You're comparing apples to oranges. Boosted non-vtec 1.8 vs. a boosted 1.6L vtec motor. You can't safely say how much a car will put down without knowing what all you're doing. I mean are you boosting a stock motor? How much boost? What are you supporting mods? Are you getting it tuned?

There are plenty of guys that can give you a roundabout number, but you need to let them know more details.
