In 93 Ford's method for measuring hp was changed to where it only put out 210 fwhp (or was it 200?), there's a lot of people who think the reasoning behind this was so when they introduced the 94, the hp rating would go back up to 225. But, 93's do have the hyperpathetic pistons that don't take too well to too much boost.

This might be a lot to read but i think it will answer some of your questions. i copied and pasted this from http://www.mustanggt.org/93gt.htm
Although there were no mechanical changes from 1992 to 1993 (aside from hypereutectic pistons replacing the previous forged aluminum pistons), both the horsepower and torque ratings dropped for ‘93 - horsepower by 20 and torque by 25. The reduced ratings were influenced by a stack-up of minor mechanical changes and by changes to Ford’s engine evaluation processes. Dictated mainly by emissions, fuel economy and customer satisfaction requirements, a series of mechanical revisions had been made since Ford initially assigned the engine’s 225-horsepower rating for 1987. These include a restrictive resonator added to the inlet tract (1987-1993) that produced a 5-7 horsepower loss. The small camshaft profile change in 1989 reduced HO output by 3 horsepower. The restrictive mass airflow meter in the inlet tract introduced in 1989 yields 2-3 horsepower less than the speed density system. Some minor exhaust system revisions made between 1987-1993 also add up to another small reduction in engine output. The second contributing factor in the re-rating of the ‘93 V8 involved changes in the processes that Ford used to select engines for testing and the engine’s state of dress (with all engine-driven accessories) during testing. Combined with the ‘87-93 mechanical revisions, the revised-for-1993 testing procedures add up to the ‘93 model year’s reduced output ratings

From 1987-1992 the horse power was 225hp and 300 ftlb of torque 1993 was 205 and 275
The 92 and lower were rated at 225hp b/c they used different methods of testing. The 92 and lower engines were ran without accessories, 93 is when they started rating engines WITH accessories installed. The 93 has the same HP as the others.

what about the 93 cobra?
93 Cobra came with close to 280hp at the flywheel I belive. They came with a better cam, 1.7 rockers, gt 40 heads and intake. Also 3.55s im pretty sure.
Edit --- This was taken from another post, here is EXACTLY what the cobras came with
Cast iron GT40 heads Cast aluminum Cobra intake manifold Crane 1.7 rocker arms 24lb fuel injectors Cobra specific ECU (computer) "Cobra" stamped valve covers with build sticker and signature Engine oil cooler Front mounted power steering fluid cooler Lightened flywheel Phosphate coated transmission gears Overdriven waterpump pulley Cobra specific camshaft Cam specs: Duration: 227°/Intake & 270°/Exhaust Lift: .485/.485 Intake/Exhaust Lobe separation: 118.5°
This is just a little extra stuff specific to the 5.0 Cobra as well. The interior and exterior differences arent listed because I figured they were obviouse enough.
Suspension/Brakes
13" Front brakes 11.65" rear brakes "Cobra" embossed front calipers Cobra specific brake booster Cobra specific rear sway bar Cobra specific shocks/struts/springs K-member that is slightly stiffer than the GT's No strut tower brace
Thank 94Cbra for this post.
