450 HP Cayenne V8 Biturbo in a 944!

I have generally been against the Cayenne project. I mean, a Porsche SUV? <img src="graemlins/crying.gif" border="0" alt="[crying]" /> 'Tis a shame.
But in developing the platform, PAG has produced a new V8 engine that generates 450 HP and 460 lb-ft of torque (same amount as the 911 GT2 but at 1250 fewer revs) available to 4750 rpm. Hmmmmm....
Now...suppose you got a nice clean 944 with upgraded Big Red brakes and 030 suspension...and then you plopped that massive V8 into its heart.
Is this possible? Doable? Reasonable? Could you build this supercar on the cheap? Your thoughts?
It would make me feel like Dr. Frankenstein breathing life into my monster. Happy Halloween!

On the cheap? Not a chance....
you can do most anything with enough money to throw at a problem though.
That is a very large engine.
I'd like to see it!
On the same note - why haven't we heard of more people swapping the 928 engine into their '44?
Size issues? Or money issues?

This discussion has been brought up by 928-owners and I believe that the conclusion they made was that the engine was to wide for the 928...
Since the 928 enginebay is wider than a 944 enginebay it is probably not doable without making a tube chassis...
It would be pretty cool though.

I would think money issues, but it is also pretty heavy. American V-8's are everywhere and cheap and will fit (though it is VERY tight). So why go Porsche on that swap? If I did it and I'm not saying I would -- I'd go 350 cu as well.

You'd probably be paying 25K bucks for just the engine. Although I don't know for sure. Wait until some yuppies wreck them after the first week because they don't know what to do when the boost comes on.

Of course that would really stoke the fires about "is it a REAL Porsche?"!!!

Width issues kill both the 928 and Cayenne engine swaps into the 944... All that sheetmetal along the inner sides under the hood is _structural_, so you can't just whack it out with a sawzall. You could, with enough cubic dollars, build a tubular front subframe that would probably accomodate either engine, but you'd have to design a new front suspension as well. As mentioned, there'd be the question of drivetrain life... short, even tho' sweet.
It'd probably be possible to do the Cayenne-into-a-928 swap, with the cost of the donor motor being the major drawback. Probably (almost certainly) cheaper to go with a highly-modded late 928 engine.
But the narrower US V-8's are about the only practical swaps into a 944, unless you've got or can buy access to a race-car frame fab shop & designer. Pricey, that.

How about the Toyota 2JZ-GTE (Supra Twin-turbo I6)? I think that'd be a killer swap. That engine can handle over 1000 horsepower (I have a dyno video of one in particular). Stock it is rated at 320 hp, but a BPU 2JZ-GTE produces about 450 horsepower or so...thats on the stock turbos.
Check out this page. A kit to produce 1200 horsepower on your Supra. <a href="http://www.suprastore.com/45suppac.html" target="_blank">http://www.suprastore.com/45suppac.html</a>
The owner of the Supra Store had the highest non-nitrous Supra this year at the Las Vegas Supra Meet. He dynoed 903 RWHP. The highest dyno this year (including nitrous) was 1121 RWHP.
Imagine a motor like that in a 944...holy crap!

Sean, judging by the size of the motor and the, W-shape similar to the 928 motors, it will be an EXTREMELY tight fit. Kelly Moss managed to get a 928 motor in a 944, BUT he had to convert it to a tubular frame upfront in order to maintain a reasonable clearance. The inner fenders will also have to be taken out and a custom inner fender fabricated to accommodate the large motor. I know of only one person who shoved an 82 4.5L into a 944 and got some very fast results. He did only minor modifications to get the motor to fit in as well as install 924 GTR headlights for extra clearance inside the engine bay. I haven't talked to him in a while but it sure was an interesting project i saw from the pictures. <img src="graemlins/bigok.gif" border="0" alt="[thumbsup]" /> I give that guy big big props <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />
As for that Cayenne twin turbo V8, that baby is gonna go in my 928 S4 as soon as I see the first rear ended one at the local BMW/Porsche yard!

oh if that was possible i'd be the first customer. that is such a cool and reliable high power engine and it probably isn't too different in size being that the displacement is the same. any idea what it would take to do this? cause i'm really interested.

I have no idea who could do the swap. Obviously, it would be a lot of work. If the engine was just too big, another great engine to swap with would be the SR20DET (Silva Spec-R).
Anyways, check out this Toyota pickup with a 2JZ-GTE.
