Hi I have an built 84mm b16 std stroke Built for turbo with cp 84mm 8.8:1 pistons, eagle rods and egle std crank with a built head with stk cams. I wanna boost 15-20lbs. Hopefully 20lb but I dont know what size injetctors to get . I have some dsm 450cc will those work or whats the max boost i can run with the 450cc. Oh and what size fuel pump should i use will intank walbro 255 or do i need bigger or would a stock intank and a 255 inline work. Thanx for any help oh yeah does anyone know how much witfield(formerly rage)performence charge for tunning. Oh also what would be a good price to get chrome pro put on my ecu and tuned .I already have a ziff soccetted ecu with a reburnable chip.

 

dsm 450's will max out around 300 HP. if you really wanna get above 500 hp. upgrade the fuel pump to at least a 255HP or bosch 044. throw some 1000cc injectors in it.

 

Appropriate size is dependent upon the amount of power used. 1000cc MAY be necessary, but not a must.
