Top 5 Modifications

well the 5th gear set I have fitted is a .80(original is .89) you can also fit a .75 from a chc/chd diesel gearbox but I find they give to big a gap between 4th/5th. the mk3 gti 8v also has a .80 5th gear set but there is a slight difference in the retaining circlip which can be overcome easily with a shim iirc. gear set can be changed in situ if you remove front engine mount and lower engine and box down about an inch. the gear set I have was out of a mk3 golf 1.4. cant remember the code but I will try and find it.

Great info, thanks!

How much does it change cruising revs? I current cruise 80@4k rpm.

hey no probs man the gearbox code was cza but there is probably a few different boxes with the .80 ratio. at 4krpm now my car is doing 92mph. 70mph at 3krpm. its quite a noticeable change to the cars cruising ability.

Well, sounds like a future mod for me then

Put the 1Y CHC 5th gear in from the mk3 diesel. Straight swap and all the info you'll need is on brokevw. Did that with mine and her top speed now is just shy of 130!!
(Not that I've pushed her that hard ;-) ..... and yes good mpg for motorway cruising and will just about pull you along at 40mph when in suburbia.
