35r vs 37r
 

What exacyly is the difference between the GT35R and the GT37R?

Power and outlet size

There different size turbos.....

What exactly do you want to know?

Isn't the housing the same?

bump for a good question.

spool...power...

What exactly do you need to build in your engine to run the 35R? I heard Forged pistons and rod, can someone get more specific?

Doesn't depend on the turbo, depends on power you're making with it

generally, to sum it up
the 37R can produce more power as compared to 35R
however
the 35R is not as laggy as the 37R
it spool faster

dont be lazy
37R is more on high end power
35R is mid-high end power
