GEE120: Can you tell me more about the compressor surge problem?? I'm interested to know as we have been having trouble with a mate's setup with surge, you can hear the reversion noise really loudly, and power drops off markedly. You can even see the boost fluctuate a few psi up & down on the guage. His turbo consisted of a 13B turbo core & turbine wheel/shaft, Nissan VG30 exhaust housing machined to suit, & Garrett TO4B 'V' trim compressor wheel. The turbo builder took it back & machined a step in the compressor housing to alter the flow to the wheel, which didnt work, then went for a larger compressor housing, still surging, then finally a significantly smaller compressor wheel, still surging.
Now there's a factory RB25 turbo bolted to it, and the problem will not occur. The turbo builder is stumped by this, as he was sure the smaller comp wheel would fix it.
Good luck with yours! Hope its a more simple case!
CHeers
