Girgor sent me a PM today saying about this.

Anyone ever heard of this being done?

I think this is how it goes....

Open the wastegate on the turbo and the exhaust gases should go out of that instead of spinning the turbo which stops making compressed air and results in the slowing/disabling of the turbo?

Does this work?

Does it do damage to your car in any way?

What is it like when the turbo does kick in if even?

Any info would be great as I'm a little confused

Thanks

What you said is right, goes out the wastegate hole before spoolin up the turbo, just not all of it.

No damage to the car just less air going in so ECU will fuel-up as necessary.

How you would do it i don't know?

Why would you want to?

Cool, ah it's just because I'm a inexperienced drive and would rather ease the boost of rather than start off with it fully boosted. It depends if I'll do it. If I can control the power than it will be fine and I'll just leave it.

Maybe you should of purchased a different type of vehicle if your in experienced? Like said above a civic.

exactly.. shouldve bought a civic... its ppl like u (not directly u) who go and purchase hipo cars without even knowing how to drive (any monkey can steer a car, thats what driving is about) and then go and get urself killed and other ppl giving the rest of us a bad name

u should sell it, and buy a civic champ b4 u do anyone any harm

i had a problem with my boost controller where it was holding the wastegate open when you changed gears. so in the next gear you would start to get positive boost at about 5500rpm. it was gutless. there is a hill just out of town where if i boosted it from the bottom i could normally hit 100kmh by just before the top, but i was boosting up it when i first discovered the problem. i hit third at about 80kmh and no boost. by the top i had dropped back down to about 60kmh. it was a pretty steep hill.

yes disconnecting the wastegate flap will give you no boost, but it will also make the car completely gutless. it would be like driving a natro that has done about 1,000,000kms and is due for a rebuild.

if you are really worried just disconnect the high boost solenoid. but it standard form they aren't that much of a handfull. i went from a manual magna to a stock manual 33 and was rather dissapointed. i thought it would actually notice a decent performance difference but i didn't. it wasn't until i started modding it that it actually seemed to have any go.

its just mate if u cant control the wow of a R33 gtst which in my opinion is a gutless overweight barge like all R33 then u have issues with driving.. how old r u..?

but having the GTST will make u learn quicker.. now try holding the right down at full sing in a GTR around a 40kph corner in 2nd.. and that is where ur schooling takes effect.

Yes, replace the actuator spring with something that opens at 0psi and then use a boost controller of some sort to make it run more boost when you want it. It won't damage the car - with no extra air going through the AFM the ECU will still find itself within its standard parameters. It might throw up error codes if it notices that its not boosting when it should, but in a pure "mechanical failure" perspective it should cope with being run permanently off-boost.

Of course, your car will drive like shit. You need to run a certain amount of boost to make up for the intake restriction that is the compressor and intercooler piping. The engine would run worse than NA if you set the wastegate actuator to open at 0psi. Couple that with the taller final drive from a car set up to expect more midrange, and you'll get something that even a Camira driver will think is slow.

But, as other people have said, if you don't think you can drive a turbo car then don't. You had another thread trying to get some kind of electronic speed limiter, and now you're trying to un-boost a turbo car. Have you considered that the common thread (and the easiest thing to replace) in all of your car-related problems is, well, you and your choice of vehicle?

not only the added restriction of the turbo and the cooler but the lower compression of the turbo motor. at 0psi boost even at 5000rpm they couldn't pull a drunk sailor off your sister.

just take off the hig boost solenoid, leaving it at 5psi. if the car is only stock and at 5psi you won't be much quicker than a commodore. if that is too much power then i can sell you a push bike.

I've always wondered about that phrase.

Considering how long he's been out at sea with only his hand for company, I reckon it'd be really hard to pull a lonely guy on shore leave off any piece of skirt that showed an interest and a pulse.....

And yeah, I forgot about the compression ratio thing.

yeah i always wondered too. it is a bit like "cheap at half the price"........ most things are cheap at half the price.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
