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) |

3.0L
The Aluminum case of the 3.0L won't kill your whole project budget at the machine shop, the mag case of a 2.7L might. Jim |

Jim (IMG:style_emoticons/default/agree.gif) without a doubt. I am doing a 2.7 because I got a screaming good deal on it (Thanks again, Thomas - Tschrifield). If you don't already have case-savers for your head studs, they are a must and will set you back hundreds that you wouldn't have to spend on an aluminum case. I would also rather have an aluminum case for longevity and strength. The good thing about 2.7s is that cores tend to be cheaper, so this may offset your machining costs. If you aren't shooting for 250 hp, I wouldn't rule them out if you find a good deal. |

I'm really not aiming for mega-horsepower. Anywhere near 200HP will be fine for this street car. That's quite an upgrade anyway from the stock 2.0L. |
