haha yh it took a little while to get used to but it pulled great in any gear tbh it was quite good on fuel too tbf as i got used to coasting in it as you didnt really need a throttle to get it to 40mph

im running a cavaliers f18, no problems and it gets some stick! got a quaiffe atb diff in there to.
a vectra b f18 would give better accelaration due to lower ratio final drive.

bit of a odd questiom for you dave but if you cruised at 3000rpm in fifth what speed would you be doing then on your f18?

yes, vectras run on larger wheels than other vauxhalls with f18.
using f23 from a vectra in my corsa c z22se, 70mph is around 3200rpm in 5th. not so good for cruising but get there quick enough.

i think i read somewhere that there are two different ratios aswell, i think the individual gear ratios are different but the final drive ends up the same? unless the info i read was wrong :/
