    Quick question :)
    Has motor got forgies?
    These turbo's are good for max 28 psi.
    stock cast pistons WILL die at over 22psi guaranteed.
    Find out before going crazy with boost.

    Also the 650cc injectors will NOT be sufficient if u decide to run these turbo's at their max boost capability.(no head room)
    Just a couple of points id like to raise :)

    P.s congrats on raising Fates car from the dead :)

    She's built to Drift


    No the motor is still running stock pistons, at this stage.
    Im building it for Drift. Would love to see a 300 carving it up with all those 180's, silvia's n R32's. Just wanted to do a lil somthin different to the average Joe.
    Not planning on running big boost yet. I was planning on running no more then 350rwkw for drift. How safe is that on stock pistons???
    Has any 1 out there had much experience drifting the Zed???
    Any particular mods i need?? any tips???
    Apart from the turbo's the immediate mods were throwin in are the hicas lock bar, coilovers and rear strut brace.
    Seeing how the motor has already done 200,000km I was thinking if it starts playing up down the track then ill have to break another piggy bank and do a full engine rebuild. Maybe buy a fresher engine then up grade all the internals that are required for running the higher boost.
    Thoughts???
    Thanks for all the feed back!!

    Well Caz sponsers a Z32 drift car. Has a dirty great V8 in it though :p The guy who owns it is Thunder (name on forum) from SurFlo exhaust.

    Maybe ask him?

    One thing you might be interested in is a NA diff which has a shorter ratio and you can get Nismo clutch 1.5way LSD's quite cheap. Street to Strip should be getting some real good prices for everyone soon. Approx $600 is my guess. The Z's have a viscous type LSD that wouldn't be ideal for drifting.

    And another thing, your car is a 2 seater, so nice snappy chassis for you! Lots of spins I reckon :p

    350rwkw for drift. How safe is that on stock pistons???

    Forged pistons are the way to go, that engine wont last long drifting @ 350kw.

    If ur going to drift with those sort of klm's on the motor limit the boost to about 20psi. those turbo's should put out a little over 300rwk at that boost.

    24-26psi is a good sweet spot for them :) but get forgies first(rebuild) :D
    Get in touch with Caz for info/specs regarding zed setup for drift .
    BTW they are not the easiest cars to to do it in either hehe.

    they're good motors but not that good. bumping off the limiter for 90 seconds each outing. id be looking at forgies for sure

    So 300rwk should be safe

    Sweet. so 300rwk should be fairly safe on the old girl... Anywhere around 300rwk would be sufficient to start with. Then down the track as i get into it a bit more im thinking we'll go the rebuild with the forgies.
    Dont really want to go all out, $$$ ,until i get out there n see how much i like it.
    Pretty sure ill love it though.

    Cheers

    drift

    I went up to winton with my mate (cleary) name on forum. both me and him have na's and we where going alright compaired to the other guys out there .....kind of :rolleyes: the car went well the temp was fine just the oil temp was getting a little hot and had to wait for it to cool down again. 300's are a nice car to drift the steering is different then 180 but heaps of fun.

    Problem 1 with turbo

    Hey all!!!!

    Started pulling the turbos off and found one of the fan/wheels missing from inside the right turbo. Ended up finding it in the exhaust.

    Would this issue be sufficient to stop the engine from boosting properly??
    Here's a pic of the left one which looks ok.

    [​IMG]

    Also i found the the right dump is made up of two pieces which are clamped together. Is this set up ok???

    [​IMG]
    [​IMG]

    Where as the left dump is a single piece

    Thoughts??
    Cheers

    That's a V-band clamp, very common on the rear end of large turbo's. Like the one I've got :zlove:

    Thoughts? she's rooted mate . :D

    seriouisly tho its good its on teh hot side so none of hit has gone thorugh and shagged the motor

    Is this a common occurrence with turbo's?? What courses the fan to come off??
    Apparently the car was running 12psi when it blew.

    Nope, not common unless it was a ceramic wheel or somone forgot to do the nut up...

    Hey man, grats on buying fate's car. You have quite a reputation to live upto lol :D.

    I can only imagine what fate is going through, if i had to sell my car i would be in tears. But all must come to an end eventually, good luck with the car.

    I think the hardest part on drifting the z is lowering the center of gravitly at the back. it seems to be its biggest downfall.

    You won't even need 250rwkw to drift it.

    There's your prob Fate :p
    Yeah not having a turbine is more than enough to lose boost as its just blowing exhaust straight through. Because its not spinning anything then the intake fan causes big restriction. Also with it only boosting one side, the air is just blowing back out through the balance pipe and back to the front again.

    Its too bad you didn't just pull the turbo's Fate. Such a small problem lead to the sale. :(

    Quit your jibba jabba and buy another fool :D

    Thanks for all the feed back so far guys!!!!


    Can the center of gravity be countered buy the installation of coilovers n dumping it??? Or is there still just to much weight in the front compared to the back??
    Cheers:D

    I would replace all the rear subframe bushes with the energy kit.
    It will make ur handing rear end wise very direct and responsive .

    Any play in the rear end will lead to sloppy unpredictable handling.

    Up to you tho if u want be that anal :)
    I believe that ur suspension should be very stiff for drift , u don't really want weight transfer that leads to traction, u want the opposite setup of a Race/track car :)

    You still need some kind of traction or grip, just gotta be set up right so you can light them up, but without any traction mean no high speed drifts. You'd spin out all the time. Either that or you can only drift at Archerfield bahaha.

    Stiff rear end, semi slicks up front and TOYO TPG's on the rear ;) or a good set of treads that are fairly predictable. I had a good set of Hancooks. Still got them but they're just burnout tyres now until I get another set put on.

    Safe boost levels on stock internals???

    Hey Guys!!:D
    What would you consider to be the highest boost I could run safely considering i have stock internal??
    I have most of the other mods needed to run around the 300rkw + of power as far as im aware. Its just the internals that im concerned about at this stage.
    Performance mods include:
    GT675RS Turbo's
    650cc injectors
    Larger side mounts
    3" dumps and exhaust
    UAS Ported, honed and Extrude Exhaust Manifolds
    Koyo 53mm Radiator
    19 row oil cooler AMEC
    Greddy - Profec Spec B S2 Boost Controller
    Custom Chipped and Tuned ECU (stock ECU)
    Cheers
