My friend in sc can get a garrett .63 trim for 550 shipped but someone on ht has the precision sc50 for 595 shipped........Which to choose? arent they the same thing?

.63 isn't trim, it's the A/R ratio of the housing to wheel. Did you mean 60-trim vs. 50-trim?

 

my bad its this then :

GARRETT T3/T04E 57 TRIM W/ .63 A/R TURBINE

 

a 57 trim is slightly bigger, where as the SC50 is a 50 trim, its up to you which turbo you want to choose. they are built practically the same.

 

all depends on what motor your putting it on and also what kind of powerband you want

 

the sc34 in precision line is identical to that turbo

 

The SC34 has a 57 trim wheel (56mm diameter, 2.320" inducer/2.950" exducer) on the compressor side and either a 69 or 76 trim wheel on the turbine side, so there are actually two different versions of the 57 trim.

Also, don't get too hung up on buying a turbo based on the trim size. Compressor trim is a mathematical calculation, which is Inducer Diameter squared divided by Exducer squared X 100. The point is, there's more than one different way to go thru this equation to come up with a 57 trim. Example: 3+3 = 6, 4+2=6, 5+1=6, etc. You can also have different sized wheels with the same trim.

Hope that sheds some light.
