i am making 380 whp off of a t3/t4oe 60 trim turbo w/ a .63ar t31 turbine section..
but the power band is awsome

see here run done at 18psi:


i would like to have a very similar power band but with more whp of course..
goal would be around 450 whp with good strong torque like 375wtq..on pump gas

i don't think my 60 trim will take me there..so i have been looking through different options and i really like the t3/t61 turbo with a .63ar stage 5 turbine

experts??? or

have you ever thought about going with a bigger turbine housing. I know the T3/T4 60 trim can do 450whp. going with a bigger turbine housing your going to get a little bit more lag but it a cheaper alternative. just a throught.

Justin Olson

Go with a sc61 if you dont want much more lag, but more overal power capability. You could also check out a gt3767 with a t3 turbine side. These are good for over 600whp.

meaning using a .82 a/r w/ a stage 5 wheel???
also i would like to achieve this on 93 pump gas...

yeah a .82 turbine housing

now if i were to get the t3/t61 with a .63 a/r turbine housing and stage 5 exhaust wheel

how bad at the same boost levels(18psi) would my spool time be?

off 1000rpm?

anyone w/ a t3/t61 on a h22 dyno??

legendboy

Keep your turbo turn the boost up?

Here's a SC61 at 16psi...

get a holset snail:

hx35 turbine housing 12cm (apprx. .53a/r) or a 14cm housing
hx40 compressor housing (approx 71cfm/min)
trust me it will pull w/ a nice spool

graphic

that graphs not to far off from mine..
but what a.r turbine housing was it with?
the sc61 looks like it hits 16psi at 4750-5000rpm
my 60 trim hits 18psi @ 4500rpm

graphic

bump..

what trim size is the sc61 compressor wheel ??
cause if it just a little bigger than the 60 trim, does it real make sense to get it?

bump!!

Bringing it back from the dead but, what is your complete setup?

...And what turbo did you end up getting?
