What Size Jic Water Fittings For Vg30det Turbo?

[floody]

I just want to slot together some water fittings for my VG30DET turbo (late model OP6 one) ; I'm fitting it to an early HR31 redtop RB20DET which runs smaller banjos and bolts compared to the silvertop and RB25, as such I need to adapt water lines to suit. Have had no luck getting R32 or R33 water lines so am going to adapt what is there.

Just wondering which size fitting is the go, JIC -6 or JIC -8?

Plan to run the JIC fittings, with barbed end to JIC swivels, then hi temp water hose clamped to cut-down original water lines. Hoseclamps and away.

Plan sound fine?

i run -6 line on my turbo, -8 may be a bit much...
