Maybe the answer is to look at modding the gearing so that the engin will rev higher relative to the rate it turns the wheels. Not sure what gearing mods are available for the Vitara but there must be something available.

Cheers just running standard wheels with A/T tyres.

What choke size etc is the best for the 1.6 is there any intake manifold mods that can be made or tubular exhaust manifolds?

i'm not sure on what size but i have just asked on difflock they will giv you some ideas

Thank you. I will join and pot on there.

Engin tuning is a very precise science, if you decide you want more power, where do you want it, most off the shelf mods help the engin breath more freely but generaly the biggest gains are produced at the top of the rev range. You say you want more low down torque. Usually more power at the top reducess torque at the bottom. To get noticibly more low down torque your talking re-profiled cams (talk to Kent Cams) and re-shaped combustion chambers. The mods suggested on difflock will allow your engin to breath and rev better, but if youve fitted over size MT tyres the engin will still struggle to spin them - hence my suggestion of gearing mods to make it easier to use the engins designed power curve. My back ground is tuning and racing motorcycle engins - usually if you want torque over power a smaller carb and lower compression works.
