1966 corsa vert, Resurrection!

[Mike D]

tough crowed, i figured a fuel injected, distributes ignition system fitted to a corvair would get a few more questions,...

[Scott V]

maybe not such a tough crowd - just the crowd doesnt have more questions. lol

cool project & its good to see another vair w/efi.

heres another engine w/efi throttle bodys & crank trigger coil packs.

this is something i would love to do, but don't know where to begin with efi

[Mike D]

its a long path, and one im still not finished with,, But the benifits are pretty awesome.

the best place to start is with some reading, and looking around at EFI systems there are a ton of different ways to do it, you just need to figure out which one you like the best!

Many of us in the "classic hobby" aren't knowledgeable enough to start down a road like this on our own. The cost of parts is prohibitive to begin with and then to pay someone to install and get it working properly costs more than most of these cars are worth. You seem to have the knowledge, skill and parts sources to mix and match parts from different makes, models, etc. for this to be an economical conversion. It's just not in the realm of reality for many.

Seeing what others have done is interesting and may influence me in the future.

The EFI/DIS system outlined in the following website (and also marketed by Clark's Corvair Parts) was developed for the two and four carburetor Corvair engines, but utilizes only two throttle bodies and two block-off cover plates (for 140 hp engines to eliminate the secondary carburetors).

The above system was installed on a Corvair sedan that was entered in the October 2013 Corvair of the Month competition.

start w/looking at the way other guys have done the conversion. theres lots of pictures & info you can use. you can get some ideas at http://www.american-pi.com & http://corvair-efi.com/

you dont need to start something like this on your own. there are guys that have done this & would probably help you & there are guys that have kits - ready to go. see "www.american-pi.com" & "corvairefi.com"

the cost of the parts arent prohibitive & you can get efi for less than some guys put in tires/wheels. anyone can put efi on a junker car & thats cool if someone wants to put a $1500 efi system on a $1000 vair. the car has to be pretty junkey & the efi system pretty expensive to make the efi system cost more than the car is worth.

All said and done, im into my EFI swap for about 600$, this includes the fuel pump, and wideband lambda sensor.

i still need to neaten things up under the hood, things like fuel lines and wires are not tidy yet, and my throttle linkage needs a revision..

also, maybe somebody can set me straight. I have never heard of a hydrolic throttle linkage being used, however in concept it could have a lot less moving parts. Is there a good reason not to do this? am i missing something on why its never been done before?


Junkyard parts are great, Although we all like to have a bunch of aftermarket names on out mods, We need to acknowledge that most parts installed on cars from the 90's are a pretty significant improvement over anything made in the 1960's Thats just how tech works Its also nice to use parts that are on every NAPA and autozone parts shelf, that way if something does happen i don't have to go on a long hunt for a part.

i do have some background in EFI, which does help a lot, for work i tune turbocharged saabs (MikeDTuning.com).. Those cars force you to learn a whole lot, very fast

Expect more to come, the car is getting a roll cage this winter, as well as the rear brakes converted to disks as well

hydraulic throttles have been used on vairs & buggys. they are more expensive & more work than a cable - thats why you dont see much of them.

I have interest, I can read a book, I have the crank trigger knowledge, I have the coil pac knowledge, I have worked on cars with throttle bodies, the only thing that I can't figure out is where the money is going to come from. I would like to convert my engines over , anything would be better than the crappy carbs we are stuck with. Make up a parts list from the junk [ salvage ] yard so we can do this conversion on a budget on a as found basis. Thank you.

If you follow the link that Brad posted and click the Corvair Fuel Injection link there you'll see a parts list at the bottom of the page plus a lot of pictures too . My thinking was sort of along your line of thinking but after reading their parts list me now think it better to buy theirs For example , the Water Temp Equivalent (WTE) method they came up with that fools the computer into thinking its' still on a liquid cooled engine when it's not . How much time could you waste trying to figure that one out ? I knew a guy down here years ago who put an S10 throttle body on a manifold that fitted to both carb holes. He spent more time trying to get that temp sensor properly located and sending the correct signal to the computer than any other single aspect of his set up . Granted , he derived a lot of satisfaction from it afterwards but even then he had issues with it . For me , working more time to get this kit is worth it over wandering for who knows how many hours in junkyards although some people love doing that . Maybe you have access to a machine shop and can make some of these parts . I would love to put this kit on my car and even then it isn't plug and play . I was a little bummed that I would still have to get the throttle bodies myself but .I think they did a great job with it . Good luck to the OP with his set up . Please keep us posted on your progress with pics too if possible . I'd like to see some other computer and TBI's used over these perhaps . Maybe this kit could be ordered minus the computer and use your own configuration ? Happy holidays AND MerryChristmas

The first, and most important thing to do research on if the Ford EDIS ignition system,, Its a gem, and it takes a ton of headaches out because it handles the crank triggering, tach output, and high amp coil drivers all in one easily available packages,, Even if you want to keep a carb on the car for fueling, you can loose the distributor and run EDIS with a very affordable Mega-jolt ecu setup,, i ran the car super briefly on EDIS with a carb, and it ran 10x better than it ever did with a dizzy. I hate distributors.... This alone is a HUGE upgrade for the car, and you can do the whole thing for about the same money as many ignition upgrades, Just this is the final word in an ignition system.

Then introduce yourself to mega-squirt, It can be a lot at first, and will never make sense until you have the ECU in-front of you, and are soldering the board together. Sadly you just kinda need to take the plundge with it.

From there, figure out how to do the throttle body(s) i used motorcycle parts,, and am still not sure if it was the best route,, But its done now.

Water temp equivalent was easy, i have a head temperature sensor, and use that instead, Since i can adjust all my maps very precises its just tuning a different way..

I bought my first em , a 63 coupe last summer, the car sat for a long time and needed the carbs rebuilt, tank cleaned etc. After I got it running I was surprised how many people I ran into that had corvairs at various times in their lives. They all loved the car but got rid of them because of carb problems. I got my carbs figured out now but the distributor bushing is worn and needs to be replaced. I'm going to look into this a little more as I know the carb problem will return.

here are some quick links to the EDIS system, The one below is probably makes the system seam much more complex than it is, However it is also very in depth, and explains everything.

and here is the Megajolt ECU, this only does ignition, you can also use a standard Megasquirt ECU for ignition, and then also have the option later for fueling,, Its really up to the opperator.

and a good place to look for megasquirt products, EDIS trigger wheels, and lots of other odds and ends

i got the throttle linkage sorted today, and took a few pictures of my (super messy/ project status) engine bay.








the throttle bodys sound mean at idle, it just feels stronger with them, However i think the throttle bodys i used are oversized for the car, in reality, going with a smaller bore TB would make the intake fabrication easier,, i had to find some steal cones, which are remarkably hard to track down
