Need help deciding on turbo for 1ggte.

[Blair]

hey guys, I'm not too great with turbo sizings and stuff like that.

Anyway I am looking at a gt3076r .82 off a guy I know.

Someone is using the same spec turbo on a 1ggte in his corolla and mentioned it was hitting full boost at or around 4000rpm.

Now I have found a gt3076r .63

Just wondering if it would make much difference lag wise?

Thanks,
Blair.

How much power you want?

[Blair]

Would like 250ish if I can.

Any idea roughly how much sooner it would be hitting full boost over the .82 ?

As spoken by mr 1ggte, kyle aka 6boost

Turbo sizing..... WIth a turbo intake manifold fitted with an XF throttle body, and the factory butterflies removed, you can expect the following output and spool from various turbo's. Please keep in mind this is +/- 200rpm or so, as exhaust manifold design and camshafts play a role.

2871R garrett or KKR 380 = 230rwkw on 16-18psi.............3500rpm full boost
3071R garrett or KKR 430 = 250-260rwkw on 19-21psi.......4000rpm full boost
3076R garrett or KKR480 260-280rwkw on 21-23psi...........4300rpm full boost
3082R garrett or KKR520 280-300rwkw on 21-23psi ..........4800rpm full boost
3582R garrett 300-340rwkw on 23-30psi........................... 5300rpm full boost
T66/TO4Z 350-440rwkw,.......................................... ....... 6000rpm full boost

I had a t04e with .63 rear hosing and didnt hit full boost till 5500rpm, i guess its a bit to late now
