What to do with 911T engine?

[snowman]

I have a fresh 911T engine and 5 speed. I have the following choices to put the engine in:

1. A 1965 912 all there, straight, project car

2. A 1966 912 race car

3. A 1969 912 daily driver thats been completely restored.

Which is the best car to put the engine in? It will then be a fake 911 but with real 911 parts.

The race car has a 200HP 912 engine in it
The 65 is less engine.
The 69 has a good 912 with big bore kit and a 4 speed.

What are the chances of getting $17k for the 912race engine? Has everything and a fresh dyno run could show current performance. Everything means Carillo rods, scat light weight crank, 12:1 forged Shasta pistons, 36mm Solexes, big valves, schmitt pwr pully, cam gear, custom cam, Ti retainers, big valves, everything ported and flow tested, and on ond on. Been racing for two 20 hour segments between teardowns, no rod or crank bearing wear to speak of (using Red line 30wt race oil). Has been dynoed at rear wheels at over 145hp on the ground at 7800 RPM. Red line at 8300 RPM, should withstand up to 10,000RPM on a missed shift (but ONLY with Red line oil).

Restore 912's to original? sell race engine and buy an engineless 911? Any and all ideas welcome.

PS I am not sure exactly where this should be posted so I chose what I am more comfortable with.

Zero.

BTW -- How does 145 RWHP translate to 200 crank HP? If that's true, you have some real transmission loss issues.

How much of a 912 fan are you? The reason that I ask is that I'd put the T-Engine into the '65 and you basically have a solid turn-key (but wholey non-authentic) 911 starter car for someone. Or you can sell the other cars and develop that car and have cash left over towards a race 911 or parts.

The question that I have is -- What do you want to do? Race in a higher HP Class? Start a new project? Expand from being a 912 afficianato to a full fledged 911 fanatic? One option that you didn't mention is sell all of the 912 stuff to a die hard 912 fan and buy a 911 for street/track/mixed use.

My only heartburn is that you just do not see that many early 911's and 912's. Putting a 911 engine in a 912 really hurts its value to many people.

If its not too much work (and I have switched a VW engine in an hour lots of time) I would pull the engine out of the 69 and put it in the 65 and keep it a 912. The "T" engine could then go in the 69 and be used without destroying the value of the 65 912...

Have owned 911's for years but still like the 912 and feel that it has a very important place in Porsche history. Someday will get rid of some cars and buy one!

Jack;
To elaborate on my engine comment a little more, here are some reference prices I've come up with after a couple of minutes looking:

1) A complete American Sedan Mustang with a "Pro Motor", etc. etc, spare body and motor parts -- $10K

2) Taber/Comptune FP dry sump 1275 complete motor. Motor is fresh with dyno sheets and has all the right parts. This is the motor Craig Chima broke the track record with doing 1.37s at Mid Ohio runoffs (chicane track). Includes matching Comptune carbs and intake, very low hour Tilton aluminum flywheel and 7.25" clutch and pressure plate, TDC dry sump pump, dry sump pulleys and Huffaker harmonic balancer set-up. This motor ready to go in your car everything included. Craig and other have stated this was the best 1275 to come from Tabor's shop, fresh and ready to go in your car.
$8500 Firm!

3) MAZDATRIX 12A E/P Street Port motor is for sale. Proven Winner and very strong!! Will have it available at the Runoffs. This motor set 2 track records and has 3 wins. Header, exhaust, and short intake will be available as well. $4,000 for motor. $4500 for whole package.

4) The classic cheap HP: ... as I'm sure you'd agree.

5) A complete 1999 BMW M3 Speed World Challenge race car: Asking $20K

6) Loyning Pro-injected spec FA motor dressed for a Swift .008 chassis: $10K

Admittedly, there aren't many really nice full-race 912/356 engines for sale, but unfortunately there aren't very many people looking for them either. If you can find the right buyer, you might get close to that. If you can't find that right buyer, or if they don't exist right now you'll get $5-$10K I'm guessing. Maybe.

I only use the 200 number because its what the dyno 2000 program predicts, and its possible using some typical drive train losses as well as the fact that I have a fully functional generator and fan going.

In any case, even if you use the lesser of the drive train losses you get over 170HP at the flywheel which is at the very top of what any 912 race engine can produce. 200 also sounds better.

As to value, you cannot get any 912 race engine with all these parts for less, unless its very worn. Just the parts gets it up to the $10k mark. But if there are no other fools like me willing to put togather the best 912 out there, I guess I will not get that much. But thats part of the question I asked, SO???


I have leaned toward putting the 911 engine into the 69, just because its the daily driver, but then again, I do not have a Real 65 engine for the 65, as to the 66 its a race car, meaning its not all original or even all there anymore, what to do? Also the 69 would require changing the axils to fit the earlier transaxil, not an inexpensive proposition.

I would put it in the 65 912.

If you put it in the race car, with a 911T engine it will no longer be a race car. 911T engines are not the fastest of things.

If you put it in the fully restored 912 you will devalue it.
