Hi i was wondering what kind of traps and time i could expect to get in my Nissan Skyline R32 GT-R. Just finished it recently here in Iceland. Built motor , standalone etc.

Track is at sealevel and its usually not extremely warn here. Is it reasonable to expect to get it to trap 140 mph with my setup on high boost ?

Can you guys post some times and specs for those of you running GT2860-5 , GT2860-10(2871R) , HKS 2530 and 2540/GT-RS

Instead of posting a long part list - just post up power.

Pretty easy to work out a ball park from there.

cant really post the power, no dyno here that can handle over 500whp. So we all just road tune the cars.

i was also asking other people with the same turbos or similiar turbos to post up their times. To get an idea what people have been running with

GT2871R , HKS 2530 and 2540 , GT2860-5´s etc :)

It depends on how good your engine is, how heavy your car is, how much boost you are using, what fuel you are using etc etc.... I know of people running anywhere from 9s to 11s with those turbos. The standard response is, go and do it - what someone else has done bares little relevance to yourself.

In short, as fast as 9s are possible - odds are you won't hit them unless you have a car hell bent on going fast with good tyres fuel and are a well experienced driver.

Mate by and large - 99% of those mods mean sweet fk all.

The turbos will make "X" power on "X" fuel. Rods mean nothing, pistons mean nothing, coils mean nothing. Same for injectors, fuel pumps, AFMs etc. None of them are contributing factors to a ET. They are simply supporting mods for the turbos.

End of the day its the turbos that decide MPH, then traction for the ET

Go and run, get the MPH, and work from there.

of course they mean something, you need to have large enough injectors and enough fuel to make the power.

I cant go and run the car since im in Iceland and the track doesnt open until May. Thats why i was hoping someone with a similiar setup would chime in and post what they have run at what boost level and what kind of power it made

I used to have a Toyota Supra with a Precision billet 71mm that ran 10´s @ 140mph

I still say no.

Put 1000cc or 4000cc injectors - they car won't make anymore power.

So as i said they are simply supporting.

Without knowing what fuel, tyres, gearbox, diff ratios etc... We aren't going to get anywhere dude.

As said earlier - you could potentially run 9s. Or you could run 11s

No-one can answer it accurately.

Thats not what i ment, i ment if for example a car had a huge turbo and still had the stock injectors and stock fuel pump it wouldnt even be able to make more then roughly 400whp hence it wouldnt be able trap very much

But i was mainly after getting someone to post up some times that they had achived with the same turbos i have or even a bit smaller. Just to get an idea what people are running

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
