Evening,

wondering if someone can help me?

I currently run a 2.0 blacktop in the ka with the original endura gearbox and 3rd is hitting 110 and 4th I haven't reached the end of yet on a trackday and its not exactly slow getting to to those speeds but pointlessly high gearbox ratios so thinking the st150 ratios would be more suited.

Just need to know what I need to put st150 internals into a ka gearbox? is it just the gearkit itself? or is anything else needed?

Or can someone suggest a better gearbox? I had a sportka a few years back but that topped out at 110/115 so don't think its quite long enough as although I have another 1000rpm to play with I don't want to be bouncing off the limiter in 5th unless 5th will top out close to 135/140 on 15's at 7500rpm?

Thanks,
Rich
