Hi,

After doing a bit of research and reading over the converson guide I have found the following belts that can be used for the RB30 conversion.

Dayco

Part Number 94407

From Mazda 323 1.7lt TD 1986-1996

152 teeth x 1" (25mm)

Can be purchased from Repco for around $40

Gates

Part Number T291

From Audi A4 1997-2000 1.8lt 4 cylinder turbo

152 teeth x 1" (25mm)

Can be purchased from Repco for around $70

NB: Part Numbers T175R from RB30 will not work as it is only 115 teeth. GTR timing belts will not work as they are 141 teeth.

There is possibly a Bosch belt that will also suit but I am unsure of the model number. There is no reason why any 152 teeth x 1" belt wouldnt suit this conversion.

Hope this helps...

      Theoretical Power Numbers

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).

      @Murray_Calavera nah, not available yet, they're gearing up for it but won't be available for a few years. So you reckon fuel is the main issue? When this bottom did over 600rwhp it was running big single, twin Z32 MAFs and believe it or not, e manage blue, an old school piggyback 😅 not really a fair comparison but I guess it shows how a big single differs to smallish twins.

      @Darrel Can you get pump e85 where you are? If you want to max out those turbos, e85 + bigger modern injectors will be the easiest way to get you there.

      Hi @Butters , thanks for your reply. Pump 97 BTW but yeah, I get that old tech is what it is and can't compare to modern stuff but I still believe 500 is achievable, even with these smallish twins. Their effective limit is around what, 24 psi? Intend to go single one day but then again, I'm not chasing big power and might not be worth the investment. Just wondering what if any factors are limiting my setup after a few changes. Let's call this Dyno 02. This is after R35 MAFs, 720cc injectors, DW300 FP, HKS step 2 264/264 cams.
