Front engine mount

love the braaaap
Yes, omp is oil metering pump. I don't know what its like putting an S4/S5 engine in an -SE, but I remember trying to get the FI to work in my 82 when I swaped it in. The wiring was a nightmare.

I got the wiring harness and the ECU with the engine I bought, still think it's going to be a nightmare? I'm not looking for that at all. I do have the option of only using the S5 block with the SE fuel injection and such. That should make it much easier. I was told everything from the SE should bolt up to the S5. I'm just wondering how much hp I'll lose over the full blown S5 if I do that.
And as you might have guessed I'm not good with acronyms...wtf is TPS? wtf is a TB?

TPS = Throttle Position Sensor
TB = Throttle body (where the butterflies are)
The SE uses a single TPS sensor, but the S5 has two. The wiring shouldn't be too bad, since you have the engine harness. You may have to do something for the ECU power and such, but it shouldn't be too bad. You will lose power if you use the S3 setup. Stock, the S5 has about 25hp more than the GSL-SE. I would try to keep the S5 stuff if you can (or you could just give it to me ). I think the main issue will be getting the OMP working. You may just want to premix.

It is partly due to the higher compression, but the main factor is the intake and higher redline. The compression isn't much different either (9.7 vs. 9.4). The higher redline of the S5 won't be useable with the S3 intake, because power starts to drop at 6k rpm with the GSL-SE intake (peak hp point for the GSL-SE). Beyond that the power will continue to drop. The S5 has larger throttle plates and intake runners so that it can flow the air required at high rpm/load combinations.
The other source for the increase in power is the more advance fuel injection system (and ECU controlled timing) and the better flowing AFM (Air Flow Meter).
The S5 setup shouldn't be that much harder than the GSL-SE. I would at least give it a try. I want to go the other way myself (s5 intake on a GSL-SE engine).
