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)

I do agree it's not a cheap or easy task. There are several people that are mechanically inclined that have rebuilt their own motors on pelican. It's not easy but can be done. It's just the overhead cam's that create most of the complication, other than that its not too far off from a type 4. But I do agree it is a risk to build your own motor.

As far as pricing I think for the machine work +20% would be close, best to call your local machine shop to verify. P&C's can be rebuilt if you have nikasil's I bought a set from EBS for ~$2600. Crankshafts are rare and expensive, luckily you only need one if the old one was badly damaged. They are nitrided so they are very strong.

Another note it is another level of complexity to do the bottom end, I would be less worried to tackle just a top end rebuild than an entire rebuild. You can also do alot of the work yourself and have a shop assemble the bottom end for you. Top end is still complex, but you can take your time until you get it right.

Its also very labor intensive, like 80+hours. That I believe is part of the reason for the high rebuild costs.

Buy a core inspect it very well, add up the costs, if it ends up being too expensive just sell the parts off...
