Twin Turbo Corvair with TBI
Posted: Fri May 21, 2010 5:57 am
Well I did it! I have it running that is. I took a 66 Corvair Convertible and started modifying it, the twin turbo's came of of an Audi TT which is also a 2.7L engine so they were just the right size. Then I fabricated the intake to use the typical GM V6 TBI unit. and then used the Megasquirt ECU with the relay board.
Why I'm so excited is because I know only the basics of electrical wiring and nothing about fuel injection! I just got a wild hair one day to do all this to my car which ran just fine they way it was.
I'm still in the beginning phase of the car running. It idles a little high and a little rich. I only have a narrow band EGO unit in right now so I'm going to change that to a wide band. And I don't know the condition of the IAC valve so I'm going to get a new one of those.
I have to read some more on how to tune it better and how to adjust the fuel tables. The challenge here is remembering what I read long enough to make the changes so it's, Read and go! About 4 years ago I had a stroke that affected my memory center and I was told I would never be able to learn something new! Ha,,,so far I think I'm learning and doing just fine. It may take me another 2 years to get it to the track for a time run, but who's counting right?
I couldn't get pic small enough to post here but I will gladly send them to anyone who might want to see the set up.
