Hey guys need to upgrade my hairdryer....oh sorry my stock turbo on my rb25.....lol

Thinking of putting a gt3040r with a 0.63 rear housing so it can be more responsive. Searched it already but no luck.

Its a 600hp dual ball bearing turbo. Want to know how responsive its is and when full boost comes on?

Who ever has this info it would be most appreciated. Basically I want to increase my present 211.8rwkw to about to 260-270rwkw. HOWEVER, response and streetability is my first and foremost goal! Dont want a snail that has great peak power but poor low-mid range.

Any help would be great? I do not wish to hi flow coz its around the same for a new turbo these days.

pfc injectors, pump, z32 etc etc.

all needed anyway

i have the HKS version of the 3040

291rwkw on 18psi with poncams

i have the 1.12 rear housing, so fairly laggy at full boost at 5000rpm

without cams you will still get boost about 4000 rpm-ish with that housing.. cant say for sure,

If you think you need 'em for the 71, your gonna need 'em in spades for the 40.

You are right though!! :)

CAn you elaborate on this GT3071R

What size ex. A/R should i use?

What is it rated at?

Do i need a custom dump? How much?

How much is this turbo cost?

Is anyone running this turbo on a RB25? If yes please state mods and power made.

PS: I will put a pfc in with the upgrade and run about a bar of boost. I will in the future place some bigger injectors and z32 afm (or maybe pfc-jetro)

Thank You In advance!!!

I'd step down to the GT3076R (HKS GT3037 56 trim) or the GT3071 as mentioned. The GT3040R is a mismatch turbo and will be too laggy for your power targets.

I'd go one back again, 250-260rwkw is smack on the peak for the GCG Unit, and it gives insane response with great top end.

For the sake of having 250-260rwkw as opposed to 260-270rwkw (which can be attained by playing with dyno numbes if you need the sheet), i know what i'd choose for the RB25.

try doing some research, you have been handed some info on a good choice.

price will depend on where you get it

custom dump pipe = YES - depends where you get it made

response - go for the 0.64

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
