Naa koy bag-ong gikalingawan ron, currently bought a Honda City with a D13B-4/PH13Z engine PGM FI Manual Transmission, naghinay2x na ko ug pang modify sa makina from Throttle Body coolant block bypass, Intake air sensor modification for a leaner gas squirts thus improving gas mileage, radiator mod for best heat dissipation, Radiator Temperature Sensor Mod, Plugged the top cover breather and installed a filter, plugged the Oil Chamber Breather and also installed a filter, All my mods so far gabase ra sad ko sa JDM D13B-4 Service Manual, unsa pa kahay laing mabuhat nga mods ani mga bossing?
Im also planning to modify the engine HV distributor design, from a conventional 4 point HV selector via cam, gusto nako himuon ug pulse sensed iyang switching para wa nay mahilis nga contacts pero kinahanglan ug 4 kabu-ok nga ignition coil, pina ford ignition system ba hehe, karon unsa kahay angay nako gamiton nga ignition coil mga bossing kanang compact na nga 4 piece ignition coil with a 36KV rating on the output? I was thinking of getting a Namban ignition coil for MC kay sure ko 36KV to pero low resistance ang HT wire which is not good for a bit vibration kay by and by maputol pud so unsa kahay nindut gamiton nuh?
Im also planning of installing a clutch switch, in this way di mustart ang makina kung wa ko gatunob sa clutch since manual man ni (U.S. Version Hondas have this) in this way mas safer siya compared sa current set-up being sold here in the philippines.
Also planning to install a custom ignition kill Switch, in this way maabtan gyud ug buntag ang mu attempt ug carjack hehehe kay ako may magbu-ot asa nako putlon or asa nako itago ang magnetic reed switch, the switch im going to use is a magnet activated switch
Also planning to use a smaller injectors to improve fuel mileage...
Also Planning to remove the Fuel Tank EVAP System...
Im currently analyzing on how to fix the idle @ 750 RPM even if it`s still cold or first start, Im still studying the principles and mechanics of the MAP sensor (Manifold Absolute Pressure) kung unsa-on nako ug ilad2x ang sensor para ma-ilad sad ang ECU because I want the PGM EFI System to behave like a Carburetor Type siya, wa nako hilabti ang IACV kay perfect pa iyang operation...
Note: ang gusto nako nga mods mahitabo kanang maka improve ug gas mileage, dili pang racing2x,
I think the wildest mod ani kay resleeving the block and put a 60 mm. piston to make a 214 CC on each cylinder, a total of 856 CC instead of a 75 mm. piston (1343 CC) pero mangavass sa ko kung pilay pa resleeve hehehe
