WTB L16 intake for SU carbs

Post by obrut » 07 Nov 2018 06:06

I have a complete head, intake and exhaust from a 240Z and it came with round top SU carbs. I was thinking about rebuilding and using these on a L20B that I have. Does anyone have a L16 intake, I think its either a 220 or K14 intake for the SU carbs they want to sell?

510 SU's and intake are 38mm and 2 bolt for each carb. The z SU's are 42mm? And 4 bolt.

I think they are 46mm? and the research I did showed that they will bolt to the two bolt flange. I just put this out there to see if I can find the manifold for the right price since I have the carbs. Maybe I should just sell the carbs and go with the webers i originally wanted to run.

I wasn't sure or the size, 46 mm sounds right. I've also heard you can 2 bolt them. I run the z carbs on a custom intake on my lz2.3. I like them. Once setup they are usually trouble free. Full sets of 38's show up a few times a year on Facebook. I keep an eye on Datsun parts and needs, or dpan. A Webber 32/36 is also a great choice.
Good luck.

Yes 2 bolt vs 4 bolt but will still bolt up & work. Yes, the Z Hitachi SU's are bigger throat bore than the JDM 510 610 carbs, so you really need to fab up a spacer to go from the big bore carb down to the small bore intake manifold. I don't think there is enough "meat" on the intake manifold to taper port match, so you need to do it within a spacer. The OEM spacers are "Bakelite" to hinder heat transfer. You can make a taper bore spacer out of aluminum, but that will NOT help with heat transfer, will make worse.
