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

    • Power steering is probably because someone has nuked the HICAS CU and you no longer have the variable power asist doing what it is supposed to. How much boost are you running? You are aware that any more than 10 psi on the stock ECU is just asking for it to go to full R&R (that's Rich & Retard, which is effectively Retarded and Retarded!) which kills all the power. Depending on the exact conditions, it can just be runnign on the fat and stupid end of the maps, then the conditions change, you make a little more boost and the ECU goes into panic.
    • @BuiltNotBought Just as GTSboy said.   If you want driveabilty and more low down torque..keep the stock runners. They are VERY good from a factory. I have them too on my RB25DET NEO and as a GTSboy i have fmic but with stock piping route(i have Blitz intercooler) Iam making around 320 BHP and the car pulls "hard" from like 2,5k all the way to 7k. I have it dyno tuned to mimic N/A power curve and making little less max torque due to the smallbox tranny. But driveability is very great. I had 350Nm below 3k so car feels very quick.
    • Looking to sort out a couple of issues on my skyline  It recently was rebuilt, however rebuilder long story short did not give two flying effs about the work he did. So moving forward it's running but I have two persistent issues 1) it has a misfire / lag type of issue (was at higher RPMs but I had a dead piggy back ecu removed which improved it) now it's not as bad but still does it at random, I thought it may have been a boost issue I'm running an older turbosmart dual stage controller, turbosmart told me to try running off gate pressure however it still has a lag at random times. It has New MAF, maf plug, coil packs, sparks, CP harness.. injectors tested and cleaned. Factory ECU. 2) Power steering issue. It is tight as anything. Flushed power steering, rebuilt my pump because the bearing was shot. Flushed again still tight (mainly when parking and going slow into my driveway etc)  No kinks in hard lines, replaced the lines I could see had cracks. Still tough to steer.  I was told to shim a coin and place into the solenoid plug? Is there anything else. My steering angle sensor also has a issue. It's a used one I replaced, does it need to be calibrated? I feel like I've tried everything and this car is my voodoo doll.   
    • Holy shit... wow!!! I totally missed this
    • One main filter. Each tank has a prefilter to keep rocks and small children out, then the big main filter that also does water separation. Clogged the first one so bad it was like a rev limiter at 3200rpm. Literally just like dropping the throttle off and maintaining rpm!
