Value of complete 2.4T engine?

Scooter · 12:41 PM

I am getting ready to replace my '72 2.4T with a 3.0. Question is, what is the 2.4 worth? I know they are somewhat popular as a core, to build up a high performance motor, due to the ability to customize the boring of the heads to your exact specs. But, my 2.4 is more than a just mere core...it actually runs strong now.

Here is the deal:

Engine = 1972 2.4T with unknown mileage
Carbs = Zenith carbs from the 1970
Heat Exchangers = early factory exchangers in good condition
Muffler = fairly new Dansk dual in/single out
Knowns = engine does leak some oil (they all do). A small drop overnight, after driven that day. It goes through approximately one quart per 800-1000 miles, depending on how you drive. It does have some blue smoke at start up if it has been sitting for a number of days, but goes away in short order. If you are really pushing it with high RPMs (5,700-6,000) then quickly decelerate (i.e., really driving the car like it should be driven), there will a little smoke as well. I am told that the smoke is nothing to be concerned about. At least not for quite some time.

I have had a couple well-known mechanics and other knowledgeable Pelicans drive the car; they all say the engine pulls very strong and there is no reason why it should not last for some time. I've been given an estimated price by my knowledgeable friends, but also want an honest opinion from you guys.

So what do you think? Price? Demand? Other comments?

Is it a 5R or 7R case? The 7R case is more desirable for a hot rod motor. Also the loss of the MFI effects the value too.

Thanks for the response Brian. It is a 7R case. I am aware of what the loss of the MFI entails. I am really just looking for an approximate value from an honest, disinterested source. Thanks.

It's not worth much as far as 911 engines go. As mentioned, the engine lost a lot of value with the MFI gone, and Zenith carbs. Maybe $2K? Anything above, it might sit. A T motor has iron cylinders, so they wouldn't be wanted by anyone unless they're rebuilding a T to T specs. The iron cylinders retain too much heat. The fact it pulls strong doesn't say too much. A friend of mine has a 3.0L that pulls real strong, and smokes a bit. He tore it down this winter to find some cracked rings, and worn crank bearings. I'd say part it out. You can sell it quicker that way, and probably for more money. People will want the 7R case. Maybe you can get $3K parted out, and you won't sit on it.

As a side note, all 911 engines don't leak oil...it sounds like you're trying too hard to sell it, and it will turn people off.

Just an outsider opinion. Good luck!

Thanks for the opinon Jay. I am not trying to sell the engine here, I was trying to represent the engine as honest as possible, in order to get an honest opinion. Although I may not agree with some of your opinion, I do appreciate your candor and taking time to respond.

Scott,

I am in the market for a complete 2.4 MFI T motor and was thinking I would have to pay around $3000 for one. It would not matter if it was running or not as it will be the basis for a hot rod motor. So if you back out the MFI but it is running then maybe $2000-2500 range?

Bump, and a question:
Were there actually 7R cases in '72?

Scooter · 03-06-2007, 10:27 PM

My understanding is that all 2.4 and 2.7 cases are 7R magnesium.

goldsc78258 · 03-07-2007, 02:58 AM

My understanding was that the only 2.4 7R engines where made towards the end, like on the 73 1/2 cars but I might be wrong

Scooter · 03-07-2007, 03:24 PM

My mistake, it is a 5R, which I believe is still desireable for the same reasons I stated above.

Guys,
My 2.4E motor (1972 engin code stamped) is a 7R case.
They made 7Rs in 1972.

My 2.4T block is not a 7R.

$2k doesn't sound bad at all i think. I sure hope i can find such a motor if i ever inadvertenly install a secondary oil release pasage in mine!

Bavaria, do you ever get to the Md. shore? I'd love to see your car and find out what a 2.4E w/ webers feels like. My '70T has a 2.4T block and supposedly 2.2S pistons along with some other goodies and is fed by 40 Webers.

Good running, complete 2.4 T motors are too rare to have a commodity price.

There is a range of value, but in my experience it's this:

You have one to sell -- $1500 is the market value.

You desperately need one -- $2800 is the market value.

At least that's the way that stuff works for me.
