So, this is an 'I have this, not sure if I want to keep it' thing. IB4FirstWorldProblems.
Anyway, I have my Subaru Baja, it's paid off, but now I'm not sure if i want to keep it. I bought the non-turbo version because I waited for 7 months for a turbo model, and none came up, and I figured I could swap the powertrain. If I bought the turbo model, I would have eventually tried putting a 6MT in it from a STi anyway.
So here's the problem: You can't swap the hub/knuckles for some reason I cannot yet fathom (the STi used a 5X114.3 hub, except for the SVX and B9/Tribeca, all other Subarus use a 5X100 hub, and apparently the trailing arms don't work). My original plan was to buy a Baja, pull the engine, trans, rear diff, axles, hubs, knuckles, brakes, wheels, tires, wiring, and computer, and start swapping it out with STi gear, starting with the hubs/knuckles, axles. I'd do the trans/diff/axles/hubs all at the same time, then I would build a new engine for it, starting with an STi turbo motor.
So, I do have options. I could keep the 5X100 hubs, and make hybrid axles. This way I could run the 6MT and the beefier rear diff from the STi, but the hubs, brakes, and especially wheel bearings are going to be a huge weak point. Alternatively, I could run a WRX 5MT, but... Here's the problem: Subaru's 5 speed manual transmissions are based on a 1980's 4 speed manual gearbox, which is just an updated 1970's box. Basically, they're weak. The 5 speeds use a horizontally split transmission case, which flexes under heavy load, and the actual gear shafts can move in relation to eachother, and since second gear is at the far end of the case, the teeth can go out of mesh, and it's fairly easy to strip the teeth off second gear. The 6MT box in the STi uses a case split vertically, which is extremely strong. A guy drag racing in Puerto Rico ran 800+ ft lbs of torque through a stock 6MT for hundreds of really hard launches before second gear gave up. Built 5MT's will break at 300 ft lbs of torque or even less.
My other thought would be to get a second car... The Baja is 3,800 lbs with my fat ass in it, which makes it the heaviest Subaru I've ever owned. My Legacy L was 3,550, my Legacy GT was 3,500, my WRX was 3,200, and my GL Turbo was 2,800 lbs. I've been keeping my eye on local lots and craigslist for a 1994-1999 Impreza to come up for sale. It wouldn't be hard to get a high mileage car, and build it how I want to build it for speed.
Oh, why is this even an issue? I want to build a 2.65 liter stroker motor. I'm aiming for 450 ft lbs at least, so a 5MT probably won't be sufficient...
Also note: The later 6MT's used in the Legacy, WRX, and Forster are based on the 5MT, so I'm assuming they have the same weakness as the older 5MT's.
And finally, I could just sell the Baja and buy a STi. This would actually be more expensive than buying an old Impreza and fully swapping the crap out of it... Or I could sell the Baja and get a Corvette. Not sure what to do.
Cliffs Notes: Bought NA Baja, can't swap how I want to, should I go with hybrid axles, or another car?
