What's The Likely Max Boost My Tuners Will Use On Hks Gtss Turbos?

[boobeedoobee]

Hey my car has the usual mods and is 270 rwkw on e85 just purchased a set of hks gtss turbos and was wondering what would be the max boost I should push these too on an my unopened rb26? Btw it's in a 32 gtr

[Piggaz]

From the general results, anything more than 24 psi they have nothing left. Boost wise, they will fall off after 7000-7500 RPMish.

[levinboy]

Keep them at 21-22 should be sweet and like sir pigggggy said no need to rev them past 7500.

[Griffin]

What power do they generally make with e85 on 22 psi?

[Blackkers]

Should make more than 350rwkw

What power do they generally make with e85 on 22 psi?

It really depends on supporting mods, but on a stock motor with 22psi should be anywhere from 300-350rwkw

[boobeedoobee]

Damn so I might see a gain of an extra 80 kw at the rear wheels from these turbos? I'm also putting a set of midori dumps on too.

[XKLABA]

The midoris are a good idea to, the 32 has the worst dump pipes of the three and there are big gains in both response and power from changing them, couple that with good front pipe 3.5 cat and catback and you will have more then enough exhaust flow for the GT-SSs, exhausts are one of those bigger IS better mods

[levinboy]

Well I make 350kw on 21-22psi on 98 but built motor

All depends on how much the engine can take safely

[sinistaGTR]

I made 330kw on 21ps 98... I wouldnt expect any more than 350-360 max on GTSS, they just cant flow anymore

[boobeedoobee]

Sweet Yeh I have all the supporting mods and a full exhaust, e85 with 1000cc injectors .. car is sitting on 270rwkw at the moment i will post the gains I get once I install the turbos and dumps. Forgot to mention it is an unopened rb26 though but it's very healthy.

Unopened 26 will be fine for a fair while with 24psi and that power on E85.
