So what parts do you buy first? Well here's how i would do it....
1. Intake - good gains for little money. Go for sealed/heatshielded airbox.
2. Longtube Manifold & decat - gives excellent gains with the intake
3. Cams - TODA spec a/b/c; CAT Spot 902; Honda DC5R cams
4. ECU retune - Needed to make the most of the above mods.
You should be running at 240-250 bhp already, not bad at all!!
To get max power on the existing cylinder head (about 10-15 bhp extra max) will take a lot more work.
5. Throttle body & intake manifold, cat-back exhaust - frees up the breathing even more for more top-end power. Notice that the std exhaust is actually pretty good. A cat-back will only produce a nicer and little bhp gain.
6. Peripheral stuff - Prevent power loss from heat-soak. Wrap all the intake tracts with heat-insulator, insulate the intake manifold with a hondata gasket, ceramic coat the intake. Watch for heat soak from the radiator to the intake manifold. Use low temp thermos and switches. Wrap your aftermarket manifold. Heat soak cost between 10-15bhp!
7. Ground wires, new sparks etc - minimal gains from these, use if you run out of options!
So by stage 7 you have roughly 255-265 bhp from this engine if you are lucky, and its a cold day. what now?
8. Gas flowed & ported head - increases flow to allow better breathing for high bhp at high rpm. You may lose torque, but will be able to break the 265bhp ceiling.
9. Thinner head gasket - be careful here, high lift cams may cause piston-valve contact.
10. custom high comp pistons forged, with con-rods etc - now we are getting serious.
11. Custom billet cams, Accord block (2.4l), custom forged crank - we are talking silly money here but if you want 300bhp and 200 lb/ft this is the way to go. Most aftermarket cams will give 260bhp max as they are limited by the engines compression ratio and the cylinder head.
12 you want to stop properly now- call AP/brembo for some new discs and calipers.
13. You need better suspension now - JIC FLTA2/TOda fightex/Tein are all good
14. chassis bracing - gotta kee p the engine attached to the chassis.
At the end fof all this you'll have a superfast hatch, and be £30,000 poorer (not including car).
Of course , you could go turbo or nos. In that case, save 30,000 for maintainance.... you'll need it.
Just out of interest, would anybody out there want to buy a turbocharged honda from a boy-racer? Keep it Normally aspirated, and its easier to conceal...
