anyone have any pic of what the difference is? Or can u explain to me the difference? Can i convert my 6port to a 4 port? etc?

 

2nd gen turbos are four port, na's are 6 port. all the six ports are are extra ports that open past like 3800 rpms, letting more air/fuel in. i guess the thinkin with a turbo is that the turbo forces more air in so no need. yeah you can convert to a four port, block off the 5th and 6th ports, don't know why you want to do that though

gsl-se 13bs are four port too, but im not sure of any advantage of it in an n/a application, ive heard of some just opening them all the time, don't know how that does...


anyways visual differences on the block are:

4 port only has one intake hole on each housing, 6 port has two intake holes on the side housings... ill post pics in a bit if nobody else does
