I have just imported a stock CRX SiR (DOHC B16A V-TEC) and I am very surprised by it's standard performance. However I have owned some pretty quick cars so I am in need of a bit more power. I have emailed Toda Racing about some of their products but they have not replied yet. Could anyone suggest what I can do for a bit more power without going to crazy (stroker kit out of the question). I was thinking some cams, cam gears, valve springs, timing belt, exhaust, vtec controller and air filter upgrade. What do you guys think about what I have listed? Any other suggestions would be great.

Cheers
