Whichever option you decide on the "downside" is the expense....however, with a rebuilt or "fresh" motor, you essentially have a "new" vehicle with 0 miles on the odometer.........and since resale is of less importance than reliability, your "long term" prospects would be excellent.............just sayin'I joined the forum to get some feedback on a project I am considering, this seems like the right place to ask.
I have the opportunity (or nightmare) of bringing back to life a 2006 Cayman S. The car has a spun rod bearing, I plan to bring it back to life as a street car with 4-6 track days and 5-10 auto x days a year.
Looking at a few options I'd like to see if I have my facts right:
1. Swap in a stock used 987.1 motor. These seem to be going for 9k+ for well sorted examples on ebay, I am again taking on the risk of running into a similar issue as these motors don't seem to hold up very well. This is also the cheapest option.
2. Swap in a stock 987.2 motor, on paper this should be lower mileage, however more expensive, and it doesn't seem like a straight forward swap. At least not from the info I was able to find.
3. Swap in a LS motor, this is the most intrusive and most expensive, but all things considered between the motor and the renegade hybrids kit I'd be just over the cost a 987.1 motor and the rest of the cost (a few grand) will probably be spent on all the misc things that add up. This gives me the most power and potentially reliability with relatively cheap maintenance cost into the future.
I plan to keep the car so resale is of low importance, of high importance is reliability over the long term.
