[My!]

apologies bois, i guess i meant fair as in it's not leaking and definitely runs fine, but i do hear a little rattle which a shop attributed to my timing chain. it's in my car rn, but i have a few guys interested in the engine with the details I listed about the engine (compression numbers, leakdown, and timing chain rattle which may be the top guide but i havent pulled cover to see)

330mm or 350mm wheel?

Im in the market for a new nardi. My current one is a 360mm

my tomei is 310 and I love it.
330 is also good
350 imo is too large and I hate it in a 240.

Does the OEM s13 hatch power antenna have 2 height settings - mid height & full height?
Mine's currently going to mid height only but does not have a factory head unit.
TIA

[zombiewolf513]

it has two settings. up and down. try helping it along.

330 if you've got a bucket or plan on getting one.

Anyone have a good resource/crash course thread on learning the inner workings of an SR head? I've rebuilt like 10 KA's by now but they are really the only engine I have indepth experience with other than waterboxers. Cam on bucket seems way simpler than rocker arms, lifters, etc. I feel like a noob asking but I've never had my hands on one and want to change that.

either ditch the hydraulic lifters and go solids(tomei kit is legit)

Or go with dual guide shim setup.

WPC treat everything in the head.

If u wanna go high flow, high hp, ditch the det head and go vet

Motive garage on youtube has documented the conversion very well, mazworx aswell.

This is helpful advice, but doesnt do much when I barely know how the valvetrain operates in a dohc with rockers. So maby extra parts that Im not used to dealing with.

Its not hard, look at pic of the head.. cam lobe pushes on a Y Rocker arm.. rear of the arm is the piviot spot, hydraulic lifter. The feet of the rocker sit atop the valve stem. When the lob pressn on the rocker arm it applys pressure to the valves causing them to open.

[zombiewolf513]

maybe the FSM?

I really don't see what the lifter does though, at least without the head in front of me. the cam lobe appears to sit on top of the valve stem, with the rocker arm separating them (i.e, there is no fulcrum between the lobe and the valve retainer as I am used to in a pushrod engine)

It seems like the lifter is just there as something for the other side of the rocker arm to rest on, and keep it straight. In layman's terms with respect to the valve, the cam "pushes it down", the valve spring "pushes it back up", and the lifter just kinda chills and goes along for the ride on the other side, with no "fulcrum"? what movement does it enact?

[S14rebuild]

The lifter is there to act as a pivot spot..the rocker arm has to "rock" move. Also since its a hydraulic lifter it adjust/takes up free space/valve lash diffrences.

It is a fulcrum... not in the middle but at one end.

[TheRealSy90]

The lifter is the fulcrum.

roller rocker sr20de lifters are a drop in upgrade for the DET head. Hold up better to collapsing at high rpm.

Hey guys, are 55w HID ballasts safe in the zenki headlight housing? I've found people running 55w in s14 kouki projector headlights, but wondering about zenki housings, wondering if they would melt.

And yes, I do understand how the light output will be in non-projector lights. this is for an off road application

[hellion240sx]

Anyone have led headlights in kouki lamps? I need to order some today. Had some good reviews on beamtech bulbs.
I found on old thread on led lights that didnt help much.
Thanks

You got it. Think of it like a B series, but with stupid crap like shims thrown in, and a hydraulic "lifter" that's really a dampener, not a valve lifter at all.

It's like putting more and more bandaids over an infected wound, instead of removing them all and disinfecting it. If systemic staph sounds fun to you, get into those motors.

LEDs in non-LED projectors will scatter like a mother and blind oncoming traffic if you don't re-aim the everloving crap out of them. 2D output versus 3D, different beam propagation, etc. All to end up with worse ranged output than a decent halogen bulb.

Philips XtremeVision bulbs.

My own small question: What's the cheapest way to buy a KA20DE crank?

[Future240]

^^^^I didn't even know I wanted an answer to that but thanks for the info.

Aight Zilvia, help a mod out.

Later this year when my bonus comes I am getting a notchtop SR rebuilt (bought with a spun bearing) assuming the crank is good and only needs a polish this is my build list for the shop. The plans for the car are street machine, maaaaaybbbbeeee a track day at Road Atlanta or run through the dragon's tail. No drifting ever.

The theme of this build is reliability not top power. The oem build includes arp headstuds acl bearings and oem timing per the shop.

S14 SR with stock Turbo
CP Pistons <- stock compression or boost to 9:1?
Stock Rods <- again not going for more than 380hp at the tippy top, ok for stock or upgrade?
Whatever headgasket the shop recommends
Greddy oil pan


Stock head <-- considering tomei 264 cams here, want to retain VTC
555cc injectors<--decided to get these
z32 maf
stock turbo <--later on down the road would upgrade to GT2871r
Enthalpy tune for the NA ecu I have
do i need a fuel pressure regulator?
going with walbro 255ph fuel pump


Thoughts? questions?

I am pre-buying some parts so I want to get some feedback on the items I am not sure about.

I stress again this is not a "I need 400hp" sr build. This is a " I want to drive this car without worrying about it breaking" build.

[S14rebuild]

Seems like a solid way togo..id still just put rods in it. Ur already there..

[Thursday7]

Whats the 2020 consensus on lower-HP (<400whp) fuel pumps? Obviously the walbro 255 has been the standard for years, but they still have mixed reviews and I just leaned out my 3rd engine and honestly think it can't be anything else besides it failing under load at this point.

Looks like Tomei and Sard have 255lph option (Sard is 265), and as long as you order from Tomei Japan, I'd trust that both of those units are high quality.

Then there's the Deastchwerks DW250, and I'm sure a few other (AEM? Aeromotive? Idk) domestic brands with something decent.

I had 2 AEM pumps fail on me. First one was just over a year old. Replaced it with another AEM, and the car sat for over a year. Pump failed the next time I went to drive the car. Filter was clean, tank has no rust. 0/10 would not buy again.

I've been running the Aeromotive Stealth 340 in my cars with no issues. Just gotta make sure you buy through an authorized dealer or else you might end up with some knockoff junk (same goes for walbro).

[hellion240sx]

Hmmm. It says for GM applications and I found an e85. Searching some more sites.

the stealth is a nice pump, preferred it to the walbro. with either pump make sure to hard wire it directly from the battery to ensure it doesent shit the bed prematurely. Aeromotive actually puts the hard wiring in the install instructions (warranty)

What are my options for S14 SR20 Ignitor Chips? OEM is like 300$ plus the rights to my first born, and then theres ISR OE for $80. Any one have alternative options or experience running the ISR one?
