SIKR33

On the internet, as in real life, there are certain rules that people should follow - in this case, they are referred to as 'netiquette'. Here are a couple of links I found by typing 'netiquette' into Google:

You will note that typing with caps lock on, apart from being annoying to read, is considered as shouting on the internet, and can also be considered rude in some circumstances.

Noone is suggesting that you're an idiot or anything because you use caps lock - in fact, I think most of us appreciate you taking the time to post up little tidbits of info like that in your top post. It's simply more pleasant to read something that's written in lower case or, preferably, mixed case (proper capitalisation). Please don't bite someone's head off because they have the nerve to offer constructive criticism.

Please, PLEASE, turn your caps lock off. Think of it like the indicator on your car. It isn't absolutely necessary to use it to go places, but it sure as hell makes the trip far more pleasant for those you encounter along the way.

OH OK YOU MUST HAVE SHITLOADS OF TIME ON UR HANDS OK

[Revhead]

Yes, I had a spare five seconds to look up that info. It shows a huge amount of immaturity on your part for attacking people who have a simple request, like pressing ONE KEY on your keyboard. All of 23 posts to your name and already stirring shìt.

[SIKR33]

OH OK MR MATURITY WHAT EVER YOU SAY

[Guest 570CK]

hahaha amusing

Btw, he's right about the "RESTRICTOR"

And its not gonna blow up your motor only increases your boost by a few psi.

[Guest INASNT]

Aircraft mechanic?? sure u are

[Guest 570CK]

btw, who cares if he uses caps. Just read what he has to say, or if ya don't want too, then don't read it.

[Gradenko]

570CK, I've read what he has to say and its useless info. As a FYI, I went out to my garage and fondled the hose's going to the solenoid that I'd previously removed. No restrictor. Its a well known GTR tip, not one for the 25t.

Can a mod please, please ban SIKR33. Every post I've read from him has been useless. Every sugestion to him to not use caps has been ignored.

this is getting quite interesting.. keep going guys..

[WazR32GTSt]

anyone got more info on the location of this restrictor? or some pics?

does it restrict air before it enters the turbo or boosted air after it leaves the turbo? coz if it is after then it will probably up the boost won't it? And for soemone running on 10psi (me!) that could mean turbo danger in the future if you rise again.

[Revhead]

I don't think you're dazzling anyone with your intelligence. Ignoring and subsequently attacking people with an incredibly simple request is not a good way to make friends in here.

Anyway, getting back on topic, a restrictor in the wastegate line, particularly after any boost controller, can only slow the passage of pressurised air, thereby causing boost to come on harder and possibly with a small spike. Surely removing it will slow boost response and remove any short spike in the boost curve? So, without some form of EBC or at least a gated bleed valve, the car will feel more sluggish. With an aftermarket controller, you don't want a restriction to affect the function of the controller so in this case, go for it and remove the restrictor.

hahah yep it is

[rev210]

I have removed the so called 'restrictor' in the past.

It does nothing to an R33 is all I can say, but hey knock yourself out it won't harm anything.

Yep is does cause the boost to spike

Hey guys, the point that needs to be acknowledged in this discussion is that it only applies to the GTR. For people who think that it does not increase power, your wrong.

Last week I was told by my tuner/mechanic who specialises in GTR's said that he was surprised that I still had the restrictor in, apperantly it's the first thing you do when buying a GTR (remove restrictor), and it DOES NOT harm your engine or turbo.

Anyway I had my car tuned on the dyno and it went from 185 rwkws (stock boost) to 215 rwkws with taking out restrictor and installing adjustable cam gears/dialing in cams. Boost increased to 13.5 psi, but only held 12.7 psi through high revs. However Powewr FC with boost solenoid and hand controller are going in in the next few weeks, to increase boost to 1.1 bar (apprx 16psi) and lean out the fuel (was running 10.8 a/f ratio). Power should increase to 240-250 rwkws.

Therefore by taking out restrictor it increased boost from approx. 9 psi to 13 psi. Definetly a power increase there.

Just thought I'd shine some light into the discussion.

P.S Other mods incl full exhaust (3'' high flow cat), Apexi pod filter kit, oil catch can.

good to see some people with some brains on this site

228kw on a 200 would be damn fun!

[SIKR33]

guys if you dont believe me ask the guys at tilbrooks auto and dyno theyre the guys who told me to remove the factory retstrictor and seriously i have had no problems here the car goes like a shower of shit AND YES i am a licenced aircraft maintenance engineer i did 6 1/2 years in the RAAF in ardu

AIRCRAFT research and DEVELOPMENT uNIT BASED AT raaf EDINBURGH sorry guys i know a hellava lot more about jet turbines did my basic training on turbo charged aircraft engines

so believe what you want gredenko and inasnt

dont like what i write well F%^k u

[Gradenko]

Unless Nissan started putting RB26's in the series II (and did a damn good job of disguising them), you ain't got no restrictor. I don't know what the hell you've been pulling out of your engine bay to make it "go like a shower of shit", but it sure as hell wasn't a restrictor.

Wait! Maybe you turned your back on the car one day and someone dumped a RB26 in there for you. That would explain it!

[SIKR33]

ha ha very funny man so ur tellin me that tilbrooks don't know what heyre on about i would believe them over you PAL

[Gradenko]

Dude, don't believe me. Believe the vacum hoses that came off my car.

Name dropping hey. Well then, that backs up everything you've said. Two can play at that. I just got off the phone with HKS Japan, want to know what they said? They said you should stop waving your dick about in forums. The 25t has no boost restrictor, you probably misunderstood what ever it was tilbrooks was trying to tell you. Adding a restrictor (in the right place) will increase boost however.
