don't forget aftermarket sleeves, b/c i wouldn't dare bore the stock block out 3mm.

If you use the 89mm b20/ls crank and rods with 82mm pistons you'd have almost a 1.9L

defentally need to find a good person to do all the machine work.

If you are going to bore, you can also give GSR block a try.

Or take a B20 short block, bore out 1mm, and use ITR crank and rod. You will also end up with a 2 liter engine, as speficied on Toda website.

personally, i wouldn't over bore a b-series block more than 1mm (so thats 82mm).

Boring your sleeves will result in just as weak cylider walls
you need to resleeve to have a strong 2l block.
Send your block to GE, or benson. But its not cheap to build a motor.
