is pumping the stock turbo up to 10psi a bit or a risk? as far as i am aware, 10psi is the absolute max you can push the turbo to (correct me if I am wrong) and i would not want to be driving with a turbo that is stretched to its limits.

Hearsay and conjecture.

Depends on which stock turbo..

25s2 and neo turbos have the nylon compressor wheel which likes to delaminate when leaned on too much.

rb20 turbos, mine took a beating on 14psi for about 6 months before I sold it

25s1 turbos (with steel compressor wheel), mine was on the RB20 @ 12psi for a year and has been on the RB30 @ 12psi for a year aswell. On the 30 it's choking up something chronic (which means it creates excessive heat too) and it still hasn't shat its' exhaust wheel..

hey

i got a manual boost controller but im not sure how to set it. can someone set it for me[was told i need a boost gauge to set it properly] only want it running 10psi

thanks Sunny

sunny i have a spare boost gauge you can borrow if you want

set it all the way down, then 4 clicks up... thats where mine is set, n im running just under 10

which part of 'no clicks' did you not understand?

and 1 turn != 1 psi, get a boost gauge and find out exactly what it is doing, otherwise you might be hunting for an exhaust wheel in your cat.

my RB25 turbo was on 13psi for the 3 years i had the car, plus however long before i bought it, and only gave up when the engine threw a leg out a bed, and presumably crap though the turbo.

Guys guys guys.

NOT ALL RB STOCK TURBOS ARE THE SAME.

RB25 seriesII and RB25Neos can't handle as much boost as the RB20 and RB25 seriesI turbos.

I really wouldn't be pushing a nylon compressor wheeled turbo past 10-12psi.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
