Zex is by far the easiest to hook up, but like T8 said the solniods look a lil on the wimpy side. They look like the N.O.S noids I had on my single cam civic back in 1998
I actually am running a zex kit. (purchased for 300.00 brand new

) It took a 3 guys to install the kit in about 5 hours. It could of been done alot sooner but my friend Mike is anal about ANYTHING automotive and anything that has his name on it willbe installed the best he can install it. We also took time to hide as much of the system as we could.
Anywho, really simple install because of the nitrous control module and yes it has a build in TPS activation switch.
