MWR now selling components.
Well aint that a b*tch.
I'm already well along with mine. Spent a zillion hours on the dimensions for the adapter plate, a few hundred $$ having it CNC'd, found I needed to adjust the engine angle for intake man clearance.
Just finished the SECOND prototype plate... think I got it right this time.
$1700 is dirt cheap.

especially considering they give you a billet FW ready for standard 944 clutch parts.
nice!

related note, do you think the golf/beetle FWD intake manifolds would clear the 944 brake parts? they are end-feed unlike the sort of "side feed" B5 passat/Audi type intake.

Played with intake manifolds today. The 034 Motorsport mani that MWR (and I) use just contacts the OE booster. Might be possible to grind some clearance into it, but I'm going with a dual master manual brake setup anyway.
That mani interferes with the hood by 1/2" at the throttle body flange... options are to lower the F crossmember a tad, or bulge the hood. I'm leaning toward the hood bulge, but I'm pretty sure MWR drops the subframe (or modifies/builds a new one for lower engine mounting?).
No way either the Passat or GTI mani's fit with the stock booster. They also contact the firewall, but do clear the hood.

OP: Sorry for hijacking your thread. Good luck with the build!
Sounds like an awesome choice for a higher HP engine.

Maybe we should keep this thread 07K (2.5L 5 cyl) related? Thereĺs another thread for 1.8t stuff.

Agreed.
Was planning on starting a fresh one, once I had enough progress to show.
Good luck!

Here's a quick progress update on the engine mount design. I also just received the SPEC flywheel and clutch setup, so I can now finalize the Quick Time bellhousing design and get the prototypes going.

The turbo shown in a Garrett G25-660 reverse rotation. I believe all of Garrett's reverse rotation turbos will the fit the space. I think the biggest option is the GTX-3582, which is good for up to 850 hp. I'm personally only shooting for about 500 hp for now, so the G25-660 is a better match for that.





Engine mount stresses shown with 1000 lb compression load applied. This is approximately 1.5 times the load that would occur with 500 ft-lb of engine torque plus a 3G engine weight bump load (engine weight split half and half between the two engine mounts). The driver's side engine mount is loaded a lot less because engine torque is in the opposite direction from the compression load of the engine weight, so they cancel each other out to some extent.

for engine mount pucks in that form check out older Jaguar inline 6 mounts.

Thanks, got em already from here: https://www.carbuildersolutions.com/...ox-mount-large. Website says: "We used these very successfully on V12 Ferrari engine installations" so I think they should be strong enough. If not, there are lots of other similar mounts out there, or it may even be ok to solid mount it like most LS swap guys do.

Bellhousing design is basically done... sent the CAD files to Quick Time for review. Here are some renderings:

Thanks! It was a lot of work. I'm so glad I bought all of the mating components to test fit... the flywheel, clutch, release bearing, starter, etc. When I mocked all those things up, I found a few surprises and had to make some changes.

Here are some more renderings, showing the 3-piece cross member and the engine mounts. I hope to send these designs out to get prototype pieces made very soon.

WOW that looks cool!

here's a thought though - maybe incorporate a round metal tube on the engine mount or the xmember as a sort of "protector sleeve" that the turbo elbow fits inside.

That cross member and engine mount setup look very nicely done! I definitely know what is going to go in my S2 engine bay now... I have a few questions as far as mating it to the rest of the car though. Would I need to keep the stock engine wiring harness for any reason or will the 07K harness and VEMS be all that I need? Does the G25 series turbo you are using have an internal wastegate or would you run an external wastegate like the 951 does? I have a Tial 38 and adapter plates from my turbo car and was going to sell it if it did not work in this application. Also please put me down as a definite for the bellhousing group buy if not too late.

Hopefully they won't have too much vibration. Something to consider would be the ability to use OE mounts so people could change them out to different density options to suit their tolerance of vibrations.
