74/75 2.7 engine value?
 

I have a 75 911 and have stumbled across a 74 or 75 (according to the owner) 2.7 thst has been sitting in a garage for 15 years or so. What would this engine be worth knowing no real history on it? It is complete and has the CIS on it. I am wanting to pick the engine up and rebuild it and have a back up incase my engine bites the dust. What would this enfine be worth on the open market in its current condition? $4k? $5k? I have scanned the for sale section looking to see what the ask is on these ensigns- just don't see many for sale. Thanks for any info.

The reason you don't see many for sale is a lot of people have put them in the corner of their garages hoping to see the day that original 2.7 CIS engines will go up in value and be needed by people who are restoring mid-years.

Complete, running 2.7s with history and leakdown go for $3.5K to $5K. Your engine would be a core at best. The old CIS is probably worth $300, the fan $500, and the rest of the components $400 (oil cooler, etc), and the unknown block probably $1K, so that puts you at $2200. I wouldn't pay more for it. But that's me.

Thanks for the breakdown. I came across it and didn't want to get burned if I made an offer on it.

for sure if you don't, you are not getting any either.

Truthfully most people just don't like the magnesium cases that require so much work to 'get right'. Even a lot of mechanics wont mess with them, I am finding.

I have one. Case number matches my chassis number. I've been told this will help with resale . I don't know how much , though. Not many 1975 911S 50-state cars get a total concourse restore, do they?

I will run this one if I can get it going cheap until I can afford a different motor, I think. Then i will crate this motor and put it aside so I can say I have the matching motor if or when I sell the car.

My recently acquired 74 has a 3.2 in it. It was a selling point for me. I love me a numbers matching car but I wanted something to flog.

Itd take as much money to rebuild the 2.7 and add power adders to it as it would to buy a used running 3.+ and add power adders to it, I think. And I'd get more power out of the 3.+ too. Heavy sigh. Still in save mode....

Even with the market is crazy as it is...it still makes no sense to spend $20K to get a 2.7 CORRECTLY rebuilt.

There you go.

Everything is a core unless you have paperwork and actual numbers of specific tests that require very little special tooling. Everything is a core that's sitting in someones garage or storage unit, and the story of 'it was rebuilt before removed' is well, BS.

Every core to me is worth less than $2K. And the market shows this as well. A longblock 2.7 is still an anchor UNLESS it's got verifiable history. Especially a 2.7 CIS. Even now.

Yeah well when you go shopping for a motor you'll have a hard time finding one for less than $2k. Something that RUNS is going to be $2500 or so for a 2.7 and $6500 or more for a 3.0 at LEAST.

wishful thinking at least, please show me where we can buy a good 2.7 liter engine for $ 2500? with the dreadful hot running smog stuff removed, its a marvelous light miracle engine designed by Porsche before the EPA/DOT nonsense laws, its a non issue today, oh do not forget the paltry 85 miles speedo.

I doubt there's a complete 2.7 core to be found anywhere for less than $3 - 3.5K. Longblock core around $2.5K.

Only a few years ago, these were boat anchors, but everything 911 has just gotten stupid pricey.

See Ping - $2500 on a long block. I could link to myriad sales of 2.7s in the For Sale section as of late but don't have the time. There have still been a lot of 2.7 motors and blocks going from $2k to $4500. I look all the time as to maybe get a spare now that runs and has some history. I don't think they will get cheaper, but who knows?

I agree they are all cores unless they have recent history of running. But values will vary. A never rebuilt core is a $2000-2500 engine. One that has been rebuilt with case inserts and align boring, etc etc is worth twice that.
