    Well, I'm fairly new to OT, but I thought I'd share my upgrade experience. Did this earlier on in the year. Was a nice little project.

    My fabricator friend and I have installed a Garrett GT30 with .63 (vg30) housing.

    Here are a heap of pics of our progress.

    Car on the hoist..

    Looks like I've been running some fuel additives.....

    This is my mates own car.. lol I rode in the back for obvious reasons (he's getting his seats covered)
    [​IMG]


    The Q45 AFM is a LOT bigger than the standard one eh?

    it blurry but, where is my turbo?!! lol
    [​IMG]




    The GT30 on its new home, adding the oil and water lines. This is about the hardest part!! They are bastards to organise\make\get on

    New pod Divider.. lol well the template

    Turbo on and a few adjustments

    A nicely wrapped dump pipe. (my mate made it from a pair or flanges and some bends). The thermal wrap is wired on.

    The dump is bolted on and stray lines hooked up
    [​IMG]

    The hole in the Divider is cut (with a plasma cutter.. fark they are cool..can blow holes in all sorts of shit)
    [​IMG]


    Cleaning up the sharp edges..
    [​IMG]


    Getting there...
    [​IMG]


    Tightening a few hose clamps
    [​IMG]
    [​IMG]




    ok, heres the finished product.

    anyway... If anyone has any questions at all about this upgrade, ask away, I'll answer my best.

    This took us 2 full days.

    nice

    whats the rest of the setup?

    the turbo should make 275 rwkw(370whp) @ 1 - 1.2 bar


    ....get an av ;)

    Rest of the setup -

    Apexi Power FC + Hand Controller + FC Datalogit and laptop Tuning Software
    Nismo 555cc Injectors
    600x300x76mm FMIC
    Full Stainless Exhaust, Hi Flow Cat, 3inch to cat,3.5inch to First Muffler, 4inch to Cannon
    Q45 (90mm) Air Flow Meter
    4 inch Intake (To Suit the bell mouth fo the Turbo)
    Standard Internals
    $22 Bleed Valve set to 16psi

    Currently Making around 230rwkw, because we only have 95ron fuel here. Any higher octane fuel is 4 hours drive away which sucks. We've been waiting for 98ron for a long long time. I know a few people with the same setup pushing 260rwkw - 270rwkw, but with 98ron fuel. You can advance the timing a fair bit more (skylines seem to respond very well to timing advances), and uping the boost a little pushes this turbo a little closer to its efficiency range. Any higher than 18psi in a RB25DET is suicide though, as the rods are too weak.

    Another dude managed 280rwkw with this setup and cams, on 15psi (1.1bar) but was limited to 280rwkw because of the exhaust housing. What we've done is grabbed a genuine Garrett GT30 Core, slapped a .7 Compressor cover on the front, and ground out a standard Skyline Exhaust housing to fit. This allows it to bolt onto the stock exhaust manifold and the dump pattern to remain the same. Also reduces lag because its a .63 rated housing, which is fairly small. Downside is high back pressure in the exhaust manifold causing the power to drop off up top, and also encourages pinging. Very Torquey though.

    The guy with the cammed setup went to a .86 exhaust housing and made a big step into the 300rwkw+ territory. Became slightly laggier though.

    I'm thinking about investing in water methanol injection to solve my bad fuel problems, from these guys (http://www.snowperformance.net/products.asp?id=1), with a full saftey system to prevent my motor blowing to pieces from detonation if the water ran out or stopped for some reason.

    all the saftey systems do is detect water pressure drop \ stop etc, and open a solinoid that reduced boost right down to extremely safe levels (16psi down to 7psi in my case)

    Kit is a bit of coin though. Will have to save a bit of cash.

    so far I like this build. By using the slightly smaller GT30 you will get good response. No aftermarket fuel pump/surge tank setup?

    who tunes the car?

    thats good power mods for now....work on improving the fundamentals of the handling and stopping of the car if you havent already

    Forgot to mention those.

    Got a Walboro 225lph pump in the tank (no surge setup)
    JIC Coilovers sitting Very Low (rough as hell but handles like its on tracks)
    18 inch Rims (makes it a rought too) 235 wide rubber.

