Hey, I am no the best one to asked. Lol. Being working with turbo cars for a while and gains are by boost and system efficiencies; in some respect.

I think the gains for NA are so small compare to money being shell-out. I personally think gains are made by High compression pistons and cams, and heads worked over.

For general performance, I would say exhaust headers, a nice 2.5" exhaust systems and a nice CAI, keeping and MAF tube the same size.

You want a real mod??? Do all the above and water injection(WI) :) or just a nice exhaust system and WI.

With WI & Meth, you can retune and run more ign for more power. Having a safe operation maybe difficult when the water runs out though.

I think people needing power should get a 2.0/2.5GT. Great expansion there, unless you turbo your 3R with up to 6-8psi. That would be a nice kick :)

I think in the end for NA, a nice suspension setup is all that is needed.

Just a thought but friends of mine are fitting liquid LPG which is supposedly much higher octane and getting great results on XR6 Turbos. You still get $2000 back from the Government I believe. Have a read of this http://www.lpgli.com/features.html

your limited with the H6 best of buying a turbo model.

seriously, some serious tuning and pipes but dont expect huge numbers .

if you can afford a blower well then its big numbers..
