upgrading gearbox

[saxo_mike]

had a brief look into getting a different box to improve acceleration

which is the best to use

and would i get any gains from a 1.4 , 1.1 . 1.3 box ect


o also , why are rallye gearboxes so expensive

[AlexB]

rallye gearboxes are expensive as there desireable

they are lower final drive ratio but still have the bigger differential in them

1.1 boxes are shorter and have a smaller diff in
1.4 box is longer
1.3 would be an s1 rallye (the shortest fd)
then theres the 1.4 xsi box (second shortest)
then s2 rallye (bit longer)
then vts
and the vtr 1.4 and 1.5d are massively long

[saxo_mike]

hmm

what would you recommend then mate apart from the 1.3?

[AlexB]

well it depends

i really wouldnt put anything short on a vtr as its a low revving car

i would look for a vts or a 1.6 rallye or 1.6 xsi box tbh man

[saxo_mike]

k mate might just leave it then

[saxova]

or buy a 1.1 box for 20 quid. Then who cares about the smaller diff, as you only paid 20 quid.

used my 1.1 box on my vtr for 8k miles, not heard one crunch or grind in that time.
Definatley notice an improvement in acceleration. I'll be definatley buying another when this goes!

unless your a burn out freek, it'll be fine =]

Ratio wise; 3.5k rpm@70mph in 5th
4k rpm@80mph in 5th
5k rpm@100mph in 5th
6250rpm@118mph in 5th

[saxo_mike]

ahh so it revs higher at the top end so only gets to 118

sounds worth it for acceleration gains

[saxova]

definatly is worth it if your box goes.

just seems to 'blip' through the gears faster, only drops down 1k rpm when you change.

So change at 5k, straight into 4k rpm, where powerband starts.

5-4-5-4-5 ftw lol ;).
