SR20DET swap

I'm doing an SR swap in my S13 240SX. What mods should I do to get the most HP on the stock turbo and internals? So far I've got upgraded exahust manifold, 3" turbo elbow, 3" downpipe, test pipe, 3" exahust, Wideband 02 sensor, Super AFC II, AVCR, I'm getting a Front Mount IC. The engine came with these injectors with a black colored plug. I'm guessing they are 550cc injectors. The stock SR injectors have purple plugs and are 370cc. So besides that I'm not sure what elese to do as far as gaining HP? I'll get a bigger turbo early next year. Possibly a GT28R. What else can I do in the meantime?

port and polish exhaust ports, Bigger MAF, balance and blueprint, lighter flywheel (you don't have a slushbox do you?), heavier clutch pack, intercooler, oh yeah and a flowmatch on the injectors.

Yeah I got a bigger MAF sensor. No slushbox. It's a 5 speed manual.

Sounds good to me. Cams would be nice from Tomei or Toda.
