The local turbo shop uses the $500 STS kits. I have seen a bunch of mention on these boards about Coolingmist and others. Which one did you use, how much $, and why?

 

coolingmist hfs-3 650 on the initial GB no tank ill have to do my own later.

reason i went with it it is by far superior in my eyes than any other kit so far. tapping into your injector signal and directly mapping % so you can have the EX. 10% to fuel water being injected at ALL range not just max duty cycle like most on off kits even the boost matching ones dump AI at the lower RPM range and tapper to the matched % at the high end.

also if you have a good ecu to add injectors there HSV can be run directly off your ECU same as an injector HIGH IMP if memory serves and then all youd need is the valve and pump essentially with injector matched to % you want to run.

there are so many kits out there do your research on what will work best for you. but also something your tunner will touch.
