yeah cheers I've read that one during my search, it mentions both 510sss and sp311 roadsters. Just wanting to know if one is better than the other. Gaskets are the same but needles different (never had anything to do with hitachi's as you may guess from my newbie questions!!)

bump

anybody know whether 1600sss/180bsss or SP311 1500/1600 twincarb rebuild kits are better suited for a12t hitachi carbs??? from pictures i've seen the needles are different lengths??? thanks

After the above manifold with standard size a15 ports for twin hitachi/su type/gx carbs. Can also swap for a a12t twin hitachi manifold with larger ports. From New Zealand but happy to ship from anywhere. Thanks.

thanks guys, this was what i was hoping, hopefully with a bit of porting it will at least be close (ish).

just wondering whether the oval port a12t (looks like a flat top gx hitachi carb) will fit on a a15?? i've just managed to find one and am deciding whether to start building an a12, but would prefer an a15 if they'd fit. Thanks

i'll take the oval port one, i'll send you a pm

i could always sell you my starsharks with staggered fitment and better offset as a 3rd option to make your decision harder!!

i got mine from nissan

i brought one new for $113 from repco if that helps
