Help with Turbo and Wastegatefor my Skyline R33 GTS

[Performance Werkz]

Im looking for a replacement or an upgrade for my turbo.

Think i blew mine. Rattling sound coming from the turbo itself.

Boost Meter still reading boost but very little.

Wondering if its from the wastegate or the turbo itself..

Anyway...I might be getting a HKS 2540 BB Turbo and i need a wastegate.

What wastegate should i get? a 48mm?

What Injectors and How do i mount the turbo upwards? Do i need to change my manifold to a top mount?

thanks!

The HKS 2540 has an internal gate.

Do i stll need an external?

Whats the purpose of external?

Is it better to have an external?

Thanks!

for that turbo you do not need on because like the stock it already has its own on it,

and external are for bigger turbo apps mainley like to4's etc ,and for the rest the hks 2540 is a direct replacement for the stock. hope this helps
