Hi all,

For a few months now I've been working on installing a 2.8L 'reverse rotation' Corvair engine into my 75 1.8L 914.

The engine is notionally a 140HP engine, but has been modified - before my purchase of it - with a more interesting cam (Ott 30), triple zeniths 40 TINs (with throats bored to breath better) and a reverse rotation cam shaft so the engine goes spins the correct way to have 5 forward gears and one reverse, rather than vice versa). Have used original side shift gear shift rod and all clears in all gears

The engine is now all in, all fits with no body modifications required whatsoever.

I've driven it briefly, only in 1st and reverse, but with no exhaust system, which is now being made.

Here are a few photos taken in the last few days.

The flexible hose hanging in one of the photos is the cold air feed for the heat exchangers The heat exchangers will wrap around the secondaries - giving ample clearance for axle movement up and down.

More than happy to add additional photos or respond to any questions.

Cheers
Dave

It really is not that much to get, rebuild, modify, and install a corvair engine in a 914. I was doing this until a 2.7 Porsche motor dropped in my lap. I sold the first kit I had gathered and machined for a 3.1L using type IV p/c. Then, the bus idea came along (see the link in my signature). It runs and drives with the 4bbl, currently. I have the triple ported heads, but didn't see a need for Weber 3C carbs due to cost and the fact that it is a glorified mini van. In a 914, different story and I would go with all the hop ups. We have a significant amount of support in the states for corvairs and modifications. Look on ebay and search "vw corvair" and you will find all you need for pretty cheap. r3dplanet is building an impeccable corvair engine for his conversion. Makes mine look like dog ass. I didn't reverse my engine as I wanted an automatic trans for the mini van, kept the 2 speed power glide, rebuilt it and put Posi into it. I have had my bus over 100mph on a long, dark, straight, level freeway on the way to Canada for a clinic a few years ago. That was when I had the wrong roller rockers installed (sold under false advertising) that then broke off on a follow up trip to Scotty Bs shop. If anyone wants help with corvair stuff, I am here for ya. I like building them, they are pretty easy and cheap compared to our cars (IMG:style_emoticons/default/smile.gif)

Definitely interested in your heater idea. I think I will see about commissioning someone with stainless welding skills to make me a set. The bus has no heat and that is not doable for about 4mo out of the year.
