Yeah, try the 10psi and if it freaks out, slap the 5psi back on or even that with the old stock solenoid dealy earthed to 7psi...

could be interesting indeed.

I've always wondered whether the Altitude difference between coast and here would make a noticeable difference in tune also.

Yeah will see how we go.

Hmm I had never thought of that. Might look into it. Hopefully it's not an issue

So this morning I topped up the coolant only to find that the banjo bolts on the turbo weren't tight enough and coolant starting leaking from them. Tightened them up to stop the leak.

But now the car seems to be overheating, or my cheap ass water temp gauge has crapped itself :/ Just at idle after a couple minutes the water is up around 80-90 degrees.

The gauge doesn't seem to drop below 70 degrees, even when the coolant is ambient. But when the gauge is up around 90 the water feels like it would be around that temperature.. My thoughts are maybe there's air in the cooling system. Tried to bleed it this morning but am unsure if its successful or not.

Found a couple fairly loose intake pipes but as far as I know there is no correlation between boost leaks and overheating?

Will have to continue tackling things later as I am heading down the coast tomorrow morning for the long weekend with some mates. Might think about completely flushing the cooling system and starting again

Air in the system

bleed the hell out of it

Jack the front of the car up...or face it up a decent hill

Use a coke bottle cut in half in the rad cap, and keep filling that bitch until no more air bubbles

Yep, never had to use the bottle trick but Uphill / Jacked front etc and cracking the Bleeder bolt seems good.

Yeah was reading different ways to do it this morning.. Do you leave the radiator cap on when doing that?

Nah, I leave it off and crack the bolts, the more places for air to escape the better IMO...

a few small revs helps to push the air out too.

oh and have the heater on Full Blast aswell.

Its nearly impossible to bleed it fully once.

You need to do it two or three times, each time making sure the bleed is at the top (usually car facing uphill) and yeah it has to warm up so the thermostat opens.

Theres another bleed at the back of the head, for the heater system. Its a total pain to get at. On my HCR32 its a rubber nipple like a closed off hose, on the heater hoses that run behind the head. You want the heater on hot so it lets any air through.

And intake leaks will make it lean under vacuum and rich under boost. Lean is hot and detonating. Bad.

I'm getting quite quick at doing this as I always have to do something to do with coolant. Jack it up as everyone said and stick a coke bottle. Let it idle and watch some TV. You may have to refill when the level goes down.

    • 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. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
