I've found it very interesting that J's Racing doesn't use velocity stacks on their f22c motors like Toda does for ASM or like J's does for its own Fit racer. I wonder what the J's motor at 13:0 compression would make with velocity stacks and no intake manifold. This is their most recent setup, though.

^ The velocity stacks are just housed inside the welded aluminum manifold.

also the Nissan Pulsar GTiR, a version of the SR20DET with itb's and probably the largest T28 built.

I may possible be going with ITBs(although I'm not sure what hat will do to me with points considering I want to get into Nasa TTC) once I can get everything I need for the conversion. Will do a full write up if this goes down.

Endyn claims their manifold is better than having ITBs. Nearly the same mid-range and more top-end.

+1

Even if hp/tq were the same, throttle response is still the big winner for ITB's.
