After owning a kubota powered excavator for 6 yrs with zero issues, I decided to use a kubota engine in my newest project...it is a very rare aluminum micro jeep with independent suspension...
I was unhappy with the original air cooled V4 gas engine, so I transplanted a V1505-T engine into the lightweight Mighty Mite...had to have an adapter plate made to fit the 4 speed tranny, and a combination of off-the-shelf clutch parts.
After a few months of researching, and collecting parts, and a weeks worth of labor, I have it up running and drivable.
Wow is it fun! Torquey, and quick...and an added bonus is that the little 4x4 now gets in excess of 40mpg!!!
Knowing I would be pushing the little 4 cyl hard, and that I would be wringing more power than stock out of it, I decided to go through the whole engine I bought.
I installed new pistons, rings and berrings. Also, more importantly, I added piston oil coolers to the undersides of them...I did this by having two tiny holes drilled in the con rods and also had the rod berrings machined with a U-groove in the center with holes that match the new ones in the rods...this way pistons get a constant spray from two oil squirters.
I removed fuel rack stop screw, throttle stop screw, and turned in torque screw one turn. Lastly, I installed an extra spring on the wategate for more boost...
The power is awesome! Boost pressure jumped from 7psi stock to around 14psi...
