Many people race Lemons for the cheap track time, others in an earnest attempt to win, and some as an excuse to build a silly car. Texas-based team Nader H8Rs probably falls (at least in part) into all three categories, but when you’re racing a Subaru WRX-powered Corvair, there’s a bit …

This makes so much sense. There are a bunch of guys who are all about mid-engined V8 Corvairs, but the engine ends up practically pressed into the drivers back -  it's loud, hot, and not much fun to drive.  Whereas sicking something more compact in there with a proper transaxle makes sense. Kudos!

Corvair transaxles are improper? devil

Yes, they are strangely fragile when you bolt an engine with triple the torque  to an un modified one....

They are surprisingly strong when you put a 4 spider setup in them.  The trans (66+) was a Saginaw that is very similar to the full size car version.

I find the engine swap interesting, and it was one of convenience.  Dropping a FWD drivetrain in the back seat is a good way to go.  I happen to know a Speed 3 has almost the exact wheel track as a late Corvair...

Nice to see a Corvair racing.

Just speculating of course, but here I go.

Pull the high beams and front turn signals out, vent the hood and move the radiator to the front.

Put a scoop on the rear engine air vents at the base of the back glass.  Move the intercooler towards that air vent and remove the back up light assembly to let air out of the engine bay area


No one asked but I gave my opinion anyway.

If the radiator is moved to the front a second electric water pump may be needed. Water has to flow all the way around. Single stock pump might not handle that well.

Rear mounted radiators (even condensers) have always been an issue with Corvair engine conversions.  Not sure the water pump pressure is an issue, I don't think that is normally a thing with a V8 conversion.  Front mounted radiators / condensers are certainly the best option.

The removal of the rear glass is probably a good idea.  Remove the rear side windows and use them as intakes.

Just graft the front end of a Corvair on to a Tesla, that would be an improvement.

If you use a modern transaxle like a Cayman S there's tons of leg room.  Like my 68 with a Cayman S trans and 2016 LT1

Wait, that's yours? surprise Wow, beautiful piece of work. I'm very jealous. On the Corvair forums most people seem to want to go the Crown route. which makes little sense to me.

My dream is to restomod one via a Porsche or converted Subbie transmission fed by a LFX in the rear like god intended.

It is indeed mine.  I looked at Crown but the fragility of the transmission combined with the leg room drove me away.  Others have successfully used C5 vette transqxles, but again leg room issues.  My father has this one.   930 trans, LS1 from an 03 vette, going on 13 years without issue.
