thru my experience put it 2T Carina engine in my ke70 station wagon, the only major issue is.... the crossmember. 4K and 2T crossmember is not same in size. the length and the screw hole......resulting have to custom the 2T crossmember
and the T50 gearbox will hit the firewall around starter area.have to knock the firewall abit.
also custom the longshaft, becoz....u can't put in 4AGE's rear axle into your wagon.have to use your stock 4K coz the come with leaf spring. so far i found none expert can modify leaf to coil spring modification.
even though 2T and 4AGE are different,but the basic thing that u need to know is....
1. can the 4AGE crossmember fit your wagon without any problem? or have to modify it?
2. does the T50 gearbox hit the firewall?
3. does the 4AGE longshaft is kind of plug and play to my 4K rear axle?
if u need the 4K wagon's crossmember for your comparison, call me. i can lend u mine, but please return back la.....
