Redline S2K

Looking to pass or crest 600. I currently have the gtx3076r on the ptuning kit. From the research I've done. Doesn't seem my current turbo would be up to the task. I know comparing it's performance from other cars isn't apples to apples. Also looked into the gtx3576r but not many are running it. I don't want to have to step up to a gtx3582 if possible. I enjoy the quick spool of gtx3076r. Are there any turbos that'll reach my goal and still spool quick? Maybe something in the Forced Performance line up?

What fuel? What fuel pump? What size injectors? Single or dual exhaust? What dyno will you tune on?

600whp on a Ptuning kit you will need a GTX3582 and e85.

400 walbro pump, 1000cc injectors, single 3inch exhaust. Will be running c16 as I don't have e85 close and don't want to buy injectors and a different pump.

EFR 8374 should fit the bill, probably will have the fastest spool of any turbo at that power level

you will need to swap out the turbo to a gtx3576r. You will also need to run e85 and you will need bigger injectors. i recommend the id 1300cc or the fic hi z 1650cc injectors. i also recommend a fuel fuel sensor. OR you can just run race gas. 1000cc injectors will make 600whp no problem with race gas. Race gas is just expensive and not practical unless you just it only for racing and not on the street.

here is my stock f20c with a gtx3576r on the track forged manifold. 450whp on 91 octane and 617whp on e85. the red line was my old 2.4 f24 stroker. The stroker makes the same about of power but spools about 500rpm faster. I wold expect you ptuning manifold to spool the same or close as my 2.4 stroker since the running on your manifold or short. The ptunning manifold should spoool 200-400rpm faster than mt track forged sidwinder manifold.

efr turbos will not fit on the low/side mount ptuning manifold for 2 reasons. the dimensions of the turbo are to big to fit and the ptuning manifold use a 2.5 inch vband inlet. ERF turbos are only avaliable with t3 or t3 inlets.

EFR turbos can only be used with a top mount or sidewinder style manifold.

The fasting spooling turbo for a 600whp goal with a ptuning manifold would be a garrett gtx3576r with a .63 tial vband hotside.

Ah, I was wondering about that right after I hit post.

Unfortunately the EFR series won't fit with a ptuning kit. The gtx3576 is my top choice, followed by the gtx3582r. I have no problem running race gas as my car is driven maybe twice a week and not very far. Was thinking of doing the following.

GTX3576
Ported intake
Big throttle body
c16

Also looking into maybe a stroker and lower compression.

everything looks good. For that power level i would just stay with the stock motor. The stock motor is very strong. Dont fix something that is not broken. My stock f20c makes 617whp and has 120,000 miles on it and has been turboed since 80,000 miles.

I haven't used one, but Treadstone makes a Vband Hotside for the EFR Turbo.

It def wouldn't be bolt-in tho.
