Look in your VIN #. Its the eighth letter/number.

91 TBI is the 4x4 was 165 hp, 92 W CPI was 195 hp.... 8th letter of your vin will identify your engine. CPI has both different fuel injection and cam size than TBI. CPI was available from 92-95, both CPI and TBI ended in 95... Both W and X motors from 96 to current use CSFI. Differences are ecm programming and the X engine has a smaller cam..
