there are SO OOOOOO many thread on turbo choice here, and would like to get some peoples experience with turbos down here ...

I'm thinking of a new turbo in the next few months, and have read the whole high flowing v BB turbo threads ...

I'm in agreement with sydney kid about the whole useable power thing, and a turbo is absolutly no good to me if it does not come on boost until 4500 rpm ...

i'm looking for something to produce about 17psi psi, and start to come on boost at around 3 - 3500 rpm (ish)

I rarely touch near the red line, doing most of my hard driving in the 4-6000 rpm range ..

Its a S2 GTS-T with a hks pod, and turbo back 3", emanage is on its way ....

so what is the best turbo choice for this application ???

Well your not after a power goal or 1/4mile time etc from what i can tell with your first post.

If you want something that kicks alot harder than the standard turbo, pulls all the way to redline, and spools about the same as the standard turbo.. Then either go for;

Highflow

HKS 2530/40 or even 2835 if you want more power

Garret GT28R

Otherwise the GT30 would be great, although these are rated at about 500hp which means you need to upgrade a few things first, IE injectors, fuel pump, ecu etc but that comes with any new turbo

Check out GTS-t VSPECs graph in the dyno graph thread running now to see why.

I did and this is what I saw..........

Read that power graph carefully (note that it STARTS at 90 kph) and you will notice that it has LESS power up to 106 kph than a basically standard R33 GTST (refer 05YKO_r33 ‘s power graph in the same thread). By “basically standard”, it has an FMIC, 3” zorst (inc dump) and a boost controller, it has no fuel or ignition timing changes from standard and it runs a standard turbo. Ohh, it has standard injectors as well. :jk:

That means up to around 4,000 rpm it's gunna gets its ass kicked by a basically standard R33 GTST. :throwup:

Both power graphs are on DD's in Shootout Mode, just in case someone is interested. :wassup:

So tangO, personally I don't think this turbo is for you. :cheers:

From what youve said a descent highflow will suit your pefect,

They can be had for cheap, usually around $1500

And can be flowed anywhere upto about 400-450hp

Main advantage of highflowing is cost and easy of installing.. It goes on the same way it came off, no fabrications etc .. almost anyone can do it

You get the turbo back 100% brand new, every moving part is replaced and the turbo is even all shiny again :cheers:

Steve: Can u get a GT30 with an internal wastegate?

I worked it out as probably being in 3rd actually (21 kph/1000 rpm), but I shoudln't have to WORK IT OUT. It is supposed to be written on the Shootout Printout by the Shootineer. Hey Steve, isn't that a breach of the Code of Ethics? :Bang:

    • Thanks everyone for the replies and suggestions. Got the seats out (hoping I could find some existing grommets but no such luck). By tapping and measuring etc. I could figure out where I could drill through if needed. But first I borrowed an inspection camera and managed to go through factory holes in the chassis rail and could see that the captive nut was holding steady which is why it could retighten. So it was indeed a stripped section of thread, so I applied downforce by levering the bolt head with a screwdriver and went slowly back and forth until it came out. Camera helped a lot cos I could monitor that the captive nut was holding tight. Now I just have one very seized main subframe nut to tackle 😅
    • BOVs do have a purpose, if you ever log pressure before and after the throttle body, you will see a spike pre throttle on lift off from a WOT condition. Enough to bend throttle blades / damage e-throttle motors or simple assist in blowing off cooler pipes. FWIW, the above on really applies to those running at least 2 bar of boost. OP shouldn't have an issue, on the other hand, here are some videos of my shit box over a decade ago with some succulent dose with the airbox on and off. That shit box is unrecognisable these days 🫠    
    • I've tried all different combinations of BOVs/ no BOV and stock bypass valves over the years, on gear changes the stock bypass valve seems to get the car back on boost quicker because in part the turbos wheel speed isn't being slowed down by reversion, although they have issues holding boost much over the stock setting. Most aftermarket BOVs you can adjust the spring, tighter will make it open later and close sooner, but in my experience it'll cause a bit of flutter at low load/rpm anyway. I've also got some input into this whole no bov causing turbo wear, never had an issue on any on my turbos HOWEVER, I got my R33 GTST with 200k kms on it, with from what I can see still has the original turbo, no lateral shaft play but has about 4-5mm of play in and out which to me seems like a worn thrust bearing from years (100-150k kms?) of turbo flutter running no bov, so maybe there is some truth to it in the long run. But that'll never stop me loving the Stutututu while I have the car.   OP just wants to know if he can run a atmo vented BOV with no major issues and the answer is YES, plenty of people do it, there's no harm in installing it and seeing how it runs before spending $$$ on an aftermarket ecu, last time I bought a Nistune it was $2400 for install and a tune , unsure of todays prices but you get me. Crazy money to spend just to fix the minor inconvenience of stalling that can be overcome by letting the revs come down to near idle before putting the clutch in or a little bit of throttle to avoid it. You're better off leaving the ecu and tune for after a bigger turbo/injectors have been installed to take full advantage of the tune and get your moneys worth.   Let OP have his Whoosh sound without trying to break his bank haha
    • I see you missed the rest of the conversation where they have benefits, but nothing to do with avoiding breaking turbos, which is what the aftermarket BOV made all the fan boys, tuners, and modders believe was the only purpose for them...
    • But they do so for the other reasons to have a compressor bypass. It's in the name.
