Best block to build a boosted motor I have a torn apart L33 which I was planning on using for a turbo build but I'm just looking for some opinions on if using this aluminum block is the right choice or should I look for a steel block? I liked 799 heads which is why I sourced out this block but before I spend all the money on a build Id like to hear some opinions. Thanks for the help.

Depends on your power goals and what you will use the car for.
The strongest, most bullet proof you'll get is an iron block....and then sleeve it with Darton sleeves. Just about indestructible.............
But even for builds under 1,000-900 RWHP, aluminum is fine, but still.....why not buy an extremely cheap $300 iron block LQ9......save more than $1,500 over going sleeved aluminum block. And the iron is MUCH stronger. More re-build able. Hurt a sleeve = EXPENSIVE fix. The extra weight is meaningless, so don't listen to that excuse. It makes zero difference in a street car. You will feel absolutely nothing from the extra 114 pounds up front. I went iron and my car handles and feels 100% identical from my aluminum.

Thanks for the advice guys. I know iron is stronger but this is the block I currently have apart and it had the heads I liked so from the sounds of it I'll be just fine building it into a street turbo'd motor for my c10.

Whats the past use of the L33 block and has it been bored? should be fine unless its been built before and has thinner cylinder walls and passes a magna flux test for cracks, built that boost monster and do your best to break it! Just have fun along the way
