If he did want to go 4 port,n/a FI.. I dont think theres any OEM FI uim/lim that will mount and work,that would mean going to RB intake/carb..

Heres an example.
There was a so called "racing team" who used to post on TR,that claimed porting sucked etc etc..
Well they had a FC with a "bridge port" 6 port engine/carb set up.. and my friend beat him with a stock FC-SE only mod he had was a cone filter.
