Does anyone know if the 6spd STI tran will fit on the 2006 WRX block?

 

Yes, it will. The STi 6 speed will fit 02-05 WRX, and the 06 WRX trans will fit the 02-05 WRX, so they are all interchangeable.

 

COOL! Thanx for the info!

 

correct me if im wrong, but i heard something from a subaru specialist about different drive lines and linkage. but then again i wanted to put an sti 6speed on my 01 2.5 rs

 

Sure, that's correct for any Subaru. He asked if you could mate the 6 speed to the 06 WRX block. And yes, you can. Ofcourse you will also haveto install the 6 speed shifter linkage (which usually comes with it if you buy used), 6 speed clutch & flywheel. On top of that you'll need a driveshaft (from a 4EAT, I believe), unless you are going to change out the whole rearend, then you need the R180 rearend...but when you buy that you usually buy the axles and Brembos...seriously, it's never ending. It's not as easy as just buying a 6 speed and bolting it up.

 

i think all EJ motors will interchange with any tranny
