kj280z Posted March 20, 2004 Share Posted March 20, 2004 Anyone have any experience with Mikuni 44mm (N44phh) jetting for a 3.1? I have an extra motor laying around that I was going to put in my 240Z... It's 10.5:1CR 3.1liter with a .540 270/280 cam (P90 head shaved and shimmed) I have an opportunity to get my hands on the carbs so I figured it might be worth putting it all together. Probably would be used for autoX and occasional road coarse days... doesn't have to be the fastest car out there, but "kinda" drivable on the street (as drivable as possible)... Anyone have any experience with a "similar" combination? Quote Link to comment Share on other sites More sharing options...
Dan Baldwin Posted March 24, 2004 Share Posted March 24, 2004 I've got 165 mains and 190 air jets. Still have a big rich spot in the midrange, very localized around 4500rpm, I suspect reversion. Up top it's a little lean. Anyway, should be a good starting point. Quote Link to comment Share on other sites More sharing options...
