AS far as I have been informed, to compensate the rotation problem you will need to take your tranny apart, and flip the differential, thus flipping the ring gear and allowing it to go the other direction. I too am interested in such an endevor......but you first The cost is a lot better. There is a guy local to me that installs a 911 type cooling system with impeller, and shroud onto sand rail corvair engines. This would get rid of that scary looking 90 degree BS on the stock. Can you make the displacement bigger? How big? How much? Keep us (me ) posted.

Could you use the 901 trans from the 911?

You really only have the option of installing a reverse cam and distributor drive gear. This way, you dont need another transmission. If you reverse the gears in any tranny, you will be applying the power to the coast side of the transmission which will wear them out rather quickly. Clark's Corvair sells a kit which does this and it's around $200. They also sell a bellhousing adapter so you can use the clutch,starter and flywheel from a 914 for around $300.

Gotta change over to the 914 nose cone and shift rails which requires tearing the damned thing half apart anyway. Might not be worth it.

Later,

One Corvair-motor conversion that I know of used a 911 gearbox. It was an early car, with a tail-shifter. Not sure if he had to swap much stuff in from the 914 box, or if he just monkeyed the linkage, or what. But re-setting the ring and pinion is a non-trivial endeavor, so you might come out ahead only tearing the gearbox "halfway" apart.

From what Ive heard, the early 911 trannies were 901 with the ring gear flipped. I had a friend show me the prcess of flipping the differential with an open tranny and it seemed really simple.

The un-simple part is verifying that the lash between the ring and pinion is correct.

Well the latest info I have found on this is that the corvair engine can be boared out to a 3.3L and over 200hp for around $1500. This includes doing the case, new pistons and all of that stuff, and doing the heads. One I saw on a dune buggy was a 2.6L and dynoed at 240hp. I am still trying to track down the local dude with the 911 fan set up on the engine. The used engines them selves cost as much as a used TIV. I'll update when I get more.

I just finished doing a complete rebuild on my 61 corvair and it cost me around $800. That's including main bearings, seal kit and new pistons/cylinders rebuilt heads... They are extremely reliable motors too. I see all over the web of people putting them in airplanes. You dont take a risk in the air with motors that havent proven themselves reliable on the ground. The belt issue is their downside but if you go 911 cooling, you're done worrying about that. My motor is rated at 98hp but I think that the hp standards have changed since the 60's. Anyone know what that would be today? It feels like it has alot more than 98hp that's for sure.

By the way, they only made 2.7 liter motors and up. Where they varied was in the combustion chambers and stroke. The early motors (60-63) had a shorter throw. They then added a turbocharger and different heads for 180hp.(63-64) I believe the 140hp version (64-66)was a 2.8 with 4 carbs but dont quote me on that...They really haul ass and beat the hell out of buying a comparable hp porsche motor. At least in cost anyway.

Actually Corvair motors are available in two sizes stock. 2.4L and 2.7L. Between '63 and '64 they changed from 145 cu.in to 164 cu.in. Available in '62 the Monzas could be had with a turbocharger pushing out 150hp. This went up in '65 with the Corsas to 180hp. Some Yenko cars put out around 240hp and would spank a Camaro like no tomorrow.

I recently had the opportunity to work on a '62 Monza Spyder with the turbo 150hp engine. Since there was essentially no blow-off valve, all boost went right into the engine. This was regulated by only allowing around 6psi of boost to be generated anyway with 8:1 compression (down from the nearly 9:1 on the N/A motors). Plus it had a single Rochester one-barrel side draft carb. Whoa boy. Modernize that, throw on an adjustable waste-gate and blow-off valve, big carbs or EFI, and you could realistically achieve much more power cheaply.

Later,

G

The SCCA Corvair racers that I've seen all used triple throat Webers. 40 or 46 mm I'm not sure. I think you have to have the stock intake manifolds cut off since they are cast with the heads. Is this correct?

The latest info

I have found tha tthe local guy I keep referring to (still dont have a name) sells a 911 cooling kit for the corvair motor. The kit includes the shroud, mounting brackets for the fan and the alternator (custom), a 911 45 amp(?) alternator, 11 blade 911 fan, and belt for $1200. He also has custom bulilt heads that fit the webber tripple stacks for $2000 -$1500 pair with a set of throttle bodies, fuel injectors, and a TPS attached. I called Kennedy engineered products as well, and they have the adapter kit with flywheel for $440 + 20 for the starter adapter if you dont reverse the engine. The aformentioned cooling shroud kit fan only works with the reversed so the 914 starter is just fine. Of course KEP has some upgraded kits. The guy I talked to said that after you place all his stuff on a 65 of later 140 or bigger engine, with the tripple webbers, you will have 225 horse anytime you want it I have found a place called corvairpitstop.com in NY that sells engines for $100-500. I have yet to talk with someone there about the condition, whats included, etc. Basically what you are looking at, with a healthy estimate, is about $5000 for a 225hp corvair set up. Im guessing on the high to middle end. I intend to make a mega squirt FI system if I do this, and maybe even therer full FI/Ignition setup, but thats another thread.
