modifications to the subaru drivetraim

hi all. i have a question regarding modifications to a subaru drivetran. i'm in the process of designing a mid-engine, road-going space frame chassis, and i'd like to use a subaru drivetrain, preferrably a wrx engine/transaxle. my question is of an academic nature: would it be possible to safely disconnect the propshaft to the rear end, thus sending 100% of the driving force to the front wheels? thanks a million.

I think you would have to sever power from the transmission. Since you would eliminate the center differential and back, all power would be sent to the remaining front(or rear) axle assembly. Will the driveshafts and etc. be able to handle the power is the question. or lots of wheel spin...

Some older Subaru models were avail with a turbo and front wheel drive. You would want to find one of these trannies or use the part from that tranny that bypasses the center diff in the awd models. I would think the tranny could handle the hp in fwd mode if it can handle it in awd mode. Just make sure you use heavy duty shafts. I have seen an article is sport compact car mag that converted a wrx to rear wheel drive for drifting. The subaru tranny was originally designed as a fwd tranny then modified for awd use so it would be stronger in fwd mode than rwd mode. The awd mode is hardest on the tranny because of less slippage at the wheels and all the stress is in the tranny.
