I have an early 99 and I recently came across on a good buy on a late 99 complete engine. I already plan to swap the turbos with a whicked wheel or something similar but I was wondering if there is anything else I should swap over. I bought the truck from a dealer and I am the second owner. I do not realy know what is already done except I deleted the cat and did a diy intake. Gauges will be here shortly and I do plan on getting a tuner in the near future. also I am guessing it is still the stock motor with about 337000 miles on it...
