    What grinder are you using? My 5" Makita Rattail cuts like butter. And my variable speed Metabo is like a scalpel. I'm using cut-off wheels from Benchmark Abrasives on the Makita.

    Use a black wheel or 36/40grit flap wheel to hog out material and 120/150grit to take it down to final finish. And move around. Switch side to side in your grinding. Hot metal moves around, try to keep the heat to a minimum to keep the axle straight.

    I have a Metabo 5" grinder. I use cutoff wheels and I think my flapper wheels are 80 grit.

    Welding table done. I forgot to add a pic, but I put the rear axle up on it and got a little farther on removing the old suspension mounts.

    Then I have a drivetrain update.....

    The 4 cylinder Mustang, T5 transmission, I am currently setup to use, is a weak transmission. Good for only about 240ftbls of torque, according to information I can find. The bellhousing to use the T5 is special order out of the UK, and takes a while to get, the clutch disc is special order, the pilot bearing is special, the hydraulic throwout bearing assembly is special. It is all special. And all for a weak link transmission.

    So I did some more digging. I found a company that sells a kit to use the 6 speed transmission out of an e46 M3.

    So I am picking up transmission from someone I know. It is am SMG, so I'll have to do the manual conversion. But then the kit to use that transmission uses all standard BMW clutch parts. No waiting and paying, for special parts if I have problems. The only special part is the flywheel. The kit uses an auto trans flex plate from the Saab 9000 for the starter engagement. So the flywheel is designed for that to mount to it, and to accept the BMW pilot bearing and clutch. Then everything else is BMW.

    This way I get more standard parts. And it can handle more than enough power than I will be throwing at it.

    My transmission buddy is currently gathering up the transmission and other surrounding parts that might make an install from scratch, easier. Then I'll order the install kit.

    It's a bummer that I didn't find this first. Oh well.

    What's so different about the Saab bellhousing from RWD Motorsports? The VW one I have uses an easily available A4 flywheel and pressure plate, mustang clutch, and Ford contour (Mondeo) TOB/slave. A few hundred dollars and the mustang T5 can be made to handle a bit more power and they've been around long enough that parts are actually available for them. I wouldn't hold out hope on any long term parts and support for a BMW transmission.

    Maybe look at switching to the AX15 (in 2wd fashion) for 300ftlbs or the R154 for 450ftlbs. I think the bellhousing options on these two are greater than the T5 as well?

    There is also the NV3550 in 6-speed form, at 300ftlbs as well.

    The bellhousing from RWD Motorspots is specifically designed for European version of the T5 transmission. I forgot which cars have the trans, I think it is Ford Escorts, and some TVRs.

    The only American transmission source I could find with the right input shaft length and correct diameter for the pilot bearing, was the 4 cylinder, Fox body Mustang. The World Class T5 has the wrong input shaft. And the T5 out of a 4 cylinder S-10 has the right input shaft, but the case doesn't have the right bolt pattern to bolt to the bellhousing. Unless those other transmissions you guys are suggesting have the same input shaft dimensions it won't work. And even then I will still be dealing with custom parts if I ever have to do any service.

    With this RWD Motorsports setup, the only stock parts are the Saab flywheel and pressure plate. The clutch disc was custom made by Proven Force. It uses a special pilot bearing that I would have to find a source for. The hydraulic throwout bearing assembly is a custom machined piece that came from RWD Motorsports, I don't know of a suitable aftermarket replacement. The throwout bearing itself might be a piece I can find, but the mount to get it on the transmission is custom made.

    Maybe I'm over thinking this, or what. I don't know. Maybe my application with a Saab engine is different than your VAG application, Justin. What transmission are you using on your engine?

    Here is the hydraullic throwout bearing and machined mount.

    With this new kit I can use the BMW transmission, BMW clutch, BMW pilot bearing, and BMW throwout bearing, the only custom parts are the adaptor plate and flywheel. And then with this new setup I am not limiting my horsepower and torque. The transmission will handle more than I am planning to put through it.

    Yes, the SMG is an automated manual. When I say I need to do a manual conversion I mean you have to modify the transmission to truly operate manually. There is a detent that needs to be added for a manual shifter to work properly.

    I welcome any input you guys have. There is plenty of information about a swap like this that I don't know.
