Anyone know who sells the 3 bolt to 4 bolt adapter flange? I seen it talked about in the sticky, as my headers have 4 bolt flanges and I'm running 2 GN stock turbos on my SBC. The sticky did not post a link on where to purchase them though.

Turbonetics made these, you should call them direct or Jack Cotton who is a dealer.
 
OMG! Someone that hasn't heard of Jack yet! He is one of the premier Buick vendors. You can give him a call at 413-789-0531 or check out his website cottonsperformance.com. He will be a great help over the phone if you want to discuss what you are trying to do.
 
apparently it's a T4 to GN 3 bolt adapter and I need a T3 to GN adapter plate, any thoughts..? I'll have to call up cotton performance tomorrow.
 
i also need

digging it up

did you find one?

i need it for a gn 3 bolt turbo to typhoon 4 bolt exhaust manifold

thanks
 
well
its more square and needs to be more rectangular

the hole in the middle needs to be rectangular instead of round

only 1 of the four bolts line up to the exhaust manifolds four bolts and it appears you will cross drill into the others trying to make this possibly work

crazy but it cost $30 brand new when it was available-without all the bs work
