I have the Tork Tech kit, seeing about 10psi.....making 417rwhp.....Stock bottom end, had it over a year and no problems so far. If your going to be spending money on a kit, don't go cheap.....meaning get an intercooled kit. You won't regret it.
Tork Tech, KB are great kits, both are roots style, meaning instant boost, really fun to drive on the streets.
Vortech, Paxton are centri type blowers which are more street friendly(not as fun though), they do get into boost until higher rpms.
Before you buy, do lots and lots of research for what YOU want. Thats you first goal, decide what you want out of your car and how much power you want. then go from there.
What do you mean as in "more street friendly?"
