Extreme PSI Precision T & E SCM50 turbo questions

[Russell]

Hello all,

I am going to be buying the Precision T & E SCM50 turbo from extreme psi this week, and was wondering what turbine sizes, and if the exhaust cutout should be ther, etc.. to go with

--ill be going with the .63 A/R
--Turbine Wheel im unsure of 76 wheel trim or 69 wheel trim, whats the difference which one is stage 2? stage 3? stage 4? stage 5?
--uncut or cut exhaust housing, i want to run 15 psi pump gas on the street or 20psi pump gas at the track, what is the difference between the 2
--ill be going with the heavy duty external gate
--ill be going with the install kit
and last but not least,
-- what way do i tell them to weld on the 90 degree intercooler elbow? left or right? (im guessing it should look like the t-25, facing left?)

thanks alot,
any other information on this turbo would be great, ive searched the fourms and read all i can about it,,, is there anyting else that i should know,, i have considered the agp setup, or RNR setup,, but i dont see the point just for an external wastegate, or am i wrong
cheers

You have a lot of stuff to do before buying a larger turbo.

You would be lucky to run 12 psi on that turbo as you are now.

FYI, you don't have a choice of A/R on the turbine housing.

well on the page it gives me the option of slecting the A/R size
is that incorrect? do i just get a standard .48 or standard .63?


also
what is the difference between the turbine wheel sizes 69 or 76 wheel trim?
which one is stage 3? or standard?

any info would be great,
thanks
