your injector size is wrong, 260cc is smaller than factory, double check what you have

and what on earth is a garrett T2? where did you find this from?

how much power do u want to make

First thing's first upgrade those injectors! 260cc would max out before 300hp, which is no use to a GT30 turbo. Go for 500 or 750cc depending on how much power you want to make.

Don't get a T28 flanged turbo, go T3, skylines hate small turbos. What's the deal with your turbo at the moment? Are you saying its a highflowed stock turbo with the CHRA of a GT3076? If so, just order the front and rear housings to suit, and make your own genuine GT3076r! Get the .82A/R external gate rear housing.

As for wastegate, 44mm Tial should do the trick, Tial gear is cheap and good quality from the states - take advantage of the good aussie dollar atm!

sorry about the errors i have a gt3076 gcg special with the skyline rear housing on it .63 ar was thinking twin scroll to keep it responsive and .82 to give it some top end legson current build lookin at a safe 280

but who knows after a engin rebuild 350 + but i dont want to be messing with turbo again

made the mistake last time and not doing enough research and rushe my purchase base on price and car sitting at tuners broken

thanks again

paul stop being a hater lol

Hater?

Realist mate. I ain't going to tell you that it'll make 350rwkw+ if it simply won't.

As you said you don't wanna touch the turbo again, you'll wanna work out now if you want 350rwkw+ or not, thats the point you kinda missed.

.82 rear internally gated low mount will be ok for 300rwkws. The twin scroll's available in .84, I personally experienced no difference, might change with a twin scroll manifold.

If you want to crack a good 300kw, save yourself the cash and buy the .82IW garrett housing from GCG.

Drop the car off to a good mechanic and have them fit the housing and make you a nice dump for it. Make sure you have the big can actuator in say 18psi to suit.

Cost you under 1500 with a new tune and all I will say, 300rwkw and a massive smile on your face.

For reference if you go a 6boob twin scroll you are going to put a hole in 5 grand. (2 gates + manifold 3k alone)

change the turbo housing from t2 to t3 to keep Paul happy :)

Your talking about some serious mods here, I would expect min 12k to have anything actually running and the potential for a lot more $$.

I agree with GTScott, put a 0.82 garrett housing on it with the appropriate dump pipe (GCG can sell you this) and that will get you a nice 300rwkw for very little cost.

true twin scroll manifold needs 2 wastgates you need to add labour and other un forseen costs that could arise and tune will probally be a bit more, just change the rear housing and put a gate on the manifold and get a retune the stock manifolds have been proven to flow 300KW so your just spending money you dont have to.

Plazaman plenum looks great i had one ... cant use it anymore though due to motor change....really makes changing plugs so much easier :P

I got the manifold twin scroll turbo, and twin 38mm waste gates, and lines for closer to 4k from Kyle at 6 boost.

    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
