[trent1542]

possible? who's done it? Are the VW VR6's aircooled or watercooled?

That G60 looks like a lot of work. did you hook it up to the passat tranny? does that passat tranny fit in the 914 pretty good? looks like it does.

what did you do about the linkage? and do the dogbones hook right up? i would image they do.

and what year(s) passat trannys?

The B5 (1998) and newer passats used the longitudinal FWD tranny. It's shared with the audis from the same period. The bell housing has bolt patterns for almost all the VW/Audi engines with the exception of the VR6 and R32 engines.

The transmission is a no brainer IF you keep an eye out for one with 100mm output flanges. The VW/Audi FWD longitudinal trannies come with three different output flanges ranging from 100mm to 114mm. The 100mm flanges will bolt directly to 911 axles/CVs. Obviously, this requires 911 hubs. I'm currently working with a machine shop on adapters for the larger flanges.

The transmission mounts must be fabricated. Unlike the 914 transmission, they're not integral to the case so this isn't that big a deal.

The linkage is pretty easy too. It's a cable shifter transmission and functionally identical to the tranny in the Boxster. Just grab the cables/shifter out of a boxster and off you go.

That leaves the clutch, it's hydrologic. The slickest solution I've found is the hydrolic pedal set from Willwood.

If you start putting money next to each of these things, you can see it's not tough mechanically, but it ain't cheep either.

does the passat tranny shift better than the 915 trans? its newer technology, i would think so. and does the passat trans require a computer to shift that tranny?

the 901 trans is so ancient. i think a nice shift would make any 914 any engine a dream.

The trani shifts like a boxster trani, the guts are essentially the same.

I drive one daily (actually I did, till the turbo went), Trani is one of the smoother portions of the car..
