When I purchased a GSR motor for my EG civic hatch it came with a Edlebrock Victor X IM. Other then a mildly ported head the rest is stock. From what I understand the Victor X is for boosted applications and may hurt performance on a stock NA motor. What kinda of power gains might I be looking at if I change the IM for a Skunk2?

 

Don't know if this is what you were looking for.

Thanks, that definately helped. From what I read the Victor X is for much high HP goals then what I have. Although most people recommended the Performer X, I can get a sweet deal on a almost new OG S2 IM.
