Ok got a 20xe engine waiting to go into my car, but just wondering what peoples opinons are on changing the current f20 gearbox i have to a f16 ???

as some people say f16 is better due to closer ratios so better accelartion and some say ratio is no difference and f20 will go further

so this leaves me not knowing what to do???

any replys and useful information is very greatful

F16 usually has shorter ratios but isn't as strong.

F20 with longer ratios will technically give you better top speed but this depends on engine power and whether you want to do 140mph in a Corsa.

f20 is better option,however cant see the point in doing over 100mph on british motorways, keep it on the track

depends what you want it for.
if you want acceleration go for a f16 out of a cavvy sri which has closer ratios than the likes of a 2l gls cavvy. go for the f20 if you want top end speed.
iv got the f16 on mine, but i just use it for 1/4 mile days,my engine kicks out 212bhp and iv had no problems so far with it.

cheers people for your replies much appreciated

i think i may stick with f20 for now just solely due to me already having this gearbox!

thanks again
