There is alot you could do but I think the below should be the minimum required to reach your goal.Now what my question is... What is it gonna take to get the Z to pull like a train all the way to redline? Without sacrificing mid range? Not too worried about down low. Other than cam Does a plenum fix this?
TPIACE? What is it about ur engine that makes it so good up top? I've got an exhaust T'ed up in the next week or so but i know that want to nothing exciting to top end. So what is that i can do?
I think once i achieve a nice steep gradient on a dyno map that does not peak of until the rev cut says so...I think think i will be very very content with the car.
Drop in K&N Panel Filter
Aftermarket Equal Distribution Intake Manifold (possibly 05 model)
Complete Exhaust System (headers, cats, mid, muffler etc)
Utec Tune with 7000rpm Rev Limit
This should avoid any losses allowing you to be equally competitive with the Porsche in the lower rpms but will give noticable gains everywhere else, all the way to your higher rev limit which will allow you to shift closer to the Porsche. You revs will also be higher after each shift making your car pull harder after each shift.
