do all ihi rhb5 turbos have the same flanges? also would a downpipe for an rhb5 turbo fit any rhb5 turbo? thanks.

 

No, you need to search around for a little bit to find both... There are two RHB5 flanges, one is a square, 4 bolt flange and I think the other is a 5 bolt odd looking one, I can't remember. The downpipes are different as well.

 

Sadly, I think there is also a 3 bolt flange...those are the cheap ones at the junker

 

IHI RHB5 VJ11 has a square 4 bolt inlet.

 

also the RHB5 VJ14 has the 4 bolt square inlet and the exhaust outlet on it is the 5 bolt one with the internal wastegate