    GT30 goes really well, thinking about the GT-RS though, apparently puts out just as much power but comes in a bit stronger.

    I'm ever looking at the GT30r, as its got one less blade on the compressor wheel, requiring less shaft torque to spin it, thus reducing lag.

    Hard to find the perfect balance between not too much lag and enough top end.

    I love how the FMIC stick out from the bottom, I know someone with a GVR4 whoes does the same thing.

    RBs can't handle more than 18psi? I thought they were built like brick houses...

    negatory.

    GTRS is rated at 400ps. Even though HKS under rate their turbos, thats still a fair way off 550 horsies

    nah, I wish.

    Toyota Supras - definately - built like brick shit houses. They come with a forged bottom end straight from the factory (the 93 and onwards). One of my Friends has a 93 Supra, took the twins off and bolted on a T51r (around 1100hp) with a 1.06 exhaust housing. Made over 400rwkw with water methanol injection, ECU, injectors, full 4 inch exhaust, bigger fmic, etc. And thats without cams! He's got 272 cams ready to go in... I can see 450rwkw + soon. Ran an 11.7 at 122mph.

    RB25DET's have cast pistons and weak rods. They are as thin as hell. Run anymore power than say 280rwkw, and you're running the risk of bending the rods, or if you have a bad tune, you'll detonate and crack the pistons in half. They also have very weak ringlands.

    But hey, from the factory, R33 skylines have 125rwkw. I've got about 230rwkw. People are making 280rwkw safely. Thats a damn big increase in performance. So yeah, now that I think about it, they are tough little buggers. 280rwkw with drag radials is also good for 11's if you can drive \ launch.

    Bingo.


    I guess now that I think about it, 370 AWD HP is nothing to scoff at, since that is over 450hp at the crank. I guess I was just under the assumption that it could take more.

    How about the RB33T(T)?

    RB33T?

    hehe whats that?

    The R33 GTS-t Turbo engine is a RB25DET
    The R33 GT-R Engine is a RB26DETT
    The R33 non turbo is a RB25DE

    I have a RB25DET

    Wish I had a GT-R...they are such a better engine. Twin turbo, bigger capacity, rev harder, balanced so well...

    nah, I'd use it as a daily driver :)

    I'm currently getting a RB30 block to attach a RB25DET head to. Will go very nicely. back in the late 80's, Holden (australian car) released a Commodore with a nissan motor. RB30, was a 3l block, with a single over head cam, 2 valves per cylinder. They made a turbo versino and a NA version.

    I'm making a Hybrid as a fair fwe people do. Slap on the twin cam head, from the RB25DET (pretty much bolts straight on) and it becomes 3.1l. Then set up the compression to 8.5:1 and you've got an awesome motor.

    Bought a block off my mate for $50 lol.

    Just nee to get it acid dipped, and prepped, get the rods and pistons sorted, bolt on the head, and drop it back in the car.

    Since the RB25head is natural to my car, there is absolutely no wiring needed at all.

    Correct me if I am wrong, but aren't all of these engines made by Nissan?
    RB30ET, RB30DET, RB33DETT, RB25DET and RB20DET.

    I Googled "RB33DETT" and I got results.

    Did it never come in the Skyline?

    hey man did u have to add a block between the manifold and turbo? i had to run one bc my housing was gonna hit the mani. my turbo is a gt35r though...im waiting on injectors and then ill get it tuned for around 500 horse... car looks nice btw. also, u may want to put a flex section in that downpipe!

    hey dude

    Yeah I had to put 2 x 10mm plates in to space the turbo away from the maniold because the compressor cover hit it.

    Do you have any bottom end work? Mines still standard until I get this 3.0l built.

    What do you mean by flex section?

    Go somewhere in the middle of your downpipe to allow it the flex and move as your engine shakes around during driving. Most times, if you don't have one, you can crack your downpipe in some place.

    hehe wish the engine made enough torque to flex everything! Its a tough assed downpipe, and its been like that for years now so I don't think I'll have any trouble with it.

    When the 3.0l goes in, will definately look at it!
