domestic vs import turbo pressure?

[Tradition_F]

why is it our sixes can only handle 10 psi whereas the import sixers are up to 35? are our motors really that brittle? sorry if this is a newb question :spank:

wow. what stock motor can take 35 psi ? not tyring to be a D#$k but jsut wanted to know

Depends on what engine your talking about. Compression ratio plays a big role and how the engine is built. Ours was meant for NA. GTP version is for force induction that can go up to 20psi without any changes to the internals. GN can take a heck of a lot more psi. Guys at GN site have gone up to 30psi. Sy and Ty are the same.

Nissan 350z with 11:1 can only handle 5psi. They're really pushing it if they go higher.

Ours can handle 14psi without any changes to the internals. As long as fuel is adequate.

Skyliners and Supras can go up to 30psi.

Fastest LT1 with forged everything did 46psi Turbo.

Fastest LS1 with forged everything did 42psi with F1 ATi.

Re: domestic vs import turbo pressure?

alright, say i wanted to run 30 psi in a 3800, what would i need?

A lot of money!!

Those forged stuff are not cheap. Plus oil pressure might be an issue for us.

Re: domestic vs import turbo pressure?

alright, thanks for the insight :) im not sure if i want to tackle this or not...

P.S. any idea how much hp 30 psi of boost would add to our cars?

Not to mention our MAF would become completely useless.

Re: domestic vs import turbo pressure?

So if i knew that i was going to to F/I later on would it be better if i took an engine out of a GTP?

You cant...... Unless you can find a 90 degree Grand Prix motor. :D

Re: domestic vs import turbo pressure?

why 30? the fastes car are only running 25 psi and are running mid 9's....... why 25 you have any idea how much that would cost? $30K at least

ya, but those are v8s...

Re: domestic vs import turbo pressure?

first off you can take a morot out of a GTP, I am working on that projects right now.

Secondly 30 psi on our motors just isnt going to happen, the heads gasket would not come close to handling that much boost. thats to say you have forged everything.

umm no there not those are 3800 series II motors
