I also later switched to a set of 3.6 intake manifolds.

stock clutch and exhaust bolt up fine. no issues running a 5 speed.

Perfect. Why did you not use the 3.2 intake combined with the 3.4 throttle body?

I did for a while, but when you look at it, you realize that the 2.7 intake and 3.2 intake are the same. My car is track only, so I was ok giving up a bit of low end to potentially gain some top end power. Not a huge difference in power and the 3.6 intake swap is a bit of a fuss to do, so I'd just run the 3.2 intake

Makes sense. I see you are in NJ, but do you happen to know if the softronic tune is compatible with the smog test required here in California?
