Guys,
How about putting it on a dyno? If the 2.4T engine was rebuilt with different components, you would see a significant difference in hp. Your 73T was suppossed to put out only 140 hp @ 5,600rpm's. If the engine was rebuilt to S spec's, the dyno would show that you are putting out something in the neighborhood of 190hp @ 6,5000rpm's. For an RS, you would be putting out 210hp at 6,200rpm. Granted, this would not let you know exactly what is inside creating the extra hp, but it will give you an decent idea. If the dyno testing shows good output, do a leakdown and compression to see what kind of condition the engine is in. If the dyno test and leakdown/compression are satisfactory to you, put it back in and plan to re-build it when it breaks instead of worrying about it now!
