I think the 045 bit relates to the K03. The "S" bit doesn't actually exist. The S turbos are K03-052/053/058.
you fitted your new turbo yet ivor??
Yes, mate!!
(I also got the sports cat fitted at the same time) although it's leaking coolant from the side of the turbo (still).
It's already been back once, so it's going back again on Thursday, & will hopefully get sorted this time. (Along with a new R32 dogbone
).
I've also had the stage 2 custom code put on so it runs like a dream, now. 
so what is the out put on that ivor i was think of do it put changed my mind does it pull well.
Yeah, it pulls like a horny, fit blonde in a nightclub!!
Don't know the exact output, ATM, but it should be between 220-230bhp (hopefully
).
i mite b changing my mind again so all u hav do is ko3s and high flo cat plus custom code remap,
where did u it the dsg air intake box i hav the cai intake and scared of gettin water in my engine like ash has.
You don't need a high flow cat - I'm just greedy when it comes to power gains!!!

However, you will need a K03 "S" turbo inlet pipe (Forge, SMS or even OE AUM T.I.P.), though. And the remap, of course.
