Ok, I have possession of a petrol VW LT Luton (yeah I know.... why!)
Its the audi 2.0 on a carb and is gutless.
Seeing as 924 engines seem cheap and are allegedly "breathed upon" audi 2.0's of the same vintage, I'm wondering if I could swap one in? Plus they are fuel injection so theoretically more reliable?
(I'm aware that the van one should be tuned for low down torque vs the porka, but seriously this engine is gutless)
Either that or any dizzle options that bolt up? needs to be mega cheaps. Not looking for the last word in performance / speed / economy just a tad more oomph and reliability.
Cheers
Mark

Think they are not for off being the same at least from memory my 924 was so disapointingly gutless I gave it away .. 82 on a private road foot on the floor ..

well, you should have the 2.0 with 75 BHP, the Porsche 924 has a K-Jetronic mechanical injection and 125 BHP, i am not sure, if the engine fits (it's the same block, but due to the transaxle design/clutch arrangement on the 924 it could be different. There was also an engine with 115 BHP available in the Mk.II Audi 100 , this could be easier to adapt due to being carbed, though hard to source these days . Also the Audi 5pot fits the gearbox, as well as the VW 6pot Diesel, which was LT exclusive for VW, though Volvo fitted them to their passenger cars ... the early LT diesels had a Perkins Diesel engine ... so lots of choices , as petrol the 5pot might be interesting, and the 6pot Diesel is just great ....

924 lumps are pretty cheap and reliable, they don't die they just wear out, but there are plenty of runners that are worn out.
A 'mint' 924 crank power curve from a RR session a while back:
Revs/Power/Torque
1500/60/17
2000/65/25
2500/70/33
3000/80/46
3500/90/60
4000/100/76
4500/120/103
5000/120/114
5500/115/120
6000/105/120
6500/95/118
(Edit: those are Rounded to nearest 5)

thanks guys, didnt realise they were mech injection though! is that problematic? Thanks for the figures scruff, but have you got torque and power the wrong way round? Interesting that a 5 cylinder may fit haha  |

Nope, peak torque is about 4.5k peak power is 5.5k redline 6.5k ish.
5 pot is about 2.5" longer than the 4 pot.
Bosch K-Jetronic Mech injection isn't a problem if it works, if it doesn't work it can be a bit of a pig.
It's well understood (It's been around on Porsches, mercs, fords, BMWs, volvos, etc for years) but fault finsding is best done by proper fault diagnosis, some parts are expensive new and none-existant second hand (Fuel accumulators).
That said if they run, they run well, the main killer is fuel varnish so they don't like being stood for long periods if the fuel drys up.
Problems you will ahev with the 5 pots is that the 924 is a crossflow ehad but the 10v 5 pot is not, the 20V 5 pot is a cross flow but they cost a lot more and have electrci fuel injection.
How about a 924 lump on twin 40s? They make around 140 bhp. Cast ali manifolds are available too.

Are these a different bell housing pattern to most of the other VW stuff out there then? I was under the impression basically everything Audi and VW make shares it's bell housing pattern, bar perhaps the V6/8 Audi lumps.

What about the 2.5 - that's meant to be a bit better. I did find the 2000cc engine a bit gutless.
I don't know about the bellhousings though, I think they're attached with a torque tube on the 924/944's.

LOL at twin 40s on a 924 lump in a luton van, this appeals to my sense of daftness but the funds wouldnt stretch at the mo. Think a 5 cylinder may well be a good option, doesnt matter if the exhaust comes out the other side as there is quite a lot of space under that engine cover. in fact it would probably make the drivers seat a considerably more pleasant place to be! (plus I LOVE the noise a 5 cylinder anything makes)
Robin..... it would be interesting to know what audi engines fit what for sure.
David...... not fitting a 2.5! too expensive and bits cost too much. This is literally a no-budget swap idea. minimal cash available.

Interesting that a 5 cylinder may fit haha LT35s came with a 5-cyl as stock, and they sound immense! |

5pot FTW then. I'd love a 5 pot turbo lump in my 924, there were rumours that is what the 924 was built for and they will fit...
The 924, 924S, 924 Turbo and audi lumps of that era all share a bell housing pattern but the engines tend to be canted over by a few degrees to get it under the bonnet.
The bell housing is a bit of a red herring, yes they are on the torque tube but the torque tube is literally just an extension between the engine and box, if you pull the engine out it'll bolt right up to the gearbox.

look out for the volvo td lump, its the best solution all round, the 924, 944 and 924 turbo are all gutless, tried insuring all at 18, and not only where they over priced, but not worth money in power terms. however 944 turbo, and audi 5cyl turbos are brilliant.
i'd avoid the perkins 4203 lumps as they aren't ideal.
In truth however the lt35 as a luton will never be quick even large cliff i don't think will get you to national speed limit. with a 2.4td you'll get a comfotable 65 and ok mpg.
Any idea of size of luton. give you an idea "3.5ton" 1100 cube will get about 22 with a 2.4td

Hi,
This is a bit late but thought I would add it here, the Audi 4 cylinder engines and 5 cylinder engines do not share the same bolt pattern for the gearbox.
As far as I am aware all 4 cylinders will interchange as will all 5 cylinders but not with each other!
So if your engine is a 4 cylinder then you will need to change the gearbox as well if you want to use a 5 pot.
This what I have read on Audi Forums tho, I have not confirmed this first hand.
