Yes, an 80mm but it's spoken for, the wife's 914
cheapest way to fix a 996 or boxster engine is with a factory shortblock exchange, but then you still have to do the rest of the engine.
The 996/boxter flywheel you have to replace, the rubber center goes and causes misfire codes, add a clutch kit and there's a couple grand. Same with the coil packs, around $500 not replacing them is false economy.
Big issue is making sure the rads are clean, you have to take the front bumper cover off to see all the crap behind the AC condenser. I just replaced the rads in a 4S with a pair of CSF rads, beautiful units.
AOS, water pump, T-stat, starter Y cable...Nothing is cheap, the price creep is large with these cars. Just did a 4S, $5k quote for IMS, by the time all the "while you're in there" stuff was done $15K easy.
