where can i get the parts i need to make my 12a out of my 84gsl into a 12a turbo? do i need to buy the motor, or do they make conversions?

hornbm

are you talking about a blowthrough car setup or the stock 12at from japan?

Keep an eye on www.ebay.com There are a few kits that show up every once in a while. They look pretty complete mostly.

hornbm: I have an 84gsl, and i am trying to make it turbo, i am looking for either a conversion kit, or a jspec motor, either one, i really dont care...

Here's what you need to turbocharge your stock 12a:

-TurboII Exhaust manifold - oval bolt holes, grind exhaust path 5mm inward on each side.
-TurboII Turbo
-TurboII Wastegate
-Nikki(stock) Carb w/mods done to handle boost
-Turbo Hat for Carb
-GSL-SE Fuel pump
-Rising rate Fuel pressure regulator
-Drill hole/put in fitting in engine front cover for turbo oil return line
-T fitting where the oil pressure gauge gets it's reading from for turbo oil feed line
-Remove vacuume advance and weld centrifugal advance on the distributor
-Custom exhaust

Whoops, I missed something. You also need the intake manifold from a 12aT beacuse the stock one WILL NOT fit with a turbo there. Or you could find some way to extend the turbo out away from the engine, but I think the 12aT manifold would be the easiest way if you can find one.

well if you want to do that forget the modified nikki. The 12at was fuel injected like the GSL-SE.

Instead of trying to find an ultra rare 12at intake manifold, look for a TII one and make an adapter plate.

coldy and hornbm:

Would it be possible to simply modify a TII intake manifold to fit the 12A bolt pattern (just as in the case of the TII exhaust manifold)? Obviously you'd have to use the throttle body and such from a 13BT as well, but those are a lot easier to come by than a 12AT intake manifold (as coldy said). I think it'd also be easier to modify an existing TII manifold than machine an adapter plate, too, but maybe I'm wrong. Does anybody know for sure?

hornbm

youd have to use an adapter plate because the ports are father apart on the 13b. Its not a bolt pattern issure the ports are physically father apart because of the 13b block being 20 mm longer.

The ONLY way to get those manifolds on that block and have them work correctly is to use a adapter plate.

They can't be THAT rare, I'm using one

why not just go with a nice cheap s4 tII setup and leave it bone *** stock?
