The two available kits:

Low Boost Kit, approx 280 hp 270 tq, $6,500.

High Boost Kit, approx 330 hp 320 tq, $9,500.


Prices provided are without installation (which should not be very difficult at all, except for benz specific tools). And if you are wondering if you can upgrade to the 'High Boost' kit at a later time if you buy the 'Low Boost' kit, yes you can. Difference between the two is the 'High Boost' kit has a intercooler, allowing it t to run higher boost pressures.

i've read reviews on benz boards and most of them agree the Kleeman is the best as far as supercharging these engines goes. I wish i did not have to believe what they say, but these overpriced manufacturers don't offer any information worth squat...

for now, i will enjoy our other car for my speed/cornering hunger... just finished a mopar stage 1 and suspension techniques sway bar on our SRT-4... combined with the 225 width tires on the BBS wheels, dc strut bars, it handles great now... next to come, 300 hp on the stock turbo through turbo porting + ppq piggyback computer tuned by muah 19 psi of boost here we come. :P
