T3/t4 differences really need to know

What can I push my HRC S20G turbo to?

Pump and C-16 Race gas.

I've done 20psi - on 92 oct.... and did 322whp.
I've done 24psi on C-16 and did 363whp

You've seen my list of mods.
HRC S20G
Greddy Lg FMIC
Complete I/C piping
Blitz Bov
Injen intake w/K&N
RC550 inj
Walboro 255 Fuel pump
magnacore 8.5mm spark plug wires
NGK plugs - one degree colder
HKS 264-272 Cams
A.R.P. head Studs
SAFC
3" downpipe - custom
3" Exhaust - thermal
Ported Exhaust Manifold
Aftermarket 02 houseing

I guess another question is can I run more then 24psi on C-16 with out breaking anything?

We have a big event coming up Domestic vs. Import.
And I was thinking about dynoing at 26psi. on C-16

My EGT's were at 1500 when I did 24psi. on C-16 and
363whp/355ft lbs torque. on the dyno.

I'd hope with 25-26psi.. I'd get closer to 380-400whp.
which is where I'd like to be for this event.

.48, .63, and .82 are T3 housings.
.58, .70, .81...are T4 housings.
you can't really say a .58 T4 housing is between a .48 T3 housing and a .63 T3 housing...

it seems like everyone but jay dislikes the .82 T3 housing. a lot of people don't care for the .63 even. my roommate has a .48 T3 turbine housing (T04E 50 trim, stage 3) on his sr20det, lag isn't bad, top end feels good.
