I plan on doing intake, exhaust, headers, underdrive pulleys and ECU. What kind of hp gains would i be looking at?

 

There are plenty of dyno results based on various intake, exhaust and ECU reflash. However, no numbers for the underdrive pulleys.

 

Not wrthy enough to spend all the money to it I think. All that you described will cost you at least a good $3000 with installation of course(I might be wrong) Might as well wait for the super charger.... cost bout $3500 - $4000. But what do I know...

 

I still debating about it, i might have enough money left over to do the supercharger or turbo and everything else i just wanted to know what i could get out of all of that. how much hp woul di get from a supercharger

 

No official HP gain for the S/C but from what I hear (read in the forum) roughly about 50 - 70 HP? Again I might be wrong. For me reflash and intake would be enough for the car. It'll give you about 30 HP gain.
