well sounds liek you do have a good start.....Yeah the TB w/ some P&P would give you better air flow and a little more HP.
Yes they do make a cam gear for your car but for a SOHC you are better off to wait and get a camshaft and put that in w/ the Cam Gear and you will feel and get a whole hell of alot more from the 2 together.
Only other thing is that yu stated you are running the Denso Plugs..Why? They are really more for running NOS and what not on a ride...Had you thought of going w/ NGK Plugs? Just asking....
