Parts galore!

05/07/2016

I knew from before I even purchased the new STi that I’d be upgrading quite a bit. I did a lot of research and landed on the new EFR7163 turbo (the official turbo for all Indy Car racing) because I wanted a car that was ultra responsive, while still putting down some great power.

It’s documented on several other users’ cars that 500whp is definitely attainable, but the transient response and low-end spool are supposed to be out of this world! I regretted moving to a FMIC on my last build, and the headwork I had done had somewhat slowed down the low-end response. I’m keeping the heads stock this time around, and definitely sticking with a TMIC.

IAG, based out of Maryland, hooked me up with almost all of the parts (since most of these parts are their own design). TurboKits.com supplied the turbo, and a few other parts came from RallySportDirect!
