umm fixstop is well know shop for honda upgrades. they do engine swaps, upgrade and the basic repair. sa HCP, they are well recommended and ive seen their work.
since d15b ang platform, they can also do wonders on your engine. from programmable ECU, engine, and suspension... they are well experienced. try visitng them along mindanao ave. and see what they can offer.
simple upgrades like Intake, Headers, Exhaust is a piece of cake with them.
EDIT: i think youll find that they (fixstop) are "budget friendly"
