JDM cars brought into Malaysia need RON100.

I also forgot to add, in addition to JDM cars, all those who has done conversions (GSR, EVO, B16A/B/C, B18C, etc etc) will also need RON100. They are afterall driving JDM engines. So there's actually a rather large crowd with every converted car needing or rahter, been thirsty for it for a long time.

Did you modify the internal parts of your engine? Like increasing the compression or heavily advancing your ignition timing? If not, then you don't need RON100.

RON100 does not improve performance and only required if your engine needs it. An engine that requires RON100 and runs on our standard RON97 fuel, then it's performance would be degraded. Putting in RON100 back into the engine would restore it's power.

It only benefits those that require it otherwise it would be no use in normal engines.

Which V-power are you talking about? V-Power Blue or V-Power Racing Red?

Well, all we need is just get the JDM boys to try it. If they get more power, then we know it's the 100 octane that their engines are craving for. If it does not feel like anything, then it's the same old formula with a different colour.

All their fuel is red... or pink.. or merah jambu.. whatever you want to call it (except for V-Power). What he was talking about is that we can't tell the diff if some petrol kiosk 'campur' the new V-Power Racing with some RON92 fuel and we can't tell the diff.

Oh well.. too bad for the JDM boys.. their precious engines will have to continue to run without the precious RON100 petrol.

Don't need it. Mine's a WRX Type UK. Don't need RON100 like the JDM boys. RON95 and above will do.

You can get octane boosters in any accessory shops or even make them yourself. Plenty of recipes online. However it's just too troublesome to use it everytime you pump a full tank and most just don't bother.

If you have read the last few replies you would have gotten your answer. It does not benefit the car unless it requires it.

There's no effect in your car because your engine is tune to run with RON95. Since Malaysian fuel is already RON 97, there will be no effect on your engine.

A proper octane booster will usually include a rough guide to how much octane it will boost. Usually not much, around 1-2 octane. Outlaw looks the best because it has the 4 metal canisters.

Again, octane boosters are a waste of time as it does not increase power. The higher octane allows you to run a more highly tuned settings without damaging your engine, like higher compression or more advanced ignition timing.

My previous Satria GSR and my friends EVO's all runs better with higher octane because the engine and ecu was tuned for Japanese RON 100. However, it's too much of a hassle to keep adding it to the petrol tank.

Actually diesel engines squeeze more, up to 5 times more than petrol engines. Diesel engine compression ratios goes up to almost 50:1, compared to an average 10:1 in a petrol engine.

Turbo will not lose. GDI does not produce that much more power. The Lancer 1.8 GDi produces about 7HP more than the standard 1.8 4G93 at 147hp, while torque figures are higher at about 180nm. That is still very far from 1.8 4G93 turbo that produces 205HP and 249nm of torque. The GDi would have better fuel consumption than a standard 1.8. Of course the best would be to use the popular 1.8 GDi Turbo that Mitsu has in some of their Lancer models.

Not because we remember all of them but because some of us have or had those cars, so we are very familiar with the specs of those cars.
