1) why 6.7 i bought a mega cab that was an oil field truck for 4,000 bucks. so i could not pass it up. i got 3,700 including the 1500 in parts after i sold parts from the megacab. 6.7 can spool a 66mm turbo like a 5.9 can a stock turbo pretty much.
2) im running the 1500 leaf springs cause the 2500 ones are about 3/4'' wider. i will be doing track bars for now in the winter going to a 9'' with a 4 link.
3) its not to bad to do the wireing just have to be yell to blow steam so i dont break anything lol. i have full wireing so kinda had a head start.
4) its easy man dont be jelious you can easyly do a 12v
