i bought my 03 z new in o4 and ever year ive done stuff to it (its basically a garage queen, i have 15k miles on it). Ive got borla dual exhaust, test pipes, popcharger, plenum spacer. I was thinking about the osiris tune system this year......am i about done as far as reasonable mods for return on horsepower? How about a lighter flywheel? Nos? Forged internals and nos? I thought id go twin turbo one day but i just cant see putting that much money in and honestly, the thing is pretty peppy as is. I havent been here in years so cut me some slack on the searches, i tried.

 

OK I will.

 

Tune and maybe a new clutch / fw.

Taking off those stripes would help too.

 

Mainly this.

 

If you put a turbo or supercharger on it that peppy will be considered crawling and you'll never look back.

 

A tune is a good answer to get the most out of your mods.

 

^^ this. youll be happy for along time after doing this one mod. ( tune) as your parts have done nothing for you now in reality... a tune is the only way to actually get what youve ALREADY paid for.

I have the feeling youre that kind of guy.. a simple enthusiast.. this would be money well spent for that kind of deal.

 

Tune, and maybe a kit? :P I am seriously jealous how your Z has so little miles! What a BABY!

 

Drive it and have fun, but a tune will tie all your mods together.

 

thanks guys

actually the stripes turned out nice, the pic isnt that great but i get a lot of compliments, they are fatter than they appear in the pic

ill get the osiris on this summer and see what happens

 

I have basically the same mods + ISO Thermal gasket + Lightweight Crank pulley, and HR Y pipe. Now ready for tune. Heard a lot that lightweight flywheel will add that cement mixer rattle. Even stock dual mass pres plate make our cars loud enough. Only item I regret selling is the Motordyne test pipes but this is Ca.

 

Get that tune done!

 

Uprev tune for sure. consider a clutch/flywheel/LSD upgrade as well down the line.

 

+1 on an uprev tune. Once you bite the bullet you'll wish you did it years ago. If you think you'd be interested in the tuner version so you can tweak it yourself instead of relying on a shop all the time PM me, I've got one for sale for deals

 

Before anymore mods, do us all a favor and buy this:
