Can a Nikki bolt onto a 4port intake?
 
I need to know if a Nikki carb would bolt onto an early 4port 13B intake.

Thanks, Ed

depends on how early, i have a 74 13b intake with the hitachi carb and the nikki definitly wont bolt up.

i have an early 13b intake manifold and it has a spacer that is also an adapter for the holley thats on it. the spacer/adapter was CNC machined from a block of aluminum. i got this when i bought my car, if youre interested in it. id let it all go for cheap.

the nikki stuff is on the right.
the nikki intake is way smaller.

You have to tap/install new stud since the 12-A carb is smaller.

You're planning to go turbo with this carb yes?

I would think you'd want to run something bigger on a boosted 13B than a Nikki...modded or not. IMOP the cost issue wouldn't be worth having a strangely fitting (and probably flowing) carb/manifold setup.

Does rotaryshack recomend that carb for a boosted 13B?

yes you can retap it, but no it does not bolt right up.

^^ a weber would be a lot better for a boosted 13b for sure.

would that be the same as my 74 repu?

Guys, thanks for the replies! Yes this is for a boosted application. I already have a boost prepped weber 48 that I plan on using but was just playing around with the idea. Kind of expanding my options since I having a bitch of a time trying to find a 1piece wrap around intake for my 4port.


Thanks, Ed

just get a 2 piece style intake, that way if you ever go back to 12a or a 6 port all you will need is a new lower and some jets. :icon_tup:

Keep in mind that this carb has been sitting for many years. It was in my 13-B streetport which is no match to my IDA. This is a 76 intake manifold with reversed runners.

i have an rx7 nikki on a rx4 manifold, all you need to do is drill and tap new stud holes, took me about 20 minutes.
