Can anyone help with compressor maps for HKS T51R Kai and SPL?

I have hunted hi & low but no can find.

Cheers

Goodluck! I've tried to no avail.

They should be pretty close to a Garrett GT42, other than the influence of the compressor housing itself. They share rotating components.

Very frustrating when they don't publish information. They are inviting you to buy their very expensive turbos but don't give you the info to make an informed decision on which one is best. https://www.nopistons.com/forums/pub...1047683358.gif

So don't. Buy an GT42 and enjoy the better performance from your choice of turbine housing and split runner exhaust manifold.





Plus the fistful of money saved.

If you have someone on speaking terms with HKS you can get different hotsides for the T51 series... I really like the Vband T51 stuff myself.

Do you have a Kai or SPL?
