you shouldn't mess with your emissions setup. besides, it won't give you any power increases your pcv has to be venting, you can't just block it off. bring it back to stock and i bet it fixes your problem. -wombat

sounds exactly like an over-pressurised crank case - blowing oil past the turbo seals and piston rings. i bet after you've let the engine gear down running down a large hill and then pulled away, white smoke just plooms... just make sure your crankcase can vent correctly, check your pcv and rocker breather valve are connected and free of any major restrictions and that your pollution gear (carbon canister) is connected and not leaking. only a handful of things can cause that kind of smoke and almost all of them are ruled out because you have just rebuilt your engine. white smoke in your situation is indicitive of oil being spilled out post-combustion and smouldering (white) on hot pipes. the only thing i can think of that wouldn't be a pressurized crankcase (and isn't exempt due to the fresh rebuild) would be your turbo seals. unless your hks aftermarket turbo has done more than 100,000kms or has been run at more than 20psi for prolonged periods, i would first be checking all your emissions equipment and making sure it was all in order. first thing i suggest is connecting ALL hoses as per factory specifications. then, if it solves your problem, recconect it all one-by-one until you find the smoke-causing culprit. all the best mate. -wombat

out of sheer curiousity, do you think it would make a good upgrade for the vl turbo? -wombat

thanks heaps for that info guys - most appreciated just curious though... how much bigger is the vl turbocharger over the rb25 unit? does it have the same ceramic blades? -wombat

hi all, cause vl turbo parts seem to be cheap sometimes i figured i'd ask this one... is the rb30 exhaust manifold the same bolt pattern as the rb20/25 one? can i use the vl t3 turbo as an upgrade on the skyline? and can i just buy rb30 extractor gaskets instead of ordering in the rb20/25 ones? thanks all in advance -wombat

i tried to send a pm but your inbox is full so it won't send. do you have a mobile or email or something? -wombat

how many psi do the rb25's run stock? do you still have the actuator for the 25? -wombat

how's the condition of each of your turbos? how much shaft play in each and how are the seals? did either of them (or the engines they were attached to) blow any smoke? -wombat
