ok guys i need some input on what size of turbo to go with? im looking to get a treadstone turbo kit here pretty fast( along with one of their TR6 intercoolers, i dont like the thought of that verticle flow one, nor removing the front bumper brace) and so i need to decide on a turbo for the kit.

this is the setup on the engine:
JE pistons/eagle rods,crower stg2 turbo cams springs & retainers,adj. cam gears, mild p/p,3 way valve job, 60mm jeep TB, 2.5DP, Greddy evo2 turbo exhaust, 450cc inj& SFMU/SAFC for tuning.

im hoping to run around 10-12psi to start with and in the future when im comfortable with it 15psi. so i'd like a turbo that will spool right around when the cams start to build power, but have enough headroom to support the 15psi.

any suggestions?

thanks to the members of 2gnt.com, without it id be in the dark.

If it were me, I would paw through the choices at www.atpturbo.com. Treadstone manifold...so you will be looking for non-wastegated turbos with T3 inlets. There are a lot of options, depending on your budget. To help me choose, I would read reviews and look at dyno sheets for popular 2.0l cars like the EVO. They don't translate into a boosted 420A directly, but it is about as close as you will get.

see, according to treadstone i have my pick of any hybrid turbo off the site ( http://www.treadstoneperformance.com/view.phtml?f_cat=Turbo+Chargers%3A+T3%2FT4 )

so im thinking T3/T4E 60 trim with an a/r of .63... or is this too much? when will i see boost with this turbo?

bump anyone? id like to figure this out and hear some input from people who have experimented with different turbos.

a 60trim with a A/R of .63 on the turbine will build boost around 3000rpm and full boost 15psi i would expect around 4000-4500.

60 trim full boost at 4600 around 14-16psi, like Terry said. I used a 60 trim before I got my new turbo, and it was nice. its a good turbo, stick with that choice IMO.
