what webber should i use?
what type of fuel pump?
what porting does actualy?
what is the best to do?

 

Hello, and welcome to the forum. The majority of your questions can be answered by visiting the FAQ section, or you can run a search and read week's worth of debates and information. Also, I didn't know that 12a motors came in a six port version (thought just 13b did, but maybe I'm wrong). Good luck on your quest for information, you came to the right place..

 

awesome, you have a rare 12a. altho, i think the 6port 12a's aren't any more powerful than the 4 ports. eitherway.. you are probably going to have an issue getting an intake manifold for your webber and you won't be able to port as much inside. i'd get a nice ported as **** 12a 4 port.

 

pluging in the webber, does it bring any problem!
help me out to get the right the instrument
actualy it consume a large amount of fuel, i mean the 6 port (am i righ?)
that is what i've read so far........
only that i does not bring any sence of speed or power..
that is i've plan to plug in a webber......
palnning to get a 51mm..... so far
does it fit?

 

AFIAK, non-north american market 1st gen's had engine's like this:
s1: 12a carb
s2: 12a 6pi, 12at?
s3: 12a 6pi, 12at.

 

yup
and i need help

 

a webber actualy
need a webber....
what type and part number!

 

i wouldn't go with anything bigger than a 48. the carb isn't the problem, it's finding the correct intake manifold to go between the two. being a 6port 12a and how rare it is... i dunno who makes one that fits

 

Hi and welcome to the forum. You might get better help over in the other rotary section. Thats where 808, cosmo, Rx2-3-4-repu guys hang out. I dont think you can get a manifold for a 6 port 12A for any carb sorry. You have a Nikki on it now? Or is it EFI? I forget what those old skool 6pt 12a's had. If it has a Nikki we could build you a modded replacement. And it would be a bolt on deal for you.

 

nice man
thanks alot
so not bigger than 48
i've decided to plug in a 51
i'll try
which forum
