Rebuild a 2.7L or 3.0L six motor, which is cheaper? Options

[boxsterfan]

Which /6 motor is cheaper to rebuild? 2.7L or the 3.0L?

1. Assume core motor is in good condtion and no crazy findings when you tear it down.
2. Assume you are building the motor for longevity
3. You are putting this in a 914/6 conversion (was /4)

Unless you have horseshoes up your ass, you're not likely to be finding any 3.2 for $5-6K these days.

Yep!!
LA Dismantlers gets $8k-$10k for a 3.2 depending on mileage.

Headstuds worry me on a used 3.2, that's why I choose to rebuild my 3.0. But if you didnt have a motor, purchasing a 3.2, replacing the headstuds, valvejob and re-sealing the topend is not a bad route to go. Shouldn't cost too much for the top-end rebuild.

I've never heard of a head stud problem with a 3.2. There are rare cases of valve guides and rod bolt problems. My motor has at least 150k miles on it and it's never been opened. Still has good compression, doesn't smoke or leak.
Interesting... I just googled it and broken head studs are showing up on high mileage 3.2 motors. Ah well... Nothing lasts forever except maybe the earth and sky!! lol

Head studs are a common issue on the high milage 3.0-3.2, but unlike the mag cases that pull the stud out of the case, the dilvalar (sp?) studs are known to just snap.
Good news is it is most times an easy fix during a top end job.
3.0 have stronger rods, the 3.2 has been known on occasion to throw a rod.
Valve guides are not rare what so ever and must be serviced/replaced during a top end service.

The 3.2 is a real good engine and has a excellent FI system, but never be sucked into the complacency of thinking it's a perfect, bullet proof engine.
All versions of the /6 engines have strengths and weaknesses.

We were putting a 3.2 on an engine stand one day and a head stud snapped and it shot up 2 feet and fell on the floor. No one had touched the stud and none of the others had broken. It was getting a rebuild anyway but still....

We just rebuilt a 3.6, 2 days ago with 4 broken head studs.
