As with all JDM engines, sometimes people mod them over there before they come HERE.
Usually most people remove that stuff before they sell in the USA, but apparently these people decided to sell it with the turbo.
Ive gotten GSRs with aftermarket intake manifolds, headers, cams, springs, ret, etc.
The B16 Tranny i bought from Hmotorsonline.com had a ATS 3rd, 4th gear an i wasnt charged extra for it, just came with it.
Johnzm got a b16 swap from Hmotorsonline that came with a Toda Flywheel.
SOmetimes you get lucky
