I would say you can get it to around 400-500bhp without the use of a turbo an not alot of money. However most people will class nitrous as cheating which is really anal to be honest.

400-500 without a lot of money? without nitrous the most anyone has managed is around 299 bhp (as far as I know) and it was built by SBD

only suitable for competition use when you are limited to 2000cc really. theres not many other n/a 2000cc engines that will see those figures

In my eyes nitrous is not classed as Forced Induction as its doesnt force the air in. And for 1-2k you could have it near 400 instead of 12k. Dont know about anyone else but I know what Id rather do.

This is what mine is running at the moment, but i need to get the cam timing done, better manifold, take teh rev limit up to 7750 and get it remapped again, then i should be around 210ish.

Mines running 226bhp at the moment but need to lower the compression ratio so i can advance ignition timming as it's only on 20 degrees advanced at the moment, but just wanted to see what other peoples were putting out.

Nitrous is still kind of NA, the engine sucks in the nitrous, it aint forced in.
But its then letting the engine burn more air/fuel than it naturally could...

What engine spec?
For good power NA, revs and high compression is required...

more ignition and higher compression is a lot better for power. also you cant advance ignition further than MBT anyway so the lower compression wont help in any way at all!

was told to lower it to about 12.5:1 and advance timming to 28 or 30 degrees when i get it set up, need a port and polish aswell but can't afford it.

12.5:1 Compression is rather high. if you need to lower it to that what are you on now 
also ignore the 'time it to 28 degrees bla bla bla" you need to set ignition advance on a dyno with mappable management under varying loads to the point of MBT (minimum best timing) i.e the point at which you stop gaining power as you advance ignition but before you get knock.
