it's a manual RB25DET equipped GTS-T, seems to have the 'super HICAS' on it, whatever that is :P ....and it has one of these little f**kers on it, which I've no idea what to do with..

how do I set it up properly, the boost on both settings seemed to be wound ALL the way down so it made all the funny turbo noises with no power produced :P

I don't know shit about turbos OR skylines really since I've never owned either. Educate me!! :D We smashed some new oil into it today, replaced driver's seat that had a rip in it, and gave it a quick backyard spec alignment (was way off, probably due to something i haven't worked out yet being bent..) and it seems to be going alright. Tried winding up the boost on the high setting a little; seemed to work somewhat but I'm worried about leaning it out because I know nothing about these things :) is the factory boost gauge usually fairly reliable/accurate?

Anything I should be looking at changing immediately on purchase? Was thinking plugs and leads but I fail there because it doesn't have leads :) lol..

Anyway interested to hear ideas on how I should approach this! I need to learn a lot about this car.

Thanks

Sam

the factory boost gauge is far from accurate, and you should also note that it doesn't read in PSI. first thing you should do before playing with the boost is get an aftermarket gauge.

as for how much boost you can run, that depends on your mods, but if it's still running the stock ecu then if you go too high the ecu will start to work against you. you shouldn't have any issues with it leaning out (unless the fuel pump is shagged) but the opposite. the stock ecu will make it run rather rich.

got RWC today.

turbo timer is on the to-do list, along with figuring out why it doesn't like WOT..

any recommendations on brand for the timer?

Coilpacks are Splitfire, look brand new, and I replaced the plugs with NGK BCPR6ES as recommended by an antilag member.

Boost gauge definitely on the hit list, need ideas on where to mount a few gauges as well as types that don't look too homo....

      George's R33 GTST build

      By pogman · Posted

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.

      Mistakes were made, my R34 Story

      I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛

      Nah, not really responsible for that little fiasco, but I'm still pissed at myself for writing off my 86, or when I reversed my VX into a pole just before selling it, but, meh, 5hit happens to stuff, all it takes is a slight distraction, and life is full of distractions, and "dooh" moments

      Ah yes but were you responsible? In the time I've had it (just before Christmas) I spun off the track twice and drove into things twice, so four separate incidents.. in two outings. Luckily I have a full OEM GTR front end to put on which is hopefully not a precursor for further, future, more expensive mistakes to come. It is some consolation that anyone who would want to buy my Altia bar would have to paint it anyway, the guards, too. (if they can get over the asymmetry). Hopefully over the weekend I will disassemble and see how badly things are bent. From what it looks like, the headlight has actually just been pushed back and bent the headlight support (which .. somehow... crushed the guard in). I guess the headlight plastic is strong stuff.
