Hi all.

I bought the 152 tooth timing belt that Spool imports supply for the rb25/30 conversion.. But its not long enough... !! My fault not Spools!

I used the rb30det.pdf thats around to setup my tensioner pulley. Were its written in a picture were to mount the tensioner.

i need a other belt that is 2 - 3 tooth longer.. 4 -5 tooth will prob be okay also. Were and what can i use? I have looked in Dayco wepshop, and can see the tooth proflile for the belt used in the .pdf file is: STP8M (Dayco number 94407).

Can I use other tooth profile? Or is my only option the 164 tooth long belt? If still need to be STP8M profile...? Do you think i can use the 164 tooth belt??

Really hope someone can help me out here.

CA series motors only run a 3/4 inch belt ~19mm wide, the rb belt is inch ~ 25mm wide. Are you sure your belt is not hanging over the side of the idler?? it will wreck the belt in minutes of running

i would say that you will wreck the belt like that.

Can you get another RB tensioner? they are the correct width and also seem to be cheaper than the RB idler pulleys. Plus like proengines said, you can adjust it to suit

Looks liek you either need to re-drill and tap the top tensioner, or contact gates belts and get them to make you a custon lentgh belt. The next size they do in 8mm HTD is 164 teeth which is 96mm longer than the belt you have now and probably too long?

    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
