I am about to turbo soon and am debating on which turbo to run. I have a built b18c1 and will be running AEM EMS. The most power i want to make willl be roughly 480whp and roughly around 300 everyday. I will be mostly racing on the streets and just kind of think the gt35 will be to big

 

If you need to make 480, get the 35r...

 

which wastegate spring can get you 300 and 480??

 

i doubt u can make 300 on a 35r without 2 wastegates. and why not suggest a 30r to make 480whp?

 

I will be using a TIal 44 wastegate. I mean im getting a good deal on a Gt35 w/ polished housing and ill get it if im going to use the power. If the gt3037 will get me that power and with a noticable spool difference ill get that.

 

Why would he need a 35R for 480 WHP? The 30R will support around 550 WHP and the 35R around 650. The 30R is a better choice, and will spool up faster.

 

agreed ^^

 

3076r deff for less than 500

 

I wouldn't even consider a 35R if those were my goals...

 

3071r - good to 480
3076r - good to 525

when i made the post i was going off memory

 

What size wastegate would you guys run on a 30R if it was being pushed to the 500whp mark?

 

38 or 44mm wg depending on your manifold
Go with a 3076-12.
dont waste your money on the over priced HKS 3037.
