stock 4g64 (2.4) bottom how much power?
just curious to know if anyone has ever run a completley stock 4g64 short block with thier evo head on it.im curious to know what kind of power they can hold up to.please dont come on here and say "you must build it,etc or else"i know all these things and i know of the consequences of pushing a stock motor but at the same time i want to know if any has done it and what are thier limits.im thinking about just throwing one in my evo for daily duties.....any help would be very apreciated!

yes thats exactly what i want to do.it would make more because it has a better head (evo).im not trying to make crazy power or go for records,but maybe like 300hp more or less.again the car would be for daily driving not racing.

hmmm still dont see the point in this unless your going for a record to break. the whole point of the 2.4 is to get more of course if you want strictly dd with no bs then keep it stock 2.0. if yours is damaged then i kind of understand but you can buy a built one for just alittle above 3k yes you can get used cores for like 500 lol.

The OP isn't asking people what the point of such a swap is or if it makes sense.
@nos51: Sounds interesting. I'm also curious how much power a stock 4G64 can make on a 16G. English Racing recently put a 16g on a built 2.4 and made insane amounts of torque with HP falling off after 5500 RPM. It really maxes out a stock turbo quick. You can look forward to 400WHP pretty easily though. Here's the thread I'm talking about:

Stock 4G64 bottoms come with pistons designed for a N/A application. They don't have a friendly compression ratio for F/I nor are the pistons designed for it.
I have heard of people getting 300-330whp out of them using around 16psi of boost, but I don't think that will last very long.

I understand that, but you have better pistons and rings designed for a F/I application. You also have it tuned correctly. People who know what they are doing can run higher compression on a well tuned turbo car, but that doesn't mean the same as pulling a bottom end out of any N/A car is going to get you the same or better results. Especially not with pump gas. He mentioned nothing of E85, meth, racing fuel or anything else to help reduce knock.

Yea I know all of this stuff......but this doesn't answer my question...trust me I know the difference between a motor built for na and a motor built for boost.a stock k series is built for na 11:5 compresion they make 550hp all they and hold it too.

I worked with the stock 4g64 for years. Based on my experience the bottom end will hold 300-350whp all day long. I have not seen it pushed much further past this but an educated guess would be somewhere in the neighborhood of 400-450whp will probably be near the max of what the internals will hold.
