There's ways of extracting power out of any engine if you do enough researching. For instance, a version of my engine (KF 2.0L V6)was what Ford used in the BTCC series races and it put out 311 fhp and was tuned by Cosworth. Later, they did the KL (2.5L) and it put down 389 fhp and there's been members that have gotten within 50whp of the lowest mentioned number. The point is, instead of looking for a tuner that makes 3G eclipses faster with simple bolt ons, look at mods done to other engine designs similar to yours and find a way to make it faster by using the best of both worlds. Your engine is an SOHC design, but that don't mean that the power ends there. SOHC engines can also make decent numbers as well. VW's flat 4's and 2.0L is a prime example. Others would be the Honda D series and Ford 2.3L. Look around at those engines and see how some of those guys got 100 hp per litre.
