To be honest, its a combination of things that turn me off from wanting to do the turbo renesis again. Cost, time, resources, frustration, etc
As a whole, I was pretty happy with the end result. The car had what the renesis was missing, which was a bottom end and STRONG mid range that pulled. The problem was it fell off at 7k, no matter what you do, that problem is in the hardware. I think with a different turbo and manifold setup, the renesis exhaust ports would easily support upwards of 10-13psi and make well over 300whp all day long reliably, but at what cost?
The biggest problem is the engine. I just dont see a configuration that will come online early enough and still maintain a high enough level of boost to make big numbers (500+) on the renesis. I hope someday I'm shown differently. I'd love to see a bolt on 500whp kit for the renesis...
Probably the biggest turn off is that I was/am a seven guy. You can get so much more for much less effort with an old style 13B.
I am still VERY happy with the NA 8s power though. Sure, my current 8 doesnt have the HP the last one did, but its still fun. I think with all the bolt ons and the soon to come out RB header - the NA renesis will make plenty of good power for a daily driver and weekend track day. After all, its still a 200+ hp NA 13B, thats good in any book.
My big HP goals will be achieved the old fashioned way - big port, big turbo, old car
