Porsche Speedster with 2.7L Corvair Turbo

Regrettably decided to sell my CMC speedster.  This is a one-of-a-kind 1957 Porsche Speedster with a 1966 Chevy Corvair 2.7L turbo that generates 165hp.  I've seen plenty of speedsters with VW, Subi, and Audi transplants, but never another one with a Corvair engine.  The car runs, stops, turns  as it should, with zero issues.  Car comes with a Clear CA title as a 0000 SPCN built in 1993 (more about this later).  The car sits on a VW Pan.  Looking on thesamba.com, the pan/chassis matches March 1970 (110272XXXX).  **** The title is in my name, however I have not been able to successfully register it on the California roads, hence the low price....***** The car would be an ideal option for someone out of state or who wants to track the car. 

Car was purchased from Rancho Santa Fe motors with a VW motor, but the previous owner didn't think it was enough HP.  He spent over $10K at Eurotech motors in Campbell, CA to replace the VW engine with this Corvair monster.  I have all documentation of the work performed.  The engine is matched with a 4 speed VW gear box and a quaife differential.  The speedster sits on its performance Motegi racing wheels (aka Traklite 2), Wilwood  disk brakes all around and brand new Michelin Sport Pilot wheels.  Brand new brake pads in the front, and the rears are at about 75%.  The car gets tons of attention wherever you go with it, and people are always scratching their heads when they look under the bonnet.

Interior is Raven Black in suede (doors, dash, doors panels, shift and brake boots) and real carbon fiber (including dash panel) which creates a beautiful color combination with the Red exterior. Detachable Momo suede steering wheel with working horn. Check out all the pictures to see the sides of the doors. All upholstery was done all brand new.  Seats are replica porsche GT3-RS in alcantera and carbon fiber accents, which match the interior of the car perfectly.  I cut down the headrests as they were way too high and didn't match the lines of the car.  Has all new black racing gauges made by Classic instruments in an aviation theme.  All gauges and lights work perfect.

Fitted with performance built 2.7L corvair turbo engine with single barrel stock turbo carburetor. This thing is quick, and the supertrap exhaust sounds awesome, 4 speed transmission. Has exterior oil-cooler running to the front of the car (so you can even drive it in very hot climates, like the desert, etc). Has front/rear disk brakes, new battery, great sounding performance exhaust system.  Custom Sony Stereo with handsfree bluetooth phone and music streaming.

I'll be more than happy to talk to you about the registration hassles I encountered and provide documentation

Vlad,

If you are serious about selling your car, I suggest that you complete the registration process.  Trying to sell a replica without a current registration is extremely difficult, as it should be.  An interested buyer is not likely to be convinced that the "paperwork got hung up at DMV investigations".  I'm not suggesting any impropriety, but it's a major factor for a potential buyer.

I like the installation of the Corvair engine, reminds me of the custom dune buggy that Steve McQueen had in the Thomas Crown Affair. I believe the Turbo version of the Corsa for 1965 and 1966 was 180 hp,  I'm pretty sure of that.

I am an old Corvair  owner from way back and had many turbo Corvair cars. You can really improve the power on that engine from the stock condition . We have found the actual HP of that engine with the one barrel Carter YH carb is probably in the 110 HP range. The 150HP numbers they offered up back in the 60's were pre SAE numbers and inflated because the dyno run was made without the alternator or cooling fan hooked up or a muffler installed. The way to really get that engine to go is replacing the stock carb with a Weber 45 DCOE dual throat side draft carb and a modified exhaust housing to bring the boost up. That engine was under carb'ed as a way to limit the boost. The exhaust housing to turbine clearance was way loose also, this made for a situation to have boost only come up in a high load situation. Reminds me of the modern Ford eco-boost system on some F150 trucks.

 I had an engine putting out an actual 250HP at 20 lbs of boost and it was daily driver reliable.  The engine was in a 73 Porsche 914. Word of caution, the corvair engines are not cheap to work on.. maybe more than the VW engines if you want to go fast. I think there is still some guys in California hot rodding these engines for sand rails. Again to me it is like knocking my head against the wall because it feels so good when I stop. Using 50 year old tech. when modern technology is available for the same or less giving me more makes sense. Maybe because I've been there and did that already. To each his own I say.

Is the Corvair engine reverse rotation or is the ring and pinion flipped in the transaxle? I have done it both ways and they both have their downside. Building the engine to run in reverse makes the issue of keeping the cooling fan belt tracking correctly. If you drive these for 5 min. with a thrown belt you will over heat the engine to destruction. The ring and pinion flip was my favorite but makes for a weaker trans axle. vw vair backvw vair engine

OK, so I was able to register the car and have been enjoying it for several months.   I added fog lights, LED headlights, and put better hood strap chrome ends on, see updates below.  The paint is still shiny red, although looks dull in the pics.  I ended up taking the headlight grills off and selling them since I didn't quite like the look.  The car is registered as a 00 SPCN built in 1993, so there may still be a requirement to get it smogged.  Since Corvair didn't have smog equipment back in 1960's, this may be an issue in California.  I had a BAR inspection done when I was trying to register it under SB100, so the DMV worker mistaked it for a Smog certificate (at least that is what I think), so the car is good for the next 8 months; after that there may be a problem smogging it.

New asking price is $26,500.  Price will go up in the summer
