Default Arashi GRF TD06SL2 20G Ball bearing

I recently upgraded to this turbo so I thought I would share some of my findings.

Stock Car: 2018 STi AU Spec 220WHP
Stage 2: Processwest intake, RCM EL headers, Catted down pipe, 3 port - 273WHP
Current: Arashi TD06SL 20G BB, ID1000's, Turbosmart FPR, DW65C - 321WHP @ 20PSI
All power runs on same dyno.

This turbo spools like the stock car but laggy compared to stage 2 setup about 500rpm slower to make same boost but makes power all the way to the redline.
The only issue that I have had is slight boost creep that could be result of the wastegate preload being set incorrectly out the factory, will play around with it and see what happens otherwise I will port the wastegate port.

Hope this helps you

Found this thread, it would be great if you can post a dyno and tell us how's the Arashi holding up.
