SargeRX8, your obviously not using the standard turbo if your pushing those numbers, do you know whats on it?

The guy had some turbo rebuilt, I think he got the turbo from a VL, and had a company in lane cove I think put Garrett 3071 ball bearing turbine into it. They said it should be good up to 18 - 20psi but he would have to change the headgasket on the engine and a few more internals. Injectors and fuel pump are good to go but the coil packs may get too hot and need something better suited. The guy I bought it from has been running it how he has for quite a while and never had any issues so it should be fine I guess.

I'm planning to change the turbo as I personally do not feel comfortable running rebuilt turbo's.

This is what I want to get. Its a direct bolt on for the standard manifolds and dump pipes on the r33.

I dont know what it is but these are the specs lol

Power rating: 560HP

Turbo Housing: .70AR

Compressor Housing: .50AR

Flange type: T3

Cooling: Oil and Water (I heard it requires abit of work to setup the cooling)

Bearing type: 360deg Thrust Bearing

Actuator: Internal gate.

The guy claims this turbo will handle 16psi with a breeze.

Interesting...Why dont you feel comfortable with your currenct turbo? What is the current turbo that you have like compared to say the standard turbo? In terms of response and power etc. When does it start boosting and when does it have full boost by?

The reason is reliability. I don't know if its the turbo or my profec II boost controller which isn't configured properly but very rarely when I've hit full boost, I feel a drop in boost at high rpm until I move into the next gear. The problem seems to have gone since Ive sat there for about 40mins configuring the controller and I'm hoping it stays that way. Another reason I'm concerned is how much the parts can take. He told me that the turbine he had installed in the turbo is a very strong turbine and thats what Ive read but the turbine was designed for another housing and because its a rebuild, it will never be manufacturer standards. I'm going to rip off the pipe on the front of the turbo one day to see if there is any shaft movement.

I start creating 0 vacuum at about 1500rpm and boost will peak at about 3000 - 3700rpm on low boost and high boost respectively. Before I bought this car, I drove quite a few skylines. The response is ALOT better but this could be due to the fact that I hit boost earlier than a stock car and also the fact that a stock skyline peaks boost above 4500rpm. The power is insane. High boost, the car will not stay straight and I will burnout in first and second gear at high rpm's. I can't launch the car coz I tried once and just sat there doing a burnout so I just do slow starts then punch it.

Alot of people say Ive got nothing to worry about, but its my first turbo car and I just haven't yet adapted to them and to what they can do. The first time I bought it and hit boost I honestly thought something was going to break but the guy is like you get over that feeling quickly once you realise how strong the car is and how much more it can take.

Lol hahaha sounds like alot of fun and sounds like a good turbo. Is it straight bolt on to the standard rb25 manifold?

It is alot of fun indeed but very bad on petrol haha. I like the performance of the turbo, I just hope I can rely on it.

Yeah, its a straight bolt onto the old manifold, just needed a new dump pipe I think. The heat shield for the turbo had to be taken off though.

Lol haha its all good. I went up to the 4 and Rotary Nats in Auckland New Zealand at the end of Jan and caus I lost my license my mate drove my car and my cars shocking on gas. The whole trip was from Friday to Monday and it costed around 600 dollars just for all the petrol we used lol. So yeah not really concerned about fuel as I earn plenty and I accept my car will use lotsa gas as I have a very trigger happy foot lol haha.

If you ever want to sell you current turbo let me know. I might be interested to see what its like. Love the burnouts lol haha.

Haha sounds like an awesome trip man. Yeah I don't care about the fuel consumption because every kilometer I drive is so f**king fun haha. I just took my brother for a drive, boost and turning is so much fun ahahaha. Just hold first gear, tap the throttle and you get a sexy slide.

Ill keep you informed. If I find a suitable turbo which will handle 17psi and be a direct bolt onto my dump pipe and manifold, ill upgrade and let you know!

you do not appear to understand how the factory boost control system works, if you believe your turbo that is capable of 240kw is more responsive than the stock turbo. which when using just a simple boost T or the always high boost mod will be all in before 2500rpm

you also need to look into your suspension/tyre/driver setup, you shouldnt have serious traction issues when launching properly in 2nd gear or when changing from 1st to 2nd.

