Reving wont go past 4,000 RPM
Does anyone know why this happens? I tried reving my car in a parking garage to hear how the intake and tanabe would sound and it didn't let me go passed 4,000 RPM or so. This is the first time I rev it while in park, I dont like abusing the engine so much. I appreciate your help in advance..Thanks.

I haven't really tried either yet, but why would it be worse to rev your car while in park (at full operating temperature) than while in neutral? The car isn't in gear either way, right?
And if you did it in neutral, what's the point of doing it while rolling at 5 mph rather than stopped with your foot on the brake?

worse. Revving the engine can dump gas on the cylinder walls, which
increases engine wear and wastes gas.
While a little reving wont do anything, to much can. Did you know that just having an engine on idle (having the car on but not driving) is one of the worst things to do, it can cause the most harm to your engine. Well reving in idle is basicly the same thing only now your putting more work into your engine, hense being worse. Engines are built to withstand these things though, so again a little wont do much harm but a lot will.

Trust me I will never rev it again in park or neutral. You guys have my word on that lol. Thanks for all the help. Glad to know our cars have a rev limiter to prevent stupid things like this from getting worse.

Revving the engine with no load puts tensile stress on the rods. Rods work fine when being compressed (under load) but don't like to be stretched (in tension). Many old school mechanics will tell you to never rev an engine with no load, and this is why. Modern engines are not nearly as sensitive to this, but it still isn't a good idea. While it is extremely unlikely to cause catastrophic failure the first time you do this, it is possible to stretch the rods permanently.
Also keep in mind there are any number of troubleshooting procedures that start with "run the engine at 2500 rpm for 120 seconds." So it's pretty clear Toyco is not worried about running the engine with no load at this speed continuously.
