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)

If you don't already have Wayne Dempsey's 911 rebuilding book, you should get a copy. Lots of great information in there about engine combinations that work and their resulting characteristics. And Bruce Anderson's 911 Performance Handbook is like drinking from a fire hose.

I am also shooting for somewhere around 200 hp. My current plan is to ditch the CIS, 9.5:1 JE pistons, S (ish) Crane cams (another deal from Thomas), and probably Megasquirt for induction.

I got very lucky with my motor. When I tore it apart, it appears to have a pretty fresh rebuild, and it already had Nicasil cylinders (can still see the factory cross-hatching!!!) and case savers or time-serts (can't tell which). I could probably clean it up and put it back together without even replacing the bearings, but I want to build a nice tight engine.

If you aren't in a hurry, do the research to help you decide what you want to end up with, and then just wait/watch for good deals on the components that will get you there. Best of luck!
