I have a 72 EA80 1.7 with dual weber 34 ict's. I am interested in converting it back to FI, D-jet I believe.

Has anyone done this? How hard, how much, can I still find all that is needed to convert it back?

Thoughts and comments?

you can get everything in the FI system for pretty cheap except a good MPS..

The swap is a good saturday job...with tuning...

Most of it is out there...

put a WTB in the classifieds...

I have enough 1.7 EFI parts in my garage that we should be able to assemble one working system. I'm more or less local to you, as well. I'd advise getting a new harness from Jeff Bowlsby. The only aircleaner I have is one of the old oil bath types, so you'd have to hunt up a '73 airbox if you'd prefer the paper filter type.

You might also consider this an opportunity to try an aftermarket ECU, which would mean not having to find a working MPS (I have 3 or 4, but I have no idea if any of them work). A pre-built MegaSquirt ECU would add $350 to the project, but wouldn't require an MPS, and would be fully tunable.

PM me if you're interested.

I dont think you will be paying much to put the stock FI back on there. The vacuum hoses will cost the most. I just spent over $70 in hoses for my 2.0. If James does not have it, I do. Just cover the shipping cost and its yours. I do not have a good MPS. I do have CHT, fuel reg, decel, intake runners, injectors, plenum, TPS, AAR, ECU, cold start, fuel rails...I just cant thow it away.

I even have a set of Euro spec pop up high compresion 1.7 pistons

I praise you for your choice to go back to FI

I don't have much in the way of hoses, but all that stuff needs to be new, anyway, or you'll have no end of problems. A working MPS is the single most expensive item in the lot, and I have one or two that might work. I have pretty much everything else, though.

Send them up to me for testing and/or recalibrating.....\
Test them with a vacuum pump. Pull 15hg for 5 minutes on the mps and see if it holds the vacuum. It will if its good. Forget the sucking on it test as you can't pull enough vacuum.....
