Thanks for the info bud
This is enough for me to regain a little faith it my idea.
To clear some things up. - No, the Fieros never came with 2.8's in 1984. However I have a few reasons for why i think i can do this "easily enough" and why it's worth the hassle.
1. I have a free great running 2.8 Harness & ECU already out of the truck, ready to go.
2. Someone before me put in an 85/86 5-Speed that will bolt directly up and work very well with the 2.8 without grenading
Thank you previous owner!
3. This is my autocross car that has alredy been a little molested, frankenstiened, and toggle switched up, so I have inteded to swap a stand alone running engine from the beginning, regardless what engine, I just so happen to have the 2.8
4. The 2.8, while not incredibly powerful, still has arround 30%-40% more Hp & Tq, than my 2.5.. This in my 2500 lbs fiero will be a great gain, especially in the relm of RPM! My 2.5 falls on it's face at 3,700 most of the time. my 2.8 feels strong up to 5k and a little past though it may not be building power still by the numbers. Either way, in autocross this alone will be a huge advantage over the 2.5.
As i dig into my harness, trying to re-cap on what you said, I know i'll probably have some questions later. But considering i will mostlikely be taking some of this on today, i juat wanna make sure i got down what you were trying to explain in a general sens. --
Basicly speaking- are you saying the ecu has "out wires" that can run the sensors & engine as long as the ecu has a power and ground, and the other wires that go from body and chassiss just need to be separated from the harness? Give or take a few acceptions? Like the fuel pump relay system or whatever else?
