Me and couple friends,we use to buy honda motors from them and We had a lot of problems and that had an end when after 5 swaps"motors from them" with fu***d motors in one of my s13s,“I having the 5th motor blowing the con. rod out of my bottow end in the faces of one of his own mechanic in my garage” I decide not to buy motors from them,unless, it is done the compression before I get it to my home and not only "startup"warranty.
There is a lot of places that can sell u good motors for a good price,but,MAKE SURE u do the compression before u get it to your home.
This is only my 2cents for u to get a nice motor.
