Turbo ?'s
 

How big of a turbo in mm., can a stock v-6, like a 3.8 or 4.1, stock.

well bottom end i think i've seen people pushing either GT35Rs , or, as my friend has, a GT4088R. But only about at 6-8psi for a stock motor.

take a look in the forced induction area of camarov6.com

I'm thinking of a 71mm onto a stock V-6 boost it little at a time to see how fast i can get it to go without blowing it up, if i like V-6 turbo then build a wild one, then let it eat.

yeah man, even the V6s love boost, not just ls1s. when my buddy first put on a 70mm from ebay on his car (yeah i know, poor turbo but it worked for awhile), he was pushin 8 psi and put down 415 at the wheels before the bottom end finally blew.

JR, are you talking about the 3.8 used in the 96-02 F-Bodies, or the 3.8 from the 80's found in the turbo buicks and similar cars?

Or the 8.5:1 compression version in a GTP...

doesn't matter chevy,buick, no 4.3 gm though.

NMCA at Atco !!!!!
 

i just found out that Atco is have NMCA race there june 6th - 8th. 08', now i want to put my sbc back together to run the pro-stock class, and i took all my stickers & numbers off the car. Dam. JR.

That would involve swapping L67 internals into an L32 block though.....the FWD blocks have no provisions for standard RWD engine mounts.


I was just asking since the 80's 3.8s are a completely different animal than the mid-late 90's ones.

the Cartuning Performance turbo kit for the grand prix put down 296hp and over 400tq on a STOCK n/a 3.8, with a T04-B P-trim garret turbo, open downpipe...they also have a PT-61mm upgrade which they say can support 600+hp

Not true, if you have fabrication skills. It's not that difficult. A buddy of mine is swapping one in a G-body.
