The GTX3584RS will support roughly 850-880HP on a 3.0L (maximum rpm of ~7500-8000) at a PR of about 3.1-3.3 No chance of getting 1000HP out of it, not unless it can be done at a PR of 2.75 and even th

Lets put it a more logical way - why do you want to go with the Avo .73a/r housing when there is a housing option which is proven to get the most out of the GT3076R which comes with the turbo? For all I can tell you want to do it just because, because there is no logical reason I can think of. The turbo comes with the Garrett housing, its easy to get a dump pipe made up for it, and most importantly you KNOW its going to work.

Not saying the Avo housing won't - but why take the more difficult and expensive option when there is a known quantity? It doesn't make sense to me.

Thank you for you putting it in a more logical way and not just speaking fir the hell of it.

I was aiming at .73 in an attempt to get a balance between the more responsive .63 and higher flowing .82. Also keep my dump pipe.

If you were thinking of a GT3076 and wanted something in between .06 and 0.8 for a mix of response and power, would a 3071 in a 0.8 housing fit the bill? Pretty sure there were dyno results recently posted that had 270kw and really good response?

Is this the Gtx series ur referring to? Cos yeh I know that's another option. May be leading that way....

OK. For what its worth, I feel the difference (having had both) between a .63 and .82 is minimal - I run a .82 and don't feel robbed of down low, it has a very nice power delivery. If you are really that worried about a bit of a mix, just get an HKS GT3037 with .68 housing.

You can't directly compare a 0.73 non-native housing to a garrett housing. It is based on a ratio and it won't be same when you compare housings.

Yeah look I think I'm leaning towards. Gtx3071 with .82. I appreciate your advice regarding 63 and 82.

Sounds like a defect/EPA waiting to happen mate, really hope you don't get pulled over...

You should make 300rwkw on PULP though either way. 260 is rather conservative and a normal GT3071 will do that.

Awesome - looking forward to seeing how that goes, it is definitely what I was sold on until I saw the first results of the GTX mid frame turbos. Good luck, could be interesting :)

I finally just took delivery of my new GTX3071R!!! Here are some pics up against what it is replacing.

If the GTX wheels work like their maps show then mated to a 0.82 turbine housing should be the right combo for and RB25.

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
