Vag 20v turbo engine RWD?
coozer - 25/12/14 at 06:07 PM

I've been looking into this for a while and there's little to had apart from an expensive adapter kit from acmeadapters, which uses a Toyota R type gearbox. (I've got an R57 in the garage)

Now since its Xmas and theres nowt on the telly I thought I'd have a deeper dig and a rethink. Any rwd vw vehicles? Well yes, the Crafter, its a badge engineered Merc Sprinter but has an R5 vw derv engine. This engine was first used in the Audi 100 according to wikipedia.

Is there a chance the bell housing pattern is the same as the 4 cylinder currently used by vw/Audi/seat??

Anybody got any of these bits lying around and can have a look, maybe take some pictures of the bell housing pattern??

Bit more digging looking at pics on the bay...

Fwd gearbox bell housing pattern looks different, BUT the a4/a6 rwd transaxle looks very similar.. Now the big Audi's with transaxles used the 1.8t so I'm more interested now!

Needs to compare some bits!!

I've found the R5 diesel was used in some volvos as well during the 90's so there may be more rwd gearboxes fit as well....

Are you sure? I thought various other investigations had shown the 1.8t had only ever been front wheel drive or 4wd?

I'm very interested in what you find out though, if there is a cheap RWD 1.8t option it would certainly be a tempting engine conversion for me!


big_wasa - 25/12/14 at 07:45 PM

Yep, will be very clever if you can do it with oem bits.

I think a Mazda box is the way to go with an adapter plate. cheap and plentiful.

No some of the a4's and a6's used the 1.8t and the 1.9tdi which are the same I think...


samjc - 25/12/14 at 08:06 PM

Someone at work recently had a 1.8t audi a4 b6 before wrapping it round a lamp post on a slippy road. Hes excuse was it was his first rwd car. Not looked deeply into it but could ask on audi forum for you.


coozer - 25/12/14 at 08:15 PM

Bad excuse, its fwd!


samjc - 25/12/14 at 08:32 PM

Posted on a fb forum and a fella says hes modified a AWD box to be rear wheel drive for a kit car a couple of years back. If its a route youd like to try i can get his details for you.
I thort it was a bad excuse but never looked into it haha.


Slimy38 - 25/12/14 at 09:00 PM

I kind of follow what you're getting at, but if you're using a diesel transmission to get the RWD won't you have to do something with the ratios?


tegwin - 25/12/14 at 11:01 PM

The passat 1.8t engine I think is nothing like the 1.8t engine from the seat Leon cupra/golf.... Engine code BAM is what you want.... In standard form you can map them to nearly 250hp or so.... Hybred turbo and injectors will see considerably more...

Pretty sure it's not a direct fit onto the Audi transaxle....I have seen an alloy adapter to mate it to a Mazda box though....


Sierra - 25/12/14 at 11:47 PM

Hr engineering built this a while back so might be worth speaking to them. They've built some right beasts.

The scooby boys do this for drifting, thus locks the front diff I think to power is transmitted just to the rear. Loads on the net on this and some conversion kits available.


Volvorsport - 26/12/14 at 10:52 AM

Not sure if the bellhousing is the same as the 5cyl diesel in the transporter, it may be possible to fit the Volvo diesel m90 onto it.

if you can fit an m90 diesel, may as well fit the petrol with an engine on it .......


nye - 26/12/14 at 02:55 PM

I'm currently attempting to put one in to a luego velocity.... The 1.8t in golf/Leon etc is practically the same engine with the only differences being some have external waterpumps and also port sizing on the head.... Bellhousing patterns are the same, the route I'm going is building a custom bellhousing as I have adapted the type 9 bellhousing to the engine but struggling to locate the starter without having to move the engine further forward which is something I done want to do! I plan on using a passat tdi single mass flywheel and sorting out a clutch combination to suit. Any question on it just ask as all the parts are accessable so can measure anything needed!

I decided to go for this engine choice as fancied the challenge and had a spare 1.8t engine taking up room in the garage....


nye - 26/12/14 at 03:00 PM

Also closest I got with oem gearbox was an lt35 1.9tdi which Is rwd and I believe will is the same bellhousing??? My understanding is 4 cylinder vw engines have the same bellhousing but they are different to 5,6 cyclinder engines. I chose against that gearbox though as looks to be too big for a seven!


INDY BIRD - 26/12/14 at 03:16 PM

Scary thing is I was told that he engineering car they spent near 100k on it ouch how they spent that much I'll never know

Best of luck

yes, but it sits on a 15-20 degree angle.
I had a 2.5 TDi mounted to a mid engine transaxle breifly, then decided to go 2.7tt

volvo diesel box then should fit, but they never made a RWD one as far as i know

Maybe possible to use a 01E gearbox with the front output shafts disabled? I know its not ideal, and people have tried doing it the other way (disabling the rear output) with varying success

Or how about torque tube setup, use a mid engine transaxle in the rear?


