The car is currently carburated so I will just wire it for what will work best (ODB0, ODB1) and I don't have room for a turbo unless I want it sticking through the radiator and front grill. The motor in the car was an old E-series in which the intake and exaust are both on the backside of the head. I am unsure if I can fit a SOHC let alone the deeper DOHC. Will the 90-93 Teg motor bolt to an 89-91 SI tranny? I see that motor refered to as a ZC but some people say it will not bolt up to the Si tranny and you have to get the JDM ZC to bolt up.
