considering no one mentioned anything when i asked for advice a month before i purchased them, then as soon as i did purchase them you both seem to be more off my choice and want to rant about it then help. they were $300, i couldn't care less and will live with my decision haha.

Um, ok. You asked and the answer you were given was it was unlikely to be the Nissan bov's which you went and bought replacements for anyway. So now you get steamed when the same advice is reiterated? Why did you ask in the first place if your mind was made up?

Also:

Sorry for pointing out an atmo vented bov will upset the ecu.

Sorry for providing the link showing the limit for the stock afm's and their obvious replacement with a Nismo item which will bolt up to your arc airbox.

Anyway enjoy spending yet more money fitting stuff that will make no difference.

Lastly you need a mechanic who knows GT-R's not that youll listen to that either.

so ended up listening to you guys and have got everything sorted now, thanks for the help.

main problem was my old boost controller was failing and was set at 18 psi no matter what so thats what would have blown my stock turbos in the end,

after taking it to get those parts installed found out that the afms were dud so had to stick with the stock ones and dropped the blow offs and am still using stock but did the fuel reg, rail and injectors with the tune to suit the -7 turbos and hollowed out the cat to give the exhaust some better flow.

ended up with 280 hp on 0.8 bar boost and 350 hp on 1.2 bar boost with a pretty safe tune that im happy with, and now just using a duel stage turbosmart boost controller

for the moment im happy with the power as its reliable and gets on full boost pretty quick, later ill do the Z32 AFMS and a better fuel pump set up to get over the 450 mark

just my personal opinion, but i would start hiding all the controllers, torque switches, timers, hand controllers ect and get some damn carpet mats :P

but, whats the missle switch for?

Edited by GH05T

missile switch is for boost settings 0.8 bar or 1.2 bar, got pulled over yesterday and the cop just needed a powered trip, got me for not wearing my glasses $250 and said my cars not regod because i live in NSW with a NSW license but have qld plates and rego because i have it "garaged" in qld, he gave me a warning and said if i do it again $650 on the spot fine, called the RTA in the morning sorted it and now its all legit and a nsw defect will be usless and wont carry over to qld so basically i cant get stung in NSW for any of the mods ect since its all legit in qld. plus where i live highway patrols only come to town like once a month, this is the first time ive been pulled over in about 3 years of driving slammed imports so i dont really want to hide all the switches ect, carpet mats are to come in future!! but i need to finish off my chrysler 300c now that the GTR is running mint

For some unknown reason my current tune is acting up and running lean, splutters on boost and engine light is on so ill have to take the car back for another dyno session which is a bit annoying but gives me a good enough excuess to go Z32 AFMs and get a propper fuel set up to get close to 500HP

anyone got any info on what a good fuel pump set up is to run on GTRs aiming for 500HP+, was thinking on keeping the walbro 255 intake pump with a added surgetank and bosch 044 in the boot, mise well get it right the first time just not too sure what is best.

what computer are you running or going to run?

if your going z32s im assuming nistune?

any thoughts about going to something like haltech?

once you buy the new afms and the unit your not far off a computer that will give you allot more.
especially if your going for bigger numbers.

Edited by GH05T

havent really thought about changing ECUs mainly because im not too familar with them, only just getting to know the apexi power fc now

how much can you generally pick up a haltech ecu for and they will mean i can run a mafless tune hey?

id be spending close to 600 on just the afms anyway and if i ran a tune with no afms theres another 1-200 i could get off the stock afms which would be close to to the price of a new unit im guessing (just having a ook now)

and are there any other benifits a haltech would have over the apexi power FC?

yeah, usually between $2000 - $2500 depending on how well you know people.

yeah their mafless and they will give you better management for knock and you know, if things go wrong. better protection, better tuning caperbilities.

and yeah sell the PFC sell the afms, dont buy new afms and go for more power.

yeah 2k of just jap

mise well do it could get 800 back for the apxi fc the 600 i didnt spend on new afms and sell the old ones will pretty much give me the 2k

ill start getting onto it asap,

have you got any ideas on a good fuel set up to run?

    • Good luck on the weekend mate
    • 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
    • Welcome to SAU, what are you looking at buying?
    • 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
