Re: Twin turbo, LS1, T56, Blow through Grand National
 

weren't the stock GN turbos T3/T4's of some kind? or were they straight T3s?

Re: Twin turbo, LS1, T56, Blow through Grand National
 

I dont think they are either. They use a 3-bolt triangle flange, and a standard T3/t4 oil drain does not fit either. Its a garrett turbo though.

I dont know where he ordered them from, but I can find out for you.

Re: Twin turbo, LS1, T56, Blow through Grand National
 

Cool, I guess I will need a drain flange too. Do you know where I can get one of those? Those turbos seem to be common on ebay.

Was that GN in bad shape to begin with or something?? That car is worth alot of bread in original condition, I can't see hacking it up like that. Any dime a dozen f-body would have been sufficient...

Re: Twin turbo, LS1, T56, Blow through Grand National
 

Only thing "hacked" on the entire car was the Trans tunnel to fit the 6 speed. And yeah, the car was in bad shape to begin with. Had a blown motor and transmission, about 6 inches of water in the carpet, flat tires all around, all missing trim pieces, some dumb ---- probably owned it before.

The whole reason it wasnt done to a F-body is because "They are a dime a dozen" And it probably wouldn't be as impressive I guess. Plus it ddint really matter to the owner of the value of the car. He has another GN in perfect condition with computer, turbo, and exhaust upgrades, and he is rich as ----.
