The Project Pad

I need a 60-2 input for my ECU, and I was wondering what everyone's preferred method is. I'm a bit leery of using the front pulley with a VR sensor bracket on it. Magnetic interference from the alternator as well as the high potential for damage come to mind. I've gathered that 2.7t flywheels will work, as long as the proper pressure plate is used.

ideas?

flywheel mounted is my favorite (aka stock 2.7t style). large diameter and nice solid mounting of the sensor on the trans means its pretty well gauranteed to be a good signal.

another good choice is the factory vw rear main seal trigger kit, which is hall sensor based. the hardest part of that kit is the moutning and running of the cable. usually you have to drill a small hole in the block to pass the cable through.

Is a 2.7t flywheel something that fits? I sat one on top of my 7A FW, and the bolt holes appear to match up.

I assume factory trigger angle is 60deg on those as well?

Oh great, now there's another option for me to think about... I have the 034 crankwheel and balked at mounting onto my (MC2) damper because it doesn't seem to fit well. It'd be a press fit but it seems like the outer ring of the damper would rub against it when it was doing its job of damping. Plus, they were less than forthcoming as to what crank sensors the bracket was designed to fit.

DIYAutotune sells the same VR sensor for less.

I don't want to use that. The bracket looks like it was made for some OEM application and I wanted to know what application it was for. I like being able to define my suppliers and also to know how to get one quickly if it craps out 30 miles from East Bumfarkistan.

Had the time to actually work on the engine tonight! Made a piston stop, mount harmonic damper, mount VR bracket, rotate this way and mark, rotate that way and mark, in between the two is TDC, good good good...

Take damper back off, get 034-sourced 60-2 wheel, and huh?? There is no way for the wheel to work on the damper. The center diameter is too large to fit the inner hub. Maybe if I machined the hub down so I could slip fit a ring over it that the damper would fit to, it would work (and this may be the route I go) but I was under the impression that it was supposed to fit and zap zap with some weld and you're done.

Buying the prebuilt damper was not an option because I can't see buying a new damper when I have a bunch of good ones, and anyways I don't have a 20v.
