I bought a couple of S4C Gearbox's from Honda New Zealand because they were brand new and they were rediculously cheap. They seem to be from the New Zealand EK4 however they have ratio's closer to the LS gearbox's.

Anyhow after 10,000km and one day at the drags I think I have killed my 3rd gear syncro (crunching into 3rd).

Is there anyway to find out if this is really a LS gearbox or just a weirdly spec'ed B16 box?

I was also wondering what you guys are running for gearbox's (I have 224KW atw and I am already breaking stuff)??
