4.3:1 in an NA6

Postby flycasta » Fri May 16, 2008 10:09 pm

What diff ratios did the NA6 have?


I just got a 4.30:1 gear set from Japan that was supposed for an NB8 but it is smaller and must be from the NA6 But I cant find any info of what ratios were available. I am wondering if it is actually from an MX5 at all.

Thanks Duane

Thanks Guys.

No the Japanese NB had the 4.30:1 in them and that is what this was supposed to be but this is smaller than the normal NB8 crown wheel so I am assuming it is an NA6 crown wheel.

Some jap spec NBs did have 4:3 these were the NRA version I believe. Thats what my diff is, it is the same size as any other na8/nb.

It sounds much like you have a na6 crownwheel.
