Nice mod, took the car for a test run before the mod and after and can see the difference on the stock meter. Definitely feels like its pulling harder lower down.

This may be a dope question, but would it be beneficial to reset the stock ECU so that it might adapt to this change?

Can anyone PLEASE confirm if this works on a S2 Stagea or R34??

So far this question doesn't seem to have been answered anywhere in this thread.

Anyone??

actually to answer my own question, i went ahead and did it anyway.

I have a stock S2 Stagea.

All I did was cut the BLACK wire between the solenoid and the plug and then i connected the solenoid end of the black wire to the chassis.

Then I taped up the plug end of the black wire and also taped up the join on the other wires and the job was done.

And the result? At first I didn't notice any difference but the more I drove it the more I realised that the down-low response was noticably improved.

Top end power is the same, which was to be expected, but what you get is greater throttle response at lower revs. Makes it feel just that little bit quicker off the line :O

Too easy! and I highly recommend it!!

i'll try it on my r34 when i get it back from the panel beaters this weekend.

say, can anyone tell me what this would add to their fuel economy if they were to leave it on this setting all the time? i do about 80% city driving.

I used to get ~13-14 L/100km (100% city driving) - will let you know the difference next time I fuel up.

Worked sweet guys... took about 10 minutes to do. Now might be time for me to wire up a switch, but i think i might leave it on like that and see how fuel consumption goes.

At first, i didn't feel it, but then after some testing, my gauge was reading about 7psi before 4500rpm and i found highway driving quite pleasant :) . Great stuff.. thanks for this free mod.

There isn't much difference to fuel economy. Remeber, your accelerator pedal can also control the amount of boost. So unless you fang it 24\7, thre wont be much difference. If you do fang it everywhere...the difference is about 30KM's per tank

hey guys

did this over the wkend and definitely saw a change - I usually was getting about 0.45-0.5bar of boost and a higher rev range of 0.6-0.7bar. Well since doing this mod (and it is that easy just do the soldering, neat wiring stuff, and a good earth as mentioned!!) i've noticed a big increase in grunt in early gears - I can now shift off the lights at roundabouts and nip in thru traffic whereas previously the boost wasn't really helping to shift the car off the mark - its not massive but its definitely noticeable. cheers :(

just ordered a pfc off gr33ddy (paul) here on skylinesaustralia so looking forward to getting that :)

Question - this mod sounds great and all in theory, but surely grounding the standard solenoid permenantly means that it would be pulsing 100% of the time that the car is turned on? Including at idle and really low RPM when it doesn't actually need to?

Just a thought anyway...

For those interested - the Jaycar IEBC sounds like a better option in the long run if you're on a budget (like myself).

RaseR:

I think it just keeps the solenoid open permanently. either way you only see 0.7bar of boost on a normal gtst anyhow - by doing this mod you just make it see the extra 0.2bar of boost in the lower rev range which it would see anyhow if you gun the car hard enough in those gears. Its gonna put a little more strain on the stock tubby but they're good for 0.9bar I've read.

MMM:

heres a diagram I did for a mate elsewhere.... lookin at solenoid from front of car just snip the black wire, solder an extra bit to the end of the left half and earth it to a good point on the car - pref as near as possible like beneath a pod filter bracket which is what I did. tape up loose ends and try it out. its just a little wire mate :)

hey anthonymcgrath, that's exactly what I mean. Surely wiring the solenoid so as to be constantly on is not really a good thing, you certainly don't need it to pulse at idle and low rpm which it will do if it's permanently grounded....this would have to wear the solenoid at a far greater rate then something like the Jaycar IEBC......anyway.....

ah reet I see - In all honesty mate I dont know - I've just done it and I'll see how it goes - if the solenoid pops then I'll get a new un hehe :-/

i've just got a new turbo with a busted shaft which I'm gonna turn into a hybrid and I've also ordered a new PFC from gR33ddy for a great price off this very site which I should see next week.

Once all thats in along with other bits (arc intercooler etc..) I should see quite a hike in performance and a single stage of boost anyhow hehe!

I think earlier in the thread ppl mentioned removing the solenoid all together. not sure if anyone went with this route tho.

thanx mate for the info but i want to know if theres still anyway of doing it without cutting/stripping the exsisting wire

That would be the easiest way. Otherwise you would have to take apart the connector and not sure if it will go back together again.

Just buy some stripping wires and strip away (if your not sure. I stripped mine with scissors). It's piss easy. Soldering it on will take about 5 seconds. Cover it in heat shrink or electrical tape and your away.

I put a three way switch on mine....

Mounted on the dash so I can switch it off when it's raining.

    • 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.
