In the process of building an engine for the track.
I could do with some information from anyone who has performed the modification as per the title.
I reckon it's the thing to do as I get overtaken on the starts when I go for 2nd,it's like I park it.... and that's been starting from P3.
What exactly do I have to change,do I just drop in the whole NC30 transmission?
Do I need the NC30 shift drum and forks?
I'm running an NC35 engine in an NC30 chassis so the different length NC30 countershaft is not a problem.
I have searched but found nothing to answer my questions.
Cheers.

It is the first gear that is the big difference.. I reckon if you have the whole lot you would be sorted.

There are threads on here about it...am sure there are.

As CMSMJ1 says drop the the whole gearset in.
