and ae92.... seeing how i'm close to a full "conversion".... here goes..
sr5: 4afe (90-102hp depending on year) dohc slave-cam style motor.... weaker internals, economic head design...... no front sway bar, non-serviceable struts, no voltmeter or oil pressure gauge, interior is different (seats, gauges, sr5 has the 3rd brakelight on the rear dash), no sideskirts, no stock rear spoiler, 13" rims, rear brakes are drum brakes, (later model ae92 used larger brakes as well), c50 transmission for manual, auto's were available
gts: 4a-ge (115-135hp depending on year), DOHC twin cam motor.... more aggressive head design with much higher rev limits.... had front swaybar (23mm), rear disc brakes, voltmeter/oil pressure gauge, sideskirts, rear spoiler with 3rd brake light, 14" alloy wheels, optional serviceable struts.... c52 transmission, auto's were not available
