I have a 93 rx-7 with a downpipe and a racing beat exhasut. I also have a wolf 3d engine management system, but I haven't installed it yet...What basic modifications should I install to get it to that next level of speed? I was thinking BNR stage 2 turbos, front mount intercooler, and air intake, but I wanted to get some opinions first...

I think before you go to the next level of speed you should do all of the suggested reliability mods (vac lines, fan mod, etc). Do a search on this site for reliability mods and you'll get that info. I don't know the Wolf Engine Management system, but with the front mount, intake you will also need to do fuel pump.

Reliability mods are a must. Instead of doing upgraded twins, I'd go with a single. And you'll need a better fuel system.

Why would I want to go with a single turbo...won't i sacrifice a lot of low end power?

I'm definitely NOT an authority, but as another owner of a relatively stock 3rd gen. I agree with Sensenv, do reliability modifications first. Mahjik gave you a link that was a BIG help to me when I first got mine.
Regarding the Twin vs Single question, IMHO, seems to me there are two distinct schools of thought here. Yes, with single you will give up low end (low rpm) power, but gain simplicity and the loss of about 40 miles of small vacuum hose used on twins. The intended uses of the car, i.e. track vs street, personal tastes and mechanical skills, would also have alot to do with it.
