rebuild specs for 914-6????

[murphys]

Buying a complete 914-6 from shop where it was in for work. Engine is out, and was going to be overhauled. What is the consensus for taking it out to 2.2 or more? Besides Carrera chain tensioners any other upgrades to do at this point?
Thank you and Happy new Year!

What do you want from the car? What is your budget? How concerned are you with originality?

The original 914-6es are pretty uncommon--less than 2500 of them were made if I recall correctly. It is worth at least considering keeping everything original, because they aren't going to become any more common. And a lot of them have been "upgraded" or converted to race cars of various kinds.

If you decide that originality isn't your thing, you can rebuild the engine up to 2.2 S spec relatively easily. There is something that prevents you from going much larger on the stock crankcase, I believe, but I don't recall what it is.

If you want a lot more torque and relatively nice street manners, you might consider locating a used 3.0 or 3.2 motor. The 901-based stock transmission can hold up to a 3.0 reasonably well if it is not abused, but it seems to be a bit marginal for the 3.2s.

Any rebuild of a 911 motor is going to be expensive. Figure $6K for a minimal one, and go up from there.... (Could easily be more if labor rates are high in your area.)

Car is original and not thinking of putting biggest 6 that fits. I just recalled that Porsche was using 2.2's in their 911's and also detuned to "T" specs for the 914. I would rather rebuild existing engine, than put something else in and have to store "the original engine" for eventual resale. Sounds like a 2.2 is the way to go then. Thanks

Nothing wrong with a 2.2 or bigger on a stock block 914/6 engine. Not that anyone can tell w/o a tear down. In most cases an engine that old will need new pistons and cylinders.....go for it.

Don't forget to update the distributor to a Bosch unit if it hasn't already been done.

Someone had told me about 2.7 cylinders and pistons with stock crank yielding a "hybrid" 2.5 type engine. What type of case work needs to be done to accomodate a longer stroke?

Where are you located? Mine has a 2.4S spec motor in it and it rips. It was built by the magicians at TLG. If you in California, you're more than welcome to take it for a sampling ride.
