Gouky, that is an AWESOME custom crossmember! Way better than the one I tried to build (but ended up figuring out a way to use the stock one).

I'm not sure your CV joints are going to last at that angle though.

they won't last 200k miles, but they will last at least 60-80k

they are well within their limits and while i haven't put more than a few miles on that vehicle because of other issues i've done it on other ones before without issue. it's no worse than a normal 4x4 SUV that uses CV joints at the wheel.

What is that tiny little transmission??

1993-94 Subaru impreza FWD manual trans.

it'll only put up to about 200hp i beleive so it's not really a viable swap candiate for most people but when you're trying to fit between two cylinders of a radial engine, size matters

Do you happen to know if it uses the same gears as the later awd trannies? Because if so, the RA spec gears are stronger and could go in, which tend to handle about 300 ft/lb before reliability is too terrible. Stock wrx gears seem to be 250 ft lb, except for the last few years they updated the 5 speed to use the RA type stronger / wider gears, and obviously the 6 speed from the STI is a different beast - terrible ratios for drag racing, but the only affordable manual option for subaru people that handles big power

i would not be surprised if many of the parts were interchangable. it's the same transmission code.

but why do you ask? I'm actually done with that transmission and crossmember. the car is getting a different set of engines and a completely different drivetrain assembly soon.

It's nice, but I would still be disappointed it's not the real thing.

I saw a Faux-rrari F40 Fiero at last months' Cars & Coffee and once I saw the messed up lines 20 feet away, I was really disappointed. That's how I would feel if I saw this in person. Badges or not.

I just always thought an ej25 stroker wold make a good mr2 engine. 2.7 liters, 500-600 whp proven many times, and a lower lighter center of mass than stock. It might be low enough to try the flat 6's too...

getting a 500-600hp ej25 is not cheap. why not go with a motor with more displacement if you're willing to do a swap that complicated?

it would be no harder to put an ej25 as an LS series GM engine or a Ford Coyote engine. all three would need to be mounted longitudinally and the trunk at least partially sacrificed.

the ford and gm engines don't require more than a cam, intake an exhaust to get to those levels.

heck, with the ford option you can even get a bolt-on transmission from ford performance:

(yes, the coyote uses the modular bolt pattern)

you just have to remember, a $500 junkyard motor with $5,000 worth of parts to triple the stock horsepower is less reliable than if you had just spend that $5500 on a motor that makes the power you want to begin with.
