What to look for in buying a 2.0 six.

[SteveStromberg]

Thur the board I found a 2.0 911S motor just down the road. I am looking to Install it in a 70 914. What should I look for as problem areas in the 2.0. There are no carbs and the motor has 80k on it I was told. Can anyone supply me with a set of carbs? Any tips or suggestions would be appreciated. Steve

I would get a leak down test done... Also
check the serial numbers by the fan housings
and make sure they match the numbers that identify this motor as an S motor. I believe this motor orginally had MFI but should run OK with carbs. Ask this question on the 911 Board there are some guys that have lots of Experience with the early engines.
Good Luck

Buying a 911 motor is a trickey proposition unless:

If you can see and hear it run.

The seller has receipts from a reputable
shop and the motor has not been run.

The seller is your mother.

IMO, anything else is a core motor.

My reasoning is based on the expense of a rebuild. I would rather see a disassembled engine, rather than a long block, because all the stuff that breaks/wears (and there is a LOT of it) are inside and replacement parts are very expensive. My recent rebuild (DIY) of a 2.7L,which was basicly sound, was around $3500. I bought the long block for $500. The 2.0L is no less expensive, rebuildwise.

AFAIK, there are no 2.0L specific problem areas, other than the lack of oiling system upgrades, which can't be checked from the outside....Carrera tensioners show that the
seller did have his stuff together and is an outward, visible sign. As Joe said, a leakdown is not a bad idea, but the bottom end could still be toast. Many "top end" rebuilds are done with out spliting the cases....common, in fact.

An unknown long block is worth what you figure you can part it out for and even that is a bit of a gamble.
