any suggestions on what should be down to my 03 oz lancer 4g94 before a turbo. i have a cold air intake and exhaust.

to get full performance of the turbo your using, much needs to be done bigger fuel pump adjustable pressure regulator bigger injectors out an evo or some thing adaptable you need to tap into the thermostat housing for coolant return line and feed line you also need a T valve for the oil sending unit to give the turbo oil and tap into the oil pan for oil return it might b a good idea for a oil cooler as well and maybe better cooling fans such as a flex fan set up obviously an intercooler all the piping you can get an adapter for the stock manifold to a t25 turbo or any other they sell them on ebay and most of all time and patience and room in the egine Ive done turbo setups for less than 600 by going to junk yards alot of welding cheap ebay parts hahaha if you relly want to do it read up and do some window shopping I would suggest ebay If your not looking to make a power junkie
