Turbo's and Superchargers aside. For those of you with experience, which one mod actually made you feel a performance difference, if there is one.

If you had to pick just one performance mod, what would it be?

Crawford Plenum

viagra....

But seriously, just get a filter and save on gas mileage

F/I: nitrous
N/A: people have to understand that mods work together as a system, and the VQ35 just so happens to be on the mod-unfriendly side. If I had to pick just one it would be between headers (depends which ones) and test pipes/hi flow cats.

R-compound tires.

That's a tough one. But, if it were just one - Crawford Plenum. Reason, this fixes a design deficiency inherent in the intake. With the stock plenum, the rear cylinders get more air than the fronts. The Crawford equalizes this condition.

do you think crawford is better than Motordyne?

first of all, do you have an 05 6MT? Because if you do, neither will do much. Some people will tell you that either product made a huge difference, others will tell you they didn't feel any gains at all. So it's all subjective. If you want objective data, go to the Modifications forum and dig up some dyno charts of both.

I'd get (and did... what bias?) the ztube + pop charger. Since one mod (especially inexpensive ones) don't make a whole hella difference regarding WRHP, the z+p as least sounds like you added alot of power.

For more dinero what the hell, I'll say some high flow cats.

Gotta be exhaust. I loved my Borla.

i'm pretty sure rims & tires isn't performance, but it does give you a nice minimal gain and as well as looks!!

Id Say Stillen Sways Then Borla Then Tires. Ztube/k&n Didnt Make Any Diffirence To Me-performance Or Sound Wise....im Installing Md Spacer Tomorrow Along With Tokikos. Ill Let You Know!

performance difference would be all suspension stuff. IMO NA mods would be a waste of my money for minimal gains.
