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 .

Standard re built S1 rb25, pon cams, ex cam gear +8, walbro 460 highflow standard side feeds 740cc, power Fc, hks gtrs kit, blitz fmic, gtr itbs etc etc

United E85

Royal Purple 10w40

Street driven soon to be tracked

303wkw @ 20psi

Massive boost leaks and 4psi back pressure at 20psi at O2 sensor port and clutch issues... All to be sorted next weeks and a retune with new eboost2 controller

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

Nah man its a little lagy hey....... as i said earlier, tons of boost leaks and some other issues haha soon to be all fixed :D

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

    • If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.
    • This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).
    • I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.
    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
