Timtam72 Posted December 16, 2014 Share Posted December 16, 2014 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.

There is no set number anyone can offer you given the variables from setup to setup, engine and turbo age, fuel type, tuners ability etc etc... Stock turbo's dont generally like too much boost for too long... I run 28psi through my stock engine and it gets punished on the track pretty hard... In saying that i have done every supporting mod possible, the only thing i havent touched is the internals really...

zebra Posted December 16, 2014 Share Posted December 16, 2014 Has nothing to do with Boost What do you think will be harder on the motor A GT55 at 10psi or the standard turbo at 10psi Link to comment https://www.sau.com.au/forums/topic/451798-how-much-boost-can-r33-internals-handle/#findComment-7445095 Share on other sites More sharing options...

Dose Pipe Sutututu Posted December 16, 2014 Share Posted December 16, 2014 I thought it was 42? add some octane booster gives you free boost Link to comment https://www.sau.com.au/forums/topic/451798-how-much-boost-can-r33-internals-handle/#findComment-7445226 Share on other sites More sharing options...
Badgaz Posted December 16, 2014 Share Posted December 16, 2014 its not really the pressure of the boost you have to worry about...its the pressure caused by the explosion in the cylinder...

hypergear Posted December 16, 2014 Share Posted December 16, 2014 At optimum ignition advance, the factory engine head starts to valve float around 22psi. Neo motors don't seems to have this problem tho.
