I am starting to gather the parts to put an Isuzu 4bt1 in an s10 truck I hav installed a 2.2 Mazda motor in a 1984 s10 and found the power barely enough, I have never made an adaptor to hook a 4.3 ltre manual tranny to the Isuzu motor and would appreciate any advise I have 3 s10 now 2 extendes cab one with the wcode 4.3 with 200 hp 2 wheel drive automatic and a 2.2 with the 5 speed One is good on fuel while the other has lots of power I am hoping this disel conversion will be the best of both Any advise would be valued
