datfreak Posted September 18, 2004 Share Posted September 18, 2004 just curious on jet sizes(air and main), choke sizes etc on 6 cyl datsuns???? would be good info for us motor "fiddlers" Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 18, 2004 Share Posted September 18, 2004 Proper jetting is going to be hugely different based on what size engine, cam, exhaust, intake manifold, 40, 44, or 50 carbs, etc. etc. Best thing to do is find a Mikuni manual. They are not terribly detailed but they will give you an idea of what each circuit does. Also the How to Modify your Nissan/Datsun L series has a pretty good section that has most of the info that the Mikuni manual has, and a little more in some instances. The best thing I did was to install a narrow band O2 sensor. I tried for a while to use plug color etc, and I made as much progress in 2 weeks of having the O2 as I did in 2 months of screwing with it with no sensor. People will tell you that you need a wideband, but I now know of 3 other people using narrowband with good success, and 2 of them have verified the accuracy of their narrowband against a wideband on a dyno. Oh, and be prepared to shell out some cash for jets. Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted September 22, 2004 Share Posted September 22, 2004 I'm running Triple Solex 40mm DCOE's and are having trouble with them. I'm using the Mikuni Short Runner Manifold, and an electrical fuel pump (Holley Blue regulated down to three PSI) I bought them from the "Italian Carb Guy" and rebuilt them. Where can I get jets, floats, and needles for these guys? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 22, 2004 Share Posted September 22, 2004 http://www.rebelloracing.com/ Make sure you verify all parts to be ordered. I've ordered from them a couple times, and gotten the wrong stuff a couple times. On the plus side the guys at Rebello are super helpful over the phone. Tell them what engine, cam, chokes, carbs, etc you have and they can get you at least roughly in the ballpark. Nissan Comp has very little left, and I guess the Malvern guy died...

preith Posted September 23, 2004 Share Posted September 23, 2004 I've had good luck with Overseas Distributing, I think they're in British Columbia. Their prices seem to be a little better than Robello's. They run lots of adds in Grassroots Motorsports mainly for Weber parts, but do carry Mikuni stuff too.

Drax240z Posted September 23, 2004 Share Posted September 23, 2004 We use overseas distributing as well and they are really good in my experience. Quote Link to comment Share on other sites More sharing options...

JMortensen Posted September 23, 2004 Share Posted September 23, 2004 WHAT!?!?!?!?!?! This sucks! Yeah, I went looking for their website to call them again about 6 months ago. The site is gone. I think I posted here asking for the number and was told that he died. Sucks, they were THE BEST people to call for Mikuni stuff IMO.
