I've seen ghetto fuel support where the return is crimped with vise grips. Works....but not for long.

Upgrade to a bigger fuel pump for sure. Walbro makes a couple units for our cars. 190 and 255 high pressure. Yes, they're loud but they work. You can also use an accel inline or the like. You can be cheap and grab a gst/x fuel pump from a junkyard. You should be fine but mechanical fuel management may still ask for more fuel than that pump can supply and cause problems.

Fuel system upgrade is a must. I get flammed on some sites about fmu's but they work and are fine for what you're wanting to do. Personally, i'd go with an sfmu just so you dont have to get one later. You'll want more boost. You can get dsm 450's with a resistor pack for around $30-50 on most car forums and egay.
