hey fellas i'm very interested in doing this mod on my car i just dont know enough about

i had my mechanic do an aftermarket boost controller on it but i think its stuffed and its spiking and i'm overfueling cause of it.

help please

get the mechanic to put it back to stock boost control solenoid/setup then just ground the black wire between the solenoid and plug, seriously its that simple (or tell im to do that) ie cut it and attach it to car body - ground

or even grab one of those turbotec boost controllers in forced induction section $22 thing if u want a few more psi

my r33 just used to sit on 5 psi never went any higher so dont know where the 7psi side of things went but did the mod today took all of about 10 mins and now it goes to 8 psi comes on quicker pulls harder than b4 im rapt mid life crisis

Ok this may seem like a stupid statement,(As i dont actually own a skyline yet) but i always thought that if you upgraded ur exhaust, say 3" turbo back, ur boost automatically goes up. In saying this would this mod still work? Please detail ur answer as im new to the turbo/skyline scene....LoL

Cheers

this mod will still work. boost is a resistance to air, take out the resistance aka bigger exhaust and boost will go up a little as there is less resistisance, so it can flow more but the mod will still apply

wouldnt the wastegate actuator stop it from going over a set psi regardless of the size of the exhaust?

Thats another thing i was thinking but didnt wanna say...

A larger exhaust (more flow) allows the turbo to spin up easier, and as such faster, here in NZ we rip the insides of our cat convertors out also to create less back pressure...

Yes Yes Yes....I realise this BUT will the actuator/ecu/solenoid etc stop it from gaining the 'automatic' boost you get as a result of putting a bigger exhaust????

I realise the effects of a bigger exhaust on a motor/turbo but will it be electronically restricted?????

well, when i first had the rb25det in my R31, i had the stock 1inch exhuast, and it would only make 5psi of boost, when i put on a 3inch turbo back it did the 5psi, then 7psi after 4000rpm but that is all, the actuator will stop anymore boost from being made. I also install one of them $30 boost controllers, its all pretty damn fine now.

I did this mod last night, and bang me dead its awsome!

can anyone tell me what having this loop does(drawn in red)....cuz in my car the solenoid has a loop...the top one doesnt go where its supposed to go....i need an explanation on what this does....esp cuz am a newbie to skylines...he he ;)

wouldnt that be done just to plug up the solenoid..?

the bottom one runs to your wastegate actuator, without this you car will probably boost until the fuel defender cuts in

the top one should run to your inlet piping after the air filter, i blocked mine off (top one) but have since unblocked it and it makes no difference

My setup is abit different from everyone else's. Is it still ok to do this mod since the 2nd solenoid nipple is being used?

And if so, which wire goes to ground, white or black?

This mod looks great!

Just thought I'd ask if anyone had successfully done this on an R34?

I would guess that it would be almost identical procedure?

I have noticed that on the R34 boost is limited in 1st and 2nd gear, getting the full dose in 3rd through 5th. Would this mod "rectify" this boost cut in lower gears? Thanks guys!

Never mind - i've sorted it myself - i've purchased the following:

http://dseau.resultspage.com/search.php?p=...34&site=&w=7701

for anyone that doesn't know anything about electronics you need a SPDT switch which is the following:

SP = Single Polarity - DT = Dual Throw - which pretty much means that if you flick it one way 1 thing turns on - flick it the other way the other thing turns on..

good luck!

Just purchased one of these things and about to give this a shot.

On the back it's got three pins. 1. 2. 3.

is it

1. Wire leading to ECU

2. Wire leading to actuator

3. Wire leading to ground

Have I got it wrong?

    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that.
