    i think thats quite normal for F5M312, bcoz of the shorter gear ratio

    depending on ur objective
    if u r looking to be horsepower house, a drag or track machine, then go for standalone
    if its gonna be a daily ride with good amount of power, i think piggyback is enough

    a few friends of mine with 300whp uses piggback only
    piggybakc easy install and easy to manage coz u r still using the standard wiring and ECU
    only using the piggyback to 'cheat' the ECU a little

    so it goes back to ur objective..

    Alright thanks guys. Short ratio it is. Thinking of what else I can do. Haha. Gonna make a custom gear boot to fit first thats the first objective. Maybe make a matching handbrake boot with it together.

    If your oil change interval on time you actually don't need to flush. Beside chemical flush you can use cheap lighter viscosity oil to flush also.

    basically, I agreed with VR2, I don't do flush..

    just make sure the engine oil are changed at every 10k or on time.
    personally, I feel the flush will do harm than good..
    damaging the seals etc..

    For turbo engine, I actually recommend earlier OCI. My VR engine never pass 10k km those days but still looks dark inside. I think change at 5 to 7k km better. NA can go 10k km, engine not as hot....:driver:

    after overhaul, very good to drive.. very efficient..

    last time, 1 day I can use up half tank or a quarter in city drive.
    now not even close.. :biggrin:

    although engine oil are cheaper in sg, but cannot be so wasteful bro..

    once a year, I will still send for check up, change of E O
    fully synthetic only.

    Is standard schedule, even car manufacturer set 10k km or 6 months. This is due to contamination of the oil. The less you use the car, the more likely water vapor is formed. Of course it is up to you whether you want to change in 6 months or 1 year....:driver:

    Helix Ultra during Tesco sales time around RM149, sometimes even cheaper.....:biggrin:

    say 30-40k kms should be fine, but ensure to use those branded engine flush
