Wonder if it's possible....

As long as the engine is happy lying over at an angle like the Porsche engine, there's no reason why not.

Yeah, that could be an issue - but I'm sure the 1.8T was based on the bog-standard VAG block which was essentially what was used in the 924 in the first place. RWD conversion isn't an issue - but hooking it up to a transaxle might be, I suppose.

. Don't really see why.

So long as it can be mated to the front bellhousing, everything else is possible.

I know that Rover V8 conversions have been done.

Having said all of that, the original 2.0 engine which everyone seems to hate is a really keen engine in character. I have had two and like the mechanical character of them. Yep - I would have another.

Heh, it's not that the original engine is crap, it's just that 1.8Ts are cheap these days and would make a lot of sense in a 924 - 225bhp and very little weight with RWD and decent weight distribution would make an excellent track car.

Unfortunately the 924 doesn't have the bog standard VAG block. I looked into doing a VW 16V Turbo into a 924 before the 1.8T came out. Unfortunately the bellhousing and torque tube from the 924 don't bolt onto the VW 16V block which means they won't bolt onto the 1.8T block either. This is a conversion I want to do but there's not a parts bin option, a custom adaptor is required to fit the 924 bellhousing to the 16V/1.8T block. There is a RWD bellhousing available to bolt a Ford Type9 or Bord Warner T5 gearbox to the 1.8T so it's not impossible to use a 1.8T in RWD with a bit of work but a 924 probably isn't the best place to start :-(

Why, coz of engine bay size? Dry sump it...

Interesting - and puts a stop to that train of thought.

Shame, really, 'cos I thought there might be some mileage in raiding the VAG parts bin.

There'd be a way to do it if you really wanted to. Either getting an adaptor made up or perhaps cutting the flange off the bellhousing and welding on a flange from a 1.8T gearbox, assuming they're the same material. It's just a shame they didn't use the VW 1.8 GTI engine instead which would have made it an easy conversion.

I was making the assumption that the 2lt block was the same - 'cos I couldn't see any reason why it wouldn't be.

Looking at what you've said, it's not a realistic project to do, 'cos it's not a straight-ish swap.

I'm intending fitting a non standard box to my SD1 and this seems to be the way to go. But it's somewhat beyond my capabilities - do you know any specialists that undertake such work?

Might be better seeing what was fitted to the Audi 80/90/100/200 series at the time.

Yes I know the 924 used the LT van engine, but it was an audi design project. Maybe a 200 turbo lump might be a better fit than a vw 1.8T

Not as modern, but maybe as punchy, certainly period and maybe easier to do. Would they both have been K-jet too?

Says they used the Audi 100 2.0 engine. And there was a C2 series Audi

100 turbo quattro.

Theory would suggest it was doable if the torque tube to the transaxle will take the abuse.

I know that, apart from the 5-pots, and the 2lt engine which is the same anyway, they used a lot of VW 1.8 GTI-based blocks.

Added complication of a 5 cylinder lump being put into a bay designed for a 4-pot.

The 924 uses K-Jet, yes. Not exactly what you need when looking for extra power, though.

Isn't that a 5-pot, though?

Given that Porsche made both a Turbo and a 2.5 engined version, I'd say that was the least of the potential problems.

Possibly. But not sure how crowded the 100 engine bay is compared to the

924. If they could fit a 4 and 5 pot engine in the 100, you might be able to do the same to the 924.

Also, if they are both K-jet, just swap over like for like and they will both already be setup. Use the 100 turbo K-Jet kit in the 924 and the turbo engine will already have the extra injector feed from the 5 pot fuel distributor, and the extra fuel the turbo engine needs.

Not offhand but I'd look for a motorsport engineering company. There was an article in Practical Performance Car several months ago about making your own bellhousing. What gearbox are you looking to use? There's often bellhousings already available for most common engines.

A bloke on Locostbuilders has fitted an Alfa V6 to a type 9 in his Locost.

That involved milling the original flange off the type 9 and welding on the Alfa flange.

A bit involved, but perfectly doable.

Can't you fit an R380 to the SD1 ? Or what did you have in mind ?

The gearbox I'd like to use doesn't have a removable one.

That's the method that appeals to me - rather than a spacer.

I'm hoping to have a go at fitting a ZF 5HP 18 - an auto - to replace the

3 speed original. I realise there will be problems with the electronics - but what the hell. ;-) And unfortunately it doesn't have a removable bellhousing. Not that it would help anyway as they've never been mated anyway.

I thought it would be easy to fit a Range Rover 4HP - but in that installation Rover spaced the torque convertor off the drive and made the bellhousing much larger than needed to fill the space between engine and transfer box where the longer manual goes - and the longer bellhousing fouls the bulkhead.
