Hey guys just wondering how much boost the internals of my series 2 r33 can take, I'm currently debating on which to do; hi-flowing my turbo or just get a new one but I want to know how much boost the engine internals and all that sort of stuff can take? And also what parts will I have to upgrade? I'm planing on running 10psi low boost and 18psi or so for high boost. Thanks heaps! Also what's the highest safest boost to run on the stock turbo since its ceramic I keep hearing different numbers I was running 10 pound but I put it up to 13 today just to feel the difference.

Keep seeing GCG and Hypergear, are they just companies who high flow the turbo for you? Do they recommend the turbine size and all that shit or you got to choose it? Sorry if this is a stupid question

Goals power wise I'm looking for some 250+kW at the wheels. Supporting mods, nothing at the present time apart from 3" cat back exhaust, pod filter, adjustable boost controller. However I do plan on buying splitfire coil packs and new spark plugs. As well as a new ECU, thinking of tuning it to run E85 but since I'm in canberra there's not many places to get it so I'll need it to be able to read both ethanol and octane. Budget is around 2-3k willing to spend more, just need more time to save the money.

Hey I'm new to sau, bought a series 2 R33 Gts-t and I'm wanting to high flow my factory turbo, I've looked through a whole bunch of threads but haven't really found any specific measurements for the diameter of the compressor wheel. I'm fairly sure the stock wheel is 49mm and I'm wondering how much bigger of a wheel can the housing fit? Also I'm unsure of the total height of it, if that makes a difference? Thanks heaps
