Insane GT build Up (Talon mitsu 4G63 engine)

Thought I should fill you guys in on the progress with my project GT.

Took a couple pics of the new parts I have getting ready for the Opel. I got an engine from a 1990 Talon TSi (which happens to have a Hyundai valve cover), the whole wiring harness/coil pack/throttlebody from the same year car, a Precision Turbo & Engine SCM61 turbo rated at 620hp worth of flow and a 3" GM LS1 MAF. I already had a K&N Typhoon filter, so I attached it to the MAF. The suspension was completely disassembled and covered with POR-15 and BlackCote topcoat.

The engine block itself is currently at a machine shop getting a full rebuild plus JE 9.0:1 forged pistons, ARP head studs, ARP rod bolts, ARP main bolts and a metal head gasket. I'm also getting a Holley fuel rail and Holly 65lb/hr injectors to go along with it. Still searching for what to do about a tranny and rear end though?

Should be interesting next year. :D

With proper tuning, it should put down somewhere around 450 rear wheel horsepower. I'm looking forward to that...

I'm pretty sure the 79ish Dodge Challenger and Plymouth Sapporo(?) have a 5-speed that'll work for you. Possibly the trucks as well. Looks like the clutch is at least the same. Good luck!

Thanks found the pics in your updated post! You got a lot of work ahead of you! Your new powerplant looks great and a good fit!

Thanks again,
Thanks, but the 4G63 swap is now cancelled. After a lot of work trying to source parts and make a FWD-based engine RWD, I gave up on it. Just not going to happen without a huge amounts of funds.

I'm exploring other possibilties right now. Possibly 3TC Turbo, maybe 4AGZE, or maybe just a KA24DE out of a 240SX. Who knows. A guy here has a BMW M30 motor (3.5 litre straight-6, 210hp) swap package he would sell for $800. That might be an option as well. Keep it "all German". :cool:
? 4G63 ? what tranny?

Can anyone tell me what tranny would work with the mitsu 4G63 engine, I don't want my shifter behind the seat, the closer to stock it looks the better.
Or does any one have an oppinion or a rx 7 rotary implant vs the 4G63 turbo, either way my "lil red wagon" will have a turbo and spending 10 grand on an opel engine with a turbo that can't handle 4 pounds of boost without running some exotic fuel that costs $8 a gallon is not an option. As bad as I have to say it, unless anyone knows if a rear drive porce tranny would come close to fitting ?
