Ive never researched into it, but if I ever get a second VX, I was going to try the following- Most Troopers except old gen Troopers and the VX are very similar in the frame, engine, etc category. Possibly finding slightly used or refurbished parts except the engine (3.5 rocks for isuzus) from a pre TOD or a later model manual trooper. Plus the 3.5 SHOULD bolt to a 3.2's tranny (anyone?) This would be a complete change of 5 speed tranny, transfer case, driveshaft, and of course mounting. basically you would have a VX with the previous items completely replaced. Can you imagine how fast a 5 speed would be off the line as stock first gear runs up to 45 mph! Teralows are made for manual transfer case troopers, AND lower ring and pinnies AND some ARB's AND a Supercharger! Watch Out Moab. On a lighter note- at least Isuzu was kind enough to provide us with clutch holes in the firewall! LOL. I think stealing off Trooper parts is the key for any major mods we do Unless fully changing in another manufacturer. Mucho dineros though, and Isuzu has never let me down in 15 years so far.
