I'll write up a how-to thread for sure, there just isn't enough info for these on a 34. Hopefully it's easier than it seems, but it'll be fun no doubt

There's 12 posts in this thread, half of them talking about whether the stock fuel system will work. If you're not gonna read those 12 posts, can you at least wait until I post the how-to thread so yo

Right, so after a few back and forth emails with the Plazmaman sales team, I'm highly doubting they are going to be any help to me. I asked (before Dahtone replied here) whether the stock top feed fue

had to remove my washer bottle filler neck as my battery had to be fully pushed against the chassis.

so gonna have to connect a clear hose and run it from the washer bottle into the engine bay. dodgey but it'll work :miner:

I'll just ditch the stock washer bottle and buy a small universal one. Either relocate it to somewhere else in the engine bay if it fits, otherwise to the boot. Stock one is ugly anyway :P

A lot of people put the battery in the boot (for cars that don't already have it there) and get a fabricator to make a combined washer bottle/catch can to fit in the available space (some with cut outs for the intercooler piping). I am too cheap for that and I have found that my washer bottle can share the space with the piping by making some new brackets. I may have to go with the flexible filer hose as above^^^ but am not prepared to lose either front or rear washers they are good for an extra 10kw at least!

IAC valves can easily be replaced by a competent tuner. My Plazmaman plenum allowed me to run the stock RB25 IAC (upside down / had to extend two wires) but I ended up pissing it off and replacing it with a piece of flat steel, some silicon and the bolts that normally hold the IAC in place.

Not really, pwr steer idle up, a/c idle up, auto anti stall etc are all required for the niceties of a daily driver.... many afm based ecu's strugle without one. Nistune for one is happy to make upwards of 500rwkw but does not like having the iac removed.

if your ecu allows it and your not fussed about having a higher idle than std etc than yes it can be tuned around (mostly map based ecus).

The only people who seem to get good results with these are guys who need to justify the fact they sold it to the customer.... yes we tuned heaps yes they work (like std) would i put one on my own car ... no.

i wanted to run mine without IAC but my tuner advised against it for the above reasons for a/c, power steering etc as it is recommended to run it.

if i could, i would remove it and tune without it as it makes my engine bay look so messy.

Plenty of space in the boot for a washer bottle! - (no I'm not joking, that's where mine is).

Worth popping your boot to fill it up when you have this happy.gif

screw that.... that whole car is super sexy.

Thanks! Looks totally different since this pic - alot has changed. Sadly it was the only shot I had that showed my plenum so I had to use it.

The plazmaman makes you actually look forward to changing plugs, instead of putting it off because of the annoying cross pipe set up :D

You mean the loss in torque? That's got nothing to do with the motor, it's the length of the runners on the intake. As a general rule, shorter runners = less mid-range more high end, longer runners = more mid-range less up top.

Niceties of a daily driver? Lol. Sometimes I forget that my priorities don't extend to giving a shit about those things. Still the car functions perfectly well, doesn't stall, steers fine and doesn't have air-con. ;)

Bugger that, for a daily i want aircon :thumbsup: All i gotta do is figure out an A/C fan to replace the stock one as the Plazmaman intercooler is so much thicker than my old ARC :cool:

Quick question for those with FFPs and stock bovs, where are you relocating your bov to and how did you do it? I'm currently thinking about what I'm going to do with my stock GTR bov. Ideally I'd like to keep it, but if it's too much hassle/cost then I am considering just ditching it. As I understand it, the closer to the TB the better, yes? What about flanges, where can I get a weld on flange?

My fabricator put the bov near the ffp and it vents to atmosphere ( I have a G4 Link with a MAP sensor). I hate the sound. I plan to relocate it to the other side (hot side) of the intercooler so I can plumb it in. I will need a long vacuum line so may make up a hard line.

No nearer the T/B is not better. Garrett actually say as close as possible to the turbo. I am sure there will be a fluid dynamic engineer or suchlike who can correct me but my take is that bovs are not about flow but about pressure relief and so it doesn't matter where it is. Some manufacturers put them on the intercooler itself.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
