Notwithstanding, on a factory NA engine that isn't built with lower CR, an EWG is probably total overkill. On my old STi I ran between 28-30 PSI on a GT30R and an IWG absolutely wouldn't cut it.

With the right preload and a good boost controller you can get some real good results out of the IWG. No dough EWG are better as the HP goals and boost demand increases. Here is a dyno graph of a car we just finished, it has our VQ37VHR stage one long block, Stage 2 turbo kit with internal waist gates running 16 psi, as you can see it does very well .
