skinnerd - shuie...i would like to see a conversion for a 914 as well.

if i remember correctly, to fit a 996 into a boxter they had to rotate the engine to like a 45 degree angle to get it to fit. That would lead me to believe that the boxter engine may be smaller than the 996.

There's a guy here in town that's trying to get a Boxster S engine into a 914. So far, they've realized that you can't bolt the Boxster engine to a 915, so they had to buy a Boxster S transmission, also. I'm not sure what they've done as far as plumbing for coolant.

That is incorrect. The 996 engine is nearly a direct boltup in a Boxster - you just have to reroute some of the oil, air, and fuel lines. No tilting required. A Boxster engine, dimensionally, is nearly identical to a 996 engine.

Thanks Steve. I read that about the 915 somewhere after I posted the links. In addition to the transmission issue I also read that you need to use a Boxster dash to get all of the eletrical stuff right.

I'm thinking the whole Boxster coil springs, brakes, suspension as possible and the motor/tranny would be outstanding.

Don't look to me to do it. I've had my fill of 914s.

Utterly ignorant question: Do 911 and boxster flywheels spin in the same direction? If not, then would you have to flip the tranny?

Janus, I think you have to use the Boxster tranny.

3.2 s engine

Thought I would revive this thread to hopefully gather some up to date info from people who must have done a few of these by now.

I know of a 2004 3.2 s salvage car, complete, 51,000 miles, manual, for not many bucks. I got to thinking whether I could shoe horn the complete engine and transmission into my 1965 911. Much better bangs per buck than a 3.2 or 3.6 air cooled engine. I'd keep the existing (non original) 2.0l engine and 901-01 gearbox for later on.

Cooling is not a major problem as I know Renegade have 'perfected' that side of things and the boxster is complete with its cooling radiators so I think I'm right in saying the main issue is the engine management system / electronics. I'm wondering whether I just convert the Boxster engine to PMO's and treat it as an analogue lump as opposed to digital (kinda retro).

There's plenty of horse power in the original digital version (262) so I could sacrifice a few for a simpler install.

Any thoughts or experience guys?

The easiest conversion would be the renegade conversion with a simple carbureted v8...

Lots of the renegade conversion I see on youtube have high horsepower electronically managed engines, that need serious cooling... Most of the conversion seem to come out costing 20-30k when its all done. Hardly cheap.

Always thought it would be neat to do a suburu conversion, as its light, and throw in an older nonelectronic suburu motor...

Putting in a boxster motor would be really cool when its all done. But figure it will take you 5+ years to get it done and countless hours...

Supplied new to Germany 1965, then ended up in the states where it was converted to a club racer IROC style, 1990 went from the states to Finland, passed through 3 owners there and came to me in the UK a month ago. Currently has a standard 1965 2.0 engine, but in its racing days had a 2.5 litre short stroke, allegedly.

Nothing is impossible with the proper budget. If you're looking to save money rather than re-building the air-cooled I doubt it would pencil out for all the reasons already stated - cooling plumbing being the biggest.

The guy who bought my 914 said a Boxster transplant was his plan for my car ( sadly ) but what-ev's..I mentioned that I don't think that has been done before , he said he was well aware of that but that was his plan. Not sure what ever ended up happening with the car> I hope there was no cutting! I thought the OEM 1.7 was pretty fun actually.
On the interwebs I did see an 8 cyl 928 stuffed in a 914, so anything is possible.
Ultimately, from a purely engineering perspective: you would be better off just driving a Boxster. The mid-engine-ed Boxster is a better place to have a lump of engine..rear configuration is the second best place to have that much weight.

Down-side, many?
Up-side:You would still be driving a 100% Porsche

Water cooled in old 911

Here you go - a few pics of a friends monster water pumper . . .
He bought it already done . . . didn't do the work . . . only kept it a while and passed it on to buy Cup car . . .

I came across this said to be 914 based build at a car show here in Panama City Beach.

BIG show. 1,000 cars and trucks or so. Only saw two Porsche,, this and a V8 conversion 996.




Looks to be widened out in the rear.



I didn't get a lot of details, maybe some of you will recognize some of the parts going into this amazing build.

With that windshield and those doors, it looks more modern, but this thing has been worked over pretty extensively.

What do y'all see?

The M96/M97 engines are fundamentally different from the Mezger engines, and will not fit a 911 without major modifications. The gearbox/engine flange is completely different, where the M96/M97 have a VW/Audi flange. You would either need an adapter (that would push the engine rearwards, not good...), or a G96 gearbox, that is MUCH bigger than a 915 or G50. In addition to cutting and enlarging the gearbox tunell, you would need to cut the torque tubes and go with coil overs. Also, the M96/M97 have the starter motor on the engine, while the Mezger motors have the starter on the gearbox.
The only water cooled engine the really fits, is the Mezger Turbo/GT2/GT3 engine, that is a bolt on to a 915 or G50. However, the 915 would become "spaghetti" pretty quick. You can get a 996 Turbo engine in OK condition for around $15k. But you will still need the radiators and plumbing, and other mods.
If you want a cheap water-boxer, buy a Boxster! They are fantastic cars, better than the contemporary 996/997/991 cars in my opinion. If you want a cheap 911, forget it. They don't exist.

Great feedback. I'm still wondering if anyone has done the conversion and if so how it turned out.

Maybe someone has mounted a Boxster/Cayman drive train amidships as a mid engine set up? That could get rid of a lot of the issues with it being a bigger lump than the original 911 drive train and improve the handling perhaps.

Didn't I read that Porsche have just released a limited number of 911's with a mid engine layout, or did I dream that?

Here is a VW bug with a Boxster engine

Anything can be done!!!

If I had the coin I would finance the first SWB chassis with a mid-engine Boxster drivetrain.
