Hey guys I have a completely stock 89 turbo I am adding the racing beat complete exhaust system I know you need the fuel cut controller and also a new fuel pump but what else does anyone recommend when i add that im a little worried about running to lean or rich on my air fuel mixture. I would like to add everything at once so i run the least risk of hurting my car.

 

an Air-Fuel ratio gauge.

 

i wouldnt recommend a cheap air fuel meter to anyone...however if all you are trying to figure out is.. "ooh poop im too lean" that should serve to be some warning but with fuel pump and fcd you should be fine. that meter will most always say you are rich with a rotary.

 

a piggyback fuel controler wouldnt be a bad idea. also a rising rate FPR would work well

 

port the wastegate

get a good aftermerket boost gauge
