I have a legacy turbo 2.0 from 92.
I just bought a impreza 2.0 engine from 98 with 5-speed dccd transmission, suspension etc.
My question is: Do the drivetrain from the old engine/transmission fit with the new engine/transmission?
Sorry, i am from denmark so my english isnot very good
The newer cars in the US use a 6-bolt configuration compared to the older 4-bolt configuration to mount the engine & trans together. However the two extra holes have alignment dowls on the older engines, so it "should" work just fine.
That is assuming your 98 uses the 6-bolt configuration. If it uses the older 4-bolt configuration, it should be the same.
The 6-bolt transmissions also have a stud for the starter, where the 4-bolt transmissions use the upper bolt of the starter to bolt the transmission to the car. The lower starter bolt no longer screws into anything, so that must also be considered.
