Here are my plans:

- 3.5" Downpipe to a 3" Test Pipe and a 3" Blitz NUR Spec R Exhaust.

- Greddy Profec B Boost Controller

- HKS Turbo Timer

- Boost/EGT/(Air/Fuel) Gauges

- Twin Electric T-Fal Fans

- Skyline R33 GTs-T Radiator

- Apex S-AFC

- Blitz FMIC w/ custom piping

- Homemaid K&N-Filtered Cold-Air Induction

- 12 psi Boost

Take a look at those plans and lemme know what you guys think... suggestions are very welcome, especially ones that make things a tad cheaper!

Now a few questions:

1.) How much power does the stock GTs-T clutch hold?

2.) How much power do you think I will make out of this system?

3.) Think it will be reliable?

If you are going to go a 3.5" dump pipe you should go 3.5" the whole way, other wise the bigger dump won't make much difference.

The stock clutches aren't that crash hot. Mine really started to slip when it hit about the 180rwkw mark, when I was giving it a hard time.

Exhaust: ditch the name brand muffler and buy something local thats of straight through design.

Boost controller: a decent bleed setup will hold 12psi ok. Mine does.

Turbo timer: use yourself. ie hang around for a couple of minutes after a hard kane :cool:

Radiator fan: standard clutch fan won't fit in engine bay?

Can't comment on power output, what with the different dynos you guys use and everythng. Will be very quick in a s14 tho.

Well, I said decent bleed setup - turbosmart is not this. I'm using a Norgen pressure regulator setup in recirculating cycle, works fine. May not be perfect, but suits my needs. Remeber, Nismo_Freak is looking for ways to minimize costs and a bleed setup excels in the value for money stakes.

whats that pressure regulator off?

bleed valve is good for starter, but u cant beat a ebc for tuneability later on

      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

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      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.
