ive got a '90 G astra sri and the 5th gear on it is the same ratio as 4th on my old 1.3
i want a less fuel-consuming gear for high speeds but dont wanna lose the close ratios for fast acceleration. this is why i think a 6 speed be in order. the 6th gear doesnt have to be quite as long a ratio as my old 5th gear but still better than my current 5th. (u still wiv me...!)
is there a standard vauxhall item than will be a straight swap? what are the gear ratio's on these?? or will an after market 'box be better??
