A Gt4088 is a 65mm turbo, actually smaller then a 6765 (t67). It takes a 4094 to get up to the same size as a 67mm. The 4094 is i think right around 68mm.

The Gt4088 is a real good turbo, if it was 2001. The 6765 billet will make what you want. But honestly, the 6262 billet will do it as well. Search the billet 6262 vs DBB T72. On 18.5psi the billet 6262 made 58X. So you can get the 6765 but if he only wants 600, why get a 900hp capable turbo? Get the 6262 billet.

 

We just found out that there is e85 on pump here, so i think he is deciding on e85 and the 6765. 600 was his min whp he wanted. so basically... 25 max psi... whatever whp he makes... is what he gets.

 

If thats the case why doesnt he just get the biggest turbo that will fit in the engine bay?

 

um, not only is he not getting a better power band, he would be losing what he already has with anything too large.

 

I was being a smartass. Between the 6765 and the gt40 i would choose the 67 all day any day on any car. But the 62mm will do the exact same job, spool up probably 800rpms faster and make probably 60 more foot lbs or tq.

I was being a smartass because it doesnt really seem like a good way to look at a build. Minimum 600whp on no more then 25psi. Those are dyno queen goals IMO.

 

--- LAWL... it is a dyno queen. He is a dyno king. DK YO!!!

 

Thats why i said just put the biggest turbo that he can fit in the bay.

Good luck with it.

 

--- Thanks :D

That car is saweeeet!

 

You can make 600whp with the turbo you already have. And why only 25psi. If it's built right then max out that turbo.700+

 

If you buddy wants to be a dyno queen he built the wrong motor IMO....lol

Are you refering to a Journal 4088 or a divided 4088R and a open or divided manifold? I would think a 4088R with a good TS manny would outspool a 6765 but make less power, I am pretty sure that 6765 is a laggy **** but makes big power for the queens.
