A better mass air sensor might be good, I'd probably stay with a 65mm tb. The trick flow intakes are supposed to be good, some port work would definitely help with the intake/1.7 rockers. I got a Standard Abrasives porting kit from Jeg's for around $40 I think. Check out their site standardabrasives.com, you'll get a pretty good idea on what to do if you don't know already, I'd also go to a sears or hardware store and get a metal grinding bit (the cylinder shape ones, about 1" long, 1/2 thick or cone shaped), their good for grinding large amounts quick, the sandpaper ones clog up after a while and take too long. Anyway, match up the ports and clean them up, especially the exhaust, I ground off the bumps and smoothed/polished them. I'd think you'd be well into the 13's.
