The basic cookbook recipie of success however is:

JWT or Enthalpy ECU
GT2871r or GTX2867r (in .64 housing for both IMO is the better setup)
JWT S3 or S4 cams
OEM turbo manifold with Honing
Greddy (or freddy, sigh) Intake Manifold
Quality Intercooler (Read: Greddy RSPL)
Pump gas/20 psi.

Now engine wise we can forver debate what is best. I think we all can agree (know better) than trusting that setup on a stock engine. Sure will 1 or 2 guys never have an issue? Sure. I went a while until popping an injector gromet up and leaning it out. The safe bet though is to put a set of forged (CP) pistons (stock rods IMO are totally fine for sub 500whp) and a Quality (Apexi, Cosworth) headgasket and some ARP or Mazworx head studs.


It's a simple setup for sure, a little costly, but nothing more than blowing up stock junk twice anymore. WHen I set the car up, SR parts weren't the easiest to find, so you had to make it last.

My engine is still around, and I'd argue sees THE MOST road race time of anyone on Zilvia that can still drive their junk on the street(ok there may be 1 or maybe 2 that have more) and I've never had any issue. Quality parts will last.


The biggest issue IMO of the setup is everyone wants to skip a corner, or try something different...which is fine, but then people begin to forget that these setups can make awesome power...just not with an ISIS 2871r, or small cams, or with similar 'not the same' type builds. The setup I have works, and has worked for almost a decade...yet nothing has come out to really impress me enough to change the entire deal over. Sure VVL heads and that technology is aweseome, but I'm not spinning to 9500 rpm, and i only have a T2 turbo. If I was reallyy going to make a full out max setup I'd have a GTX30, and a wild VVL, but that's not streetable fun to me...

With Cody's recipe for success, I cleanly made 420whp on a .64 housing, on pump gas, and beat the hammered shit out of it fairly regularly. Save for my weird hesitation issue that I cannot diagnose.
