The thing that lobux left out is that when you raise the redline you also raise heat. Meaning that you need a better cooling system if you plan to keep it up very long. Second, you will find that the bottom end also needs to be well balanced in order to keep the engine together. The oiling system also needs to work well or things will seize up. Most small import engines are well balanced and the cooling system usually works very well. Raising the redline is dangerous thats why its there. Toyota knows what they are doing. However that doesnt stop us racers. Just know that most real race engines are torn apart ever ten runs or so. Even the good ones. Doing all this head work and changing the redline is great But keep in mind the bottom end is just as important as the top end. My friend runs a power programmer on his truck. Mostly its for changing the top speed and for changing shift points, tire sizes, ect to make it pull or race better. However it only changes these things and not the overall power. You may see small gains from changing the fuel to air ratio buts thats about it. This may be what your freind feel.

It depends on if you consider pistons bottom end. You can get a significant hp increase by going to higher compression pistons. The same thing you are doing with the turbo or supercharger only supercharger is a bolt on and pistons are not. Thats what us naturally assperated guys have been doing for say um 50 years. IE domed pistons and hemi heads. I agree a significant amount of power can be had with a port and polish or a stage 53000 head. but that doesnt mean that thats the only way. By the way Kenny Tran didnt think the bottom end would hold up. Or thats just my interpretation since he installed new rods and pistons on his 500hp beast of a tC.

Toyota bottom ends are legendary. The 2JZ in the Supra has made over 800 hp bone stock from the factory in daily driven cars. I have no reason to doubt the 2AZ is any different, despite it being an aluminum block.

Your words not mine. If the supra has 800 hp bone stock: A. thats amazing for a steet car that would still be managable since most V8 race engines for street cars are only pushing about 1000hp and thats for a car well into the 9s. You think that a 500 hp tc wouldnt be managable but you drive a 800 hp supra. B. you said Toyota bottom ends are legenday and then say that triple the hp you wouldnt expect them to hold up. Make up your mind.

Sorry guys this is my last off topic post. I just dont agree with the heads and super flow being the only way to get Hp. Ive seen many naturally asperated engines run like h*ll. Building a high hp motor is like Karate Kid "You must have balance."

Ah screw it its like talking to a women. You will never win because they have no need to makes sense. You said that you wouldnt want to drive a 500 hp tC on the street but you make no complaints about a 800hp supra. Sounds like you are making up numbers to me. Hp is hp it doesnt matter 800 is huge 500 not so. so why would you tell people you dont think 500 is streetable but 800 is. It makes not sense. Do you just read magazines and try to baffle people with all this technical jargin. I know alot of engine builders that barely have a High school diploma and they build race engines that last all season long and put out huge horsepower. I may not be one of them but I know a little bit about cars and alot of other things. So what if you can amaze us with technical talk all day long if you cant form a paragraph that makes sense to anyone with that knowledge, than it means nothing. By the way you are only trying to lower static compression in asperated engines because you dont want to over compress and blow the engines. In naturally asperated engines you want compression. not the lack of. Besides you talk like V8s are dead. I like the 4 cyl because it puts out a little hp and gets good gas mileage. By the way you said 500 hp from a tc is crazy and unstreetable. I know alot of 500 hp v8s that are plenty streetable and can run for years and years the same cant be said for the tc motor. so I guess there not so extinct now are they.
