Hmmm.
You can reach 200hp but it won't have as much torque as you would wish.

Here's a list though.
1.) exhaust header(make sure it's from a reputtable designer there's quite some physics in it), big bore throttle body w/ larger piping, K&N filter, and port match intake manifold w/ head (do not port match exhaust header!).

1 1/2.) larger valves(Stainless steel w/ undercut) intake: 1.38in, exhaust: 1.20in /or valve to port ratio of 100:75 for intake and the exhaust supposedly around 85% the size of intake valve.

2.) Work out a good Cam timing(35-75 or 40-80), advance exhaust timing 5-10deg, valve overlap( not recommended with AMM though), and valve lift(29-31%).

3.) High compression pistons(I recommend some type of Knock sensored ignition along with).

4.) Sequential fuel injection (quad throttle body route w/ valve overlap would work w/ speed/density seq injection)

But if you don't understand the mechanics, I wouldn't take my advice. Just enjoy your car how it is.
