Hi guys

I recently bought my first turbo R33 so far im loving it but i have a few concerns and hoping someone can help this newb!

when i first got it i noticed the stock controller wasnt even connected... after connecting it it seems to be running about 20psi. Any ideas on how i can reduce this? or why it may be running so high?

I bought a manual Boost controller and fitted it instead running only about 9 at present but of course im getting a severe flat spot. ive been told an ECU reset can help fix this? Im planning on getting a proper dyno done on it after xmas but any suggestions i can try before then?

Thanks for all help!!

Sounds abit weird. Any strange noises when you hit boost? cos if it is standard turbo running 20psi thats not good. As for proper dyno tune you will need PFC, nistune, etc.

Edited by Shazza24

where are you reading 20psi from? is your gauge in PSI or something else and you are getting mixed up?

if its a legit 20psi, and itsreaching 20psi its running unlimited boost, which will kill the turbocharger and probably the engine

stop driving it, fix your mangled boost controller install or get it done by somoene who knows whats going on

the engine and turbocharger are at severe risk like this

until you fix that, dont change anything else, ie dont fit an ECU to "tune" around it

once you fix the boost control issue, you should have around 12psi as normal max boost on the std turbo

check that all the hoses for the stock boost controller are hooked up. I've never heard of one failing and doing that. Theres a DIY on how to earth out the solenoid to run constant 7psi, it should have some photos of where all the hoses should hook up to

Perhaps i should clarify i bit more...

i have a gauge in the car.. its reads BAR not PSI (came with car) ... when i have MY manual boost controller connected i have adjusted up to 0.7 bar (10psi according to the calculator) thats running it in 3rd/4th gear highest revs.

When i disconnect my manual controller and connect the FACTORY controller my gauge hits 1.5 BAR (20+ psi) in 3rd gear at about 4000+ .

I want to run my manual controller over factory but should i be worried about the factory one running so high?

Thanks again fellas

ps. i can take some photos tonight and post them with both setups if it helps?

it sounds like when you unplug your manual control you are leaving somehing disconnected, or connecting it backwards

which means the wastegate never opens, thus unlimited boost

you did plug the standard boost controller electrical plug in and have checked for damaged wires to it? Im pretty sure if it was just left disconnected but it would just run 5psi all the time

disconnecting the power to solenoid wont cause harm it run just run std actuator boost

BUT disconnecting the VAC lines or connecting them the wrong way means the actuator may get no pressure signal

no pressure signal, the wastegate doesn't open. the wastegate never opening = unlimited boost = engine failure

yeah sounds like you may have connected the line that goes to the BOV return line (if your still using that) or the line for the boost presssure (from cooler pipes) around the wrong way

theres 2 ports on the solenoid, one for each, then the one that goes to the wastegate. Im pretty sure anyway?

    • I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k . 
    • Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?   
    • Yeah I've spotted this one too, whenever it's lotto superdraw week and I'm browsing car sales dot com for my new ride They must be dreaming, maybe it's worth 150k for the link to Brock?
    • 100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!  
    • ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
