So...I'm a proud Z owner of 4 months...and have been on this board daily, digesting as much knowledge as I can...I'm pretty happy with the car, so I'm not looking for anything major...but my plan for the car is listed below...if anyone can chime in and let me know if theres something I am missing or doing wrong, that'd be great (I'm not looking for loads of power...just a bit more UMPH):

MD 5/16 iso Spacer (Already purchased)
Greddy EVO2 (Already purchased)
Tein Basics (Already purchased)
Berk HFC metallic (about to buy)
now I'm not sure about headers...and UTEC...

I will probably install the exhaust this weekend...and the spacer the week after...suspension might go in a month from now...meh...I'm so bored in my hotel room...sorry if I'm wasting your time reading this...but I appreciate it

 

Strup headers....easiest to install....pretty good gains...fairly inexpensive. UTEC is probably worth it with all those boltons. JWT popcharger, Z-tube, 3" MAFS. if youre non-revup. just a K&N drop in instead of the JWT if youre a revup.

 

Personally, I wouldn't bother with the headers. According to other posts I've read they are a very minimal gain, if not a power loss on NA VQ motors. The UTEC would be a great upgrade.

I'd consider the MREV2, CAI, and obviously a tune to go with the UTEC. Cams make a huge improvement.

WARNING: ***** ALERT BELOW!!!
I'll sell you my Nismo Cams with 15k miles

 

haha thx guys...I have a 04.5...non-revup

 

If you have the money, go for the headers and add a utec.

If you are going to pass on the headers, there really is no reason for you to get tuned, unless of course you want too

 

skip the headers, get an 06 + airbox (popcharger is a waste no matter what year your car is) and drop in filter, 0 point in doing anything to the MAF at this point.

The UTEC and tune would be the single BIGGEST gain you'll likely see from the mods you listed. With the spacer, exhaust, cats and UTEC + Tune, expect about 260 whp or so on a Dynojet

 

Actually, probably more. I had 259 WHP without a tune, with no UTEC. I did have Cams too, but they are only about 10 peak HP, they just help even the power band out.

 

Headers won't do much unless you do headwork, you will only get minimal gains with them. If you still want to do headers as stated before strup is easy to install although crawfords in my opinion are a better choice. Utec for sure will give you a gain and the car will respond a lot better. So the choice is yours.
