Hey all, Yes, I've searched and found this: http://www.skylinesaustralia.com/forums/in...18&hl=BCK*&st=0 and this http://www.skylinesaustralia.com/forums/in...=8&t=92133&st=0 But I'm not sure if I've done it right. I'm ok with the plumbing side, but it's the wiring I'm not sure of. Included below is a dodgy diagram of how it's wired up now. Also some excerpts from the BCK manual that came with the kit (in Japanese) and an old manual for the AVCR from the US Apexi site. Car: R34 GT-T (RB25DET NEO) BCK model no.: 415-A013 Both the PFC and BCK are only a month or two old. Again I had the problem of having nowhere for the two-pin spade-type connector coming from the solenoid to go. Has this been done this right? Or totally wrong? The car is running ok but doesn't seem to be holding consistent boost (set to 1.0kg/cm2, duty cycle 64). Please help. Thanks.

used greenline.jp for some small parts (injectors, PFC-BCK, interior bits). took less than 1 week in one case, around 10 days in the other cases. i say go greenline....

stocko SR20 pulsar. preferably in beige. enough power to not be totally annoying but safe FWD handling to not get you into too much trouble. some have ABS and an airbag too. that said the biggest accident i've had was in a 1.6L laser at about 50km/h - got driven into (was not at fault, insurance sent me cheque, woohoo!!!) and in about 0.5 sec i was sitting in a wreck with the dash wedged against the gear lever and a lump on the head. it all comes down to attitude, being alert, aware of the potential consequences of the decisions you're making and basically being paranoid that everyone else on the road is a complete moron who is out to kill you.

PS What kind of wheels do I have? Rays.... somethings.....

GMR at Woolloongabba. Speak to John. He stays open late (8-10pm). 3392 0777. Tell him the guy with the black R34 sent you.

hey bob, nice result! be good to see how it goes once you've got the final tune in there. i'm with paul - PICS PICS PICS!!!!!!! (boost kit and Z32 AFM for me next week.... )

got the issue of HPI today (freaky timing, having that article in it), looks like chris might be the go. i won't start the debate here about black wheels vs silver wheels on a black car... thanks guys.

thanks! any other good wheels places guys (southside maybe?)....

not really on topic but just thought i should mention it, saw a nasty-ass old beat-up white VR commodore the other day with an STi sticker on it. commodore STi. i actually laughed out loud. :lol: got a wave from a white S2 R33 the other day too, first person to actually wave back at me.

Hi all, The coating on my wheels has been bubbling and flaking off in places since I've had the car. It's kinda annoying me so I was wondering if anyone has advice: 1. Ignore and don't worry 2. Get them sand-blasted and powder-coated 3. Other options? Wheel repair/reconditioning places??? Option 2 is probably sensible but - wank factor aside - I'd like to retain the Nismo logos if I can... If anyone knows of somewhere reliable in Brisbane to get this done, the advice would be appreciated, thanks! Pics attached.

Iridiums gapped to 0.8mm as far as I know. Won't be able to confirm until my mechanic re-opens in the New Year though.

Head Unit: Sony CDX-R3300S CD/MP3 "control blade" tuner, 52Wx4, $180, rating 4/5 Front speakers: Pioneer 6" 3-ways, blue, $90, 4/5 Rear speakers: Pioneer 6" 2-ways, blue, $60, 2/5 Sub/s: Kicker 10" in sealed box, $140, rating 3/5 Amp/s: Kicker K150.4 driving fronts and sub, ?$200, 4/5 Overall: Good cheap bang-for your-buck system, wanted decent clarity and tight bass response on a budget, without sharing my music with everyone in a 10km radius. The rears are pretty average but still better than the OEM crap you get on most 90's Jap cars. The only thing I would change are getting split fronts and putting the 3-ways in the rear. Oh and the ergonomics of the Sony head unit are awful, I like dials that you turn not crappy rocker switches, and the gaps in between MP3 tracks annoy me. But for $180 new I wasn't going to argue! It gets too loud at the point at which you're pushing too much distortion through the speakers so I can't complain about the volume levels. Can't justify spending $1K on a "system" when that'll buy so much other fun engine stuff...

My feelings are pretty similar to Bass Junky's. I feel it's about 90% of the way there in terms of the tune but basically it's a versatile car to drive. Keep things below 3000rpm and drive like a Sane Person and it's a relaxing car, with good throttle response and reserves of low-speed torque. Kick it up the arse and yes, there is a "stepped" power delivery at about 3500rpm when it spools but it's not wild and doesn't produce clouds of smoke in anything other than 1st gear. During the process of doing these mods the point at which it lost a little throttle response was fitting the FMIC. That was one thing I definitely noticed. Quick question - the misfire I mentioned above is still present but only at 4000 -5000 rpm and only on WOT in 2nd and 3rd. The AFM is definitely maxing out to approx 5000mV but is there any chance this is a coil problem? Visually they look fine (I've seen some stuffed ones off an R33) but I remain suspicious given the descriptions in the coils thread sound exactly like what my car does. The PFC is not logging big knock values but of course is logging that 5000mV ceiling on the AFM. I hope it's the AFM... it didn't misfire on the dyno at all, only on the road - maybe because you're sucking more air on the road cos the fan unit they use at the dyno doesn't give you a similar volume of air? What do you reckon guys? Or is it odds on I'll be stumping up for Splitfires soon? Hope y'all had a good xmas. Cheers!

