Yes, it can be done. you have to machine the manifolds to accept new injectors, add a TPS [throttle position sensor] to one of the throttle shafts, make fuel rails to hold the injectors in place with a return to the fuel tank or build a surge tank [I like the surge tank idea because you dont have run a return line to the main fuel tank] and then you will need some sort of EFI system to control it all [SDS, Megasquirt, electamotive...]
It would make for a cool looking "60s style Old School Gasser" car.

If racing is the only intention, keep it mechanical. If it will be driven on the street, convert to EFI. _________________ Build thread: http://www.thesamba.com/vw/forum/viewtopic.php?t=212747

Street car, this is why i wanna go EFI.. I have a CB hideaway turbo setup that i want to use too. however, the throttle shafts on the hilborns aren't very well sealed. i suppose it will only leak air though. |

Machine the TB's for throttle shaft seals. _________________ Jerry...

I realize that your your current system is not pristine. But you have a piece of history. Please do not destroy it. There are many other options, motorcycle, CB and many others. I do not know where to buy parts for mechanical fuel injection, but there are many places to buy parts for EFI. Dont't get me wrong, I think EFI is the way to go, but please don't trash a piece of history to do this.
Thanks

I would bet there are more Hilborn throttle bodys then Weber IDA's in this country. My neighbor races Midgets & Sprint cars and he has a big box of broken T/B's and a bigger box of good T/B's and every Midget shop I have been in with him, is the same way. You can keep them pristine so some day a Midget car mechanic will get his hands on and install it on a race car so it can get snapped off in a wreck and thrown in the big box of broken T/B's.
Convert them, use them and enjoy them. _________________ Jerry...

Damn, back when I was hot and heavy into designing my EFI setup I found a place that had the weld in bungs.

Jegs, Summit, EBay, just about any shop that has tubing and flanges for custom intake/exhaust fabrication. _________________

There is a good chance that you can just have a machine shop machine the existing bungs out to the correct configuration. I was able to do it on my CROWER injection manifolds. Then you just have to make a fuel rail and retainer.
