Chassis: USDM 1998 240sx (kouki)

Engine set: ER34 Rb25det (Neo)

Mods: Cometic headgasket, Arp headstuds, Isis Intake manifold (r33 IACV not wired in) Aftermarket no name fuel rail, Aeromotive 13109 FPR, FMIC, Q45 Throttlebody

Pros: Starts with Brake kleen/ether, will idle, run an boost 12psi with no problems after started.

Things ive checked, CAS, injector and pulse also drivers (on ecu "battery voltage), Have Spark on all 6, fuel pressue (43 an holds ign on), Compression, IGN signal +, Timing

Plugs an gap..

Problem

Dont matter if it is hot or cold i have to spray it with ether to get it to start. Unplugging the TPS or MAF does not help, this problem appear to happen after going to the Aeromotive FPR as with the stock rail i modified to work it started every time. im using topfeed injectors double 11mm for upper an oem neo lowers oring on brand new r33 cushions (sidefeed) found 3 of the cushion to o ring leaking (spray with brake kleen an need a misfire) thats not the reason it no starts though.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      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 is has not responded to my emails so far after 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.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋
