fantastic work!

A team in the NH loudon lemons race had been running a 1.8T passat engine in their 944. i think it was 2013/14/15. They had a company that was upstate NH or ME that specialized in engine swapping.

Thinking about that swap today and I'm pretty sure that they said a bell housing from a 931 was almost a direct adapter fit

It would be great if this were made into a kit, there are loads of half-dead Passats out there that can be picked up for a song and that chart suggests a large weight savings is possible:

If the stock ECU could be used it is very tuneable and has a great MAF/MAP system with integrated knock-aware boost control. Oil sludge is a problem with the 1.8T however.

I agree, but it seems like MWR is only interested in selling turn-key cars or doing the swap in house. That site has been up for quite some time without ever listing a price or even saying they're available for purchase.

They used a 944 bellhousing with a simple adapter plate.
The 931 bellhousing doesn't work for the 1.8T engine, they only share one bolt. 931 has basically the I5 pattern which is different from the I4 one.

Red bolts are 1.8T (or 07k in my case), yellow are 931 bellhousing bolts.

Any news about this project? I'm about to do the same thing. Plan is to cut bell housing from A4 B5 gearbox and then just weld suitable adapter in the bottom of it. I would also like to avoid chassis modifications.

Wicked build!

How was the fitment of the SPA exhaust manifold? They seem to be decently priced but haven't heard much about them. Are you running an external wastegate? Is there room to even run one with that manifold without clearance issues with the strut tower?

What turbo do you have mounted to the manifold? I didn't see the details but maybe I missed a post.

I also have a 1.8t AEB that will be swapped in to my 924 next year (hopefully).

OP has been gone for over a year.

all these f_cking astronauts.... we've been hearing about these phantom vw +/- Audi projects that never get completed for going on 2 decades now....

enough with the insanity....

that ought to tell you a lot about the superiority of running the massive GM 4.0 stroker H3 Hummer i-5 turbo.

or GM v8...

and who could blame you?

because all you really wanted was f_cking VW or Audi to build a god-damned large displacement 5 cylinder crate engine all along ....so the proletariat on 5 continents could drive a good are with a decent engine for a 2nd go-round....

yeah, a big f_cking crate motor like all those wacky Americans have.

yeah, it's still Hotrodding 101: there's no substitute for cubic inches.

dont know of anybody who's put an Atlas (family of that H3 I5) in a 944...would be awesome but its a tall motor...

how long did your swap take to pull off, with a commercially available kit?

odurandina

a while... but it's coming along.

You'll get to see some things sorted out in a few weeks.

driving 5 1/2 inches over the pavement is fun.

but, when you ride that close to the tarmac for tens of thousands of miles, stuff happens. whether you're running a Carrera GT, TVR or 968, inevitably, you hit something, and you're a daisy if you do; sh_t contorts into shapes where it was never meant to go ....and repairs sometimes will need to be made.

I didn't knew that somebody was actually still working with this idea. I'm about to get my bellhousing back from the workshop. My friend is doing the milling and welding.

I have garret 54/57mm billet turbo with T3 flange and I'm going to use external wastegate. I haven't decided yet what to do with the exhaust manifold. Spa-turbo twin scroll manifold could be good if there is enough room for it. On the other hand i would like to weld unequal length exhaust manifold with sip-on merge collector... Just like MWR did in their +400hp models. One alternative is to modify this manifold for t3 flange: https://www.ebay.ie/itm/VW-Passat-1-...item2386a39f6c

I had that in my A4 B5 and I worked fine. No cracks and spooling was fast. MWR is using modified version of that too. At least it looks like it.

Brockoli

Not sure if there will be enough room with that ebay manifold for a bigger turbo. It looks like MWR uses a tubular manifold like you mentioned that puts the turbo out front of the engine. I have asked a couple of people that have successfully completed this swap how much room there is in between the stock KO3 and the frame rail but havent heard back yet.

One swap that I have looked at had the frame rail modified to make room for the stock turbo and stock manifold. I think that person mentioned that they had a different engine orientation (engine rotated towards the passenger side frame rail) which caused the interference.

The MWR cars with the stock turbo locations look to be running the stock KO3 turbos or something close to that size.

I also looked at the spa twin scroll manifold but I think the waste gate pipe will interfere with the strut tower. This is only a guess at this point.

I was curious at the turbo size that was used in this build since it looks big and looks to fit but is close to the strut tower.

sledgehammer

I'm going to relocate the turbo anyway so the size really isn't a problem. There will be plenty of space in the front of the engine.
