Car does daily duties on this set up > http://www.skylinesaustralia.com/forums/topic/55845-rb25-turbo-upgrade-all-dyno-results/page-42

And the above for a drag day.

Notice the backend was changed and also no WMI is used alongside the C16 as it kills the power. Afrs are around 12.0 so injs have a little room still.....and so does the turb :yes:

Havent sorted the suspension for it to hook and put down an Et yet tho.....

my turbo has no antisurge and stock airbox...there is no whistle

actually apart from exhaust noise there is nothing

poor Bast#rd!! the whistle is awesome, get the cover and fill the streets with some RB 3076 whistle!! Edited by AngryRB

GTX wheels have quietness as one of their design targets - they are intended for industrial etc use, one of the reasons why some of the more high performance targetting (ie, EFR, HTA) potentially will have the edge in other ways over them, as response/wide & tall compressor maps etc are the intentions.

I'd take a closer look at a "GT3076R" with a T04S compressor housing on it , just to make sure that it has the GT37 compressor wheel in it .

I'd want the HTA wheel if I was running that housing or something that performed similar to it .

Does anyone know if Tao at Hypergear is doing cold side upgrades to GT30 turbos ? I'll ask this in their thread too .

I don't think you know what unopened means bro

I know what unopened means 'Bro'....... hahaha i read the title and my head automatically interpreted it as 'standard bottom end' lol

anyway whatever haha we all make mistakes :P

Still good power out of a gtrs. Lag must be non existent almost

relax man just having a stab. Those results seem pretty good for a gtrs on 20psi with a whole heap of boost leaks to the point where it feels laggy. I wonder how much the cams helped that figure. Also do you have vct? Might be a factor in the laginess you're experiencing

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
