The USDM IX turbo does not have the Ti/al turbine wheel that can be found on various versions of JDM IX's, and they are not always paired with the Mag compressor so they would spool quicker and be reliable running higher than stock boost. I'm not sure how easy or expensive it would be to source one though. There is also a TD05HRA-155G6C-10.5T used on the JDM IX MR. It has the Ti/Al turbine with a slightly smaller 15.5g compressor wheel for quicker spool, but a small trade off in top end. I think for ultimate spool a BBK light upgrade with a JDM Ti/AL turbine would be awesome.

 

we can certainly help!

we have built almost 15 BBK's this week, so people seem pretty happy hee he!