I haven't felt any power loss at low revs or on low throttle openings. And during on-off throttle driving it spools quickly, you're not left waiting for 2-3 seconds for the power to come back on. The main thing is if you're going for it then keep the revs above 3000.... but it's not annoying or laggy to drive in "normal" situations at all.

Speaking to Paul this arve the spike itself didn't cause problems, it's the adjustment of the actual little Turbotech valve that was problematic - half a turn takes you from 10PSI to 17PSI... Initially we ran into problems, kinda like a random misfire/stutter between 4000-5000 rpm. Apparently my coils are ok and it has a new set of plugs so the likely thing is maxing out the AFM. If it persists I'll go for the Spitfires anyway, but first I think the Z32 AFM and boost control kit should go in and see how it runs then. The torque curve was very broad and flat too. Didn't get a printout (dynos are not the best at measuring this apparently?). Yeah after the turbo spools if just feels linear, power builds progressively. Things can get a bit out of hand in 1st gear but I mostly hold traction in 2nd - the sticky tyres help!!! So I'm happy with the result, but not 100% happy overall yet!

Ok so had some tuning done today. There are still some issues with the car in its current state: - AFM maxing out to 5.0V (Z32 AFM on the way) - boost spike from Turbotech BC (PowerFC boost control kit on the way) But otherwise here's the spec: No-name-brand pod filter MTQ GT2876R hybrid Blitz LM FMIC Bosimporting split 3" dump Catco 3" metal cat Blitz 3" Nur Spec cat-back Apexi PFC Turbotech BC Bosch 040 Nismo 480cc injectors Result was 226.5 rwkW. The tuner thinks there's a bit more in it but we need better boost control and better AFM resolution to get there.... which is kinda what I *thought* might happen. As for what it's like to drive, well... it's FUN, especially that lovely spot at 3500rpm where everything starts to happen. From that point on it's linear and IMO spools quickly. It's got HEAPS more midrange than before which is what I was after. Just gotta wait for the bits to arrive so I can get this 100% where I'd like it.... Comments etc welcome!

sold.

bump

saw about 4-5 silvias/200sx/180sx driving line astern across the captain cook bridge in the middle lane tonight. i few had NS.COM stickers on em... looked to be behaving themselves. the only plate i remember was CYA something...

still for sale.

I'll be able to give you a definitive answer next week - PowerFC arrived today and have booked the tuner+dyno for Monday. :lol: Will post any graphs I can lay my hands on! At the moment it's beginning to spool at 3200rpm and really gives you a fair shove in the back at 3500rpm... Boost gauge reads 11PSI. Then at about 4500rpm (especially in 1st and 2nd gears) the ECU spoils the party. So once I get this sorted properly with the PFC and the injectors that're sitting on my coffee table at the moment I'll post and try to describe how it goes as best I can.

hey paul, received PFC today, not as long a delay as anticipated! install + tune next week. thanks...

well i think it's pretty good. coming on strong by 3500rpm. hard to subjectively say though not having felt the characteristics of anyone else's. to me it's not that much laggier than the std turbo. so frustrating cos just as it starts to boogie you can feel the ecu freaking out and pulling the spark out...

maybe electrical connection rather than anything to do with your fuel level?

hey guys, i'd like to chip in - i'm an R34'er in the midst of doing very similar things to abo bob and bass junky (by the looks). anyway i've already posted here http://www.skylinesaustralia.com/forums/in...8&t=93572&st=20 but thought you guys might be interested in my pre-mods power run recently. it made 198.5 rwkw. spec: pod full 3" exhaust (BATMBL split dump/front/cat and Blitz cat-back) gt2876r-core hybrid turbo from MTQ turbotech bc running ~11PSI absolutely everything else = stock it's obviously running pretty rich and i guess bumping into the R&R from the stock ecu? anyway should be interesting once everything's done. waiting for the powerFC to arrive next week then the fun begins. final spec will be: pod full 3" exhaust gt2876r hybrid 14-16 PSI powerFC blitz LM FMIC bosch 040 pump nismo 480cc injectors Z32 afm if needed who knows what power. a result like bass junky's would be awesome. a nice chunky torque curve and a decent time at willowbank is what i'm after. cheers!
