I have a Wiseco/Eagle built B16 w/ a fully built skunk2 head aiming for 300-350whp DD on 91 octane, s300 ecu, 8200-8400 rev limit.

I am running a Neukin topmount manifold.
I wanted to run a GT3076R 0.82 A/R but they run for about $1,200-1,400 w/ shipping to Canada BNIB, but I can get a BNIB Precision 5557B 0,82 A/R for $790, which is identicle to a GT3071R.

I CANNOT find on Youtube any 5557B videos. How does the spool sound on this turbo compare to the GT3076R?
ALSO, a used Precision SC6262R is in the equation for $800. Feedback on this turbo would be appreciated as well.

I am looking for more so, spool sound comparisons to the GT3076R. It has a BADASS spool sound my buddy had one on his b16 setup on 9psi and it HOWLED ridiculously loud.

 

From what I read they spool the same but the billet make more power on top.

 

That's a good option for your power goal. Go with the 5857 if you want room to grow in the future... You're built to handle it

 

if youre looking for quick spool the 5557 should be quicker than a 3076, however your setup is wrong for your overall goal.

The top mount is overkill, and will only serve to hurt your spool time and response, and overall there really isnt a need for it.

I highly suggest getting rid of that top mount in favor of a shorty or ramhorn. The mini ram (shorty) will help with throttle response and spool time.
