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 .

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

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
