912 E into 911 --- TEMPORARY, will it work
 

I've decided to rebuild my 2.2S engine with webers as the intermediate shaft is out. I need a temporary engine while the 2.2 is being worked on as this is my daily driver. I've looked for a running temp 911 but have recently come across a CHEAP running 912E with webers.

Realizine this is the old 914 engine, will it fit right into my 1970 911 with the 901 tranny and other hardware??

I am sure someone here will know, but you might want to try over on the 912 board also. One thing I do know, is that the 912 motor mounts are located in a different place then the 912.

No it wont it uses a very different and very hard to get rear engine support bar. Also the input shaft on the transmission is completly different which would require a custom made clutch or the use of the 912e "type 923" tranny. Aside from the likelyhood of 5-10 other mismatched parts you will be dealing with a svelt 88 hp at the crank ! Basically you swap idea should be forgotten .

the drastic drop in hp for the short 3 months my S engine will be out for rebuild is something that I would normally have to live with. I'm just having a terrible time finding a temporary flat 6 for a resonable price knowing that in the end I'll just dispose of it. The $500 for a 912E engine is something I"m strongly considering as an interim fix....if it would work without a major amount of other rework.

If buying a tranny or custom built cluch as well as welding motor mount tabs foward of you existing one`s is not a problem for you then give it a shot. Forget it if you dont get the rear engine brace though. My opinion on this idea is run away fast. You will spend much more and get much less power. Also you will still only have a $500.00 engine when your done. Why not go tip your engine builder $500.00 as an incentive to hurry up. A full overhaul could easily be completed in 2-3 weeks . And with a nice tip like that you will likely get a little more love put into your 2.2 .

hummm. I know your right Kurt. Idea dropped. Just got to keep looking for a good deal on a temp running 2.xx flat 6.

But I would be interested in the 912E motor!!!

Motor mounts in your engine bay are different from a 912. Can be done though.

I had one. It was the worst piece of crap I ever called a porsche. It looked o.k. . But man was it slow ! Here`s a few pictures of the slug. I sold it for $7500.00 and the engine blew up 6 month later. He offered it back to me for $2200.00 with a freshly dented fender. I told him not interested. He listed it in the local paper for $3000.00 the next week. Maybe you have it now ?

Hmmmm, a 912E should fit in a 901 trans....the 912E trans was a specially modified 915 that had a 901 shaft.....so yeah...it should work.

As to the rear mount...it should come WITH the motor.

BTW...the 912E motor originally came with L JET fuel injection. If it has Webers on it and it was rebuilt with a carb cam...it ain't no piece of crap.....they can put out 130-150 HP in stock displacement and w/o missing a shift do 100K miles.

What killed the original motors on the 912Es were the thermal reactors....just like the 2,7s of that same era.

Once rebuilt and the reactors hit the ***** can, they ran like a stripped a$$ed ape....

Will no wonder it ran like a slug you had that heavy ass tail on

Can be done the gear box will match but you will need a fly wheel clutch and presure plate. Type 4 will fit fine and will also line up with your starter motor.

The engine mounts are in a different place on the 912, but it is not hard to fabricate them.

I have a set if you need photo.

I've got up close and personal experience with 912e's. Having so much fun putting a 3.0 in mine right now.

To put the 912e motor in the 70 with a 901 would work, but would require some ugly work. To use the 912e rear engine bar, you could have to remove the oil tank and weld in a bracket on each side of the inner fender. The motor should have a 914 style flywheel, clutch and pressure place, so the starter should work, but I think the 70/71 tranny had a different clutch arm, push vs pull or something, not sure it would work.

Then you have little details of the tach having to be changed for a 4 cyl, and the engine wiring would have different senders.

You would also need to make sure you got all the cooling tin with the 912e motor (usually costs about $500 itself if you wanted to buy it).

I would think it would take the 3 months you are planning on the 6 cyl rebuild to get the 4 cyl running in your car, then it would be time to pull it back out.

sounds like wayyyyy tooooo much hassle. I'm on the trail of a good used, but running 2.4 flat 6. I'll be a staight swap except for the clutch. Why the h$#@#%&&* Porsche used this backward clutch in 1970-71 is beyond me.

Just get a conversion flywheel for the trans you are using...Kennedy Engineered Products in Palmdale CA....do a Google.

At last I've found some info.....

I'm looking to fit a VW motor into my 71T....

Has anyone done this....surely the cltch would only need a custom friction plate........the oil tank issue wouldn't be a problem as the VW is a wet sump? ............these are just some of the issues I'm loking for advice on.

Sounds like you'd be better off buying a $500 beater. I bought an old Volvo 240 several years ago as an "interim" car, and the wife fell in love with the thing. If it wasn't so bloody rusty, we probably would've kept the thing and fixed her up. Buy a cheap car that'll get you around, then sell it when you're done. If you buy it smart, you won't lose any money on it.

I have the crossbar and Tin ,if you are lookiing for them.

I'm going to second the beater idea. way less work. you can buy a decent beater for the much less than a tired 911 engine, no problem. Then sell the beater whenever for what you bought it for. You'll be fine driving a beater for a few months... it'll probably motivate you to get the motor done :D
