to my knowledge there are a total of 3 known srx piped vipers, 1 real one and two kindas.
mine was the original, i later removed the viper engine so i could sell the sled as just a srx engine and pipes(less of a cluster @$!#$@). I then sold the flange extensions to a guy on here who made the rest of the kit himself. His is the only real srx piped viper in existance to my knowledge left.
another guy on the site installed all srx motor, pipes, wiring, and even guages.
the last is my kit i sold a month or so ago, this was installed in a viper with a 98 srx motor, viper wiring, and all the stuff from my sled to finish it off. i dont think he has finished installing it though as i havent been called for questioning yet on any details and there are no pictures yet.
as for my sled, i made it an organ doner.
to do it yourself would take a weekend and a set of pipes, 01 srx cdi box, some welding and building ability. also, a mega power water rail, if you want to use srx heads.
if i was to do another one i would just use the viper head and just machine the domes to 22cc with the bands recut. the viper head works fine. if you use srx heads, you should use the srx base gasket or you will end up with the center cylinder either hot or cold, cant remember what way it went.
if you decide to do it i have a flange that was cut on a plasma table to make the manifold extensions on if you go that way.
