BNR ST71

The BNR ST71 turbocharger upgrade is intended for cars with auxiliary fuel systems!  This turbo is good for up to around 500 WHP.   This upgrade takes a little longer to spool over the ST67 (300 RPM) but nets around 100 more peak HP when maxed out.  If you anticipate aux fuel system and/or a forged internal engine this turbo would be the best option!

This is what you get when you purchase the ST71!
