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.

    • Impossible to remove the housing while turbo is installed on the manifold on the engine. So I have to do it anyways. I plugged it so there will not be any debris in there. Will vacuum aswell 
    • would a r34 gtr hood line up with gt/gtt stock fenders? after latch, front bumper and hinges are swapped for gtr ones? or would the fenders be too low or high in relation to the hood surface? ( I believe seeing somewhere that gtr front fenders use some type of riser for the sides, but do not know how that relates to stock gt/gtt fenders.)    
    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
