But do we think it's really necessary to goto 3.3L cylinders and pistons as the seller advised to make this work well? If amount of boost is becoming a factor I've noticed that many bolt-on 3.2L kits run around 0.7 bar and last with the standard compression ratio and fuel system. Not to mention different wastegate springs, bleed valves, and smaller turbochargers are all important. I just want to make sure this system will be able to bolt up to my motor, I can deal boost control from there.
After some research I'm also realizing I probably won't have to touch the 915 internally, which is a big plus.
Turbocharging my 3.2 has been in my mind for quite some time, but when the prospect of owning a Supra twin turbo came along I jumped at the chance. On that note, I already purchased an entirely OEM turbo system from a late 70s turbo car. I could always fab that, but this system interested me.
