Hey Guys

I am stuck at the moment my car getting about 280-300kms out of each tank its making ok power (175kw)but is runnin very rich. The guy who dyno'd it just said its been tuned for more boost so I can use the fuel of a high tuned car and have the power or use the fuel and not have the power.. but I'm not so sure he's right! he has a pretty bad history with powerfull cars that don't live to long how much boost can a stock skyline handle with front mount and 3 inch turbo back system ?

The car may have different internals but I'll play it safe as far as i no the turbo has a steel front wheel. maybe the plastic one fell off??? (series 2 r33) haha

it also had a heap of wiring pulled out of it once it landed in australia. what other things can make it run rich?

The car feels great to drive and doesnt show any signs of problems!

it all comes down to how he tuned it.

noone is going to sit here and say 'run 12psi' then have your motor blow because your car is tuned for 7psi (example).

that questions can only be answered by your tuner. he sounds shit so i'd be taking it somewhere else and get them to do it all for you.

well the front wheel of the turbo isn't the problem, its the ceramic exhaust wheel that all rb25's have the problem with. if it has a steel wheel and is a series 2 (unless it is a 95 model, which makes it a 1.5) then there is the chance it has been highflowed, or just replaced with a series 1 from a wreckers.

as for the car running rich, that is how they are from the factory. and your fuel economy is about right. when you say to a tank, how many litres do you mean, beacuse some people fill up at the empty line, others fill up at 1/8th of a tank to go and still say they got X amount of k's to a tank.

na I mean fuel light comes on i fill it to the brim and 280-300kms later the lights on again the car was tuned in japan by ksp tuning I can't get info off them it could have been done 10 years ago. So i'm just tryin to match the ecu and am not sure if I should just hammer in the boost, I don't drive the car very hard I have friends with skylines making 240kw that use less fuel? but do have better ecu's and mods...

Boost wise whats "safe"....? will the turbo be the weekest point? or engine?? :O

with my air/fuel haeding into 10:1 do you think I should just go new turbo for more air???? I can get my hands on a to4 but I'm not to sure if I want it I think it will be real laggy and I don't want nothing till 5000rpms.

I only want around the 220-250rwkw wat turbo will give me this without to much lag??

Cheers! :D

If your cruise mixtures are all rich then possibly look at getting a stock ecu fitted or even a new 02 sensor.

If the car is tuned properly it should not run rich everywhere. The idea that you have more fuel in than needed at a specific load point because it is tuned for more boost is ridiculous, as when you add more boost the ecu will be looking up a different point in the map (which i suspect will also be a bit on the rich side).

    • 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.
