Spike’s 240Z limped its way to us after so many months of poor work from other shops. \u00a0At first look this Z didn’t have the original inline engine nor did it even have a 6 cylinder in it. \u00a0Spike had it converted with the “lightweight” SR20DET. \u00a0My good friend “Rawb” argues that a 4 cylinder should not inhabit the engine bay of a Z, I disagree in this particular case.<\/p>\n

Upon arrival we found many issues to work through. \u00a0For starters the wiring doing for the EFI harness was non-existent so we went to work getting this all squared away (thanks Juan!). \u00a0We replaced the old skool HKS injectors in favor of new Nismo 740s. \u00a0We ditched the Nissan ECU, installed and tuned the PS1000 Haltech. \u00a0In doing so we got rid of the MAF in favor of a MAP sensor especially since there was an HKS BOV on the Z, added boost control, and the Haltech I\\O Box. \u00a0We also had the exhuast changed out for a full 3″ single out and upgraded\\replaced the inlet and intercooler piping. \u00a0The air filter was moved out away from the engine bay and up front in the bumper area. \u00a0The SR retained the factory turbo.<\/p>\n

Part of inlet and outlet piping disassembled ready for upgrading. \u00a0We added a catch can and insulated\\wrapped the breather hose running near the exhaust manifold.<\/p>\n

The old HKS injector(s).<\/p>\n

A shot of some of the old crush bent intercooler piping that was also undersized.<\/p>\n

The Haltech ECU tucked away.<\/p>\n

Here’s the upgraded intercooler piping. \u00a0We had it made in lightweight aluminum along with the inlet piping.<\/p>\n

There was no way we could get a baseline pull on the Z when it came to us due to poor running, we tuned the Z first on low boost, the old intercooler and inlet piping, and old 2.5″ exhaust. \u00a0This netted us 219 whp at 9 psi and a drivable car (green run). \u00a0Once the upgrades to the intercooler, inlet piping, and exhaust were done we retuned for higher boost. \u00a0285 whp on 15 psi (stock turbo) and 91 octane. \u00a0The stock turbo is the biggest restriction on this engine now that the breather mods have been done. \u00a0You can see it boost creep at the higher RPMs, the wastegate flapper door can’t let enough exhaust out.<\/p>\n","protected":false},"excerpt":{"rendered":"
