V8 conversion

Sorry Ross if we come across as negative but it's just the sort of caring people we are. If someone came on the forum saying they wanted to fill their underpants with deadly vipers we would probably try to dissuade them from that as well. [;)]

On the other hand, there are no rules about being eccentric and 300bhp without lag, and boost bash, would certainly make for a nice car.......and think of the noise. [8D]

I seem to recall the LS1 conversion parts came from a company in the States - something like Venom Racing.

But that's not answering the gent's question.

Ross - there are two chaps on Pistonheads I'd suggest you contact. One is Iguana, who knows a LOT about 944's, and I think built the V8 lux which has a short write-up in a PH feature (I presume you have read that feature - non?)

The other is a chap called Wildoliver who I had a conversation about recently about fitting an Audi V8 into a 944. He swore it was possible ... but was very knowledgable about bellhousings and what bolts to what. He would be a good contact, and has a stock of 944 and 924 parts as well, should you need them.

For all I know both of those PH people (Iguana and Wildoliver) post on here under different guises. If so, please make yourselves known, chaps!

Keep us posted with the progress. I can associate with the fun of making unusual bits of machinery work, and the appeal of a cheap project is neverending!

eccentric ? lol, i'll go with that ... [;)]

thanks for the links guy's.. Ive seen the renegade hybrid site, and read iguana's write-up on "Mr X's" 944 v8, but neither is particularly detailed, and the "porsche hybrids" site/forum is almost exclusively devoted to the american engines..

if the audi v8 fits I could be tempted by that, (its a far more sophisticated engine after all) but i think from the reading i did first time round on 924.org (when planning on a 924 conversion) suggested that it was too wide.
 
The VAG 20v turbo uses the same legacy engine block as the 924 engine. Thatll bolt straight up to a 931 torque tube and snailshell transaxle...
 
Ross,

Mr X's car was the one I was referring too.

The Audi V8 conversion (on an S2, but would apply to any 944) was discussed at a very high level here:

http://pistonheads.com/gassing/topic.asp?h=0&f=48&t=599365&nmt=998%20/%20Porsche%20fantasy

(Ignore the thread title - it is towards the end.) Wildoliver seems very confident it will work, but I can't believe it would be that easy. (If it was, I think it would have been done by now.) I suspect that Simon M (944man)'s comments above may be accurate ... if it IS possible, I could be quite interested in it as well.


Oli.
 
Im not sure, but I was told that the blocks were identical (with the 20vT's block still having provision for a camshaft, left from the original DKW OHV unit - and people thought that it really was an LT van engine...) by a well-respected engine builder. From my conversation I am happy that he is correct, hence my repeating it.

interesting ..

audi lumps will bolt to 924/931 bellhousings which will bolt to the 924/931/944 torque tube .. just need a custom flywheel.. and suitable clutch ..

so a stupidly quick audi V8 powered 944 is feasible ..

but im really not sure it'll fit between the struts or clear the bonnet.. have to get the tape measure out :)


The approx sizes of the Audi ABZ V8 engine -
Length of engine (front pulley to bellhousing face) = 490mm (19 3/16")
Max width of engine (across exhaust manifolds) = 760mm (29 15/16")
Max height of engine (sump to idle air valve) = 660mm (26")
 
A 928 (probably a two valve head model though) V8 will fit. I know because Ive seen a 944 race series prototype, which was built about 15 years ago. I cant remember it well enough to recall whether it an S2 or an S4 engine...
 
Really?

I thought those were definitely to wide across the heads to fit between the 944 strut towers without cutting a lot of metal out and fitting a frame in its place.


Oli.
 
oli's right, they dont fit in a stock shell, the racers are almost spaceframed at the front...

rover V8 dimensions (nicked from web, so probably wrong)

H = 71.1cm
W = 76.2cm
L = 84.3cm

compared to audi V8 (similarly unsubstantiated)

H = 66.0cm
W = 76.0cm
L = 49.0cm

so it's looking possible from that.. real things and a tape measure are required ...

this audi V8 has piqued my interest, its closer to being "in the family" than the rover .. and far more modern to boot.

it'll cost more, but not a stupid amount.
 
It wasnt a space frame, but as it was almost 15 years ago Im struggling to remember much beyond that it had been shoehorned in.

Surely you can get more than 350bhp out of a Rover v8 can't you? I thought the 6R4's were getting a load more than that with 2 cylinders lopped off.

Apparently pretty much all Audi engines use the same mounting hole patterns so should bold upto a 944 torque tube. So why not an engine from the Audi stable? Apparently there are a few kicking about due to the Aluminium Audi A8's being difficult and V. expensive to repair after they've been pranged meaning alot are written off. A work collegue, who also likes to mess around with cars, is transplanting a 4.2ltr V8 out of a German A8 into an Audi 80 - just for a laugh.

The 6R4's engine was a turbo and I'm pretty sure that it did not origionate from the Rover/Buick unit (Overhead cams rather than pushrods etc.). Intrestingly it was the same engine that ended up in the XJ220 (even though Jaguar/TWR would never admit to it), good for over 800HP in race trim.
Now THAT would be intresting!

The prototype 6R4 started out as a cut down rover block .. but the "production" units were bespoke .. or something .. but yeh they were turbo'd anyway werent they ?

the buick lump saw service in F1 for a while too albeit in highly modified form.

The 6R4 engine was normally aspirated; and its nothing to do with the Buick V8. The engine was used as a base for the Jaguar XJ220 engine, in which guise it was turbocharged.
 
I always thought that a 6cyl M3 unit would be a good transplant into a 944. Probably plenty of them available (particularly from the slightly less than fine handling model 2 genarations ago). Much more modern engine with a vast amount of tuning options courtsey of the multitude of Germans tuning firms.
Anybody tried one of these?

Yes, sorry it was N/A.
