Q for all u smart peple

Will a Si or Dx 5 speed fit on to a 91 D15 STD motor?

I dont think so because the Si and Dx have like 21 splines and the std has only 20...i think.

I believe it will depending on what year your car is and what year the trans is. Give us some more info and we should be able to better answer your question.

shyt i just changed my right axle..........i forgot how many splines it was im doin the left axle next week so ill find out then
