Maybe I'm going senile early but I thought the 4k was a Rabbit trans only?
Was the 4k trans delivered in any US spec Golfs 2s?

To my knowledge they where not, however the 9a/4y/aen/acd fromt he 8v gti have the exact same ratios, but the 4k final is a 3.94 instead of a 3.67. So have been tolling for just a box of 4k parts I dont need the case. I just want the final drive.


I found this on http://scirocco.org/gears/

Via Drew MacPherson (on the scirocco mailing list):

Here's a chart of transmission code and axle flanges (A2 transmissions) from the VW parts catalogue. There may be some aaplications missing, butI tried to cover most of them. I did not specify gas vs diesel, but I think as a ROT most gas transmissions in Dijifant applications (ie 100hp and up) are 100mm flanges, while most CIS and Diesel applications (85-90 hp) are 90mm flanges. The obvious exception to this that I've found are of course 85+ Sciroccos and Cabs, and some early A2 Jetta GLs. YMMV.

Bill,

James is pretty much spot on. Never seen an A2 w/ a 4K. The did come in some of the mid/late 80's Cabriolets, and possibly the 8v Scirocco IIs though.

The 4K was never factory-installed in the A2s although as Bill stated, I think it might have been installed on some Sloroccos as well as Rabbits. What's worse is that SOME of the 4K transaxles fit in the A2s and some don't - the later 4Ks came in what I call a "convertible" case that fits both the A1 and the A2. I guess you could say that transaxle "goes both ways". The way to tell is to look at the rear-most differential housing bosses - a "convertible" case has bosses that allow a bolt to pass completely thru the housing.
 
thats why its so hard to find a good 4k kids swap them into an A2 16v to make the car quick, blow out a diff bolt and finally build a tranny the right way.

Every 4K I've ever seen has the 'convertible' case.  It was the 2H (and other) boxes that don't fit in A2s

I think you're right - the 4K was the last iteration the close-ratio box in the A1 GTi, right?
