CX Racing has been around for several years. They make good $$ cuz they sell kits that are like 1/4 of the price of a real, well designed, complete turbo kit. It's just like a cheap Chinese Ebay kit. Thin walled piping, weak clamps, and poorly fitting couplers. There are a few guys on the MR2OC Forum running their IC's (the only good thing in their kits), but even those don't come with a fan or shroud.
So if you just want ANYTHING to make you more power, without regard for how poorly constructed and poorly fitting it'll be, knowing you'll have to likely go back and redo it later, sure, they're an option

Otherwise, just remember that you get what you pay for.
Unless I score a BNIB TRD Supercharger someone's been holding onto, I'm gonna prob. take the plunge and get the Sprintex unit, but use my own air-to-air IC via a hood scoop (like a WRX). Stock fuel system though. The truck is the most reliable thing I own, even though it's one of the oldest things I own lol. Trying to keep it like that
