996 engine in old 911 ?

Kurt B · 08-16-2002, 06:40 AM

Just wondering if anyone knows if this has been done yet. I'd be really curious since these engines are apparently not very expensive. Surely someone MUST have done it.

Gives me a chance to clear up a little confusions. So...which Porsche said it, I do not remember, but it was something like "Putting a water cooled engine in the rear and the radiator up front doesn't make sense"

Well, this statement was made before porsche started putting oil coolers in the front. And it either makes sense for both or for neither, unless there is something magical in moving oil along the chassis.

c'mon..someone slap an effing 996 engine in one of these already.

Well apparently there is, much of the heat dissappation from the oil is done in the lines as it moves down the chassis. I read this somewhere recently, maybe in BA's book?

If it has not ben done already, somebody will. I wonder if before that, somebody goes the other way- Misses the "soul" of their new 996 and puts an air cooled powerplant in it.

Yes it has been done. I've seen a picture of one at this board. Who posted that picture?

I have the pic on another computer if someone wants to see it again.

I have seen such a conversion. At last year's Northern Ohio PCA club race at Nelson Ledges, Kelly Moss Motorsports had a 993 bodied car with 996 engine in the back and a radiator carved out of the trunk in front. The conversion was done b/c club racing rules restrict displacement to 3.6 liters and the 996 engine developes more horsepower.

Reportedly, the owner is a surgeon who has Kelly Moss service and transport his car to the club races. Must be nice.

At the same rate I also saw an early 911 with a 996 body grafted on to the chasis. Club racers have some amaizingly creative machinery.

I would like to see a picture of a 996 motor in a real 911 if anyone can locate one. I have a friend contemplating this swap now that his SC motor failed.

Thanks,

My Mechanic did this to a car for Club Racing. I'll see if he has a picture. He did a great job but I can only imagine how much it must have cost

Cheers, James

Kurt,

Considering that Porsche put oil coolers, a pair, that is, one in each front fender in 1953 for the 550 Spyder ... don't you think your question is a bit out of context?

Porsche_monkey · 08-27-2002, 09:18 AM

Bump.

Are these guys using 911 transmissions?

What is a 996 engine worth? ($$, not comments)

Who has pictures?

Will this piss off the anti-V8 crowd the way a 350 ci would?

Warren - but the 550 engine is in the MIDDLE not the rear!

Not the best picture, but the only one I've got.

"Well apparently there is, much of the heat dissappation from the oil is done in the lines as it moves down the chassis. I read this somewhere recently, maybe in BA's book?"

Small point, but I would probably change that to "some of the heat dissipation..."

A proper oil cooler is the main heat transfer component. The fact that the factory trombone cooler was buried behind the front fender may have contributed to the importance of the hard lines.

Sorry, didn't mean to digress from the main topic.

why would you want to do this in the first place...

Well, a 993 engine makes 280hp from 3.6. A (newest version) 996 engine makes 320, and is apparently cheaper.

It may not be better, but cheaper and more horsepower is a good start.

pwd72s · 08-27-2002, 03:35 PM

It was Dr. Ferry Porsche who made that statement...being interviewed by BJT of Panorama, and when he made the statement, the 911S models had been running front oil radiators for years. To be fair, it was made at the time the 928 was about to emerge...

Ah, heck, wait a few months and graft in a Cayenne V8. Somebody's bound to roll one the first month or so....

Langers · 08-27-2002, 06:12 PM

I've been told by a well respected Porsche mechanic that the 996 engines are blowing up at around 10 000km (6000miles) due to manufacturing defects. They are being replaced under warranty, but I dont know if that warranty would be in place if the engine is out of the car.

re: 82SC - Why

I own a 74 with a 2.7. I will need to upgrade someday. If a 996 engine has more horsepower, why not choose that over a 3.2 or 3.6?

I think I'm going to be sick....I can hear someone asking for some anti-freeze at the next DE and then taken out back and beaten.

This is not exactly a drop-in installation. So for all the hassle involved, why not do something unique and install a 300+ HP V8 928 motor? Just make sure your acetylene tank is topped off before proceding with the conversion.
