I bought a '93 touring a couple of weeks ago. It's only got what's listed in the signature below, the street port and the downpipe. People have told me that if I do anything else to it, I need to upgrade the fuel system. exactly WHAT needs to be done the the fuel system? Also, from the downpipe back, what needs to be done to let the engine 'breathe?' I've got an intake at home that came with the car, but I was afraid to put it on if the fuel system wouldn't support another upgrade. I'm just learning about these cars, and I want to do things right. Keep in mind in your replies, this IS my daily driver. I don't want a bunch of mods that could potentially cause any problems. I'd appreciate any of your help. -BN

The first thing you need to add is a Boost Gauge if you do not already have one. A boost gauge will be invaluable if/when problems arise in the car.

 

Think of the mods as a kids see saw

Down pipe increases boost - Need more fuel (stock ecu has fuel cut) ...get boost gauge

Freeflow intake - need freeflow exuast

more air going through the turbos - better intercooler

racing spark plugs - racing spark plug wires

front air damn - rear spoiler

Quick ecceloration - quick braking
