Racing around the track with a full tank no worries. Got down to about a half a tank and when hitting hairpin corners hard motor splutters for a moment and picks up again. Acceleration in a straight line no worries. Mods include standard peripherals including fuel cut defender. Tried turning boost right down still surged.

If it only happens when you are taking hairpins on half a tank, then by fuel surge, you mean it all sloshes to one side of the tank when you take hard corners?

and it still does it at low boost, which should eliminate the fuel cut defender as the problem...

does sound strange. is it possible for the pump pickup to become exposed to air if you dont have a surge tank? (ive never seen inside a tank) Coz thats what it sounds like, only happening when you corner...

Ive just had fitted an 044 myself, but have yet to take it for some punishing corner work. But with my old pump, i used to rip around the hills on empty and never had any probs :)

hope you get it sorted, any big tuning house should be able to tell you why its doing it.

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
