The head bolts up fine. The block casting is identicle to the h22a vtec motor. This means you don't need an external oil line for vtec. The wiring is easy, just three wires. I'm not sure if the valve reliefs are deep/wide enough for the vtec valve throw. If the h23 intake valve head is the same diameter as the h22a vtec valve head then you should be fine with the stock pistons. Upgrading the pistons and rod bolts would be a good idea.


If it was me I would just swap a jdm h22a longblock instead of the headswap and then sell the h23 longblock. These setups don't seem to be as successful as lsvtecs.
