On a more advanced engine e.g Fully rebuilt , cams/head work and tune the lagg can be taken care of through playing with cam timing , while still not loosing any of the mid range top end punch these puppies deliver.Just take it to a tuner who knows the fine tuning insides and outs of the RB26 and you will be very rewarded.Should be able to see full boost 22 -24 psi at 4500 rpm or just under but they will start pulling hard much lower than this so are still a very streetable turbo set up.

Alot of the gtr forums I visit from around the world rate these huffers above 2530s for there response and big delivery of power in the top end.

On a fairly stock engine Id put a gtss or the 2860R -7 turbo upgrade ahead of these unless of course you are taking it further down the track,these are purfect for a hard tuned street machine.

On a fully worked engine these turbs are good for 380 - 410 awkws

Just my opinion though. :(

Exactly my thoughts there, ive got a full engine rebuild in mind for the near future and im hoping to achieve just what u mentioned. :P

Have a compare & contrast between the compressor maps for the -5 & the -7. Given the small difference in size & the marked difference in efficiencies why would you choose the -7? Admittedly at 30#'s airflow on the -5's you will be looking at a 600+hp engine, but this isn't off the planet surely?

      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.
