Hey guys ime going to being doing some more perf. mods within the next few weeks, i was thinking about the aluminum ds, headers, pulley(if you think its worth it). Let me know what you think would be the best mod. ime wanting it mostly to help my track time. By the way, 2005 z4, raced my buddies at the track last weekend and beat it twice. kinda kool.
Back on topic!
thanks guys!

 

Well, first off let us know what you car has right now or if its stock and if its auto/manual.

 

aluminum d/s, headers, pulley...you are thinking about getting just one of them, or more? and +1, we gotta know your current mods

 

I think all listed mods are worth it.

PS-Were you the guy that had a PH411 turbocharger awaiting install? If yes, what happened?

 

I have an auto, cai, tune, exhaust, 4.10's, tlok.
mustang joe, ime waiting abit before i get the ph, the moneys here but i need it for more important things at the moment, ime just doing some of the other things im going to need when i do, hopefully it will be soon when i can get it done!
And basketballord im wanting to do all of them just seprate, if i do the turbo will the pulley even be worth it?

 

I don't think the pulley will work with any FI, so go with aluminum driveshaft or shorty headers.

 

I always thought headers were a waste of money? Am i wrong?

 

They are worth it if you want a better sounding and flowing exhaust. They also net you a little power too. They will definitely be worth it for sam because he is getting a turbocharger in the future and could use the extra exhaust flow.
