Hi, PWRXers,

Recently (particularly last week or so), I notice there is metal vibrating noise come from the engine bay directly in front of me. I thought its my CAI bracket coming loose, but it's not. It only happens when i accelerate hard regardless what rpm the engine is. PLUS, in last month I have added a litre of Redline 10W40 to keep the oil level above minimum!!!. As Im doing my exams, I havent got time to physically check the turbo. Do you guys think my turbo has shaft play now?

If i need a new turbo, I want more response rather than power. How about the following list sounds like:
Kendo dynamic TD05H 20G (billet wheel, 7cm hot side) tuned to 19PSI?
Kendo UEL header
Bosch high impedance 1000CC injector (better idle?)
DEI heat wrap (dont want big money on ceramic coating as Im gonna seal the under tray beeter to stop rain water) + heat spray
Redline 5W30 for winter, 10W40 for summer
SBC three port boost controller
BeeR rev limiter to disable fuel cut (thought rev cut is safer than fuel cut)

Thanks in advance.
