Im gonna do a H22 Swap but I want turbo where i can run a good amount of boost and I keep wondering if an H23 block is goin to hold up better than an H22 or is it the same and should I sleeve both, and my next question is How much boost have you ever seen run safely like this?

 

same blocks

 

so what are you sayin, the H23 block is basically a h22 block bored so it has thinner cylinder walls?Please tell me something

They are pretty much the same (aka casting)

meaning only the internals like crank,rods, and pistons arent the same. the blocks are identical.

 

the sleeves are made of different materials as well, but both motors have the same bore...it's the h23's use of the f22 crank that gives it the longer stroke, creating the 2.3 liters of displacement...

 

Would I just be wasting my money goin h23 block or should I just get an h22 and sleeve it 4 turbo?
