Important tip when installing BB turbo's

[R31 POWER]

That pic looks like my oil thingy in the GT2535 but you can't see the smaller hole in the pic.

Hey People,

I just gave gcg a call asking them if i need to add a restrictor to a gt2530 turbo on an r32 and they reakon u dont???

Are they full of it, what do u reakon?

My pair of HKS 2530s each needed a restrictor however these were older units, not the GT series like yours - GCGs advice supports what the other guys have said above ie you do not need a restrictor on the GT series.

George that picture that you posted is just the way that the fittings seal themselves properly.

At the top left of this chart you wil see a cutsection pic of the GT series showing quite clearly some very fine passages leading to bearings...

As i said before

That isnt the restrictor.  As i said, its internal.

you cant see it unless you pull the cartridge apart and look at the bearing casing

you dont need a restrictor at all
