Hi mate i have an f18 gearbox if intrested came out of an astar gsi 1800 mech driven

no point mate.. ratios are exactly the same... all cavalier close ratio boxes have the same ratios... the exact tooth counts on cogs varies.. but the end ratios are the same.

all you would be doing is swapping a newer box for an older one... with likely more miles.. (plus ive never found F20's to be as smooth to use)

in each gear at each RPM you will be doing the exact same speed with both boxes... so its just not worth it

he already has one in his car... why would he want another one?
he's just asking if its worth "upgrading" to an F20... which its not.

Well u dont know his gearbox may be fecked may aswell offer him one you never know till you try

lol... i think from what he's writen that he was just trying to work out if an F20 was better in some way.

id have the F18 over the F20 any day... smoother action.. newer and pretty much as strong (as long as it aint a vectra one)

 

[jaysri]

thanks guys thats all i needed to know cheers

 

[ruffday]

So is the F18 a direct replacement for the F20 box?

 

[jays-cally]

i have a calibra i think it has the f20 box in it and its f**ked so could i fit an f18 box in it then,my engine is the c20xe (redtop engine)

cheers

I may have one, where are you located.?

 

[shrink]

i see no reason not to swap an F20 for an F18 in a calibra.... its 6 and half a dozen.. same ratios... and yes the F20 "was" a stronger box.. but age and mileage probably makes the F18 a safer bet

you will however lose the inspection plate making clutch changes more expensive.

Exactly.

 

[shrink]

yeah but if its a later redtop it'll have pot flywheel anyway and clutch job cant be done through the plate.. so its as little as makes no difference.
