i have a u13 bb motor but i did not recieve a maf with it can i use my stock sr20de se-r one and if so what are the differences between the 2? thanx in advance

need to know asap

i use mine that way, only issue is i run rich, but it still runs great.

nope, u cant use it, u have to have a bb u13 maf, or as i believe a gtir maf will also work, but for sure the maf has to have the part number 54cxxxx, not 53j, how do i know this? i have a u13 ecu.lol tried it and it doesnt work and the car ran like absolute shiate!, good luck finding that maf, they are hard to come by, if i can make a suggestion...buy jwt and save the headaches or run a piggy back with ur u13 ecu (safc) and run a diff maf like a z32, its what i had to do.

he said u13, not u12.lol

oh well. lol

thanx for the bad news guys. lol
