Can't say enough good about Ripp. Been running it ( with MBRP cat back) daily for about 10k miles with 0 issues. It's no " sports car" but improved drivability and fun factor. Only draw back is the switch to premium fuel... But you gotta pay to play!
( currently running 31s and 3.73s, moving to 35s and 4.88s as soon as I get time to install them)

I keep hearing stories that the 3.8 cant handle boost through the bottom end. JP magazine just printed that. But i see this and hear from hundreds if not thousands of ripp owners going strong. Two cases of failures i read about were dry crank from low oil. I think the 3.8 is good motor but just needs help on power.

There's been a lot of good discussion on this thread. I have a RIPP SC and love it. See below for my rig specs. First off the RIPP produces about 8lbs of Boost max or you would need to consider strengthing the bottom end to handle the additional power. Second, consider the type of off-roading you will be doing before regarering. I run 4:88s here in ohio and it suits my needs well. Also, 4:56 will return your RPM's to stock running 35's. I didn't buy headers because the exhaust manifolds are essentialy unrestricted as the leave the enging. Increasing pipe size will get you the same thing essentially and is way cheaper. It also helps to have a good CAT Back exhaust also. RIPP comes complete with a Diablo Tuner. Pretty easy to use. Good luck in what ever way you choose to go...
Just FYI.

I run more boost than a stock kit and havent had any issues with the motor. Still runs like a champ.

The 3.8L with a Magnuson supercharger produces its maximum hp with only 5 psi at 5200 rpm and the torque curve peaks out between 2500 rpm and 4500 rpm at only 4 psi.
