Quick 20v turbo Question

[Jonas K.]

OK, so I'm putting together the pieces for my 20v turbo project into the CQ. 

I've sourced the exhaust manifold, and I have a question about the turbo. 
Is it just a KKK turbo? Will any KKK turbo mate up to the EM, or are there
different hot-side bolt patterns? Will the KKK K03 from a 1.8t bolt up? 

The Intake manifold is expen$$$ive, but if the turbo fits under the 20v NA
manifold, then I don't mind using it. Will the new injectors fit in the stock
IM, or would I need to machine new seats for them? 

Also, if anyone has a set of NG or NF pistons sitting around, I'd be interested
in buying them. With or without rods. 

That's all for now, 

TIA for any advice, 
Jonas
