I have a 93 del sol currently has b17 in it, I want to swap a b20 into it, aside from engine, transmission, ecu and harness, what all will I need to do the swap. Any advice is helpful. Thanks!

 

You already have a b series you only need change the ecu and depend on what obd your car and new motor is, a few things need to be correct. i.e. Distributor

Is your b17 toast? Why you want a stock b20? If you go ahead at least swap the heads b20v.

 

Swap the distributors, injectors and alternator over from you B17 to the B20 and the rest will plug and play. Which B20 is it and which ECU are you going to be using?
