Hi all, I need some help from the VW and Audi experts among you.
I've got a project that I would like to use the transaxle from an audi a4 in, but I'm not sure which engines will bolt up to it. I think the transaxle is coded as a DWH which is from a 1.8 non turbo A4, circa 2000. In the ideal world I'd like to mate it with the 1.6 engine found in a mk3 golf, but not sure if they will mate together?
Or what other options do I have? This needs to be a simple engine that I can use the stock ecu with, doesn't need to be powerful just a basic 8v engine would be fine.
Anyone have any ideas on what would fit to it?

The A4 4 cylinder gearbox would likely fit the 1.6 engine. But being a transverse engine you might need to change some things like flywheel, clutch and startermotor.
It would be easiest to also use an A4 engine then.

Thanks. I had ruled out the A4 engine because I thought the wiring wouldn't be very swap friendly, I need to squeeze it into a Lotus Europa.
I don't mind swapping bits around as long as the engine will actually bolt up to the transaxle. Possibly the polo mk3 gti engine was another that looked like it could fit in the space I have.

Basically the same transaxle is used in the A80 & 90 as well as many Passat (not b3/b4).
I think you’ll find that any of the “big block” engines, so 1500, 1600, 1800 and 2L from the Mk1/2/3 Golf, Passat b1 & b2, A80/90 will share the bell housing pattern but not necessarily the flywheel and clutch as the transverse engines of that era had a back-to-front arrangement.
Engines are canted a fair way to the drivers side, but expect you know that.

Beware later 1.6 engines from mk4 Golf & Polo as I think you’ll find they are “small block” and won’t fit, though I could be wrong about that.

Thanks for the info, that's a good starting point. Do you know if there is much size difference between big block and small block?
Whatever engine I use it needs to be compact but still fit on the audi transaxle. The goal here is to make the car reliable so it has to be an efi engine with a usable ecu.

if you have the immobiliser removed from the ecu the I can't think why you couldn't use any of the engines on the transaxle, probably the simplest would be a PD engine they don't lean over that much, probably a similar angle to what they sit at in a transverse vehicle as they still have the exhaust/turbo etc on the back/right side of the engine bay.

I need to squeeze it into a Lotus Europa. I just thought about this, but doesnt the Europa use a Chapman Strut in the rear? Or is it converted to a double wishbone or twinlink suspension. Because I don't think these transmissions are capable of having suspension arm loads placed on the diff flanges. Also, if you'd prefer older 4 cylinder engines from volkswagen, using an older Audi 80 transmission could be the solution.

If I did go through with the conversion I would convert it to double wishbone in the rear, I think there is a kit available for it. That suspension setup is one of the reasons for wanting to change it, everything is worn out including the engine and gearbox. Is the 80 transmission smaller? I have very little knowledge of VAG stuff. Not too fussed on what engine it is, but I wanted efi purely so it can be trusted to be reliable. I'm only looking at the VW engines because the transaxle is cheap and plentiful.

I believe the Toyota 4A-GE twin cam has been fitted to quite a few Europa's or you could go bigger ![;)](//storage.proboards.com/forum/images/smiley/wink.png) Would a Renault transaxle make more sense, since some Europa's had Renault engines originally

Renault transaxle will be harder to find and not as strong.

Porsche 924 engine might well fit as VW based block, not sure if ‘S’ or 944 share same block/ fitting but worth looking into if you want something different. VR6 engines are pretty compact as well….. Good luck and keep us updated. James

Good luck and keep us updated. James The 924, 924S and 944 all have engines based on the old Audi system. Standard Volkswagen engines wouldnt fit them. The Porsche 924,944 engines, Volkswagen D20 and D24 diesels and all older Audi 5 cilinders (including the diesels in the T4 transporter and Volvo 850) all share the transmission bolt pattern, but its different as what VAG 4 cilinders and VR6s have. Thats the reason you see so few swapped Porsche 924s.
