Any and every engine not mater how many cylinders, configuration or size will benefit from having its rotating assembly balance. If the factory piston and rod weight 100 grams together & you replace it with an aftermarket piston & rod which is either lighter (75 grams) or heavier (125 grams) the factory balance is gone. And yes it isnt the 60's, so why wouldnt you do a process to engine that is done by every professional engine builder and has proven result time & time again? BTW my weight #'s are just examples. Im well aware that the factory pistons & rods are lighter than a set of CP's & Pauter.

Yea mine is balanced. The 1nzfe shortblock we offer comes balanced... I can't compare a non balanced motor because every one we assemble is. The machine shop who handles our motors includes balancing the rotation assembly in the process. Rods come back numbered for specific assembly order. My built motor has over 40k on it now ( not easy miles , trust me).... is it because it is balanced ? I couldnt say

Blown: Im not surprised @ all that your motors is balanced. There is absolutely no logical reason not to. The next thing you know someone is going to say that blueprinting is a waste on 4 cylinder........

I never said don't do it, or that's it's a bad idea, or that it won't make power.

Now I'm going to have to ask and find out if, after all that, they balanced mine too. I didn't think so.

At no time did I claim you said " don't do it, or that's it's a bad idea, or that it won't make power" so I dont understand why you would need to defend a statement you never said.

Weather or not it was done to your motor or Blowns motor is not the issue here. The issue is how can anyone say this:

"balancing a four cylinder engine is just a waste"

or

"but Inline engines dont inflict the type of counteracting forces on the crank that the V styles engines do."

Is it time for a Thread Summary?

Reading again, I don't see that there's much of an argument in here.

Just to chime in,i know many people with 4efte forged engines that have not been balanced and doing fine. This doesnt mean that you shouldnt do it but just to show that it may not be necessary.

I have been told that if you dont go above stock redline then you can get away with it.

I could only wish I was building NHRA funny cars, but actually the red and green cars are Pro Mods & the blue is a Top Sportsman.

Colin Chapman also never drove a car he built. I wonder why, Nor did he ever build street legal vehicles.

There is a gigantic difference between a leave no stones unturned spend every penny possible race car and a street car.

If I was going to put $40k into an engine of course I'd balance it. It would be dumb not to.

But if you are trying to get people who spend a few grand on a turbo kit, tune it themselves, and maybe spend a few hours with a professional tuner to make a $13k car hit 130-150hp, I just don't see the point. Unless you are going to tell me you'd charge someone a flat rate of two or three hundred dollars to do it, I don't see the need for it on a street car or even a car that is auto crossed on a local level.

And yes, on a big block from the 60's it would be worth it, as it would probably make more power. As Dent guy mentioned, if it isn't necessary on a high powered Supra, I doubt it would be necessary on a street driven Yaris.

Do you see the point if they intend to push it to 250-300? Because that's what's up on this build.

Let's just leave it alone, guys and enjoy the hell out of pimp's build.
