I have a question about engine block modification. I was wondering what it means to getting your engine sleeved for the Srt-4 block. What possible gains and advantages could I attain?

Typically getting an engine sleeved means to have iron sleeves pressed into the bores for a stronger cylinder bore.

I'd be surprised if the SRT block wasn't sleeved.

You most typically sleeve a block that has had damage to a cylinder and you need to save THAT EXACT block for one reason or another. Most times it's cheaper to just get another block. Sleeving a 2.4 block just to do it would exceed the cost of getting another one in this case. Any minimal performance gains would be negligible and not worth the money.

I hope this isn't the next "I gotta do this too" thing for srtforum people. They'll be sorely disappointed and won't like the cost and effort involved.

Some engines come factory sleeved, but DCX would have never put that much expense into an econobox engine, let alone a high end one. The only possibility of a sleeved factory engine might be the Cummins diesel, but I am too lazy to research it ATM. There are other potential problems if the sleeves aren't installed 100% correctly also. It would be a warranty nightmare on a 4 cylinder with a bi metal engine, and the general public combined.

Now an all aluminum block with iron sleeves would be

The performance gain would be the weight loss.

It's not worth the time and effort, leave the block std in bore for strength and only bore it if needed. Most Japenese engines are sleeved but the Chrysler motors are not.

Chrysler engines are already strong. No reason to sleeve them.

Properly built he is correct

Wow, what a complete brain fart. I forgot the blocks are iron.

Yeah, if they were aluminum, we would have no spare engines.

Sub humans would be stealing them for scrap value, every time scrap prices jump.
