People,

GTR Cam on here is having some wiring issues and is after the wiring diagram and possibly the entire Workshop manual for a R33 GTR.

Now he has the one for the R33 GTR however the wiring loom as on his car is VERY different, unsure whether this relates to it being a V-Spec, however word is that this is the reason and there is a separate manual.

Any help would be greatly appreciated as we would all like to see this car back on the road ASAP.

If you have anything that could help please email me at

Or GTR Cam

Thanks

Neill

Oh god...not more zip ties

Nah mate.....

Stock ECU uses a twin fuel pump set up, ie high & low, whereas the Motec uses low only (std setup)... This appears to be why it's missing at the top (on the street under heavy load) as a result of the car squatting, there's not enough fuel being drunk.... hehe. This would explain why the missing at the top of the rev range isn't happening on the dyno (ie it's not squatting)...

So the guys are using a connector plug to mimic the stock ECU setup so as to ensure enough fuel is delivered...

Keep ya posted!

sounds rather odd as with new wiring+relay setup, fuel pump should receive 13+ volts constantly so it'll pump as much as it can all the time (wears out the factory pump but too bad :P , upgrade to bigger one ) :confused:

Agree with the Jap man on this one...the pump operates on a continous feed basis with unused fuel returning to the tank. And the fact is your using a Malpassi to reg fuel pressure so this should not alter becuase of the ECU...

*Looks at Walbro fuel pump on net*

Seems you will have to keep me updated!!!

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

      R32 GTS (RB20DE) Injectors Replacement

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
