right people sorry about keep posting threads lol but i have just ripped out my 4 speed gearbox and it now has a 5 speed g40 gear box fits perfectly and everything :)
wil this imporve my cars performance a little Lol !!!!!
"lol" is a bit over used there mate haha.
Clearly adding the correct gb to the engine will improve the performance. Not as much as if you had used a gt box then changed to an atv one but still you get an extra gear and more economy, matched with the correct power in each gear. I've heard 4 speeds using in drag polos though.
yaeh i know mate but this gear box was only 85 with gear likages and lever :/ soo yes more econ but not as much power Lol
