i have a 1995 m reg classic impreza, and it running 315 bhp at the minute, i have just had a full engine re-build including, forge pistons, rcm top and bottom bearings, rcm uprated oil pump, i have been told to get a fmic,

WILL I NOTICE A DIFFERENCE WITH THE CAR!!!!!!!!!! AND WILL I NEED ANYTHING ELSE i.e better fuel pump or something!!!!!

 

will you notice anything after the rebuild do you mean? if so, no. new pistons, bearing and pump wont give any more power, in fact the new engine may be down on power now as it will take a few thousand miles to loosen up.
if you fit the fmic and get it remaped then you may see an improvement due to lower intake temps. always a good idea to upgrade the fuel pump as the oe one will be tired now.

 

thanks m8, i ment after the fmic mods!!!!!!!!!!!!! i think i will have to get a one then!!!!!!!!
