i keep changing the setup so i dont know which turbo to go with.

I have a gsr, built with 9:1 com cp pistons, and eagle h beams...stock sleeves, and i need to figure out a turbo to get me atlest 350whp
which one to go with?

Garrett T3/TO4E 60 Trim Turbocharger
.63 a/r or
.82 A/R or

Garrett T3/TO4E 57 Trim Turbocharger
.63 a/r or
.48 A/R

 

i wanted an sc61 but they are a bit expensive, which one of these is closest to that?

i think the 60trim 63a/r will be the best bet?

?

 

I would just go ahead a spend the extra money and get the SC 61. You already have a built bottom end so why waste money, see what she can do with a good turbo.

 

this is if i go with the sc61 i cant get anything better than a log manifold....cash is tight after the buildup

 

60 trim defntly at the very least. for 350 you are looking at atleast 12-16 psi depending on mani, down pipe and the efficiency of the motor.

My st up has the T3/60-1 63AR this should get me to 330 stock motor at about 10psi 3 dp and tubular mani.

 

hmmmm, so whats my best bet if i want a new turbo for about 600?

 

man you should make plenty of power on a log style manifold, just save a little more money and get a sc61 or get a gt30r. Do it once instead of 3 or 4 different times and waste money and time. pm arturbo for prices he is very helpful...
