ive just fitted a wrx engine in my 99 uk impreza only has 47k on it fitted new cambelt,plugs,oil change, all necessary stuff for full service before fitting.. i have a full de-cat exhaust with open bell mouth,td05-20g turbo with adjustable trs acctuator,front mount intercooler, induction kit gc motorsport paddle clutch, twin piston dump valve, silicon hoses.
wot power do you think i should get and wot boost is possible any ideas or advice please........????????

 

What ECU? What size injectors? what boost level?

 

running the standard ecu wich i believe is an ecutek, standard injectors, dont know wot boost it has at moment as not qiute finished but any ideas wot iwil get when mapped?

 

You may want to think about changing the injectors to 550s or at least fitting an adjustable regulator to get more headroom from yours (440cc).
Im running 90% idc on 550s with a big 16G @ 1.5 bar.

You dont want to be running much over 330 on the standard engine & box.

Im sure someone will be allong who has a 20g to let you know the boost levels possible on 440s or 550s
