I was just surfing eBay looking at engine prices.

PMS is at 30k for a 3.6
That is nuts.
10k for a core 3.2, again, nuts.

Then I found this.

Adapters would be the big cost on this conversion. Probably everything would have to be custom made.

and does it fit?

If Marty can fit one so can you...

..... and the ancillaries it needs will up the price as well (turbo, piping, electronics, exhaust, cooling, fuel, transaxle, etc. If the engine is in good condition, could be a fairly economical start.

A 3.2 can be a weekend install. The turbo cayenne motor, not so much.

Meh, cayenne motor, boxster transmission
