As far as I'm aware the bottom end for the 1.8 20V non-turbo is
the same as that of the 150/180 20V turbo's, as with most of the 4 cylinder water cooled VW engines. The 1.8 20V
non-turbo uses pretty much the same large port head as the AGU 1.8T's,
so would be a good choice to use a big port head if you plan on fitting
a bit turbo. I assume you'll be using an aftermarket ecu such as Motech
etc for mapping?

I'm thinking of going with a uprated k04 turbo i'm looking for around the 350bhp mark so i think it'll be ok for that .ecu well i'm think it's going to be a trip down to jabba sport to get it sorted maybe a full remap will do we'll see.

Sounds good mate, will look forward to hearing how you get on.
Just to say though, you will need a much bigger turbo than a K04 to
flow enough air to make 350 flywheel horsepower, thats IHI VF34 on P20
housing teratory. The maximum possible from a K04-023 as fitted
to 210/225 engines is a reliable 280bhp (The compressor side from this
turbo is whats used in most of the 'bolt on' hybrid K04 upgrades
available for the 150/180 engines). You can change the compressor
housing for a larger item such as what HGP motorsport offer and that
may just push the car over the 300bhp barrier. Good luck anyay.

Dunno if that'll work, your ecu will be missing functions the golf turbo one has, such as MAP (if its a newer engine) and control for the N75. I honestly think it'd be easier just to sell the car and buy a new one.

EDIT: im confused now, is your car a AUM or a non turbo?!

If your car's an AUM then you are better to stick with the standard VAG
management then and just get it mapped by Jabba or the like. Yes
you will be able to use your existing hi-flow cat and downpipe, the
downpipe will just need to be modded slightly to fit onto the the
supplied 3' pipe from the turbo, but that won't be a problem.

Out of interest, why are you wanting to get another bottom end
etc. Are you planning on building the engine in the garage and
then put it in your car in one go, reducing time off the road?

Fair enough, look forward to hearing how you get on. Don't know if
you've looked already but you can normally get rods, pistons etc much
cheaper from the States. If your not planning on increasing the
capacity then for the pistons, I would personally just get a set of
pistons from a 210/225 TT/S3 engine as they are essentually Mahle
pistons, so will be good for an easy 400bhp, you could get them ceramic
coated for extra piece of mind and would save some money over regular
forged pistons. The rods and valves tend to be the week points in these
engines anyway.

Got me thinking now?... would that HGP item work with some of the 04 hybrids that are floating about at the mo? ie AM04, JBS04 and BB04?
