G'day guys,

I know this is a very repetative topic "whats the max boost I can run?!?" :D

but I've heard that R33 Series 2s have plastic compressor wheels ... and my friend is wondering how much boost he can run :confused:

He only has a catback zorst and the bleed valve :D

Should he just set it at 10-11psi?

Cheers :)

The Nylon Impeller turbos were brought out in the R34's

Regardless though, the weakness is the ceramic turbine

I have a series two and have boosted mine to 13psi, although, i have a very efficiently cooling intercooler (~8degrees above ambient temps) and tuned properly

Running stock intercooler your best bet for your mate is 10psi in which case would most likey be at if he was to get a turbo back exhaust (so there will be no need for bleeding)

dont bother with bleeder valves or such, just tell him to get a dump/front pipe from the turbo and the boost pressure will increase natrually to 10psi

So Soulja, your engine is so inefficient that you have to run 32 psi to make any power. Get a decent engine and turbo and tune it properly so you can make the same power at 20 psi. Just like dinosaurs, big boost is ancient history. Get with the new millennium or you'll be extinct as well.

i doubt he even has a car! :bahaha:

back to topic. i agree with above.

do the full zorst fron turbo back/hi flo cat.

I get 9.5 psi and that's with my huge cooler.

12psi is the max. You can crank it to 13-14 but your turbo is not gonna last very long... curse the ceramic!

I just put a full turbo back system on my 33 ser2 and boost is hitting 10 psi now instead of seven.. An it jut ayers coughing an farting as soon as it hits 10..

Anyone able to tell my how it could have changed my boost pressure an why it's not likin 10 psi?

Other mods being

Walbro fuel pump

Fmic

An have disconnected the 2 stage solenoid by earthing it..

    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
    • Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
