have a rb30det

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)

have i got the wrong belt?

does anyone have the correct part number??

the belt i have is 1200mm long 150 teeth 8mm pitch

help please???

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

      My theory would revolve around the ~4000rpm point being peak torque territory on an RB, where you're supposed to be looking at max efficiency of the head, etc, and....just not having it because the skinny ports are doing something to f**k it up. I'll admit, it's a loose theory.

      It could be in the tune but in both cases it couldn't be completely solved or eliminated by some of the best tuners in victoria so I'm DOUBTFUL that it's in the tune or ECU but stranger things have happened of course. I've pondered that theory too but is there any theories that thinner and smaller ports overall would cause a turbo to spike? I would've thought it would just restrict it in general if it was small enough to make a difference. I wouldn't expect it to make a different at what is essentially sub 300kw at 4000rpm anyway. I think the next step is going to have to be the 6psi spring to rule out the idea that the gate is cracking open far too wide initially. At least that is the cheapest (free) thing to check initially.

      I'm thinking it is skinny NA Neo port sizing and cams. Somehow.

      -5’s did it. 8474 did it. Not hot side related. ECU related? 🤨🤪

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Above you mentioned you only need to sand primer if there's an issue with it but with fillers it says the surface needs to be sanded to X grit beforehand. Does that sorta contradict that point as the primer hasn't been sanded yet? At the same time if I sand the primer, there's a good chance I'll expose the bare metal and I'm just chasing my tail at that point. Or I'll just use a sand sponge instead of sandpaper, it seems to be far finer in terms of abrasiveness as opposed to sandpaper. From what I understand, filler is like primer and needs scratches from the sandpaper to help it adhere to the panel. I realised the way I'm doing things is actually a bit counter productive as there's a chance after I put filler I will need to put epoxy primer again as opposed to putting the filler first and potentially no primer if I don't go to bare metal. Will keep this in my mind for the rest of my repairs.
