Possible Leaning Out? ~1 - 1.1 Bar On Stock Rb20t

Hey, basically my car was (safe) tuned and dynoed on 14psi with the stock rb20det turbo... mods are as follows : 600x300x76 PWR FMIC, microtech ltx-8, custom plenium,bov etc..

Car is currently running at 12psi just to be REALLY safe but I can smell the fuel!! too rich!!

Now, would it be safe to run at 15/16psi, Say if I ran 1.1 bar, would that lean out?? I know it's kind of hard to tell, but would an extra 1 pound or so be detrimental??

I dont really give a crap if my exhaust wheel goes by by, excuse for a new turbo..

I'd much rather that happen than my engine leaning out and going bang

It's definately running rich though

Would  you really want to risk it for just 1 or 2 psi? Go get it checked out I say. And the fuel smell you're getting can be leaks in fuel lines or a faulty fuel regulator.

14psi certainly wouldnt be a risk, as it was tuned at 14psi, and safely as well..

so i'm asking if 1 or 1.1 bar would be silly

i'm sure 3-4 psi would make a noticable difference, and if the fuel is there, i might as well use it

Go talk to GTRGeoff and RowdyR32, they've both had turbo's let go and shoot ceramic in to the ENGINE, you don't always end up with it just in you cat. Running ceramic turbine wheels to destructin is NOT a risk free exercise.

Also by 1 bar you're already past efficiency on a stock RB20 turbo, it's heating the air WAY too much to be a good idea, stick to ~12psi (spiking to 14psi odd) until you get a better turbo.

My 2c.

it's the exhaust gas temp kill the ceramic wheel, that's about tuning, it will make a different with good tune

i will say running 1 bar is fine as long as the tune is good.

run rich will make it cooler, which is good, keep it rich but throw in more timing ;)

lean it up will only cause yr turbo blow easier

    • Much less twat-tastic. CF wheels are too garish for civilised use.
    • From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)
    • In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird
    • Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller
    • So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
