i have a few questions i am going to have a turboll on the road with a new stock turbo and i will be putting a 3inch down pipe and straight pipe all the way back to the mufflers allowing great flow i just purchest a fuel cut system and will be installing do you feel any other mods are needed to pervent damage to my motor i am a newbie at this so i need feedback

what year turboII? even with the FCD if you have open exhaust and intake...it might be BOOM before long...



do you have a boost gauge? that might be a good judge and starting point as to what mods you can do...

As Erik mention, get a good reliable aftermarket Boost gauge. Is the turbo still off the car? If it is an s4(87-88) T2, you should port the wastegate. You should atleast get a bigger fuel pump, like a walrbo...

It all depends on your boost. If you can keep it <10 with a walbro/fcd you will be fine, and yes its a 255lph...

without cats.. you can delete all the emission related items as well...

air pump and acv and appropriate piping and hoses..

i temporarily removed the bac .. but the idle was very rough..

stalled a great deal even after warm up... eventually reinstalled it..

youll need a dual alternator pulley for the water pump also..

currently runnin rb full exhaust with just fcd..been light on the throttle

till i can strengthen the fuel system...

as insurance...ive replaced the charcoal cannister and fuel filter..

in anticipation of the upcoming fuel pump and injector upgrades...
