As much as i agree as this does sound a little dodgy. u need to have a think about the guys that go all out and spend 17+g on there engines alone. 250 is a small price to pay to save a big dollar engine not to mention that when they build these engines they get the best of the best parts, and i presume that thiss is the best belt. even if its just for peace of mind too.

A kevlar belt seems to be a good idea one you would have less wear reducing cam belt changes at the regular intervals.If you used a cheeper belt and it snapped how much would you be up for? Even the v8 super cars run a carbonfibre based tyre wall .the teeth on the kevlar would be stronger ,this would create less wear on cam gears giving it a better mesh .

Timing chains......you guys.......

EBAy gates belt

THis is what you are talking about. One of these would be the go. But I seriously doubt if an aftermarket timing belt is needed if you run stock cams. Considerign they are supposed to last 100Km.

two steel chains turning twin overhead cams is better

A steel chain turning a ohc is much better

A steel timing chain is better. Go the A series!

you can buy the gates racing belts for Just Jap, they are $105 their but i have seen them cheaper but i cant remeber where.

I think this is for his ca dattoman.

Belt ?

Doesn't this interfere with the correct pushrod operation ?
