First pic is of VR6 starter next to Porsche unit (with snout)

Next is of VR6 starter w/bellhousing...if you look closely, you can see that the "snout" for the VR unit is built into the bellhousing, enabling the starter to be installed w/solenoid either up or down, as required.

The VR starter is installed from the TT side of the bellhousing....

Sounds great and you seem to have it all under control. I am not a big fan of the motor stock as I think it sounds really pissy, but I had a friend who put a s/c on his and it made things interesting. Forced induction is the way to go. Plenty of available performance parts too.
If I was to go away from the i4 but stay under the family umbrella, I like the idea of the i5.

Look forward to seeing your progress.

Forgot pic, lol...

Are we talking about the same motor, lol? Although I have to admit, when they've got the stock exhaust system, they don't sound like much.
There is a guy who did a 20V inline 5 cylinder...

Agree on forced induction; though the 12v engines are very torquey in their N/A form, F.I. REALLY wakes them up, and because of the compact structure of the block and crank, 400 hp is not by any means unreasonable on stock internals.

After two weeks, progress...part of what was slowing me down, was getting the carpet out of the car for the purpose of (a) determining the areas necessary to cut on the TT tunnel for the necessary starter clearance for the VR6 bellhousing, and (b) to pressure wash and dry the carpeting. To accomplish that, it was necessary to remove the throttle pedal, but moisture in the footwell over the years had badly corroded the studs anchoring the throttle pedal assembly to the floor. After reading earlier posts here, I realized that this was an area I needed to be careful in, to avoid unnecessary headaches later on. I first soaked the studs and nuts with SiliKroil for two days, and attempted to break loose the nuts---that was a no go. I kept spraying every couple of days, and tonight they finally came loose. I immediately chased the threads on the studs with a metric thread cutter to clean them up and ensure that reassembly would not result in broken studs and the aforementioned headaches. Also going to put some grey slime (Permatex antiseize compound) on them as well.

Please finish this and keep us updated.

DID you have to cut the VW bellhousing or is that the way it is??

Vonov · 06-07-2009, 04:10 PM

The short answer is yes. The VW bellhousing is part of the FWD transmission case...to obtain a usable bellhousing for a VR6 longitudinal installation, you have to split the case on a Passat manual gearbox (preferably one which already has bad gears; when one of those units loses the shear pin and eats the side of the case, that's an ideal candidate, because that case is scrap anyway at that point) and remove the guts. For our purposes here, the bellhousing is carefully cut away from the main part of the trans case, being careful not to compromise the structure of the bellhousing itself. In the image below, you can see what was cut away from the bellhousing (lighter grey) and what went where in relation to the original case.

And I most emphatically plan to finish this (really hate when someone tells me, "it can't be done")...

Here's another shot, which more clearly illustrates exactly what's going on...

Potomac-Greg · 06-07-2009, 07:58 PM

Good luck to you! I hope that you clear a lot of the underbrush so we can get someone to tackle a VW/Audi 2.0T conversion!

Vonov · 06-07-2009, 08:10 PM

Yes, this should be fairly similar to what would be required there...or, for that matter (***blasphemy alert***) a TDI...

I'm genuinely interested to see the finished product (as well as a detailed write-up of the process). As you no doubt know, photos of this swap in particular are going to be etched deeply in the subconscious of the second generation of 944 owners, like me.

Take lots of photos!

You have my word. As for detailed writeup, I thought this thread was it? I may get more detailed when we get to the electronics portion of this.