I don't really know the mechanics behind it but I know, from what Ive driven, my car does pick up speed at lower rpm quicker than a stock r33. That's all I was trying to say in my last message lol.

Its not too bad. The ass of the car just slides abit from side to side when I'm in the higher rpm range. Ive got bilstein shocks with whiteline springs. I don't know how to adjust the shocks, they might be a little stiff. Tyres are KU31's with about 90% all round. I think I need to deflate the tyres abit so they sit abit flatter.

I'm hoping strut bars will somewhat help to keep the car flatter.

Haha I definatly know what you mean. Its all ways good fun to slide out haha. Yeah every bit of gas ya put in is worth it lol. Sweet that will be cool. Caus I would definatly be keen for a simple upgrade.

If you want to buy a new turbo I would recommend the Gt3076 ($2185 from NZ Performance) but if you want to spend less you could buy my GCG highflow for say $800 or $1000 c/w split dump front pipe - I'm making 245awkw but due to upgrade in next week or 2.

Have also noticed now thar garrett make replacement ball bearing cores. Does anyone know much about these? Are they a straight drop in replacement and if so which one would be best suited for around 230kw at the wheels? Does it require any modifications to the turbine or compressor housings?

Cheers

Read the post above yours by KiwiRS4T.

The GCG highflow is a garrett ball bearing core in the standard turbo shell. That is perfect for what you are talking about. Will make more than 230rwkw easily. Sounds like an excellent price too.

the GCG is a good unit, they dont play games there. 800 is a decent price too :thumbsup: you may want to snap that up Kailaas

they charge 1950 i think? for their hiflow service.

    • Update for the sake of closure   Ended up getting the intercooler piping all sorted, new plugs and yellow jacket coils, and she was idling mint until it warmed up while I was bleeding the cooling system. Found the misfire to be localised to cyl 3 by unplugging coilpacks, ran a compression test, that checked out, then decided to get a mate to check if that spark plug was firing out of the motor. Upon cranking it over, with the injectors disconnected, the car actually fired and ran on a couple cylinders and heaps of fuel came out the top of cyl 3 I'd say that injector's either spraying incorrectly or spraying far too much, which is fine as I'm planning on replacing them anyway I'm planning on making about 250kW on flex fuel, and have a set of 1000cc injectors from ozautosport, obviously overkill but I'm planning on building the motor and running more boost further down the line, do you reckon they'd be too big for a smooth idle on 98? Thanks for the replies gents, much appreciated
    • I'm confused. You said you want to "remove the clear coat from most panels" but it sounds like you are actually doing a full respray? Few random things to add -  If you chase the blistered paint with 120 grit, I can almost guarantee you'll chase it down to bare metal (that's fine). But if you paint the car from here, you'll have nice little indents where ever the blistered paint was. The new paint won't magically level out the low areas, you need to fill them. Which leads me to the main point I wanted to add, make sure the whole car is flat before you paint it. All those areas with blistered paint you sanded out, make sure to fill them and triple check they are flat with a block guide coat. I'd also check the whole car is flat with a large block and guide coat but yeah up to you if you want to go that far.   
    • 300hp (225kw) is barely outside the standard turbo's range with a bit of extra boost in it (200ish). If you are going to change the turbo you should aim for 250-300kw (330-400hp) to make the expense worthwhile
    • A couple of things, firstly omg that turbo is expensive! $3,000 USD for dinosaur technology is robbery. You could buy a G series turbo and have a good amount of change instead.  If you want a good budget option, have a look here - https://hypergearturbos.com/product/rb25dethighflow/ If you are keen to spend more, have look at the modern turbos, Garrett G series, Borgwarner EFR, etc. Have a look at the RB25 dyno results thread for inspiration.  If you upgrade your turbo to something that will support the 300hp you want and only "probably" have Haltech ECU, your car will only "probably" run. Actually, no it won't run. You are going to need the ECU and injectors at the time you do the turbo upgrade.  No thoughts on "this much boost" as you didn't say how much boost that actually is. Having said that, plenty of unopened RB25's making even more power then what you are chasing.
