OK, I was going to hold on to this and use it for my autocross del Sol build, but since my class requires natural aspiration, and I'm only looking for 200hp, this block is overkill. The block is the B16 out of my 94 del Sol VTEC. Here are some details on the block: Balanced stock crankshaft Prodrive oil pump with hardened, clearanced gears New water pump 81.5 mm bore The block does not have pistons or rods, so I'll leave those up to you. This block can take a bunch of horsepower, and would be a great base for a turbo/supercharger build-up. In fact, it made 453whp on a dyno pull, testing a head/turbo combination. Besides the dyno pull, it has not seen any hours after the sleeves were installed. There is over $800 in the sleeves/isntallation alone, not including the price of the block and the machine work. Please PM me your e-mail address and I can send pics. Asking $1,000 obo. Would also consider partial trade for a B16A3 longblock.
