4BY

[yamaha1371]

Thinking of purchasing a 1990 blazer and throwing a 4BT with a 5speed in it. Not worried about fuel mileage just looking for torque and hp... throw bigger injectors, turbo, cam, P pump, should i have it fire ringed and studded??. Know a little about the 5.9s not to much about the 4BT though...except that the 3.9 is the 5.9(-2 cylinderz)
