i will be getting a weber 48 and rotary engineering intake manifold off of a 12a and i want to install it on my 4 port 13b. i be willing to trade for a 4 port down draft intake but no one seems to be interested. should i get the adapter or just go ahead and get the new intake? thanks.

 

I have a 12A lower intake to a 13B 4port motor adapter but the last I heard the company where mine came from no longer makes them...? I could be wrong, but anyway... It works flawlessly.

 

if you can get the adaptor then just rock out that route. save some $$$ and hassle.

 

theres is a company i came accross a while back that made pretty much every intake adapter and they made dual belt alt pulleys. i cant remember the name of the compnay though.
