k20 k24 BONE STOCK will give you what your looking for.. But thats running you $5000+
If anything else try a BUILT LSV, BUILT GSR, or BUILT H22 out of a Prelude . But theres no way your going to hit the 200 mark with out a nice budget... a B20 would give you the torque but not the HP..
If not just get a simple B serious swap and boost it on a simple 7PSI and make it a daily ..
If not the only way to make 200HP+ is by SERIOUSLY building a block and head with add ons or go K
