ok, i searched but can not find, so if i missed what i'm after point me in the right direction.

I have got myself a GTR R32 RB26DETT motor from JAPA land. Standard engine.

Apart from street use, i compete in Drift comps here in NZ, this motor has just been put in me car and soon to start it up and run it. I drive a Cefiro A31

Reliability is more important than max HP to me, so boost will be keept below 12psi.

my Questions are:

I have been told about worries of oil problems with the R32GTR engines. are they big enough that i should not be thinking about track use until I do some modifications? or are these engines just as reliable as any other RB engine.

I have limited time before the next competition (2nd October) and could probably remove engine strip clutch etc and take sump of and do modifications, but is this necessary. sure its a good idea, but is it a high risk?

Sump baffles should be easy to custom, any ideas?, but there is a common problem with the standard oil pump drive setup. How do I fix this. Please point me in the direction i need to go.

Basically, am I good to go (as good as any other engine??) or should I flag the competition and do some work on the engine to make it reliable.

I am running a standard engine, and will run 10psi-12psi boost. 3 inch exhaust, intake.

the engine has supposedly done 70,000k

My previous engine was a rb20det, done 170,000, i boosted it to 14psi and bet the shit out of it and it still goes mint till the day i removed it.

Thankyou for you input.

Hey,

I got 4th, i spun pushing my car a bit too much, pressure when up against the best. but will learn alot from the experience, next time!

Very happy to get up there considering i got to get used to my cars new setup, thr rb26 goes very well i must say even on standard boost settings.

Thinking about upgrading the oil system, dry sump. money money money!

oh, and the miss?? i'm pressuming your talking about my car not running right due to the fact I had not finished the return piping for the blow off valves. Friday morning i finished the pipe work and it ran great.

Other wise your talking about a little miss which is likely the plugs, or something. The car has not been driven enough for me to look into it. Currently modifiying guards for clearance and hopefully have a cert soon for road use.

AFAIC any car fitted with a stock sump should at least have some sort of baffle system fitted if it's to be used for trackwork. Stock sumps aren't designed for it and oil starvation/surge is a very real possibility. Obviously a dry sump system is the 'ideal' and probably mandatory for 'professional' competition, but it depends on how deep your pockets are.....

      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.
