How much power are you trying to get out of the engine? What are your goals? If you are going for 300-350 rwhp, go with the GT3071. 350-450, a GT3076. For 450+ go with a GT35.

If you size the turbo right, lag will not be an issue. I reach full spool at a little over 5,000 RPM. Anything between 4,000 and 9,000 RPM and the turbo spools VERY VERY quickly

 

Cams are cool but they just aren't practical on this engine, did the FI BC cams make any power?

 

I want my car to put out 300-350 rwhp. Other then to get more power i want more throttle responce with little lag. Im looking into getting a pulley kit from ricks and a light weight flywheel.

 

They lost power as just about every aftermarket cam has...

 

That sounds just like a 3071R to me.

Sounds about right to me.

 

Thanks for all the advice

 

To my knowledge the only cams to make power in our cars where the Stock ones or Skunk 2 FI cams....A Friend of mine switch his 2.0 Exhaust cam out to a 2.2 Exhaust cam amd mad about 20RWHP over his stock 2.0 cam...His peak power only changed a little bit 5 maybe 10 RWHP....Also there are some people putting in NA cam with their FI setups...I havent seen any dynos or info on those yet though.

 

turbo lag with a modern properly sized turbo is a myth fro the past, dont worry
