So I recently got tuned for my ef3 and full race prostock mani. I netted 406/331 I was honestly hoping for more but it is what it is. So ive been looking around and I think my goal is around 475 on pump 93 stock block for now, jet numbers.
I am between 2 choices; the gtx3576r stock location... or the full race 7670 efr kit.
I never plan to run e85 due to lack of availability in NJ but I do plan to build a short block down the line. I know with out being told that the efr kit has much more potential in it but since I never plan to run e85 I don't think I can ever really take full advantage of it anyways.


My question is... will the 3576r allow me to hit my goal or should I just skip it and go efr kit?

 

The 3576 would be easiest. You will be power limited because of the stock block. On pump gas you should easily hit 450+ with a good tune. I run one on my personal car. Great turbo. Hit me up if you want a deal on one. You're welcome to stop by the shop if you want to see mine. Otherwise the EFR setups are super nice if you want to bite the price bullet. E85 isn't as abundant in NJ but there are a few places I know where to get it.

 

hey IRP I actually live like 4 miles from you im in woodbridge. I didn't even know you guys were there until your recent dyno post of the 3582. That is what has me leaning towards the 3576r it seems to spool similar to my ef3 but obviously much more up top. Yes can you please pm me pricing info for the 3576

 

Shot you a pm.

 

Any other opinions out there? Looking at a lot of charts the 3576 and the 7670 seem to be very close in terms of power.

 

If you go with the 7670 you're going to need a whole turbo kit. The benefit of the ATP 3576 is simplicity of bolt on.

 

Did you retune your car on the 3576 yet?

 

7670 kit- I've got this kit and pretty much feels like a stock turbo. No lag and starts pulling around 4000 rpms. I am currently putting down 490 awhp and 378 lbs of torque on a stock block. Might be a little pricey but well worth it in my opinion. I have dyno sheets as well.

 

Car is running but I'm still waiting to get base tune done. Hopefully in the next few days. Then need to break the new motor in before putting some power down.

 

thanks for this post! i think the same, these turbos are not cheap but they are very good quality. and the spool
