I currently have a 93 touring with intake , exhaust . I will be ordering a power fc ,fmic, dp, mp. At what point do i need to upgrade the fuel pump/injectors. Is the stock fuel sufficient??

 

you should probably look into a new pump...jason has some nice ones pretty cheap

 

That's a lot of stuff to install all at once. I don't recommend putting it all on at the same time. If you look at my sig, you'll see I have similar power mods to what you'll have on your FD.

To answer your question, *yes* you need fuel mods. A fuel pump (nippondenso, supra tt) and bigger secondaries (1200-1300cc). These will work fine with the power fc. You might be able to get way with it in the short term, but I wouldn't think for very long.

At the least, I would not install the midpipe (leave the main cat on) until you've upgraded the fuel pump and injectors, and (most importantly) had the car extensively dyno tuned with a wideband o2 sensor and datalogit. Be careful...you're getting into the kind of situation where the motor can blow sky high if everything isn't done correctly. Not trying to scare you...just trying to save you from going through some of the bad stuff I had to deal with (such as cracking 5 of the 6 apex seals)...
