diesel conversion to replace a 2.2ltr chevy
I have read a lot of the suggestions posted here. A 6.2/6.5 could be "shoehorned" between the fenderwells, but the guy that said it would fit where a 350 came out....isn't necessarily correct. The width of the 6.2/6.5 engines with exhaust manifolds mounted is more comparable to that of a big block gasser such as a 396, 402,427, or 454. True the motormounts and bell housings are in the exact same locations, but the top end of the motor is wider than a small block V-8, and will not easily fit between your fender wells ( I know because I have stuffed a few S-10 engine bays with 350 V-8s ). If its economy you are looking for, I would suggest replacing the 2.2 with a small 4 cyl diesel such as one from a bobcat skidloader. The engines are about the same physical size as your 2.2, and an easily made adapter plate to bolt the transmission ( auto or manual ) to the bell housing. A 6.2/6.5 would be like planting a 350 under your hood, and you'ld have to change the rear axle, tranny, and wind up spending a ot more than necessary....and in the end not get much better fuel economy than you currently get with the 2.2....considering the difference in the price of diesel over unleaded regular. The suggestion to put a VW diesel in could work, but you would see more usable power from the commercial equipment 4 cyl than you would the tiny VW. If you ever decided to pull a trailer, the VW would have a lot of trouble getting motivated as well. They were designed for VERY light vehicles....not something like an S-10. Another consideration would be a small inline 6cyl Diesel such as from a Nissan Cressida. I know a gentleman who put a toyota 6cyl diesel in his 1978 F100 ford pickup, and it does great and is very economical....and with a turbo, has good power too.... Like some have said, it all depends on your goal in the end, and what you plan on using the truck for. With Fabrication, you could slam a big 3406 cat diesel in the engine bay if its pulling power you want.
