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) |

a totally tight car with 115-125 hp would be plenty enjoyable and cost a shit load less. just saying. what is the status of your car at this moment?

Jim I think to OP is looking @ around 165 - 180 hp which ever motor he buys,again the cost to do this a 4 cyl is really up there cause you have to spend the extra to keep it reliable. The cost involved in making the 2.7 more reliable is well documented,the 5 blade fan motors had big case issues for example due to overheating. Both motors are rather lazy in there power output due to the CIS,many report good gains just going to well set-up carbs....then economy is an issue however. The 3.0 is my choice because they are very reliable,make sure you buy a motor that is the most you can pay and a proven runner to start with. You are going to spend a lot of money because its not just buying the motor ,but when you look at the original sixes now beyond any average guys budget the good conversions will hold and improve resale prices as time goes on. |
