where to find one? there aren't exactly too many in junkyards can it be bought from the gm dealer? if so what do i ask for (as far as year and and stuff are concerned) and how much should i be expected to pay?

Might try asking on the PROM board. they would be able to help Im sure.

Bort62 just did this swap on someone's GTA with a vortech and said that it is running great!

Good luck!

I quess they come in turbo sunbirds from the 80's and also I have seen them on Ebay

you can get them from autozone and other parts stores, and a gm parts counter. Most autozone's don't have them in their stores, but you can buy it from their website. it's 79.99 + 75 core charge. I got my latest one on ebay for i think 100 buy it now.

the autozone part # is 77-7749

if you go to parts stores for one, just ask for a ecm for one of the cars that came with the 749, like say a 91 gmc syclone.

I'm interested in doing this as well.

I Purchased on off of EBAY last year for 40 bucks. I ended up selling it for the same.

They also came in some late 80's quad 4's

As long as you use saturated High impedence injectors, just use a 7730, wire it to match a SyTy and load $58 code changed to 8 cyl into the prom. Simple, down and dirty. BW
