speedway_rolla Posted June 11, 2006 Report Share Posted June 11, 2006 (edited) 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. http://www.speedwaysedans.com/default.asp?...elease&Id=19366 There's a link there to a guy named Peter Harris in Alice Springs and he'll give some info if ya need it. Keep racing my brotheriens :thumbsup: Edited June 12, 2006 by speedway_rolla Quote Link to comment Share on other sites More sharing options...

Dan Posted June 12, 2006 Report Share Posted June 12, 2006 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. Quote Link to comment Share on other sites More sharing options...
speedway_rolla Posted June 13, 2006 Author Report Share Posted June 13, 2006 Yeah any help from the rollaclub community on heads that bolt onto a 3K would be appreciated. Quote Link to comment Share on other sites More sharing options...
ke30king Posted June 13, 2006 Report Share Posted June 13, 2006 2k head will give you good compression on a 3k Quote Link to comment Share on other sites More sharing options...
Dan Posted June 13, 2006 Report Share Posted June 13, 2006 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. Quote Link to comment Share on other sites More sharing options...
