Bore

[Super Bleeder!!]

2.0 and 2.4 blocks are certainly not the same casting. their deck heights differ by like 6mm!

I'm just trying to build a 2.0 right now. Once my cars running I'm going to start on a stroker.

And why couldn't the 2.0 just be a smaller bore and be milled down 6mm more? It's only 1/4", which is 2 passes on cast iron. Maybe 45 seconds of machine time.

It might be real similar to a NT 2.0 block, but not a turbo block. Things like oil squirters and a knock sensor hole.

If you're going to build a motor with aftermarket pistons and rods, it's not any more expensive to just build a 2.4. But I wouldn't go more than .020 on a 2.4 block, there's been more than a few cases of cracked cylinders, like Momin's. You can bore the hell out of a 2.0, .060 is not unheard of.
