[fatz]

due to a previouse person( who f**kup tapping a hole) i cant use the top tentioner location so i have to go the lower tentioner location

i got the belt that the guide says to use however the teath on it have a curved edges

instead of the standard trapazoidal shap(triangle with top cut off)

so the belt floats on the cam gears and lower sprocket..( eg not right)

does anyone have the correct part number??

Im pretty sure its HTD profile you want.

I messed around with some ca20 twin cams a while ago and got my belts from econobelt

http://www.econobelt.com/Q460/RFQ/default....ge=tbelt/12.htm

they do a standard 20/30/50mm width for $23 usd, or they do custom width for a little more, i think i paid around $30 each. you need 25mm for RB

Im sure Gates australia could help you tho, try giving them a ring

that's the same belt i have..

it fits, majorly tight to put on but it fits

i noticed the same thing with the teeth but so far the car has seen consistant revs to about 5500rpm while getting a running tune and it hasn't moved.

to get it on we needed 1 person holding the tensioner and belt and pushing in, the other person has a ratchet ready to screw it in

good luck

Glad to hear you got it sorted out.

I just thought I should mention to be very careful when trying to choose an equivalent timing belt of a different length for your car. I only say that as there are about 10+ different styles of curved tooth profiles for automotive timing belts out there. Unless it actually says HTD on the back of your belt it will not be easy (near impossible) to identify exactly which one you need. So as mentioned above if you're unsure then contact Gates or someone similar to find out what the standard belt tooth profile is.

If you did have a HTD belt don't just go to an industrial belt supplier and find an equivalent one either. The automotive belts are typically designed to cope with much higher temps.

What even better is that it's up and running and if fatz can NOT be drunk for 1 night he might actually come up to shit'sville(newcastle) and drive the thing home next weekend.

WOOHOO

and take all the associated junk with him. hehe
