    Default Why D15B 3stage Vtec is more fast and powerful then D16W9 3stage Vtec?

    assalam o alaikum n here r the stats for both of these engines ..

    D15B 3-Stage VTEC

    Bore and Stroke :75,0?84,5 mm
    Displacement : 1,493 cc (91.1 cu in)
    Rod Length : 137 mm
    Rod/Stroke : 1.62
    Compression : 9.3:1
    Power : 130 PS (96 kW; 128 hp) at 7,000 rpm[6]
    Torque: 139 Nm at 5,300 rpm
    VTEC 12-valve to 16-valve switch over : 3,000 rpm (below such engine speed, the engine is operating in 12-valve mode)[7]
    VTEC high cam switch over : 6,000 rpm
    Redline : 7,200 rpm
    Valvetrain : SOHC, four valves per cylinder
    Connecting rod length : 137 mm
    Connecting rod big end diameter : 48 mm
    Fuel Control : OBD2a
    Head Code : P2J-07
    ECU Code: P2J (small case ECU)***


    D16W9 3-Stage VTEC

    Bore and Stroke: see D16 Series Engines
    Displacement: see D16 Series Engines
    Power: 130 hp (96.2 kW, 131 ps) at 6,600 rpm
    Redline: 7,200 rpm
    Valvetrain: SOHC VTEC3 (4 valves per cylinder)
    1st VTEC Switchover: 2,500 rpm
    2nd VTEC Switchover: 5,500 rpm
    Fuel Control: OBD2

    As the stats aboe show D16W9 should be almost equal in fuel efficiency to D15B but it should be more powerful then it due to being 1600cc and having 130HP where D15B is 1500cc and has 128HP

    I need some experts to clarify it that why does it happen? and I have seen many D15B civics smoking 7th Generation PKDM VTI civics quite easily .. while both on stock

    Brother Altis 1.8 1ZZ-FE is 140HP 1800cc VVTI whereas Civic Vti D16W9 is 130HP 1600CC. Low end torque is not good of altis but after 4k rpm it roars. But if 1ZZ-FE is raced against R-18 Civic then probably civic would win.

    Well i've blown xli and se saloon many times on motorway. Except 1ZZ-FE no other corolla can catch Oriel. When 1zz-fe is raced against Reborn civic which has R18 engine then it is fair comparison. 1ZZ-FE can be bit harsh till 4th gear after that R18 will out run it. Xli has no caliber to run with civic. After 150km/h xli is highly unstable and has bad brakes.

    Guys I think you need to slow down a bit as these are not sports/racing cars. It can go well for 10, 15, 20 years, but it takes just a moment to become fun to disaster. Value your and other's lives on and off the road.
    Almost everyone in Pakistan is doing corruption to the extent they can. Our leaders are doing at the level they can do. So why should we complain?
