Rb20 - Disco Potato'd (gt2860rs)

[Sarumatix]

I have one of these with a 6 bolt rear flange mounting to go on an RB20. I did not however realise that the intake flange is 75mm where as the factory setup for RB20 is only 60mm. What is the common approach to getting around this?

custom pipe / rubber and hoseclamps?

Ya I guess this is probably the only solution

You could just use a 70-60mm reducer, couldn't you? Let us know how the potato goes on a RB20, I know it's the tits on an SR20. what AR are you using?

[Sarumatix]

Having a look at the pipework, it's more like 70mm with a 60mm reducer on the turbo. So we going the fabrication option.

AR 60. and yeah i'm surprised to see so few on RB20s most people go straight for bigger or rebuilt option.
