Ok, So I got the new trans it's a 5-speed out of an Si. I have been told that the transmission will bolt to the D15 block without a problem, so the only prob that I can forsee is the flywheel, clutch, and pressure plate from the initial 4-speed not being compatible with the new transmission. Does anyone know if this is a potential problem or is it simply bolt on easy? The guy I got the trans from didn't know if it was going to be a problem.
 
unless your car or motor is a 1988....it will fit fine....i had a 4spd on my d16a6 si engine that was supposed to have a 5-spd....so i dont see why it wouldnt work vise versa
 
Like I said, I was told the bolt pattern is the same. It's the flywheel/clutch/pressure plate that I'm wondering about, can it be interchanged between the 4-speed and the 5-speed without problems or is it application specific?
