Audi RS2 Engine 944?

[carreraboy]

Think these are a standard 305BHP but give ++++ with a chip etc ... All Porsche Built in Zuffy ... is this engine anywhere near the Turbo 944?

Hi

Basically - no. Its a 5 cylinder Audi engine and trans, only the brakes and wheels are Porsche.

Dont know if it would fit thou'!

There was a chap in the states who transplanted one. They are very very heavy though. Cast iron block, very robustly built - which is why they can be cranked up to make huge HP. He also installed it with a Supra transmission right behind the engine - so got rid of the transaxel so the car would have massively been nose heavy. Clearly not suitable for anything but a straight road. I like the 5 cylinder concept though and think that the modern incarnation of this engine is the 5cyl turbo Volvo unit in the Focus ST. Makes good HP, very tunable, not sure of the weight of the engine but has got to be all-alloy - the only problem might be is that it is not a canted design so you wont be able to fit it under the bonnet without a huge unsightly bonnet bulge.

I have in idle moments been considering a twin turbo Audi V6 - I think if the front engine line had continued we could have got one anyway, being a V6 it is shorter than a 4 so should be ok on the weight distribution. No idea if it will fit though - need to measure one, I think the previous RS4 had one (developed by cosworth but rare and fragile) and the up to 2005 S6 had one in a lower state of tune.

I agree VAG V6 would be the way to go, either twin turbo or NA from one of the more modern cars with a nice fruity exhaust. Definitely not the V8 from a 928 though, waay too big and heavy, expensive to maintain and ultimately not as tuneable as a GM lump. This topic has come up before in various guises and I definitely remember a consensus towards something like the VAG V6.

LSx is the only sensible option isn't it? [] It looks like a factory job in LHD cars - the engine is very compact, robust, and is nice & light.

I saw an E30 track car with a 520hp LS1 last week at Donington - beautiful car and hugely fast. The engine looked right at home in the E30 engine bay as well.

( I believe a certain midlands based Porsche / Holden tuning outfit are developing a RHD LSx transplant - still early in development though.)

Anything is possible, but as many said, the all iron 5 cylinder Audi lump
might not work so well for the poise and balance of the 944.

I remember seeing a like to this on the forum while back, guy in
Sweden, and as you can see from the picture gallery a LOT of work
went into it!

Here's a guy fitting a VR6 in a 944
Seemed to fit quite nicely, albeit a twee bit tall.

Another thread with guys discussing that here too.

When it comes down to pound per horsie though, it is hard to beat
the Chevy!

But if we all liked the same things, it'd be a very dull world, wouldn't it?

I had a discussion with a chap on Pistonheads recently about this sort of thing. He swore that the RS2 lump would fit the 944 - apparently all audi engines have the same bolt pattern on the end that bolts to the gearbox, so any such engine would bolt up to the torque tube in the 944.

He claimed to have attempted it, and tried to do a 4WD conversion at the same time. He said the engine conversion was easy, but he came unstuck on the 4WD bit and gave up. How much of that is true I don't know.

Not I, but I'd hazard a guess. I have doubts over the former claim and even more doubts over the latter.

This is true.

I heard all audi gearboxes fitted all audi engines and got quite excited - less so when I discovered that the gearboxes have multiple fixing options,

[carreraboy]

Surely it would be a straight transplant into a 924 as it's Audi to Audi?

 

[944Turbo]

Maybe, and did they re-engineer the torque tube for the 2.5 litre? However the engines have differences, the audi gearboxes have multiple fixing options to suit the different engines,

Scott, that guy is actually in Sweden I believe. While the car started very much in the 'project' mold I think it turned out pretty impressively.

wouldnt it be easier to use the 1.8t audi engine as found in my S3, ok the powers not as high but can be bought upto 300+ bhp easily enough

 

[barks944]

Whats the Audi 1.8T unit like off boost?

I know for a fact that an S2 gearbox will bolt straight upto a 42.ltr v8 from an A8 and similarly the 5cyl Audi engines will bolt straight upto an S2 gearbox.

Difficult to say Tom, they have so little lag. They have a higher compression ratio and much much smaller turbo.

I agree, it was an impressive project by all measures, but for me there is no engine in the world you could put under the bonnet that would compensate for ruining the dynamics of a 944. It is by far the cars strongest asset.

Ding, and verily dong. As an example of engineering prowess it is great; as a route to something that is better than the original then I think he is decieved. I'd be interested to know how it did handle once he was complete. And that remains the appeal (to me) of the GM V8 LS2 lump into a 944 - the weight is very similar, and the dynamics preserved.

(As an aside, fitting a VR6 to a Mk2 Golf was a popular project about 12 years ago, but you had to cant it forwards and thus spoiled the car's handling. I always wondered why people did that too.)

but the gearbox end is different from the torque tube end isn't it? Scott do you know if the v6 fits onto the gearbox? Might be a little impractical having it in the back seats though [&:]
