IMO, it isn't worth it. You'd be better off getting a GSR, or Turboing an LS or even the b20. The b20's sleeves are weak when it comes to turboing them, you would need to resleeve. If your looking for an all motor. The crvtec is a good track candidate, but not daily driver....same with the lsvtec. The b20 block is strong enough to withstand all motor (depending on copmpression) but shouldn't be overlooked just because it can take the abuse, it just wont take it for long.
The was a site, crvtec.com/b20vtec.com or something like that. Gives you a good explanation of how to do everything. If you have problems finding it search for LSvtec. Technically the b20 block is just an LS block with .2 L more displacement.
Since your goal is only 200 hp, you'd be good with an LS with a low boost set up. It will probably even bring you past 200 with it. I never dynoed my old one but my friends gtech thing estimated hp at around 230 or something like that on 8 lbs on a T3.
