[need2drift]

what kind of motor are these going on???

89-90 ka24e is top feed91-98 ka24de is side feed

just in case its an sr20 its sidefeed aswell.

i figured it out. they're top feeds. now all i need is the safc2.

[need2drift]

is this on a ka24e??? If it is I wouldnt get an safc, just get your ecu socketed and burn eproms.. the ka24e ecu uses one eprom, its easy to remove and put a socket in its place.. then you can take the eprom out anytime you want to change the tune..

how would i tune this thing? and how hard/expensive is it to do? i kinda want to have something thats been tried and tested, u know?
