compression

[cys19]

Will slapping a turbo kit on a ka24de wear the engine out more than the sr20det? Sr's compression ratio is 8:5 while the ratio for the ka is 9:1. Comparisions please; I'm a newbie.

You wont be able to run as much boost with the ka. The lower compression on engines built for turbos is so they can run more booste safely.

Good tuning will allow to run more boost than most people think the "truck engine" is capable of. That .5 of compression isn't the world.

oh nooes. high compression go boom.

No, kidding. Take a look here and see what can be done on a stock ka with good tuning.

Good tuning and strong internals will help you run highboost with a high compression cars. I think that the E-55 runs 11:1 compression supercharged. I will have to check.

Good gawd!

On pump gas??

The 1.8T that Audi and VW uses runs 9.5 to 9.3:1 These cars make 150-180hp. And the E55 AMG has 10.5:1 compression.

To answer your question, adding forced induction to a motor not designed for it will have a greater likelihood of engine wear. So will modifying your engine, abusive driving and not maintaining your engine. Engine wear and the ability to safely run boost are two separate questions. You can run boost on any engine you want, but you will have reliability issues and longevity issues depending on how you do it and how the motor is setup.

So let's take a 544whp SR and compare it to a KAT with all the same type of mods the SR has. Say it also reaches 544whp or higher. Will the KAT wear out faster than the SR with all other things constant--same driver, etc.?

is using a thicker metal headgasket to lower the compression ratio considered part of a stock motor?this is what some of the higher hp SR guys have done. Try it out with the KA. Anything thicker than 1mm should do.
