I am just plain sick and tired of some people here saying... 4G93 timing belt, I think it is Toyota Supra 1JZ or 2JZ or something like that. Others say it is from other makes or even continental but can't give you the exact OE or Engine it is from. Well if you are too selfish to disclose this information then don't post in the forum, if you don't know what timing belt you are using just say you don't know. No point leading people on or worst point them the wrong way. So here it is guys... 4G93MIVEC timing belt as per what I am using in my car.

Teeth = 159
Width = 1" or 25.4mm(it would be nice if you can find 29mm)
Car/Engine = Toyota Supra/7MGE or 7MGTE

I don't know if there are similar makes from MADZA or a CONTINENTAL CAR. If you have/using one please share and post it here.

For those of you embarking on the 4G93MIVEC route be prepared for these common problems after conversions(things that people don't tell you here) :-

1.) mess up the compression ratio(using 4G92MIVEC pistons which are too high) and get lots of pinging and knock, and at the end of the day a dead engine

2.) mess up the fueling(stock 4G92 ECU gives too little fuel) if you need more info contact me

3.) Kill your air cond compresser much faster (I have already changed 2 units up until now)

4.) Kill your power steering pump much faster (serviced once until now)

5.) You can never ever go back to stock base ignition timing of 5 - 8 degrees. You would be lucky if you could hit 2 degrees without knocking. Don't listen to people telling you 8 degrees is O.K because these people have no idea what knock is.

Good luck

Rabbit,

Sorry we don't have 4G94s here in Malaysia, I have heard about it but could not confirm it. But the teething and widths are good, so it will work.

Zoey,

7MGTE only have 1 inch width timing belts... I have not seen 29mm belts from Toyota. Where are u getting this info from? I have a OE timing belt chart in PDF with me here and it tells me different.

Zoey,

Try finding the timing belt from the local Mitsubishi spares dealer for it...:) and see what they tell you. And tell me how many of these do we have in Malaysia... last I remembered these are recond cars right?

Zoey,

Lets head back to the belts... again we have a problem here. You say one thing I say another. This is final :-

Toyota Supra 1JZ-GTE/GE belt is - 137 teeth 25mm wide 2.5L
Toyota Supra 2JZ-GTE/GE belt is - 143 teeth 25mm wide 3.0L

So NONE of these will work with the MIVEC conversion period.

the 7m-gte infos i got from were from a friend. i believe they were using this setup with a smaller tensioner bearing.

im using the 1JZ at the moment.
