Advise Needed Please

[YF34R]

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.

what are your supporting mods?

[YF34R]

once i get the turbo ill looking to upgrade:

nistune

coil packs

injectors

fuel pump

i have a FMIC atm and a catback exhaust

[joeyjoejoejuniorshabadoo]

go the smaller option... response is more fun than power.

you could squeeze 230rwkw out of your stock injectors/pump/afm

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

I've been using the gcg hi flo for 5 years,16lbs of boost daily,no probs.

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

[YF34R]

i got another Question.

say i get an EPA right and i have the hiflowed turbo.

are they ganna pick on and i got get a stock 1 in?

[R31Nismoid]

No.

Have a think - how could they possibly know the internals are changed when it looks the same on the outside?

That's the whole point of doing a highflow turbo!

It was sent to gcg,came back in a week mechanic fitted it straight on,it looks stock on the out side,but inside steel wheels and bored out.

Oh my mech gave me mates rates, $1585.
