Umm, fragile 12-15years old ceramic wheeled turbos a good enough reason? ;)

yeah, i did...then i spent a few grand on a new set of turbos... :(

restrictor is good i thought coz it allows to run .7bar as a minimum instead of .9-1bar minimum...

The problem is, its impossible to say (with any accuracy) if the ceramic wheels will definately let go or definately be fine once the boost restrictor is removed.

My 0.02c is don't remove it unless you are happy to run the risk of blowing one or both of your turbos. If they blow, your looking at about 2000-3000 in parts (for new items) plus installation. Of course if they blow and take out your engine, your up for double that.

That's a rather expensive risk to take in my books.

when you say it like that its probably not worth it hey

i was thinking is it woth the effort of taking out the restrictor as to how much more power you will get lol.

1st gtr i took it out.. and it went fine and still gets around fine these days

2nd gtr - it was out when i got it.... the motor has now died however the issues arnt directly related

3rd gtr - its in and staying in as long as i have it

i guess i just mean, taking it out will give notable gains, i wasnt really concerned of the risks when i did it because i didnt add up the costs etc.. also in a HPI mag i saw a write up on how to get more power from a gtr, they did it to there gtr and the results sucked me in

can u put it back in if u remove it????

lol :lol:

i just had a huge argument with a couple of people about this sort of thing..

see thread> why was my GTR running so much boost. mainly the last page!! :P

ps. for temporary solution disconnecting the hose the the boost solenoid will result in running stock boost (if no boost controller is installed)

now i have started it here! :lol: sorry guys

my turbos have run over 40,000ks, a few track days at 1-1.1bar boost making 260rwkw. I'm back down to 0.7bar now for unrelated reasons, and its so slow!

But it is luck of the draw, some turbos may die at 1bar, some may last forever.

      rb20de neo +t conversion - boost pressure sensor needed?

      By Neostead2000 · Posted

      Agreed with the rest. Also at least based on my own research, there are no readily available stock or close-to-stock RB20Neo maps that you could download and use as a base were you to buy a complete standalone ECU, and the regular 20DET maps don't really work well so you'd need to take it to a tuner if you have no experience. I installed an AEM V2 on my 20Neo+T and had lots of headaches until I got it to run and idle properly but I've yet to remap it fully. You have to start building up your timing and fuel maps entirely from the ground up; even the ones for a 25 didn't work at all.

      GOT SUM's RB34

      Got some decent progress after work yesterday and also today. Got the ECU all wired and passenger side interior all back together. Kept the wiring up nice and high to avoid people standing on it. Got the surge tank relays rewired and tidied up the pump wiring and cut a hole to bring the cables through.  I found a spare USB cable I had lying around so I decided to cut it up and see if I could use it for my CAN 1 bus. Turned out one of the pins I needed was to the shield of the cable so i cut it up and desoldered it and resoldered to the correct pins.  Had the issue with the powersteering hose hitting the A/C compressor and fan shroud. I pulled the bracket off and modified it to remove the front mounting point which now clears it all. Will keep an eye on it to see if theres any signs of fouling once it's up and running.

      So today I went well outside my comfort zone (again) to replace my valve cover gasket.  I have had a big leak over the exhaust leading to a lot of smoke and smell every time I drove it. The leak was in the rear driver's corner.  The job wasn't hard as such, just a bit finicky and time consuming.  The old gasket was rock hard and broken right where the leak was.  The leaky corner had so much sitting oil in it.  The good news to my amateur eyes was no buildup or sludge under the cover. It all looked fairly nice in there.   I haven't started it yet. I ran out of light and body when putting the coils and injector loom back in. Probs only 30min left for the morning.  I was so nervous putting the cover back on, I must have lifted it 5 times to make sure the gasket was still seated properly. God it's going to be nice to be leak free and not make other traffic light queuers think my car is about to explode.
