1) get the cams
2) get the torque converter (with optimal setting to pick up the most of the cams' power when I do get them)
3) forget performance and get some wheels.

I would recommend getting a 3,300rpm stall converter with a pretty good sized transmission cooler. In my B13 GA that I had running almost 90% of the bolt-ons (excluding Pulley, Cams, ECU) I had a 3,200 stall converter and for a while (22degrees timing.. too high), I was beating stock GT mustangs till 80mph. My 0-60 mph was 8.2 and my 1/8 mile was 11.2 sec (down to 15degrees timing). If I had a 3,300 stall converter, cams, ecu, I'd run about a 10.6-10.75 in the 1/8th. A stock 91-94 SE-R does 0-60mph in 8.2 sec. (spec taken from several car websites)
There are two places that I recommend for converters: Level 10 and Edge Racing Converters (mild street edge converter). I'd recommend Level 10 if you use the group deal to get the converter and maybe a tranny kit or the full racing tranny (holds up to 600hp, 500tq / 1 yr warranty). If you were just getting the converter, I'd recommend Edge Racing Converters. There is a guy there named Andre that can help you. Tell him I sent you.
One more option: You can get a converter designed with Andre for either Torque Multiplication (lower rpm start) or for Stall (higher rpm start). The torque multiplication may better in some cases. I've heard that a very efficient torque multiplied converter can run a 4:1 tq multiplication. So, let's say we look at the stock dyno, @ 2,000 rpm it produces close to 80lbs of torque... it can be multiplied to 4x times that - 320lb. tq! 320lb of tq right off the line! Another advantage to the torque multiplication (low stall), it is more efficient and does not produce anywhere near as much as a high stall does. The converter is best when it works with the powerband of the motor. A good converter gives good torque multiplication at an rpm that is right below the power curve of the engine to allow you to launch quickly without burning up the transmission.
In conclusion, there are factors that you should communicate with Andre (Andre gets more technical on converter design than other people I have talked to). These factors consist of the following: first gear ratio, final drive ratio, tire diameter, vehicle weight, vehicle brake system, engine power curve, and engine size. Send him the pictures of the dyno's with the mods you plan to do.
Good luck and give Andre a call!
