hey guys,

just after some advise here as iam going to be hiflowing my turbo this week.

i got 2 choices

choice 1: (standard Hiflow)

this is pretty much standard, and they guy said will get me about 250 atw once its done.

choice 2: (PU Hiflow)

this is a bit diff to the standard, bigger housing n such and will get me about 280 atw

The guy said standard is more responsive and will spool at about 3.5, 3.6 and the PU will spool at about 4k revs

my car is a daily and i like to have fun here n there, not a fan of track n calder park n that.

i dont really knw much about turbo's so though i ask the experts here ;P

so which 1 should i got for?

What are you asking mate? Which one to go with?

For a daily, go with the responsive high flow. You might get bored of it down the track but its better to go incrementally than for big power straight away, both for getting used to it and deciding when enough power is enough. For a rear wheel drive daily, 250rwkw is pretty well fast enough particularly if power delivery is spread across the rev range. There's not many "traction holding" situations where you'll need more than that. Going straight to the lag of the PU highflow will piss you off if you're used to standard response...another reason to step up incrementally.

280rwkw with boost coming on 4000rpm is average. Should be sooner than that for that kinda peak.

My GT30 (600hp version) was on 4000-4200rpm and was 270rwkw @ 17psi, would have been over 300 with 20psi and that was with a .82 rear housing, not a machined OP6 (which is smaller)

ask 5 people who have both versions and compare

the std GCG hiflow has been bulletproof for years and should have lots of known users

the PU hiflow is relatively new, different bearing type, and may have other unknown issue, ask 5 users who have one

did you fit it yourself or a workshop - if you, how hard, any mods to make it fit, how long if workshop - how much $ to swap

did you send yours away and then get the hiflow back? how long did it take

any install instructions come with it

      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.
