want to do with a 912 chassic
 

car is 1967 912 straight body needs paint and put back together.
I have two choices, put original engine back number matching and restore the car to original.
or put 911sc drive train and make it outlaw.
I have both engine on hand, so cost of engine is not issues, however, which way the 912 will have better value in the end.
let's say I plan to keep the car for 5 years and might sell it after that,

please advice, thanks.

Original numbers matching. No doubt. 912s are on their way up.

You could do both. Build a hot rod but in a way that it could be easily returned to the original 912 if need be.

To install a 911 engine requires cutting out the 912 mounts and welding in the 911 engine mounts. Returnable? Yes. Easily returned? Not really.

Also, one needs to deal with the clutch/flywheel issues of mating a 3.0l engine to the 901 gearbox. And then strength of the gearbox also becomes an issue.

I forgot to say, I have complete 911sc drive train, include 915 tranny,
thanks for advice, would love to hear more from you.
another idea, built original 912 engine for more power?

Its not cheap to build a hipo 912 motor - $8K these days?. John Benton can make one for you (Benton Performance) but if you want the higher power at a lower price point and still maintain the nice balance a 912 possesses then a Jake Raby Type 4 VW motor is apparently the ticket.

912s are fetching very good money these days and much more than a bastard 912/911 hybrid will ever fetch. As someone mentioned, you need to weld in the rear engine mount brackets which will need to be removed should you want to go back to stock.

915 installation in a SWB pretty much takes you way out of the realm of easily reversible. And are expensive modifications that will never be recovered on resale.

If you want a hot rod, my suggestion is sell the 912 as a numbers matching car, and find yourself an orphan 911 with no engine or gearbox, preferably '72 or newer. Then install your 3.0 and 915.

The oïl tank you have cut panel and is most difficult to returne back. Like Matt sell the car and buy 911.

If it were me, I would rebuild original engine with big bore kit. Its a 912, not supposed to be fast. But with the big bore you can run with any 2.0 or 2.2T.

Hi Matt:
is there any reason 72 or newer is preferred?

Yes, '72 was first year of the 915. It doesn't require modifying the tunnel to install the gearbox.

You'll notice I'm advising contrary to my own garage. I've got a '67 912. I love SWB and it's so light it is plenty "fast". Only thing lacking is a close ratio 5 Spd 901. Mine is still 4spd.

But it is also not my only air cooled Porsche. If I had just one it would be a hopped lwb 911.

Uhhhhh, how about a phenomenon known as personal preference? Some people like 912s for what they are and do not give a flying **** about it being a lesser-than-911 automobile.

Kind of like asking why anyone would buy a 911 as opposed to a 911 Turbo/930 when the Turbo will stomp the living **** out of a non-turbo 911 . . . :)

Personally, I would not buy a 912 or a non-turbo 911, but I think they are both cool & worthy car models in their own right (even though I poke MUCH fun at 911 Targas and 912s - right Christian? :D).

Lesser what? Depends on your metric. Power? 911. Looks? Tie. Gas mileage? 912! Handling? 912! Looks like the 912 wins!

Put it back together. Original 912 are fairly rare and getting scarcer as they are still being sacrificed for the crazy priced SWB 911's.
In equal condition 912's or worth as much or more than average 911's made after 1973.
So if you want a 911 hot rod you will be money ahead to sell your 912 as a 912 and buy the SC hot rod.

Solidified troll status.

The 912 is a different car - not lesser than the 911. Balanced, fun, charming in it's own right. The SWB 912 market is picking up steam in a big way. To modify one (especially with difficult/expensive to revert mods) would be hurting yourself on both of those fronts.
I vote to either put back to stock (or hot rod the stock engine, suspension, etc) or sell/trade for a 911 if you have to have a 6.

Judging by your list, your metric is price?
I have a different metric.
Who is right?
We both are!
How about a 356? 914-6?
A 356 is the slowest, but IMO I would put it above a turbo.
On the track, a 914 will run circles around a 912, likewise a 914-6 over a 911.
But around town, I actually prefer to drive a 914 over a 911 and definitely over a turbo.
To ME stying and profiling is more important than power.
I am in no hurry. The slower I go, the more people see me. :D

Don't feed the troll.

Pmax, I have a 1978 930 and a 1968 911S and am in negotiations on a 1966 912, those are my three favorites.
Like I said earlier, 912's are not cheap and are more expensive than most all mid year 911's and most SC and Carrera's in like condition. So no one is buying them to save money over the 73 and later 911's. You are kind of lost in the past and have not caught up with the current times.

Your naive comments and somewhat shallow opinions on the subject matter makes you sound a little troll like now.

OP was on 912 Porsche project and what to do with it.
People who are up to date on Porsche Prices know that 912 out value 1974 and later 911's on average and chimed in to that effect
People who have driving both know why that is.
You are seeming to not understand those basic facts. Which would be OK except you have argued against today's market reality. You are not arguing against just the posters on this threads opinion but the whole markets opinion. Which you seem to be out of touch with.
Lumping 911's together, S, E, T, Normal, SC, Carrera is really displaying your ignorance. Those are so completely different cars, worth completely different amounts.
so to say "911 is this" without specifying which one is showing a simple understanding of these cars.
