Hx40 Upgrade

[Lucas]

Hello all,

I have a 2000 C3500 and I'm waiting to do the hx40 swap. I've done a good bite of research on it but can't find any info on the difference between T3 and T4 flange. How do I know which I need. Also any recommendations on what turbo to buy.

Thanks

The 6.5 td has a single T-3 flange the Holset or CKO full sized HX40 comes in either a T-3 or T-4 or bigger with and without internal wast-gate.
