i'm a second gen owner (turbo II), and my friend is planing get a first gen, we both know much about second gens, but very little on first gens, our first major project is the 12AT, we know it's fuel inject'd, and that's what we like i.e. we don't know **** about carbs..well corksports selling some engines but no ECU/Wire Harness, etc... well is there a write up on a 12AT, and please don't try to lure us into 13BT swap or anything we just need the info on 12AT SWAP, YES i've search, but on every post it says (SEARCH U'LL FIND SOMETHING) but end up never finding because everyone always say search.

Problem with the 12at is the like 6lbs of boost cut off. Because there is no intercooler. And the motor runs out of fuel due to only having 2 800cc injectors. But if you look on the www.mazspeed.com forum. You will find some links to 12at stuff.

S2-13BT

If you're dropping in a 12AT, use an aftermarket ECU (haltech, microtech or something). Fit an intercooler and use a 13BT's turbo as the 12AT item is tiny.

I'm sure there was a decent thread about the 12AT in this section somewhere...

having no intercooler and a small turbo is a benafit in some ways... less turbo lag

Exactly. With a small turbo, you'll get the power faster.

here is how to solve the problem" fist off an intercooler is also a safty device and a performanve mod. it greatly reduces the air charge temp wihich cuts down on detonation. it will not be that hard in my case to run an intercooler i will jsut chop off the intake pipe between the turbo and the tb. i also put a bov on the rear side of that pipe where there was a "pop off valve "of sorts (i dunno what it was exactly but its not importtant) as for being a little turbo it is. but i'm told a turboII turbo will bolt to the ani fold if your looking for quick cheap power. no to mention you can have those rebuilt and upgraded. in that case also you can buy aftermaket down pipes that will bolt up to the turbo. 12at has none. i am haven't a custom exhaust made fromthe turbo to the tail. (no cat and a striaht throuhg muffler. 2nd to make the 12at reach any real power you will need to get a port. i' mgetting a very large street port soon after it runs. how far along are you i would like to tak to proly one of the only other people in the us doing this.

You get no power faster! lol

I was planning on the TII turbo... a bit bigger, although I'm not planning on running massive boost anyway. And intercooled is the way to go!

As for fuel injection... sheesh I'm not that patient. Would be interesting though.
