What changed between 93' and 94' on the body? The grill? Maybe?
Engine wise, a few things like EGR were added, mostly emissions. Some Manifolds were changed, and the fuel system lines on the 3L. A change from R-12 to R134A refrigerant? Not much there.
The main differences between a 93-94' and 95'-97' Gen III's are:
1). a switch from EEC-IV to EEC-V(witch called for different wiring routing, placement and design of things like the overflow tank, etc, and emissions equipment)
2).the dash/trim/door cards, and HVAC systems(so the bulkhead of the cap is "slightly" different)
3).grill
4).wheels(style)
5).the front beams got reinforced with more welds and more material at the lower ball joint
6). better dual piston caliper front brakes
7). exhaust changed a little (flanges between the y-pipe and cat) & some manifolds were revised.
8). I think they revised the carrier bearing design a little(but that may have happened halfway through 94')
9). the master cylinders are different(but can be swapped between)
10). the cruise control setup is different
11). they changed how the clutch master was mounted (actually on the bracket, and not through the firewall)
12). ignition systems where upgraded from TFI to EDIS on the 3L, and from DIS to EDIS on the 2.3's
13). power options were alot more common
14). and ABS and airbags became standard
15). auto transmissions became computer controlled
16) Speedometer read off a sensor at the t-case rather than a cable.
17) They changed how the radiator was mounted.
18). Core support may be a bit different.......
19). Overflow Tank
20). Air Intake, and filter
21). Plastic Intake and combustion chamber design on the 4L
22). Heads reworked on the 2.3(intake too)
23). Batch fire to actual SFI. (which led to the crappy CMPS on the 3L)
24). How the wiper blades attach are slightly different, so is the motor that powers them.
25). ?Fuel pumps?, fuel lines/fuel rails(returnless), injectors changed, EVAP system.
Did I miss anything????
