3.2l Corvair Engine Build, preliminary ideas and questions Options

[macnichol]

As I've done more and more research on potential engine swaps for my car, I've come across some people swapping the Corvair flat 6 into their cars. I really like this option, as it keeps the aircooled spirit of these cars, engines are quite inexpensive to get to 200+hp compared to a conventional 911 Flat 6. These engines rotate backwards so I need to come up with probably a new way of reversing the rotation, since I quite like the 901 gearbox. I think for now I just want to aim for 200hp at the wheels, even though I know these engines are capable of much, much more. My plan is so far is to get a good example of an engine, swap in 94mm Mahles and 911 bits and stroke it a small amount to 3.2l. I think this will be a good balance between a few things, I want to stay away from boring stuff out in the interest of long term reliability. I plan on fabbing up a 911ish-style fan shroud as the stock cooling of the Corvair was not designed with our mid-engine setup in mind and I can foresee cooling issues, especially with a larger displacement engine. For those of you who build your own engines and maybe the king Mr. Raby himself, how reliable are aftermarket nikasil coatings and cryo treatments? I may build a few of these "hybrid" engines if there is enough interest in a powerful alternative to 911 and Raby engines, I feel like many people have been priced out of that market, not due to anyone's fault. I've done some digging over at the corvair forums, it's not uncommon for people to get ~300hp and 100k miles out of these motors before rebuild, as long as proper cooling is done and maintenance is looked after. What do you guys think?

Retire the cassette deck and enter the digital age.

A Subaru 6 with a Subaru trans is a way better combo, and practically bolt in these days.

Engine is 300 lbs loaded so weight is not an issue.

Factory EFI works great 100% of the time. A/C optional.

00's engine tech instead of 60's....

Parts.... parts everywhere.

In a 914 is one thing


. but both me and my neighbor think it's hilariously that subaru themselfs recommend new headgaskets ever 100k miles . $$$$$$$


While we drive our toyotas 200k and 300k
Miles doing only oil changes.
So for that reason alone i would never touch these subaru motors . i mean who wants to tear there engine down ever 100k miles . certainly no one that actually commutes to work and i think all wheel drive is a little overboard for the daily commute too . but i guess subaru is getting rich either way. I just dont see the engines as the greatest thing since slice bread . unless you need a opposed flat 4/6 which you really never do but ....

When they swap a toyota engine into a wrx . then maybe id be interested.
