Be4 Gearbox & Xu Engine Help

[yakspeed 1]

Hi There,

 

I'm in the process of acquiring a replacement gearbox for my 1.6 GTi Rally Car. After doing some research I have concluded that the ratios in a 1.9 GTi box should work pretty well, considering that I have a 4.9 CWP setup to put into the new box.

 

The problem is I am struggling to source a decent donor 1.9 BE3 box, they seem to be rarer that rocking horse poop these days, so I have been doing quite a bit of research into suitable alternatives.

 

I have found that the ratios in a 206 GTi 180 box are almost identical to those in a 1.9 GTi box, therefore I am wondering if this is a suitable alternative bearing in mind that, if my research is correct, the GTi 180 uses a BE4 box.

 

I have a KAAZ diff, and the aforementioned 4.9 CWP, to go into my new box, however I am unsure of the compatibility of a BE4 box with my engine.

 

Various threads on here talk about the differences between BE3 & BE4 boxes, however I've not found anyone using a BE4 box with the 1.6 GTi engine - is this because it can't be done?

 

If anyone can give me some information as to whether this could be done I would greatly appreciate it.

 

Many Thanks.

 

Dave.

That particular be4 bellhousing is not compatible with an xu engine, there are some which are iirc, from a dw engine.

Also the dia of the Pinion shaft is different so you cannot just swap the gears over if you where looking at that way, Mind they still fit in a XU compatible box of which I have done this on mine
