Got a stock 12a ALL original. Bought a Cartech turbo setup Garret T3/T4internals turbo with Webber carb complete with intercooler and pipping for $550. The main question here is the turbo was on a 4port 13b, So im trying to locate a intake adapter plate to convert from the 13b 4port bolt pattern to the 12a 4 port. As far as the exhaust manifold, im just going to long gate the holes seeings they are not far offset. If someone can link me on the intake adapter that would be GREAT! Attached are some pix of the intake and some other pix of the turbo setup. See if I can do this attachment thing here. Will post more pix on the project as they go.

Keep r0tating!

i dont think they make an intake adapter that will adapt a 4 port 13b to a 12a.. i have seen a 4 port 13b to a 6 port adapter. but not to a 12a.

if you need an intake manifold you can pick on up for a 12a check out the forsale board here, as well as ebay.

if you want one new. www.racingbeat.com sells them as well as www.rotaryshack.com(they deal with turbo 12a's alot mostly carbed turbo so you should give them a call)
