Where can I have 12a housings peripheral ported? I would rather not buy new ones already done. Anyone know the correct diameter hole to use? How about a carb setup to accomodate? Fuel pump? All info is appreciated!

the carb/efi is easy you need a 48ida weber, or they have 48ida efi throttle bodies. the factory pp race cars have 3 fuel pumps with a surge tank (they had the 79 insa gtu car at sevenstock).

on a 13b you can buy racing beat housings cheaper than you can have one made, but on a 12a the factory ones are the only ones you can get. the problem with a diy is the port timing, theres no published specs for the pp housings so nobody knows where to put the hole

go to rotary reliability, talk to nick he has the best p-port housings!

we used his housings on our all motor rx7 and we went 11:40's with a weber!

tell him robert sent you! 714-839-8018

So the Weber would be the carb of choice? I can't find a used 48ida on Ebay. Are there any other carbs that would work and are reasonably priced?

you can buy em new again, right robert? the 48ida is about the only carb that works