Volvorsport - 26/12/14 at 08:06 PM

Volvo 940 Turbo diesel is RWD.....

they have 6 cylinder transporter engine 2.4 Td

wether that translates to 1.9 tdi I don't know


43655 - 26/12/14 at 09:15 PM

940 is volvo engine though, the 2.5 TDi used in the V70 (& 850) is an Audi engine, and the gearbox has been made to suit.
transporter 2.4 is a crappy NA inline 5, but still FWD


Volvorsport - 26/12/14 at 09:44 PM

No the Volvo Turbo diesel is the vw 6 cylinder diesel engine and is Rwd

Hi guys how do donkervert do it probs spelt it wrong but you get the gist

They use their own bellhousing, which won't be cheap (even if you could buy one).


i_froloshki - 28/12/14 at 06:10 PM

Gents,
is there a drawing or cad or something for the 1.8T VAG engine bolt patern so an adapter plate can be cnc produced? I managed to find some mt75 drawings that will be ok for the gearbox side of the plate, but i am not able to find for the engine side. I know the guys from Alphax are making a kit but it is way above my budget so ....


gaz_gaz - 28/12/14 at 06:40 PM

Why don't you approach Quaiffe, Xtrac or Hewland and ask them if they'd be interested in producing a cast bell housing.
I know 1 of the companies would probably get involved in the project for an initial order of around 10 parts.
can't imagine it would be difficult to drum up interest in a group buy depending on cost!

Mostly Di-noc by the look of it


FlansS14 - 29/12/14 at 04:58 PM

I knew I had these somewhere......









I looked into the Vag 1.8T before deciding the Nissan option was cheaper and better IMO.

WOW That's UGLY!! 360BHP with that turbo... It must be about to go BOOM, Mind you the valves or rods will go before it

Slightly off topic, but I found this pic of a custom bellhousing, and the work really appealed to me...

360 bhp with a stock manifold is unheard of, and hybrids have a habit of blowing apart as they are not designed to take such power.
To get 360 bhp from these engines with reliability you need a good manifold with an IHI VF30 or bigger, even a Garret GT28RS. Also people think these engines are built proof. Well the A4 is not as strong as a TT (BAM) lump to start and even BAM lumps over 300bhp are advised to fit updated rods and valves.

IMO Unless that guy has missed off lots of spec details, your buying a ticking time bomb.


FlansS14 - 30/12/14 at 08:45 AM

That steel bell housing is a work of Art!!

We built a bell housing to convert a ford 1.6 sigma to a type 9. Just need an old FWD box and cut of all the crap, find a suitable RWD box with the same size clutch plate.

The measure your nose length, weld a base plate and get it machined back.

It sounds simple... But it's not, 1mm out would knacker the box/bearings.

Also need to find a box with removable bell housing, type 9 just would not take the power


coyoteboy - 30/12/14 at 11:40 AM

I have an 01E FWD trans axle (not 4wd, not disabled either) and this is what I'm bolting to my audi ABZ V8. I may have a hole layout somewhere but I think you're looking elsewhere as you're wanting front engine rwd. Some things to note if you do find a 4wd box to disable the fronts, the rear output internals may not be sized to take the torque alone.


FlansS14 - 30/12/14 at 12:45 PM

There is a chap called Scoff that runs EFI Tuning. He makes bellhousing convertions from Renault 172/182 engines to Golf 02j/02m Boxes. This is the same bolt pattern. He has the diagrams if you go down that route


i_froloshki - 1/1/15 at 04:50 PM

Where is this guy, where can i send him the question?


i_froloshki - 5/1/15 at 08:41 PM

Gents, can anybody give a parts lits for this conversion from 1.8T to Mt75 - flywheel, clutch, starter motor etc?
Thanks
yavor


i_froloshki - 22/1/15 at 07:32 PM

Well... i have to go to the familiar zetec option then....


i_froloshki - 31/5/20 at 07:10 PM

We are on the way to make the adapter plate from 1.8T engine to MT75. I am not sure how much it will be, still waiting for the CNC offer, but i will let you know, so if you need one - post me a U2u so we can make a bulk order and reduce the price.
Regards
Yavor


ettore bugatti - 31/5/20 at 07:22 PM

Has http://www.rwdmotorsport.com/bellhousings.html been mentioned before?


i_froloshki - 31/5/20 at 08:03 PM

Yeees, but mt75 doesn't have a bellhousing so no options... Here in Bulgaria is a bit difficult to find t5, so mt75 is the best option for rwd. Well, bmw is also available, but the book is ford based so....


i_froloshki - 1/6/20 at 07:47 AM

CAD (cardboard aid design) mock up of the adapter plate. I managed to source the drawings of the Mt75 and VAG 1.8T bolt pattern for the gearbox side, we checked them and we send it for real CAD drawings. We had to rotate 8 degrees the engine to avoid 2 bolt holes partial match, but the engine is rotated a bit anyways, so i hope it will be ok. We will use Audi A4 1.9 TDI 90HP solid flywheel and pressure plate (228mm) and a ford friction plate (still windering which one). The starter will be on the engine side, goes below the turbo, probably will be also 1.9 TDI audi/vw.

I'm swapping my Westfield with the 1.8T engine, you can find all the info I've got here: http://locostbuilders.co.uk/forum/9/viewthread.php?tid=215914
My car has already got a Type9 gearbox so I'm going to use the RWD Motorsport bellhousing. The MT75 is generally cheaper but gear ratio are awful for our cars, first gear is very short and second gear pretty long instead. The T9 can be rebuilt with a variety of gear ratios that better suit our lightweight cars (but they don't come cheaper unfortunately).


i_froloshki - 1/6/20 at 02:51 PM

Hi, yes, i have read your build. The MT75 is not very convenient, but with my first car we have played with the diff ratio (4.17 scorpio) and it was ok.
As i mentioned the MT75 is available here, so i have no choice.

Oh absolutely. As I said, I'm going to use the T9 because that's what my car is already running, so I can avoid a ton of chassis mods and just change the bellhousing and bolt up the engine.
The MT75 is still used on a number of Seven with the VAG engine, look for HKT on Youtube
I think even Donkervoort used it in the past with the 1.8T, but I may be wrong
