I have a 90 gxl with a blown motor, cracked rotor housings to be specific. I just got my hands on a 88 non-turbo car that has been wrecked but has a good motor. I was wondering if anyone could tell me what would be involved in putting the motor from the 88 in the 90. I know that the series 5 motor in the 90 and the series 4 motor in the 88 are different but since I have the complete car I can swap any parts needed. I was also wondering if there are any parts I should but on the 88 motor that are on the 90 motor, such as the intake. If anyone has any information on this engine swap and could help me I would greatly apreciated.



Thanks,

Noel

 

Heres the S5 parts you'll need to make a straight swap:



Upper and lower intakes......just easier to swap both as a unit

Fuel injectors

Front cover so you can use the stock OMP



Other wise you should be good to go.Let us know how it goes.

thank you for the help. So I won't have to swap wiring harnesses or anything? I should be doing the swap next week I will make sure to keep you updated on it.

O your using the stock S5 intakes then it uses the stock wiring then.Makes for a easy swap.But the extra wires are nice to have if something fries up on you or you need to fix a harness.

 

That's good to hear. It will be easier not swapping wiring harnesses lol. Thank you for your help.
