Hi everyone. Im saved up a bit of cash and want to mak the 33 go that little bit harder. I have recently read here that ppl dont advise running more than about 12 psi on the stock turbo (i currently have the boost set to 10) If i wanted to raise boost levels to say 15-16psi is it better just to hiflow the stock turbo as opposed to buying a new one which seems like the much more expensve alternative. How do ppl rate hiflows?

Have you installed an ecu?

With a highflow, you will need an aftermarket ecu, then fuel pump, then injectors to get the full potential.

Buy an ecu first, this unlocks sooooo much hidden potential within the std motor/turbo.

I have a hi-flo and new ecu...basically get urself something like a PFC first. also look at the zorst, AFM etc before u bother i guess. few post aboutt what to do first.

yeah ok cool. i already got exhaust and cooler and was gonna get the power fc now with the turbo. How r u finding the hiflow? is it noticibly lagier?

i would definately recommend the hiflow option. good power increase over stock. i got a vg30 single turbo exhaust housing adapted to mine for abit more top end :down: result being 346hp(258kw) at wheels on 15psi. u make up your own mind !!

    • Sometimes you need to pay good money to get quality work done.
    • I found they are significantly more expensive than other workshops (this is when I went to ask about a tune), heard they are good though.
    • On the compressor side it looks like the best, if your head setup will support doing 100-110lb/min at 30psi-ish boost.   The G45-1350 compressor looks ideally better if you need closer to 40psi for it, given both the G40 1150 and G42 1200 look like they'll be around the 100lb/min mark at 35psi and dropping from there.   Bear in mind the turbine sides are all different between those three turbos, so that COULD be an influencing factor for how they all perform in the real world as well.   Not sure if you've made a conscious decision to only look at Garrett or not, but at least on paper the XRE7169S matches or beats those other three at everything from 30psi up and just going from wheel size alone likely to be at least as responsive as the G40 1150 and seem to behave closer to G42s in terms of turbine flow.
    • @Lithium  looking for a turbo for my Rb30. Want to make sure I understand this correctly.   If I want to stay 40psi or under my best choice of these 3 is actually the smaller G40-1150 ?
