Right, Had no luck in general chat so I'll try here. I've been looking throught the receipts for my car and there's a receipt for a Stage 1 hybrid turbo at the same time as the last rebuild (18 months ago) How can I check if this is actually fitted?

I had a look at my Turbo and it looks diferent to my mates, his (should be std) is rounded on both sides and has "AIREASERCH" written on the back. Mine is flat on the back side, but on the front I noticed it says "A/R .42 GARRETT".

What markings should I be looking for and what do they mean????

Cheers

Lee
