While attempting to install my newly arrived ZZP belt tensioner and stock replacement belt, I found that the belt was WAY too long and couldn't figure out how the tensioner from ZZP was supposed to work. Their instructions stated that the stock tensioner had to be removed and that required the SC to be removed. I looked at this Atom modified LSJ engine and thought WTF??? I can remove the tensioner with one bolt and it is nowhere near the SC... I decided to take a look at my donor and D'oh! There was all the parts that ZZP wrote about! I then went back to my Atom LSJ and figured out how they ran the belt and decided I liked that a whole bunch better! Anyone with a SC engine car want to buy a ZZP tensioner that can be used with any size SC pulley (stock @ 3.3 down to 2.5, I believe)? I have it and a BFN stock belt I JUST got in that I am not going to use now. Paid $171.63 shipped to my house, will sell for $150 shipped to yours!
