I know what everyones thinking....another freaking T04 question...!! But just wanted to get everyones opinion. I might be running a T04 based turbo with .70 compressor side and .96 hot side. I also believe its a P trim. The motor is a large street port with 3mm seals done by MarvalSpeed. What do ya guys think? Turbo gonna be big enough for say about 450 whp at say 18 psi....any input would be appreciated...thanks..Tony

Turbo sounds about right for those numbers... TO4R? Large street port should spin that thing nicely!

Thanks man for the help. So those specs could be for a t04r or t04s?

Sounds more like my R.. (even bigger) mine is 67mm compressor and .96 hotside..

jdhuegel1...thanks again. So is your turbo a T04r?

jdhuegel1

Yeah. There's a vid a few threads down.. Initial start after the new motor and turbo.. V-Band was leaking in the first part of the clip... But you get the idea.

Do you all think the HKS Standerd wastegate will work well with this turbo? I believe he wategate is a 40mm. How much boost can the HKS standerd wategate safely handle? thanks....!!

Anyone..?

The 40mm will work fine. I've seen 35mm and 38mm gates work all the way down to 6lbs and up over 18.

I'm using a Tial 40mm on my TO4R.
