I currently have 2 honda engines. the first is a stock Zc vtec and the second is a sohc zc non vtec that is also stock. which block is stronger or worth building up. i want it to handle 250hp at the wheels. ill be using a td05 dsm turbo and building one or the other blocks with oem bearing, tt rods, and vitaras. should i put the vtec head on the non vtec block and build it, or just build up the zc vtec??
