do i need hahn o2 housing for hahn turbo?

[bubbaGSX]

i have s20g turbo and im about to get the hahn install kit for the turbo. hahn says i have to get their o2 housing now, is that true? or they are just doing their jobs?

i still have my stock o2 housing with n1 downpipe. if i have to get their o2 housing will i have any problem bolting it to my n1 dp?

thanks in advance!

You will need one of their 02 housing due to the discharge side of the 10cm^2 turbine housing on that turbo. Your N1 DP will fit with their 02 housing.
