I'm planning to get a Honda Del Sol and swap a B16a2 engine and transmission into it. I know it will fit because Del Sol also came with b16a3. Del Sol are OBD1 and b16a2 are 0BD2. How to make the swap work? Will 99-00 SI axles work in a Del sol?

 

Yes they will.

 

Year make model. Del Sols can be OBD1 or OBD2 depending on the year.

 

If your del Sol is OBD1 just use an OBD1 ignition or viceversa. Is the same.
Make sure you use integra's rear engine "L" bracket. 99-00 civic's bracket won't work.
