Hi everyone. Took my car down to Sydney Monday morning to Dart Automotive in Punchbowl to have bigger injectors and Power FC fitted as well and then tuned the Next morning. they also did a spark plug and oil change for me and I cannot speak highly enough of the good, friendly, honest, well priced service Jim and the guys at Dart gave me. I had to book my car in at very short notice (last Wednesday) due to another unnamed workshop stuffing me around at the last minute and having already booked non refundable accommodation in Sydney. I am very very pleased with the results of the tune etc. The car had only 3" apexi exhaust from dump pipes back and hks electronic boost controller, factory fuel pump, factory airbox and factory turbos when I took the car to Dart and it made 179.9kw at 4 wheels. After injectors and power fc were fitted (still using factory fuel pump, airbox and turbos) the car now makes 280.1kw at 4 wheels at 1.15bar. I am more than happy with the results and it is a totally different car to drive. I used well over a quarter of a tank of fuel less on the drive home too. I also had an upgrade fuel pump to fit but Jim said I'd be wasting my money with as the factory GTR pumps are very very good and capable of well over 300KW which he could easily have said I needed as it would mean more money for him to fit. I would recommend these guys to anyone and will definatly go back to them for any future upgrades.

Did they comment on the reliability of the turbos at that boost, and what can happen if they fail? If not, they did not do the right thing by you IMO.

Did he offer an opinion about the reliability of 10-12 year old fuel pumps?

Nice result after all the messing around you had!

As I said via pm tho, that much boost is asking for a dead motor for the sake of 20rwkw, I strongly urge you to consider lowering the boost to a safer level for longevity of turbos, and in turn your motor

I have known Jim for many many years and thought he was a little smarter than that

1.15 bar of boost on a ceramic turbo is destined for failure.

Give him a call and make sure thats what it was actually tuned for as the colder weather may very well be causing it to over boost out on the road.

Oops, correction... car was making 219.9kw at the wheels before computer and injectors. And the car was running 1.15 bar on high boost setting when I bought it and who knows how long for as exhaust and boost controller were on the car in lap

Oops, accidentally pressed add reply before I was finished. Exhaust and boost controller were on the car in Japan. And yes he did mention the fuel pump being 12 years old and said that if need be he would put my walbro pump in but factory pump is performing fine and probably better than the walbro anyway. As for the boost I'll call Jim and ask him but I imagine he has done enough tuning to not do something that's gonna cause damage.

wouldnt worry about your boost too much. Its a long on going debate.

I would comment on how long my car ran standard r32 turbos for (at more then 1 bar) which arnt as good as r34 units but it would just turn into a shit fight.

Basically, trust your tuner, hes probably done a lot more cars for a lot longer then keyboard tuners on here

im running 1.2 bar on stock R34 GTR turbos & made 247rwkw~

it lasted around 6 months (still going tho) just the seals are letting go and oil is leaking through and ending up leaking out of the air filter :(

gonna lower it down to 1bar till i save up enough $$ for -7 or -9s lol

good luck, i hope it doesn't blow a comp or turbine wheel on ya.

id change the stock fuel pump to something new. you can sell off the stock pump quite easily also.

^^ agreed, a fellow member on this forum and sau nsw member ran 21psi and only pulled 262 or so @ CRD.

well I guess everyone is entitled to they're opinions but I'm happy with the way the car is. Jims dyno is apparently de-tuned 20 kw for race cars or something so power readings are 20kw less on paper than actual power figure. So car On paper was 199kw before and 261kw after but Jim said actual power is about 280kw. Totally different car to drive and big difference In power. I can definatly feel the increase and was told car could have been pushed even further but he kept it safe. The power figures are on paper And I will post them soon. I'm not saying anyone's opinions or suggestions are wrong. I'm happy with the car and Jim definatly seems to know what he's talking about and doing so I have faith in his work aswell as researching positive feedback from others who have used dart before I went there.

Its one thing to be happy with the car now, but how happy are you going to be when the turbo falls apart...

I have seen R34's make 280rwkw on standard turbos whilst i was at Advan. Cant recall how much boost it was running though as it was many years ago.

260 is much more believeable, Sif claim it was 280 if the dyno said 260!

And to surcam, who cares how much you were running?

Have a read of the engine fail thread, or other threads about dead 26s

Whilst the turbos might not fail in every single case, some might be fine for years, there is enough information & users to prove turbo failure can kill your motor if they let go.

Bit silly IMO to want that extra 10-20rwkw with the extra 2-3psi when it could cost you a 5-8k rebuild, not worth the risk at all. But then some places don't care if it kills a motor in 2 years time as they can then blame wear and tear, and make a lazy 2-3k outta a motor rebuild etc.

(DISCLAIMER before e-rage: Not saying this is what Dart have done)

It's both shaft speed and heat. Also #6 runs a bit hotter and hence its usually the rear that goes.

I wonder what shaft speed is influenced by...

But riddle me this, its a 10+yr old car with a history you can't say was always say was safe... How do you know it will be "fine".

Is it worth that rebuild gamble?

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
