Better ratios 3rd onwards

[Richie-Van-GTi 70 2 Cars]

I'm running a xsara vts be3r box on an xu10j4rs engine in my race car. I find in particular 4th and 5th are a bit long. The gearbox is due a set of bearings, is there a better gear set I can fit in the process and what are they from? Currently on standard CWP with Quaife ATB. I do t want to sacrifice 1st and 2nd if possible as they are great as they are, even 3rd I could live with, it's mainly 4th is the issue

i think your ratios are close if not the same as a Mi16 gearbox, the 205/309 GTI ratios are shorter on 3/4/5 so it should be perfect unless you feel it's a bit short.

If you have one of the last BE3 your secondary shaft may be a BE4 one, if so you need BE4 gears from a 206 GTI.

I think the easiest way could be the gti6 6 speed box. 6 gears instead of 5 for I think the same overall gearing. Certainly when I’ve driven a gti6 they are easy to keep on the boil. If it’s a race car then the steering lock restriction should not bother you.

Fit 3-4 and 5th from a GTi6 box. Problem solved. If not, then 3-4 and 5th from a 205 GTi.

Will these fit in the be3r as I believe they are be4 internals in a be3 casing/ bell housing. 

Also would it be from a 1.6 or 1.9 box?

it seems the 6 speed can be be3r or be4,the 205 gti ratios are mostly the same on a be1/3 spline pattern.

I think the 205 GTI 3-4-5 ratios are the same 1.6-1.9. Its 1st that is different, unsure on 2nd.

be1/3 3-4 gear will only fit be3r after being modified  be4 is a different spline count.

That is what I suspected.

I do have a be3 box from a 2.0 306xsi which I could rebuild and believe is the same ratios as the be3r with the Quaife but are they weaker?

be3r is a type of box/internals, not a designation for a set of ratios.

[Richie-Van-GTi 70 2 Cars]

Yes I know that, I mean I believe the 306xsi be3 box I have is the same ratios as the xsara vts be3r box I have, I just wonder if the be4 internals of a be3r are stronger and I should justify the effort of finding better 3rd,4th,5th from a be4 or if building the be3 with easier to find gearsets is OK.

BE3R internals are strong enough for a XU10J4RS but if you can find a cheap 206 GTI BE4 then why not.
