Hi, I've just been offered an R33 Turbo that's been machined on the front inlet part and then the rear cast part has also been opened up a little too... Can get it for $700 as a complete kit with all new blue silicon hoses. Just wondering if that is a good price, the bloke recons to machine a turbo in that way it would cost upwards of a grand. It will be going on my R34 Neo, would this be a good upgrade for the price?

Also does anyone have any idea what i'd then get for my standard R34 neo turbo?

Don't do it. Unless you can know what wheels etc have been put into it, it's not worth a single dollar. Also, the R33 rear housing is smaller than the R34 rear, so even though it has been highflowed, you would be better off sending your R34 turbo to Hypergear and getting it flowed for not a lot more than the $700 they want for this other turbo.

I was talking to a guy from GCG Turbo's yesterday at Jamboree about high flowing my r34 turbo and he said after its machined and replaced the compressor etc. ect. it'll cost upward of $2000+.

Don't know how true it is but its something to think about...

I recon ill be going the $900 option... Don't need anything too Fancey just a little better than stock for now and kinda got excited at the price and look of the high flow... It was coming from my bro on law whose a.pretty good salesman haha...

I paid $1800 for GCG to hifghflow a GTST turbo about 3 or 4 years ago - wouldn't do it again - the Hypergear seem better value for less money or at about the same money or a little more you can get some good new turbos (although you may need new lines etc).

I've got a hypergear high flowed r34 turbo and once I get my ecu issues sorted, I will hopefully be putting it in. The dyno graph in the hypergear thread show it on an r34 putting out 260rwkw on 17-18psi bleeding off to like 14ish psi up top.Ill be hoping for about 240kw or so on my r33.

high flowed turbo do make noticeably more power on stock ECU, you can run about 10psi of boost without upsetting the factory tune. How ever it doesn't make the full potential unless you have aftermarket ECU, injectors and the rest of supporting mods. The best is to get the turbo installed, then have fuel mods done at your tuners with car tuned on nistune chip. I've been told stock afm support up to 250rwkws, so Z32 AFM might not be necessary for the high flowed turbo.

No point wihout the Nistune. Depending on the turbo you will also need a Z32 afm and bigger injectors (and you should replace your fuel pump with a new and better one).

Since you will also need (if yours is stock now) a FMIC and at least 75 -80mm turbo back exhaust. If you're on a budget do these first with the Nistune and then get the turbo, afm and injectors and retune.

Ask about the specifics, receipts etc. I bet it has a journal bearing core - nothing wrong with it though. If you can prove it really is a high flow, then offer him around 650.

Its definitely been “hi flowed”, but as for specifics we don't know... He bought an economical right off and it was on the engine in that car. Thats all we know. The seller is my bro in law so i know he's trustworthy and not rorting me.

yeah , its so easy to carried away buying a turbo..you start of looking at a budget hiflow, then realize for an extra few hundred you can get more power..

But in reality its not that easy..cause there is always extras needed to make that power...

looking back at my own mess, a budget hilfow and an ecu with a good tune is where I should of stopped..you can keep stock injectors and afm and still make a comfortable and zippy 220kw without worrying about destroying your driveline every time you sink the boot in..Plus it will still look stock should the popop start poking there noses in your business

2500$ will get you a 220kw quick and easy to maintain car

5000$ will get you a 280kw weapon and alot of headaches

Its just so easy to get carried away upspecing everything....

Direct from the RB25 dyno thread:

R33 Series 2 5spd manual

Stock RB25det series 2 engine

-3" turbo back exhaust

-Hypergear Hiflow 21U housing (R33 turbo hiflow)

-stock afm

-Pod filter

-Stock injectors

-Frount mount intercooler

-wolbro fuel pump

- Ecu tune by Toshi (by me)

Makes 263rwkw on only 15psi

    • 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.
