hi
are the rx3 carbs the same as the ones on the rx7
a guy on ebay had one , he said that it came off his 13b
until he swithced carb's
just wondering what you guys would have to say about it.
thanks

 

if it was from the factory on a 13b it is a hatachi, the 12a carbs are nikkis, if you need a extra or better carb go to the junkyard and get a nikki, then rebuild, or send it to Paul Yaw and for $300 he'll make it THE best carb for a street rotary,(witch, by the way, is less than Rx7.com charges for a rebuild and r&r).

 

Hmmm...I have a spare working Nikki (for sale?) and about $300, does that Yaw carb run good for a stock port? You said "street rotary", did you mean SP, or just a street application?

A street application, or a race application that requires you to use the nikki.

thanks for the response. how much do you want for the nikki? .....TJ

 

how much do you want for the old rx-3 carb. i like them better than the nikki's.

 

They are Nikkis. The 13B goth Hitachis.

 

Not to scare anyone off a Yaw carb, but $300 will not cover it. Plan on around $500.
You need to replace the fuel pump, add a regulator, and buy a pressure gauge. Along with the carb pricing, which is slightly more than an even $300, and you are going to beat the hell out of a $500 bill.
It's worth it, but just be aware of all of the costs.
just my opinion,

What about the RX-2 carb off of the twin dizzy 12a? Is it the same as what is on our 1st gen 7's?

 

It is an early version of that carb. But the 7 Nikki is more refined.

 

I wouldn't say that is part of the price of the carb. After all even a STOCK engine/carburetor kinda needs the new fuel pump and accomanying regulator and gauge. Put a header on the car and you definitely need it.
