was considering a 2.7-ish engine for a shell that I have. After reviewing what is necessary, I am starting to think that a big four is sufficient.
what is the normal power output for a 2056, and can that setup run on FI? looking for something with a bit more power than what we have. Currently have a spare 2.0 out of a '75/'76 sitting in the garage... thanks! -JON |

I have been debating the exact same thing. Based on power, weight and cost I am leaning towards a big 4. Here is what I have been tossing around:
2.4 or a 2.7 will have lots of miles on it and your looking in the neighborhood of 3000-3500 for a half way descent one. Oil tank if you go with a tank like the one from Patrick motorsports your looking @ 500 for a front tank or 1000 for one that bolts into a stock six location. mounts, exhaust, etc... so before you consider any kind of refresh of the 6 your already out like 6K ish... I was adding up what I could build a wicked dry sump type IV and if I do the work myself I think I could put together a ~200 Hp (@ the crank) engine for around 4500 - 5K and have a brand new engine ready to rock and roll. If you look at rebuilding a porsche 6 you can go north of 10K if you buy new pistons and cylinders(2500), have the crank done at ernesto's (500), Case done at ollies (1K), ARP rod bolts (300) or carillo rods 2700... then head work the sky can be the limit... My friend has been putting together an RS spec 2.7 and he has a spread sheet of all of the costs. he is @ 10.2K and he wil be putting it together himself. I think the 10.2 included a set of webbers with rebuild kits and pmo intakes too though. I know that was kind of all over the place with this but I am pretty sure you see where I am going with it. I think 5K could build you a wicked type IV or 6500 you could have a tired old six that will probably need to be rebuilt in a matter of a few years and not really a track worthy engine. Plus the six is about 200 pounds heavier if I remember correctly. |
