So i finally decided what motor am gonna build to put in my RX2. Am gonna build a Semi-Peripheral port 12A. But my question is do i need a custom intake manifold or can I use the stock manifold and custom build that one.

 

Check with Pro-Jay. They used to make one for the 12A, but I dont see them on their website...

Stock carb wont be enough for a gas thirsty semi-PP motor. his link above is for a holley type of set-up. I'm sure Rene (RX3mist) can do it as he has done for us in the past using weber downdraft with TWM

 

I check pro-jay but only saw intake for 13B's. I've got a weber carb that i plan on running.

 

sidedraft or downdraft

 

I've got a down draft weber
