na 4 port? and vdi?
my friend did this with his 86. and he got a significant increase in power. he also streetported his irons. his powerband started about 3800 rpm. using the lim off a tII and the rest of a na.
i have a s5 n/a and wondering about going this route with mines. i was going to use stock ports minus the diffusers so i can keep that low end torque. im thinking about going this route so i dont have all that vacum lines. its confusing the **** out of me. is this a good route to go? any suggestions?
another ? is what exactly does the vdi do? and can i still use it without all those vacume lines and solenoids? dont know too much about the vdi system

they never put a 4 port n/a in any rx7's other than the first gen. And that was a 12a. the upper intake manifold off a n/a will not fit on a T2 lower. . The VDI valve is opened with pressure
