I'm looking for an engine for my car. I'm considering a 2.7 /6 conversion. The 2.7, despite it's possible problems, looks like it would be far less expensive than a 3.0 or later /6.
Problem is, I know very little about them. I know that they are notorious for pulled head studs. I know that the tensioner upgrade and turbo cam covers are desirable. Worst case, what am I looking at if I purchase a core sight unseen? Is it scrap? How much does machine work typically cost to rebuild a 2.7? Time-serts? My other options are a 2270 or a Subie. The Subie kills any chance of competitive racing, but the reliability looks promising. The 2270 would be in the distant future, as I don't have the funds for a complete engine right now. I figure I could build a 2.7/6 over time and fund it as I go step by step. Might take years. Any advice on the 2.7 option? |

5K is really pretty conservative for the rebuild cost if you buy a cis 2.7 in unknown condition. A friend of mine is building one to RS spec and including the cost of the core engine has about 10K into his. Case work from ollies is about 1500, Crank work another 600, buy a set of webbers and a rebuild kit 1100, pmo manifolds for the 2.7 170 bucks, rebuild the rods with good bolts 500 bucks, new RS pistons and cylinders 2400 bucks if you can find them for that price.... on and on ...
However, I also think that a 3.2 / 3.6 conversion is a stretch for the 901 (personal opinion) All those things considered the 2270 is a lot cheaper option. Also dont forget that for the oil tank 1000, engine tin 400, and 914/6 headers (without heat) 500. I have contemplated the same things over and over so please read that as just sharing my research. I am leaning towards the 2270 due to the bang for the buck factor... but I am a flake so could wind up doing just about anything (IMG:style_emoticons/default/beerchug.gif) |

Also factor in the cost of the oil cooler (/6 or modified), oil lines, motor mount, clutch/PP/flywheel, muffler, fuel pump, CD box, /6 cables, /6 Tach ... staying 4 lug? |
