as seen from the title above, i suffer from low oil pressure....low rev is ok i think, since idle stay at 1 bar plus, crusing stay at 2 -3 bar.....how ever, the oil pressure stay same when i full throttle and rev, when high rev till vtec and boost kick in, pressure dropped to 2 bar only new oil pump needed? where can get it? and got aftermarket pump that is more efficient and powerful? will that cause problems if i drive it normally(not rev past 4k rpm and no boosting)? please...
