Hey guys i just bought a r34 sedan auto, i'm buying new rims this week and getting it lowered, getting a full exhaust upgrade, just wondering for those who live in melbourne where is a good place to get a dyno tune and how much am i looking at cash wise which is still no problem just curious on the approx gain i will be expecting?

To be blunt, it's not worth doing all that many performance mods to an auto N/A skyline. You'll never get value for money.

Are you going an aftermarket ECU? A nistune board (which you can't have put in an R34 Rb25 ECU) would cost the best part of $1000 to have installed and tuned and I'd be very suprised to see more than an 8-10kw increase, if that.

yeah i heard everyone say the same thing that there is no point upgrading performance on a n/a skyline but in the end of the day it will be turbo one day since i am 22 and i would just like to slowly enhance its performance for when i get to the turbo stage. Money wise also isn't a big hassle since i do work and have saved to spend money on this car without breaking a sweat.

It's not about money being an issue, it's just about being smart about your money. By the time you've finished upgrading everything, you could have purchased a GT-T manual coupe that will be faster for cheaper.

There's not much point in spending all this money on your N/A if you want to turbo it in the future.

The best choice (money wise) is to keep the N/A stock, save more money and then when you want to then upgrade to a modified GT-T.

I have a r34 gts manual coupe. And I really don't want to have to find a complete new whole car since graduating to my full licence, so being that I'm still very interested in a turbo.

Is my best bet buy and rb25dett and slotting that in place of my neo 6 rb25de.

Or buy a more costly better aftermarket turbo manifold accesories ect ? And bolting on and tuning ?

Not really sure about the r34, but in the case of the r33, the turbo version comes with bigger brakes, stronger gearbox, 5 stud hubs, lsd. So while people might want to keep the car they know, the cost of turboing a natro properly will cost roughly the same as buying a whole turbo vehicle.

Thank's guy's i won't work on the performance of my car just replaced the rim's and got it lowered looking to put in a new full exhaust system in the near future and i will just replace all the stock speaker's and not get sub's but yeah when i am full licensed i'll just import a gtr. Overall i am happy with the way my skyline handle's corner's at 90km without sliding out. Everyone gave me grief before buying this car saying it will be crap because you will have to pay to much for insurance ect ect,I barely payed over $500 for insurance, rwc and car transfer. I am happy i stuck with what i love which is a nissan import and not a ford or commodore.

not just that the compressions in the NA and turbo engines are different, you cant just add a turbo to a NA engine with a tune and expect it to perform the same its always going to be sluggish and it would have been better off staying NA.

im in the same position as you, restricted license and i have a NA R34 GT-4, im more then happy with the car in every way for now and was considering a RB26 upgrade when i get off a restricted license because ive spent over 10k extra on my car already and am fairly attached to it but its just not worth it, in the end ill have to sell to get a turbo but knowing a GTR will follow wont make it to hard ;)

You will actually find that a natro with a turbo booked on will put out more power and be more responsive than a factory turbo at the same boost level because the natro runs higher compression. The issue us that a natro with a turbo will be more probe to pinging/detonation so you are restricted by how much boost you can run before it starts to ping, which will be lower than what you can run on a factory turbo engine.

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
