on the cams though.

[slider2828]

BC Cams have been known to need degreeing for tuning.... So unless you or someone knows how to do that, don't use BC cams. Upgrading valve train I think is a must with bigger lift CAMs IMHO... Its not that expensive for parts and any machine shop who works on heads can do it.... Pon cams, are supposedly no need to upgrade springs, but Pro Cams and Steps 2's for sure....

I think BC's are the only ones...

[longfellow]

Eric, if you ever want to build that spare head of your's let me know. I have all the tools to do it at my place. Plus I have a spare S14 SR head to use for parts.

[Moon Ill]

Hey guys I have this one.

Any idea what kinda of actuator I need for it and where I can get it from?

[longfellow]

I thought HKS made one for it? The one you linked to already has a decent one on there.

[+Waldo+]

ill sell you the actuator once i get my turbo becuase im running external.

i guess i might as well go ahead and upgrade my springs and retainers. I dont know if i can use my spare head or not, cam caps are out of order and canals are groved pretty decently...

[longfellow]

Caps should be labled, but if the journals are trashed then I wouldnt use it. S13 heads are only 100-200$ or so on TR. I think it might be worth looking into.

The one for the RS style compressor housing, but not for this one. (I actually have one :-P) ...2 rather (T25 and T28 HKS units)

The actuator on it is one that was modified by the previous owner. I'm confident it might work, but I want something produced to work.

I agree. Power was great and response was awesome!

I had Gt2535 turbo set up on my redtop s13 and made 287whp & 283 torque; pretty much maxed out the turbo at 1.2-1.3 bars

-550cc injector
-hks 256 cams
-n62
-sard fpr
-skyline fuel pump
-greddy ras
-stock bottom end & head gasket
-tune with a apexi neo at Smoothlinez (9828 Alpaca st., South El Monte, Ca)

Go without cams, then get quality valvetrain stuff later, or do it right the first time, some ferreras and JWT cams

Did it not come with one?

the stock acuator should be sufficiant enough.

My W/G boosts up to 21+

[+Waldo+]

how are you going to come on here and in 3 post find me tommy haha. im going with a better valve train now probably.

[S13 curtis]

Im going with Tomei 270's im ordering them this week. then in a couple weeks i should be ready to put the 2871 back on. im hopeing for a better result with this new set up.

[2fast4y0u]

arent we still waiting for obeewon to tell us why his setup didnt make the power he wanted?????

where is he?

It came with one modified to work.

My issue is that the rod pushes on the arm at an angle rather than strait.

[+Waldo+]

waldo just got excited


still looking for injectors, cams, and gotta get my mani ceremaic coated and stuff.

[jspaeth]

^Holy Crap that looks nice!!!!!!


Just bought FC Datalogit today.....anyone having any fun with that? Ray?

[+Waldo+]

beleive it or not that is a megan tubular mani, custom set-up to run the external WG with extra supports added

[HPballer76]

have any pics of where you added extra supports? im wanting to brace mine a little bit better before i put it on.

[+Waldo+]

i didnt add them myself lol. picked it up like this

[midnight_rex]

what about the GT2876R turbo? ive been reading up on everything about the GT2871r but what about the 76r? a lot of the people in this thread want to achieve 400whp with so many mods towards the 71r and only achieve between 300-380whp. i want to achieve 400whp DD on a built redtop. im wondering if i can use the 76r and make 400 easier?

[S13 curtis]

^ yes you can ... the 2876r moves more air. it jus spools like 200rpm later than the 2871.
2876r is good to 420+WHP

[+Waldo+]

ok, offically have everything ordered. just gotta wait for it all to get here
2871r 56trim
megan tubular mani with tail external WG
Tomei 740cc
Tomei pro cams 260ex/in
BC spring and retianers
Enthalpy rom tune

lets hope for good numbers, and a more importantly a fun ride !

[usdm180sx]

Sounds like fun =) Hope you can get good customer service from Enthalpy in case the tune is off.

[+Waldo+]

i have two pretty close friends that work there so i should be fine. Im buying the ECU from a friend whom has it already tuned for
-z32 maf *which i have
-tomei 740's *which i have
-93 oct *which i run
-30r...

it should be fine, just a little fine tuning

[slider2828]

How much did it cost you to do that on a MR manifold? That looks badass....
