Hey all,

I've build an RB30DET for the ‘lols’ (to replace RB30ET as head & SOHC wiring were damaged). I am using the stock tensioner & idler locations, with 2 tensioners (I am not drilling another tensioner so don’t bother saying it), I've test fitted the 151 tooth (part T307) from my other RB25/30 (which does have tensioner drilled) and its not quite tight enough for me to trust (but works fine), a comfortable tension causes clearance issues (by like 0.1mm), I reckon less 1 tooth should sort this out.

Has anyone else done this, and can they let me know the part number?

Cheers,

-Dan

Thanks, but both of those are actually for the T307 151 tooth belt.

It turns out that the belt I was after, funnily enough - had the part number: T306....

Cheers

This is a list of belts that i've compiled through comparing my new T291 belt to the stock SOHC dayco replacement belt for the RB30E. It fit exactly the same around the crank sprocket, so I did some sleuthing and cross referencing, and this is a list of belts that SHOULD be compatible.

When I say SHOULD, I mean that someone mentioned the GT2 to be compatible, and it was not. These belts are in comparison to the level of compatibility shown by the GT2. Even if you've got a GT2 on your DE conversion, it most likely does not fit as well as these ones listed above do.

    • Ok guys thank you very much. GCG highflow it is then 🙂 
    • forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k. 
    • neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.
    • Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock. 
    • Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
