Putting money into the valiant, suggestions?

What can I say, I've always been a V8 kind of guy. That being said I have owned two 6 cylinder cars. First was a 1987 Buick Grand National (Made lots of performance mods to that thing, great car, easy to jerk the frontend of the ground). Second was a 2002 Nissan Skyline GT-R V-Spec 2 Nur model (one of 750 made and it was all stock, down to the twin turbos.

Then, your post is like me passing out engine advice over on hotcivics.com... I've never owned or worked on a single Honda in my life, so I don't feel informed enough to offer suggestions to tuners. Nor would they have any interest in what I have to say.
