Rethinking the starter... I wonder just how much it would cost to have a 944T flywheel made with the right depth and drilling for the volks motor.
Hah! too late now...
Bonus savings using an ebay GTI light flywheel/clutch kit. Will need to have a disc made for the final install. The Ranger truck disc is fine for mock up, but I don't expect it to hold the HP.

Just buy that Chinese stainless tubular mani and modify it like MWR did. I had that manifold in my A4 B5 1.8T over 10.000km and and it worked fine. Everyone says they crack but I believe that they won't if you have good support for the turbo. There are models which crack but that ain't one of those. Just cut the flange out of it, weld couple of curves and there you have it. That manifold sits quite close to the head.

How was it with RX-8 Disc? If I don't remember wrong it also has 240mm disc with right splines.

I was leaning away from a custom flywheel as well. I wanted to use the vr6 flywheel, PP, TOB and fork, along with a modified vr6 bellhousing (or a custom one). Then look through catalogs for the right pilot bearing and clutch disc.

For the starter, I thought about a BAS from a GM/Chevy. Basically it's an alternator/generator/starter. Advantage, it makes the car a hybrid, so maybe I could get smog exemption. LOL in my dreams...

The 968 6MT starter has a long nose so it could bolt to a 944 bellhousing and extend through a bellhousing adapter to reach the flywheel. Maybe the starter boss could be machined or shimmed to match the starter to the flywheel.

Thanks for the tip! I'm OK with my solution, but that's worth a try for the next time around.
The GTI ring gear is at least similar, if not the same as the 944T, just mounted on the flywheel instead of the PP.
968 starter might be just the ticket.
The GTI clutch is 228mm (~9")... I'll need to have one made. Porsche spline count and diameter are the same as an RX8 or Ford/Mazda small truck

There is one pricey but well working combination. Clutchmasters has bolt on set for this setup and it has steel flywheel, 240mm clutch and pressure plate. Should hold over 500nm of torque. That flywheel has S4/RS4 design so you could probably buy just the flywheel and use RS4 pressure plate with suitable disc.

Got the Gram's intake manifold today... learned something too: It won't clear the hood!
Looking closely at the MWR pix, I suspect they stand the motor up a little from the stock 944 angle.
Seems a little closer to the booster in their pix.
3 options:
Hood bulge
Machine the manifold at an angle (or make an angle adapter) to lay it down a little
Redo my adapter plate to stand the motor up.
3rd option is the neatest, also allows more room down the right side for the turbo.
B*tch!

Angle adapter, definitely.

Nowanker 12-21-2017 11:20 PM

Tempted to redo the adapter... easy change in the autocad file, but burns $100 worth of aluminum and another $200 at the machine shop. "R&D cost"
The extra room on the other side for the turbo might make it worthwhile.
%$#@!.
And that's about all I have to say about that...

V2Rocket 12-21-2017 11:22 PM

how much hood interference?
could you shave the bottom of the engine mount arms to lower the whole engine vertically?

Nowanker 12-21-2017 11:55 PM

Prob 1 1/2"? Don't want to drop the engine too much on account of the oil pan clearance.
Thought of scrapping $300 pisses me off big time... but I do like to do things the right way.
Character flaw.

V2Rocket 12-22-2017 12:21 AM

yikes...
that intake that much better than the stock B5 :p

Nowanker 12-22-2017 05:58 PM

Stock Audi A4 man puts the throttle body into the master cyl,
Stock GTI man stands up taller still...

V2Rocket 12-22-2017 06:36 PM

?? this one? passat/A4 90s/00s

if you're up for an experiment (something i want to try but dont have an excuse to yet), the brake MC from a current Subaru Outback (2014?+) has the same bore as the 944 and the flange looks like it could adapt (or take an adapter) to fit the 944 booster.
but it's about 3" shorter overall than the 944 MC.

Hmmmm.
Still tempted to stand the engine more upright for added turbo clearance.
