That all depends, how you go about asking certain questions....[][][][][][]

He is actually a nice bloke, but he likes to be obtuse (or just really f*cking rude sometimes). He told me that he does it to see if people are serious or just wasting his time.

When I had my old car it ran megasquirt, great bit of kit and a great price.

When the engine blew in my lux I was thinking about the 20v turbo, thinking how hard it would be to fit. But I think it would be too tall and if you moved it at an angle the turbo would hit the wing. I picked my old BAM (Audi TT 225bhp) engine with loom, ecu, clocks and keys for 1k so not bad money.

I can feel a new project coming on.......

The reason that I mentioned it (apart from to get people talking) was because I have it on good authority that the block is based on the original Mercedes/DKW - Auto Union - AUDI/VAG block used in the 924! Apparently it still has provision for the camsahft in the block... If this is so then mating it to a torque tube and securing it to a 924 crossmember shouldnt be too difficult: pretty much bolt-in, in fact. Id guess that the early lontitudinal AUDI big port version would be best?

Its the AEB that I think would be most suitable, but Im far from certain. Theyre designed to fit the right way around, but even though theyre large port versions, they are only expected to make 200bhp...

VAG 1.8t is a very uninspiring engine. Dutiful and powerful, but almost entirely devoid of character. I would take issue with Fen in that I don't think they sound anything other than flat either. The thought of fitting one into a 944 is, to me, a ghastly one. Their only redeeming feature in my eyes is that they are cheap, plentiful, and very cheap to tune to pretty good figures. But I wouldn't really want one.

The Chevy V8 conversion is something I have been very rude about on here before. However, the more I hear about the LS1 engine the more I like the sound of it. I'd be quite interested to see one 'in the tin'.

I had a brain fart and thought they were 5 cylinder when I said they might sound good (I'm stoned on codeine). Of course they have 4 cylinders each with 5 valves, and therefore sound boring.

 

[homesea]

Nothing boring about them in a mk1 golf when they are running over 250bhp with very little lag. But in a TT or Golf mk4 or the 100 other cars they were put in they are very boring. Any 4 port sounds rubbish, unless its on twin carbs with a striaght through exhaust.

Ok then how about the VW VR6 or the 3.2 from the R32 then add a charger?? Or the old Audi 20v from the S2 etc that porsche played with for the RS2?

Oh, I dunno: the Mk2 Escort I used to co-drive, with an injected Cosworth BDA sounded OK, especially around its 9.5k rally stage limit..and it was quietened to pass 100 dba.
Lovely noise, 252 bhp at the wheels, and around 6-8 Mpg...

 

[944 man]

Youre missing the point. If VAG have used a legacy engine block, then itll bolt right in.....

 

[zcacogp]

I believe that VW did use a legacy engine block, but that doesn't make it appealing!

(VW also made an enticing range of 1100 and 1300cc engines from the original Mk1 Golf that would probably bolt straight in too. But I wouldn't fit one of those either.)

Oli.

Fen - Enjoy the Codeine. I remember it as being very pleasant stuff ... the fact that you have been prescribed it implies that there is significant pain tho', which I am sorry to hear about ...

Would that fit?

Interesting ... that does (as Fen rightly said) sound somewhat more tuneful. Or, as is currently being suggested in a similar thread over on PH, what about the Audi V8 from the S6? Would that bolt in?

[homesea]

Wow, why stop their. How about the Audi RS8 / Lamborghini engine?[]

 

[edh]

Not sure the VAG 1.8 I4 will bolt in - try 924.org for good info on engine swaps

they suggest the 20V I5 is compatible with the 931 bellhousing & may be a better start point

 

[944 man]

Im only going on What Kev Eacock told me. He certainly knows what the back of a 924 block looks like and he had just looked at an 1800 20v.

Those 5 cyl 20v lumps can make good power but boy are they heavy. Massive big lumbering cast iron block. You'd destroy the subtle dynamics of the 944 if you installed one of those.

 

[944Turbo]

I got excited towards the prospect when I heard any Audi blockfits on any Audi gearbox - 20V 5 can produce over 500bhp relatively cheaply, 4.2V8 easily available etc. Turns out the gearboxes have lots of holes in them allowing them to meet different engines - just put bolts in the holes that line up.

[Diver944]

I would think a 4.2 V8 would soon put lots of extra holes in one of our gearboxes anyway

Lot's of people have talked about fitting a MS and it is always billed as being really easy. To date I have yet to hear of one on a 944 in the UK so I hope Simon's is the first success story. For me my own time is far too valuable to be spent taking weeks to fit and tune something not specifically designed for the car. The Vitesse MAF and piggyback have been tailored to work with our cars straight out of the box - and it did []

You pays your money........

 

[edh]

Unfortunately our Audi gearbox isn't very easy to bolt on to the back of an engine block, unless you're going mid-engined []. I'd love to see a VAG 1.8T in a 924 - would be very cheap power. But if it was easy, I'm sure it would have been done by the 924 guys.

More info on Audi motors / 944 later on in this thread (main topic is an audi lump with Supra box, so not exactly bolt-in )

I like the idea of the 4.2 V8 in a 944 - with turbos of course. Somehow I suspect it isn't going to fit in the hole in the front of the '44 though.

 

[zcacogp]

Fen,

I agree on the size front, but in a discussion that happened in parallel here:

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

... there is what sounds like a knowledgable bloke who seems pretty confident that it would fit. Have a read - interesting stuff starts about half-way down the page. I'm zcacogp (as on here.)

I haven't seen it out of the car, but my RS6 engine looked an order or magnitude bigger than the 944 has room for. I'd expect it to be too wide and too tall. The chap says it will fit 100% but only mentions mounts, so I don't know he's considered dimensions. He apparently doesn't know how surprisingly compact the Chevy engine is, and he thought the 5 cylinder would fit in a 924 and allow use of the 4wd system which he found not to be the case. I'm not ready to believe it would fit until he's fitted it.

As an aside the OP of that post is a complete nutter living in Cloud Cuckoo Land, but RH do a kit to fit the Chevy lump into the back of a 911.

Bizarre how things work - the idea of the 4.2 V8 in a 944 sort of came to my mind through a TiPEC thread just 30 minutes ago.
