here you go. DIRTY 74mm borg warner bush bearing cat diesel turbo vs GT4088R same boost as you can see "GT" isnt the be all end all of turbos.....
AND A SIZE COMPARISON for these two turbos. "GT" vs shwitzer borg warner. AND THE BORG WARNER IS A SOLIT 10MM BIGGER IN WHEELS ON BOTH SIDES, jet still has the same responce.
not having a go at you, just saying old, tried and poven wins every time.
