I need to pass an inspection with an R32 + RB25 with an aftermarket fuel rail with GTR injectors in it run by a Wolf3D. Now I was just planning on swapping the ecu over just as I drive in as it is plug and play, will the car still run just really rich ?

If i understood right - You wanna run a different impedance injector than the factory ECU expect?

Won't work due to this

What about if I put resistors on them to match the impedance?

Worst case I can just borrow the fuel rail from a mates rb25.

Gtr Injectors + Rb25 + Stock Ecu = No Go

RB25det injector = 370cc

GTR injectors = 444cc

therefore even with the resistor in place you will need to tune they are change.

EDIT!!

If you were going to put the resistor in and use CA18det injectors then that would work depending on the latency, but there is no point as they are the same size as the RB25det injectors (hence why they work)

Go borrow or buy a RB25DET fuel rail with stock injectors, scour the sales forum, people get rid of them for cheap.

They don't look that hard to remove/fit so I might even just borrow my mates one for a day or two.

      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

      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

      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.
