Chris, the GCG hi-flow is $1950 and as SK mentioned, they bold straight back up exactly how the old one came off - no need to worry about new manifolds, dump pipes, or oil and water feed lines.

From what I've read on their website (link HERE), they replace the ceramic turbine with a steel wheel, they put in a better flowing compressor wheel, and replace the ball bearing unit so there's little or no worries of that ever being an issue.

This is the route I'll eventually be taking when I scrape some money together. I'm lucky that my cousin had a spare turbo off his old motor (he replaced the motor in his R-33 about a year ago) to give to me in the mean time. When I give him back his turbo he'll probably be getting the GCG upgrade as well.

Removing and replacing the turbo was pretty easy - as long as you can remember where everything goes (use a camera if necessary), then the only problems you should have is accessing some of the nuts, bolts, etc, as the space is a little bit tight between the turbo and the passenger-side strut tower.

Best of luck with it. :blink:

Cheers mate. I'll let you no how I get on :)

Hmmm....

So with -

- GTT I/C

- Highflow

- 12 psi

- Fuji Catback

- HKS Panel Filter

- IEBC

- DFA

What soughts of power figures am I looking at there? Would it get 160 - 180 awkw?

Same as the above, but with a split dump and 1.1 bar = 200 4wkw.

:unsure: cheers :D

Bleed Valve. Piece of shit though

Obviously was! Cost you a turbo, me thinks! (sorry!)

First thing I did was ditch the Turbosmart bleedvalve (set at 10 but overspiked) and put in a Hybrid brand EBC. To be safe. Im running 12psi now (approx 11.8 actually is the top it gets to), but generally get off the gas when it gets to around 10psi.

With a hiflow with steel wheels, forget the low boost stuff. Thats for ceramic wheels. Hi / Lo settings should be 15 / 12 and that should be safe for the engine *with all supporting mods.

*GCG turbo, air filter, GTT 'cooler, full exhaust, EBC, SITC, fuel pressure regulator (or injectors), 14psi would surely be 200awkw, with a nice and safe tune.

My opinion only (worthless!!) =P

Im led to believe the GCG hiflow is best suited for optimal power/torque to be run at 15-17psi on a internally-standard RB25DET (use a EBC fellas!), can anyone confirm?

I would have thought running 12psi would be a waste on a hiflow'd turbo. Maybe talk to GCG and ask 'em?

10psi is too low tho for a hiflow steel wheel turbo (if you've got the supprting mods - which you have). Good for ceramic standard turbos but a bit of a waste on a modd'd Stagea!

Go 14psi, nice and safe tune on the PFC Alex, you've got the supporting mods as such, so it'd be perfect for everyday use - remember your right foot is the rEaL boost controller.

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
