With a 207 I'd keep the .82 since it has higher RPM rev limit. I'd get a .102 actually if you can even find one. They're rare this day in age.

Hmm 2 conflicting answers lol. I bought the 63 if it's too small ill get the 82. I can't see the 82 spooling any earlier then 5.5k. The gtx35 is basically a gt40r.
Wish I had a dyno to put the car on. |

.63 seems to work just fine for that guy. Later on he wanted to downsize his turbo to the 3076 lol. https://forums.nasioc.com/forums/sho....php?t=2920024 |

I'll try the 63 first I want it to pack a punch in the mid range and hopefully pin me to the seat till redline. I found oil leaking out of the bottom of my driver side head gasket so looks like I'm gonna pull the motor this weekend and re do the head gasket.

Don't get stuck on the smallest A/R Quote:
Modern turbo and engine configs perform quite well with large A/Rs |

.63 is too small , egt and backpressure will be through the roof , huge imbalance across hot and cold sides
a gt35x is just like a gt35x , it's not like a 37r or 40r as they have larger turbine wheels |

So even on a 2 liter .63 is too small?
I know it isn't even the same motor but my friend ran a .63 on his 35r on an inline 6 2.5l, which I would think would have way more backpressure, but it pulled like a freight train. I'm not disagreeing with you guys just worried about lagging in between shifts. I'll ask my tuner and see what he says but I'll also take your guys advice and try the .82 first. Might even try tuning both and see the difference. Last edited by Mauled; 07-07-2023 at 11:38 AM. |

I think a .63 is fine for a 2.0 on pump gas. If you were running E85 or planning to max the turbo out then yeah .82 for sure. You are complaining about the 3076 with the .82 being laggy, the 3582 with a .82 will be worse.

It's not laggy if I shift at redline. Also running meth, not that it helps with spool. Seen a guy on here with a gt35r .63 making 468whp. I think the .63 gtx could hit 500. Like you said I'm not maxing the turbo out, 26psi so I don't think the .82 will make a big difference unless I'm running high boost.

Even with a small displacement motor, the high efficiency turbos these days don't need tiny A/Rs to respond well and be efficient. Don't take what your buddies inline 6 did and apply it to your setup. I'd stay on the .82 even on your 2.0, maybe even move over to a 1.XX to make the power and truly more linear. |

You have both housings and they're easy enough to swap out since you have a rotated setup. So just start with one, and if you don't like it/it doesn't meet your goals, then swap in the other one. Last edited by HughGordon; 07-07-2023 at 12:25 PM. |

Ok I'm going to run the .82, what fuel pump should I run. Will 255lph be enough? Keep in mind I'm not running e85.

If you want better spool get adjustable cam gears. You could advance the exhaust cam timing slightly. And adjust the tune. You could add more ignition timing before 10psi or so. Idk without seeing your data. Or get a 2.5L with a 207 you'll only get a power band from 4-8k
