finally got the chance to dyno my car in its current state. Using the hiflow which a have copped alot of flack about with using it, need bigger turbo etc but to me it was good. Got stock computer and injectors so mainly was to check a/f ratio's but made 346.1hp(258kw) at the wheels on 15psi. got power fc ready to go in but just need injectors now coz stock ones are at the peak. Rebuilt motor(rb26 crank n rods) ross forged pistons, head work,1.6mm head gasket, reprofiled cams, front mount cooler, bosch 040

And what was it before the hi-flow?

even with higher fuel pressure its highly questionable that stock injectors can cope with that sort of power figures. With adj reg, microtech ecu an high volume fuel pump, my stock injectors could only just stretch 230kw....before i tossed em for bigger items

the stock injectors could do it, it just wont be safe (or smart)

and with a walbro behind it

its a time bomb

lol...yeah I laugh every time someone tells me they have a walbro. Wow 255L per hour....that's good if you never come off idle. Add some realistic pressure and the pump only flows a maximum of 170L/hr.

I still don't think the stock injectors are capable of any more than 230rwkw but then again people told me 210 on my rb20 ones was bullshit....so I guess I have to keep an open mind. Still would have to see it to believe it.

i put my gcg highflow turbo into my car today it is awesome so much pull than stock turbo and so loud >_<

do you reckon i can 330 out of it with stock injectors but got the following mods, pfc, fmic, tbe, ebc, z32 , fuel pump, fuel reg...

cheers

Add some cams or you are dreaming

My stock inj are maxing out now at approx 190 -200 rwkw and i have an b0shch040. R u sure you made 259 rwkw on stock injectors and without timeing and a/f management...

Wont your motor detonate if you were to give it a bit on a hot day with those stats????? It would be running pretty lean!!!!!!

( i must have got a shite set of stock inj!!!!!!!!! or you are missing somehting!!!!!)

Good power figure for a highflow though!!!!!!! (if it is real) --> have you got a dyno sheet?

    • 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.
