Modified 2.7L value?

[smiles11]

If you had the same two examples. 73S with all stock 2.4L & another 73S with a modified 2.7L. Both matching numbers. Would it be safe to assume the 2.7L would be more or less valuable?

[mepstein]

Less. Unless the 2.7 is something really special, stock numbers matching wins.

[RSTarga]

Do both have MFI? What mods were done to the 2.7?

[smiles11]

Both MFI. The 2.7 modified by Seinfeld shop Scott’s Independent.

Read from the bottom up...

[EC900]

My opinion…2.7 slight value disadvantage base on past auctions. Bad engine, not necessarily so, just bad EPA consequences. Depends too how recently modified the 2.7L MidYear is. Lots of upgrades and if you have to live w/a 2.7 we might as well find a way to make the best of this black-balled engine. Both magnesium cases 2.4 vs the 2.7 but without a history on a 2.7 MidYear may have heat related (unseen) warping and seal issues as I have found. Modified to back date to PMO, SSI’s etc., all for show or a purpose might sway some to spend $$$ but w/o low end to compliment a new top end on the dreaded 2.7 curse case can be a no-brainer. Cool to be fast and pack some punch but it’s not for me.
Bottom line - Original as possible is always preferred. I’d be tempted to forgo rebuilding a dead 2.7 in favor of a well tended used MFI 2.4 (for weekend touring). Now a 3.0 vs 2.4 vs 2.7 ….

Depends if you are the q-tip, concours, PCA type (matching #’s) or the modified, canyon carving, driver’s quality type.

Me. I’d pay tons extra for the 2.7 from Scott’s independent as long as it’s got the mfi goodies.

Sorry this is not a mid-year car. There were no heat issues(or smog compliance) on the 73, the 73S 2.4 is identical bottom end to the 73RS, and same heads. Only difference are 2.7 RS pistons with Nikasil cylinders which are much better than the Alusils on the 2.4. Recalibration of the 2.4 MFI pump is required also.
No external differences at all! Just way more torque and more HP. A very sweet setup as long as the engine block mods to strengthen the Mag block.
It looks like the shop knew what they were doing and did a nice job. I did the exact same upgrade to my 73S 30 years ago and have been very happy with the improvement.
I don't think the value would be affected much if the numbers matching block was used.

[smiles11]

What if I told you all the buyer wants $250k for the car? Seems like 911s coupe money.

[RSTarga]

I’d say that is probably close to what he has in it.
That is a VERY nicely done car. A very fun car too.

[TKO]

A motor build by Scott's Independent is a HUGE plus!

[IROC]

2.7s suffer now from years (decades?) of perceptions that taint it as an inferior engine. If you go back read the magazine press at the time (1974 or so), the 2.7 was welcomed as an improvement over the 2.4. Valve guide material and ill-fated decisions to deal with the head stud/case issues doomed it in the court of public opinion, but in reality it was a good engine. The original 2.7 in my car was rebuilt at about 70k miles due to worn valve guides. Fortunately for me, they did not use Dilivar studs and I thrashed that engine for a full decade of track use before swapping in a 3.2. It was an awesome engine with no disappointments.

'Numbers matching' and 'period correct' means a lot these days when it comes to "value", but I would not shy away from a nice 2.7 from a pure performance standpoint.

My 2 pfennigs.

[Matt Monson]

I’d take the car worked on by Scott’s any day over the stock one. And here’s the thing about building a 2.7 on the stock 2.4 case… it’s invisible. Unless the seller tells you, you would never know unless you got deep into the throttle.

Edit: I’ll also add that the LSD mentioned on that list during the gearbox service is one of mine. Scott only uses the best parts.

The factory always thought the Targa was worth more

I don't understand the Targa hate crowd. All the open cars of any other brand, and even 356 models are more highly prized than in the 911 series.
In the real world of weekend jaunts, etc. Targas are more enjoyable.
Take the top off and listen to that sweet 2.7 exhaust bouncing off a mountain pass or through a tunnel.
Priceless, as Mastercard says.

[smiles11]

It’s not so much the price they’re asking, but what I’ve compared it with that is available. I’ve found more original 2.4L 911S coupe cars that are at or below $250k. So it seems the big sell on this car is that it was a Scott’s Independent built engine.

It’s very simple really. If you want a stock car, buy a stock car. Go click around BaT a little bit. Hot rodded cars built by the right people to the right spec, are selling for more than stock cars. The car you are considering is basically a Carrera RS spec vehicle for S money. Good luck getting an actual RS for twice the price of this car.

[RSTarga]

First drive one of the stock 2.4S, then drive this one. I guarantee you will have a smile on your face.
It looks like someone took great care with this car, someone who knew what they were doing.
Please post more pictures!

[smiles11]

Im in the process of acquiring it today. I’ll post more pics soon 👍🏻

Thanks everyone for the feedback
