New to Porsche...what to do?

[DCOP]

I have recently purchased a 1970 911T. It's a beautiful car which has been given the RS replica treatment. It has the 2.2 w/ webers which is starting to show it's age. It runs good but the last compression test was weak (120's) and it does smoke a little when cold.

I found a local P wrench who is obtaining a '70 E w/ MFI (90,000mi) and will be parting out. He said it hasn't run for 10 years and will call me when he picks it up and gets it running.

My questions are: Should I look into rebuilding my existing engine$$? If the E motor has good compression and leak down what is it worth? Will sitting for 10 years make it a risk? If I take the E motor should I convert the webers?...decisions...decisions.....

PS...This is a great BBS and I have learned a lot from you guys already!! Thanks!

IF you buy that E motor? Do all you can to keep the mechanical injection intact. You will not be sorry once it's working right..
and you won't believe the difference between E and T!

Darryl,

While your engine may very well be tired, I've just had my 2.7 MFI engine rebuilt -- completely -- and it smokes for about thirty seconds (hand throttle up all the way -- engine oscillating between 2-3,000rpm) when dead cold, i.e., after a night in the garage.

The smoke is a symptom of lubrication, not always wear, and is one reason why these engines last so long.

Without being sure about the details, what I have been told suggests your smoke is a sign of very sexy racing pistons, as much as anything else.

My tired-out 'T' only smokes the next morning if I have been driving it hard the night before on the way home and the oil is good and hot.

By the way Darryl, I have E cams on the T and the engine has a very nice powerband - it sure doesn't feel like 110hp, even though I can't be making the full 140hp of the E.

I'd sure think twice before buying an engine that had not been started for ten years

Darryl, 120's for the compression test is not a problem. They are low compression engines. It's the amount of variation between the cylingers that count. And like the other guys said don't worry about a bit of smoke on startup. Get a good tune up done and change the oil to a good 20-50 (Castrol GTX maybe).

Why don't you just enjoy the car for a few years and decide in that time what you want to do in the way of upgrades (if any). Hang onto your money for the time being.

Darryl:
I agree with Bill. Drive the car & enjoy it. In the meantime, keep your eye out for another engine. I don't think I would buy an engine that hasn't been run in ten years, unless you are going to have it rebuilt before you use it.

Just drive it! And build up an excellent tool cache and library of manuals, so you can do all of the maintance on it yourself. You will not regret it.
