RustyBrat Posted February 19, 2015 Share Posted February 19, 2015 ive always been curious how people manage to do straight axles and a transfer case with these transmissions, since they are primarily fwd Quote Link to comment Share on other sites More sharing options...
Uberoo Posted February 19, 2015 Share Posted February 19, 2015 (edited) Power normally goes through the front wheels,but when needed power is mechanically coupled to the rear wheels.Just like a normal 4wd system,just in reverse.Thats why you can't use 4wd on dry pavement because there is no differential between front and rear, so any turns will bind up the drivetrain. In a transfer case setup,the subaru transmission is locked in 4wd.The power goes to a transfercase and it is exactly like a normal 4wd system at point.

ferp420 Posted February 19, 2015 Author Share Posted February 19, 2015 i could be wrong but im pritty shure the brzs are rwd only basicly a toyota trans that mates to the subaru motor im just woundering if it wil bolt up to a ej 2.5d thats already in the car Quote Link to comment Share on other sites More sharing options...

Uberoo Posted February 20, 2015 Share Posted February 20, 2015 Short answer: No, they are not wrong. Long answer: using a normal subaru transmission not BRZ,in rwd all power must flow through a small set of transfer gears that arn't really designed to have 100% of the torque flowing through them.Same with the rear suspension and axles. So a rwd subie for RWD shenanigans is fun but it will blow transmissions and rear axles... Quote Link to comment Share on other sites More sharing options...
Uberoo Posted February 20, 2015 Share Posted February 20, 2015 As far as using the BRZ transmission with EJ stuff-It might work.The bolt patterns look similar and probally are because its a subaru, but the starter on the BRZ transmission is opposite to an EJ engine.There might be enough room to make it fit but...

One would need to cut an opening on the drivers side of the bell to mount a Starter in the EJ position. OR..... Cut the bell area of the passenger side of the EJ25 to make room for the starter snout.

monstaru Posted February 20, 2015 Share Posted February 20, 2015 Just use a normal EJ 5 spd with a solid coupler, instead of a viscous coupler.easy, and cheap. Quote Link to comment Share on other sites More sharing options...
Vegablade Posted February 20, 2015 Share Posted February 20, 2015 Just use a normal EJ 5 spd with a solid coupler, instead of a viscous coupler.easy, and cheap. This would be the correct way. Then just get some plugs for the transmission. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted February 22, 2015 Share Posted February 22, 2015 Just use a normal EJ 5 spd with a solid coupler, instead of a viscous coupler.easy, and cheap. Still puts the output through the transfer gear. Quote Link to comment Share on other sites More sharing options...
