So, a couple of issues have come up:
#1 - the turbo is in need of a major rebuild: New turbine and shaft, compressor wheel, etc.
#2 - the front seal on the engine leaks, very badly. (It should have been rebuilt before I installed it...oh well.)
I weighed my options and costs and decided to begin a casual search for a V6. Not just any V6, but an aluminum block V6. I want the power and torque of the V6 without the mondo weight of cast iron.
A mighty miracle occured! I scored a 2006 XL-7 for a VERY good price with only 76,000kms. So now, instead of a 80 hp hamster, or the 100 - 120+ hp hamster on a leaf blower (Thanks Chris), it'll be a 185 hp dual overhead cam, 24 valve, raging fury!
PLUS I'll be running the 5 speed auto tranny instead of the 5 speed manual I'm currently running.
The XL-7 when I first picked it up.
The reason it was cheap.
Naked XL-7! It's amazing how many similarities in chassis design and dimension between the old and the new.

I did all this over the course of two long Saturdays. Now I just need to fab up some new engine mounts! The tranny mount should bolt right up, in the stock location.
I'm sure some of you are wondering about the driveline: Yes, the tranny is about 5 inches longer, the front drive shaft from the XL-7 is longer than the tracker original and will bolt up, the rear drive shaft will have to be shortened approx 5 inches.
