a cummins swap is a huge project!! think of a sas with 3 link and coilovers, and then double or even triple the complexity especially in the newer rangers with pats and all that good stuff. ive been researching for a while now, id love to do a p pump 4bt backed by a 6sp allison w/manual mode and a 4spd atlas behind that. 4btswaps.com is the best site ive found so far regarding cummins swaps. glad to see im not the only one interested in diesels on here, getting a little sick of all the v8's.
