OK, I need some opinions from you diesel guys, I've been making plans to swap my 5.7L TBI out in favor of a GMPP HT 383 (340hp/435fllbs torque w/400+ftlbs from 2500-4000rpms), but have recently become interested in a 6.2 swap instead. The gas milage and the torque are what has drawn me in, but the lack of hp, and my lack of knowledge about diesels is what's making me hesitant. Here's my questions. 1. I figured by completely rebuilding a 6.2 and adding the banks sidewinder turbo kit and bullydog propane injection (and anything else you guys suggest) I would end up just shy of 300hp and somewhere between 510-600 ftlbs torque, is this correct for real world figures? 2. I've never driven a diesel. How would a setup like that feel, with almost twice as much torque as hp? If those numbers are correct they are similar to a new cummins or duramax, could I just test drive a new truck to feel the power, or are there to many things different on the new diesel engines to compare the way they drive (like the difference between carbs, tbi, and efi in gas engines)? 3. IYO, what would be more "fun" to drive, the 6.2 turboed w/propane or the HT383? 4. How much has everyone whose done the gas to diesel swap spent on the 6.2 itself, and then on everything else they used for the swap? Any info is appreciated, I've searched through posts on turbo, propane, and a few on the swap, and learned a ton, but I'm hoping these questions are different enough to call for a new thread. Thanks in advance.
