Yeah seems to be a bit of luck involved. I've hammered 10 pr 12 laps around Wakefield at 1 bar without hurting the turbo (spat a few other things though). Don't have a FMIC either. Other people spit bits of their turbo out at .81 bar. Go figure.

been running my 32 with exaust pod without touching the turb and it went to 11 psi just from that now its got a bleed valve to set it to 14.7 switchable and she is running nice and hard all day every day.

Then again im just waiting for it to blow so i can get a 2540 :)

I am looking to boost my GTR and waant to know is it always the case that all debris from the exhaust wheel goes down the exhaust pipe or is there ANY chance of any bits entering the exhaust ports. I can probably live with the replacement cost of a turbo but don't want to stuff the head/valves etc.

i was told if u back off it can go back in the motor ?

anyone know?

ed,

wasnt aware that 32 turbos are a bit more heat resistant. :D kinda happy about that i must say, though i  still want  a 2540 on it.

Its not that 32 turbos are more heat resistant, Its more the fact that the rb20 produces less heat to the turbo than rb25

Its true that a steel wheel will take more heat than the ceramic one. But if you take a RB25 turbo and put it in a RB20 you will be able to run more than 14psi that is possible in its original application.

I did not know that the RD20 turbo had a steel wheel? Why did nissan go to the ceramic one? Maybe for a quicker spool up yime or something...

The biggest mistake people make with bikes, Karts, and cars is forget the guy who designed the thing had a fair idea.... After all he earns a heap of Yen and would be out of a job otherwise.

Safest boost level is standard... end of story! It allows for fuel variables, worn engine components and is working with its mate the ECU who was born the same day.

Additional boost = additional performance. and the reliability is inversely proportional.

That is why most performance mods are sold as a package... and considering you can hardley notice <20kw, it becomes a game of chance, you decide at what level you wish to play...

Good Luck

    • Have you tried another indicator stalk? Sometimes these go bad and cause issues.
    • They're so beautiful 😍
    • Early last week, I became concerned that the car was feeling....slow. Most of my driving is commuting to/from work and there are few opportunities to get up it and convincingly make boost/power. It drives in vacuum almost all the time. But when you do occasionally get an opportunity, and.... it takes a little longer to start making power, and then there's not as much as you'd expect, and then you run out of road anyway and have to bottle out - it can be hard to be convinced that there's something wrong. But by the end of the week I was pretty convinced. Made an effort to get a decent test run. Took bloody forever to come up on boost and when it did it would only make about 50 kPa of pressure. There was no black smoke, no noise of a boost or exhaust leak, no evidence anywhere of an intercooler hose clamp being sloppy enough to let air escape. So.... not that sort of problem. Brainstorming led to thinking that the boost controller's solenoid might have failed in some way. No active boost control would just give wastegate pressure, which I was more or less getting, and the laggy behaviour could just be "normal" shitty boost response from an uncontrolled highflow. But a little extra 3rd party brainstorming led to the thought that the actuator circlip might have jumped off leaving me with a bluetooth wastegate. So, on Friday, off comes the stock heatshield (which is an annoying enough job on its own) to reveal - yup. WG is wide open. And.... it won't come back. It is jammed in the dump. Put the rod back on with a new circlip and tried driving it to get it hot in the hope that the capture was from thermal effects having been blown into the dump when hot and since cooled. Nope. Won't move, even with screwdriver mediated force when hot. Ran out of time to play. Came back to it yesterday. Unbolted the dump. Was lying under it with the dump jammed up against my guts undoing the bottom 2 bolts. Got them most of the way out and gave the dump a serious heave. It didn't noticeably move, but there was a satisfying "plink" noise from up to. Shuffle out and sure enough, gate is now closed. Nevermind that there was still the better part of an hour after that required to put it all back together. f**ken cars.
    • For your application, where you'll be at that 1/2" size or perhaps larger, yeah, excellent. Although not if you need a tight bending radius anywhere, because the corrugated stuff is not anywhere near as flexible as rubber/teflon cored stuff. But for turbo oil lines? No. Too big. They just don't do the corro stuff down at the ~1/4" ID size that you'd want, and if they did the OD of it would probably be a bit too fat for fitting it into the tight spaces available. I use hoses like that all the time for fuel gases (LPG, NG) and liquid fuels (HFO, diesels, waste oils). When we did the London Olympic cauldron, with the 204 individual burners on it, we had miles of the stuff (although a lot of that was teflon core). A bunch of that crap is still cluttering up the workshop, more than 12 years later!
