hello everybody,
i hav a hyundai elantra, i hav just put a 4g67 dohc engine, the gearbox was for 1.6 and am using the same gearbox.
i want to know if the performance will change if i use a mitsubishi 1.8 gearbox?

Hi Yogesh,

Did you buy the full half cut of 4g67 and implant it all or only the engine?

The performance will definitely change and believe the mitsu 1.8 gearbox would be more suitable for your 4g67

Hi everyone,

Im using Proton Satria 1.3gli...i dont know what happen with my car now. Every morning it took me 10-15 minutes to start my engine and not powerful anymore. Some of my friend told me its because of the fuel that i change 3 months ago...97 change to 95. But recently i change back to 97,hoping it will change back...but it still have the same problem.But some says maybe its because of the sparkplug or the cable...can anyone help me on this matter or maybe you can share your experience with me. TQ!

Heya gianni76,

There's alot of things you need to clarify. Let me try and help you to determine if possible.

1. when you start your car, do you turn your key for a few seconds or do you start your car by turning the key until the engine starts? It's as though forcing your engine to start?

2. do you press the fuel pedal to start the car?

3. when's the last time you change the spark plugs of your car?

There is the possibility you'll need to change your spark plugs ... unless you just recently change them, then you need to have a mech check your starter.

Recently serviced your car? Try check your air filter too ...

Not all cars get better fuel efficiency from using RON97.

Older cars and some jeeps perhaps actually have a better fuel / money efficiency in using the ron95.

I've tested so far only newer cars (eg. Honda city 4th gen, vios both old and new, hyundai rx-s, persona, gen 2, neo) seem to have more value for money when using ron97 petrol.

Yet on Wira and Waja, the mileage has only a slight difference and depending the year of the car - sometimes no difference at all. End up spending more.

97 95 or 92 also nothing to do with your slow start....
you should try

1. give your car a quick service If you can, no more xW50, use a xW40 for starter

2. remember to change the plug too... and please, no cold plug cause your car is still in stock and maybe

3. slow start can be a trouble starter too... check that if after step 1 n 2 not work for you

one more little thing... is your car heavily equipped with other stuff ? like a change pulley? racing belt? or did you use some kind of engine oil additive for long time?
