    If the car is on petrol, n after such mods, if it wont go above then check, acceleration cable replace it with new one, proper tune it or its time to replace its clutch plates n pressure plate.

    @Shazo,
    Which Clutch should i go for replacing??Tell me which brand runs long??How many punks 6 / 8??i need my d15b3 carby to beat or at least give a tough competition to any vtec engine with d series, one of my mechanic friend suggest that It can be a Fuel pump problem??Maybe my current fuel pump is not supply fuel to carby on high speed/car momentum, if that so, what should i do? Replace the fuel pump? Which one i should putt on??That may give my car enough fuel to reach carburetor to go above 140km/h or more...please advice the brand name??

    If ur car wobbles a lot on releasing the clutch then clutch gone else its ok...coz as u stated it goes fine till 100 km/h doesn't seems clutch problem....Yes fuel pump can b a problem because if its weak it will not be able to supply enough petrol on high revs. Check the fuel pump pressure and get a good tune.

    @immad100 / wonder_guy
    Wats pmp stands for??isnt it on vtec engine? As I already mentioned that i have d15b3 carby engine, non vtec,I’m getting 0-100, on all gear on half clutch, clutch is not even loose or too tight,it fully presses down & comes up perfectly, i don’t think its clutch problem have checked with mechanic already, as for Fuel Pump,my question still didnt answer yet
    “what should i do? Replace the fuel pump? Which one i should putt on??That may give my car enough fuel to reach carburetor to go above 140km/h or more...please advice the brand name??”

    As your engine is carby so it wont have a separate fuel pump, your fuel line is connected with carby fuel pump, as Wonderguy said, go to a good tuner and tell him your problem, he will check the fuel line and rest too.

    @ poster
    Check exhaust of ur car as car doesnot accelerate if its exhaust is choked.
    as per my experience of civic 95 if engine is getting less fuel then it will not respond on 1st and 2nd gear also.
