I just recently chipped that exact piston 2 days ago. Doing a full build. I'm going with the ef4 as well. With a stage 2 gsc cams , ef4, using 93 Oct can 550whp possible? If so what do you think would be the max achievable whp with this set up? Thanks

 

Your in NY right? We ever met?

 

Get a used T3 kit. You'll thank me down the road. I got mine and couldnt be happier.

 

Cams will make this boogie

 

I second the T3 option. Although, I do think that I am going to pull the trigger on the 25G turbo that another company sells with a TD06SL turbine, I am confident that that will get me within sight of your goals, minus the cams.

 

Thanks for the info.

 

I want to give you advice but since you haven't purchase anything yet I rather just steer your towards a T3 kit.

I'm not the biggest fan of stock frames. I feel like people only really get them cause they work with the other bolt ons you already have so it seems cost effective at the time to just get one.

 

Makes perfect sense. Thanks
