unless your willing to install ATTS in your car it's not worth the trouble. as I was going to use the SH motor and the complete ATTS system in my 5th gen was half way done installing ABS (Lx model) as it's needed for the ATTS to work and the deal fell through and ended up getting a non Sh motor. but it's not a simple drop in it requires alot of wireing ,adding sensors ,extra computer for ATTS ,new radiator with the cooler for the ATTS unit also the immobilizer unit has to be installed or it won't run.
