hey guys i finished the rebuild of my 26/30 setup and put the coolant in ready to start the motor and the bloody water pump (second hand rb26 one from another motor that was fine previously) is leaking from the hole underneath so the seal has gone. I grabbed the spare 26 pump i have and its also leaking so im lookin at a new pump now. Can i just use a rb30 vl water pump? im keeping the revlimit to the 7000rpm mark so its not gonna be revving its head off and im sure a generic vl one is gonna be easier and cheaper to get hold of. I have a spare vl one here as well but the impellar does look a fair different design to the rb26 one.

How many of you guys are running a rb30 water pump on the twin cam motors? and any issues?

anyone know what a new genuine rb26 pump is worth and a rb30 one?

Brad, I'm running an OEM RB20 water pump on my 30. Bought it brand new and because it was my daily I opted not to go for the N1 waterpump.. now that it's not a daily though.. hopefully it does alright.. new revlimit will be 7500rpm.

nah i got the gt3076r back on it and running 1 bar its great, got abit of boost creep at high rpm though which is annoying, gotta look into it and wind it up to 18psi or so ;) i reckon its making around the 340rwhp at the moment at a guess, feels slow compared to the old motor but has great response (1 bar at 2800rpm)

sounds like yours is just getting better and better, ive been there and done that and learnt with this one to stop spending and only buy the basics or it just ends up out of control :)

Nowhere near out of control, just decided to do it all properly instead of trying to hold it back because of certain components :) Had big dramas with the exhaust manifold which set me back a couple of months :thumbsup:

      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.

      I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
