1981 911sc Targa with 2.4L 911t engine

[brooklynporsche]

Hello all
I'm a newbie and glad to be a new Porsche owner finally. I now own a 1981 911sc Targa. I recent purchase a fuel accumulator and distributor cap and rotor and notice they could fir but after further investigation the engine I have isn't a 3.0L 911sc engine I have a 1973 911t 2.4L with a Bursch muffler with no A/C compressor. My question is do I try getting rid of the engine or is this a blessing in disguise. Also does this change the valcue of my car. Thanks In Advance

Welcome, and congratulation on your new purchase!
First, your questions. If you truly have a 73 2.4t engine in the car, then your value is reduced by a significant amount IMO. Not only is it not proper for the car, but it is a smaller, less powerful engine that was built for a lighter car--the 73. You intended to buy an 81, and I'd suggest you try to replace with a 3.0 engine if you're willing. You will increase the value of the car and increase your driving experience as well.
BTW, the 2.4, if it is in good, solid condition, is not a dog. It is a reliable engine and if you choose to sell, there are early car enthusiasts who will be interested.
Keep us posted on your quest, and be sure to post pictures of you new find--it's required!

The engine # is stamped on the right side of the fan support, vertically. The numbers posted by Paul are samples of what you should see--the first three digits being the first major clue. If your engine is a 73 2.4t (U.S.), it should start with *613XXXX*.
Post your findings for further information.

Not sure how long you've owned the car, but can you go after the seller with some kind of legal action? Or return the car to the seller for 100% refund?

What else can you tell from these numbers.

i think the engine's a US 1973 911T engine with CIS its was originally matched with a 915/12 transmission

Whats different bewteen the US and Euro 911t. Aslo do you know what is the going price for the 911t.
Thanks

[red67]

the US was faster in 73 - it had a CIS injection system (140HP), the euro had carburetters (130HP).
i dont know the value but theres lots of more qualified guys here who will.

Price will be based on condition, naturally. A quick look on the for sale page shows a 73 2.4T engine (in running condition) ranging from $3-4.5K. These were asking prices from a very brief look, with the higher number for a fresh rebuild. You will need to asses the condition of your engine and the work that has been done, then do a little hunting in the for sale page on various sites. I'm sure people on this site who know engines as a profession will offer some guidelines.
