    Lightbulb Issue with 5afe acceleration. any expert to comment ?

    AOA.
    I recently bought AE100 Corolla 1994 model. it has 5A engine with Auto-transmission. As i am not found of picking up races in city , i mostly drive on motorway on daily basis, so sometimes i do acceleration. i was expecting the car with though at least 150 km/h on petrol, but it hardly touch 130-135km/h without A/c .
    the engine is in good condition, no heat-up , no smoke, no oil problem.
    Looking solution for the problem i changed the exhaust system to 4-2-1 header of GT style with 2 inch down pipe and original exhaust box at back.
    though it proved on the pick up , but still lacking behind on top speed.
    What can be the solution? it has an original Air cleaner, i changed spark plugs and installed NGK's spark plug.
    How much should i expect the top speed on long run. Is Auto-transmission need to be change with an other gear box or should be inter change with Manual gear box.
    or any other option.
    Expert opinion are invited. Thanks

    What is the condition of transmission fluid and what fluid is being used? Scan it to have any errors

    oh fuel filter. sorry for misunderstanding. @affan

    @ raja bro i have changed transmission fluid with Zic , it was very contaminated. secondly i feel like transmission is weak. the reason is that few days ago i was going some minor work in mechanic work shop and when i started the car and put it in " D " it wasnt moving even i pressed the acceleration, after few seconds like 5-6 seconds then it jumped. that made me realize its transmission is also weak not making quick pressure.
    So may be i changed it as well. Btw can performance wise A/T is better or M/T.

    Fidgeting with an original car to modify isn't a good option.
    Petrol filter change kai, things will surely improve, even the pick

    Each has its own pros and cons just scan out the codes and which Zic fluid did you pour?

    was the ATF filter/strainer opened ?
    ideally its supposed to be changed but cleaning it works too (only if a replacement is unavailable)

    Fahad bro, actually the crank case of transmission had leaks, the previous owner used silicon instead of original "Packen" . So i opened it , cleaned the filter as well and placed the original "Packen". but it seems the transmission has lost it punch. i hardly get any time to spare for mechanic shop thats why the results or filter change and code checking are still awaited.

    Besides i also want to lower my car, currently it has 14 size rim. i don't want to lose the whole shock performance but also want to get some look , how could both be possible ? Coil over are better or its own shocks with trimming the spring.
