S5 Harness And Ecu/s4 Motor?
Hey Guys Im Kind Of A Fb Guy, But A Friend Of Mine And I Are Wondering Can We Use The Stock Wiring Harness And Ecu In A 90 S5 And Swap In A 87 S4 Turbo Motor???
Will This Work?
We Have Installed Everything Incluning A New Hp Fuel Pump And All We Can Get Are Flame Shooting Backfires.
Thanks For The Help.

If the car is a 90 FC, And the engine is an S4. Yes you can use the engine. I would recomend using the S5 lower and upper intakes And swap out the manual OMP and use the s5 front housings.

If the 90 harness and ECU are not Turbo ones, the timing and map will be all off. The Timeing will be off slightly anyway, just using a S5 ECU on a S4 block, so you will probably need to compinsate for that anyway.
