Which engine? Probably about 130bhp now... the spark plugs will add barely anything, just make the car start better and be more efficient. The induction kit needs a proper place to draw still, cool air from to be effective. And the ECU- is it tuned for your car? Or someone else's?

it's a D15Y7 Vtec single-cam...the ECU was tuned at a nearby Honda garage... probably need to adjust gear timings as well...

Good engine. A closer-ratio gearbox will work wonders on it. Try the gearbox from a D14-engined car.

yeah a good choice indeed...i did add a 4-speed close ratio gearbox and twin-plate idle for smoother revs...
