Portworks Racing Dynamics releases their new fully ported 2006 si (RBC) intake manifolds for k-series engines.

similar to import builders, hookups, etc. these manifolds are genuine honda intake manifold cut open, fully ported, then welded back together

here are a few pics







we will be testing these manifolds on our SPFWD civic and few all motor k-series setups

for more info pm me

 

looks awesome

 

 

Wow. nice work. i wish i had a K series.

some serious parts coming out for them

platinum.

 

looks good but if i was opening it up and everything i would weld on velocity stacks

 

there wouldnt be any room when you put the manifold back together. you would have to make a custom sheet metal plenum. this is more of a factory bolt on replacement manifold.

 

take some 3/8th inch donuts of stainless steel and weld them to the bottom of the plenum at the runners lol

 

That's a lot of work, We've a few and people .

Looks very nice.

would be kinda hard to weld stainless steel to a cast aluminum intake manifold

 

lol oops, then use aluminum lol
