any have specs on borg warner s475 and s 480 t4 a/r wheel sizes

 

...what do you want to know?

 

just wanted to compare to my magnum t 76 -96 a/r

 

This website has all the turbos and maps, BorgWarner Turbo S400SX4-80 S480 S380 80mm TURBO (S400) PN: 177287

AR on compressor outlets arent really important.

 

Tim for your set up I would do the 80/83 1.10.
You'll need a different downpipe.

Keep in mind you'll loose some down low.(gears fix this)
But pick up a huge amount hp up top.

Hit me up when you ready to switch up.
