Ok, this is mainly for the junior sedan part of the site but anyway it is news worth publishing.

 

The DIFF Ratios for ALL junior sedans are OPEN same with GEARBOX ratios also

any HEAD bolting onto the original 3K Block without mods is now consitored LEGAL.

If you need some links and/ or information about this matter.

This site is the formal NASR site.

There's a link there to a guy named Peter Harris in Alice Springs and he'll give some info if ya need it.

woopah get them 2k heads on ther brudas.

 

cheers

That helps out f@$king heaps man, I wouldn't have known about this if I hadn't been told....

 

Now I gotta work out what the go is with heads (Can I fit a K, 4k or 5k head to up the compression on the 3k?), and I think I might just remember something about Hayabusa pistons bolting onto the K motor rods and being the right width etc....

 

Can any of the members give me any advice on this?

 

Cheers,

Dan.

Yeah any help from the rollaclub community on heads that bolt onto a 3K would be appreciated.

2k head will give you good compression on a 3k

I thought that there was no such thing as a 2K, and that there was only a K, 3K, 4K, 5K or 7K... But yeah, if there was a 2k it would be a good alternative.. if i could get my hands on one.
