An acquaintance asked me on Friday to look around for a kit or DIY
water injection. He's not too good on the web so I said I'd have a look
when time permitted

Time's not really permitting and, not being a car person, don't know
what would be a quality result anyway without probably going into
the whole turbo/performance/opinion debate

Can anyone suggest something good/cheap/easy (all 3 would be super).
Methods or links appreciated

He mentioned some local unit for NZ$700 and didn't want to pay that
much. Would rather DIY if possible

TIA
