.84 split pulse

.81 single pulse

id go .84

0.81 suits the 26 perfectly so will be abit small on a 3L i reckon....

Hey StageZilla,

What is wrong with the .84 split pulse? Why is the .81 far better?

Just really interested as there have been a few threads about these turbo's in respect to response. R31Nismoid said these turbo's may be able to make the 500rwkw mark; what exhaust housing would you use for this application? And will it loose its 2530 type response?

although i dont remember outwardly saying 500rwkw anywhere  :)

Yea, you did. Quote below.

With fuel and boost 700rwhp i think it would get close too with more boost. I dont think pulp will achieve it... but you never know

It was the post about the TO4Z results.

I used the "SEARCH" button. You must be proud of me! :P

i was only going by the hks t04z's sorry, they only do the 3 housings, 0.64, 0.81, and 1.0 i think, and as r31nismoid said it depends on ya manifold and whether it is split pulse.

cheers

Just to tack on to the end of this thread, does anyone have any experience with the Garrett T04Z with the 0.96 exhaust? I assume power would be very similar to wrxkilla's T04R dyno graph from a few weeks back, and same sort of lag/response?

Talking about a 2.6L too, not a 3L :)

    • 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.
