OH MAN, that sucks, no first gen Probes in Australia! That means NO TURBO PROBES, BOOOOOOOOO!
OK, here's a breakdown for you of all the first generation probes.
89-92 GT TURBO - 145hp, 190tq. Adjustable suspension. 15" Aluminum rims, ground effects, looks nice, very fast, 2.2L Turbo Mazda engine
89-92 GL - Same 2.2L Mazda engine, but no turbo. 110HP, 130TQ, 14 inch rims, no ground effects, basically it's the base model..
OK, now for the LX's.
Only the 89LX came with a 2.2L non-turbo engine, it was basically the same thing as a GL but with all the options, I think the LX meant "Luxury"
Then from 90-92 Ford realized that for a Luxury vehicle the LX was underpowered, and it decided to throw in a very lively 3.0L V6! The silky smooth V6 was a perfect match for a luxury edition Probe...
The 3.0L V6 came with 145hp, 160 torque. The advantage of the GT is that it's got 30 ft. lbs more torque... even though it's got the same horsepower.
12 Valve (2 valves per cyl)
Pushrod engine (ancient technology, but it works!)
Also, the 90-92 LX came with the same 15" rims as the GT. The LX did not have any ground effects however. The 3.0 LX weighs about the same as the GT, 3000 lbs. Even though the GT is a 4-cyl and the LX a 6, the GT has extra ground effects, intercooler pipes, intercooler, turbo parts, etc that even it out.
Also, the V6 LX came with a dual outlet muffler like the GT while the GL came with a single outlet.
ONE MORE THING, I think the LX was the only Probe that you could get a digital dash with... the tachometer, speedometer, odometer, and all the other guages are all digital which looks pretty cool but it does not show over 85 in MPH, but it does show higher in kilometers per hour....
The GT had analog guages that go up to 120 mph.
Uhmmmmmmmmm.. I cannot really think of much else, if you want to see what it looks like check out my website!
