Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

So here's the plan 1. buy a rusted out Chevy corvair and strip the shell off the frame 2. buy a wreaked Porsche cayman / boxster with the 2.7 flat 6 3. separate the shell of the Porsche from its frame 4. make the cayman / boxster longer because its about a foot shorter than the corvair 5. after some cleaning up, put the shell of the corvair on the boxster/cayman body 6. make it have between 300-350 horse since it will be light weight 7. hopefully the cayman / boxster has a manual stock but if it doesn't then I'll buy and put tin a 5/6 speed manual for fun factor (although if the cayman / boxster comes in an automatic when I buy it it might not be the easiest thing putting a manual in) 8. it goes zooom thoughts?

POST 2Original post

Would the end result be a mid engine car, like the Porsche , or rear engine? A quick glance at dimensions shows the Cayman is only about 8" shorter than the 2nd gen Corvair, and weighs about 300lbs more. I enjoy driving my '67 with the 110hp engine, but would certainly enjoy something with 3 times the power!

POST 3Original post

I gotta say it sounds like a technical nightmare and not worth all the headaches. Any modern Porsche 's electronics and wiring harnesses, including ECU/ DME , are tightly integrated. Much of the components are CANBUS controlled Aren't Corvairs air cooled? So you'd need to fit radiators ( 2 or 3), fans, and coolant lines to/from the front and figure where to mount them and modify the grill. That's all just off the top of my head.

POST 4Original post

Probably should have cleared this up but im using as much of the Porsche components that I can including the engine so its a Porsche powered. And since its Chevys first (and only) rear engined car it all works out. But it still is going to be a bad time for me since its a newer vehicle vs a car from the 60s

POST 5Original post

Yes I'm not clear on which components come from which donner. Hard to wrap my mind around it. Keep in mind finding a wrecked 987 with a good engine won't be all that cheap. There's a lot of cheap rollers out there with shot engines. So used engines are somewhat in demand.

POST 6Original post

well if they are that much more expensive with a running engine and a stable frame then I could buy a stable frame with shot engine and then buy a 2.7 flat 6 from somewhere for a decent price and then put the engine in the Porsche for (possibly) a cheaper way to do it.

POST 7Original post

well I would like to keep it rear engine like the corvair and that might mean more adjustments because the 987.1 cayman is mid engine not rear engine so that might cause some problems with where the engine would go

POST 9Original post

that will be the biggest issue but with a welder and a grinder anything's possible.
