He makes/sells parts for all motors these days, vtec and non vtec versions. While he makes nice parts, I think most of his products are a little pricey. The mans track record speaks for its self though. I read an article in Honda Tuning I believe, he has a genius iq level and uses scientific equipment at the race track, so he can run better times lol.
