Sorry, i meant get either b18a/b block, and bolt the right head on. It doesn't cost less to do an obd0 ls/vtec swap compared to the b16 swap. You have to do a couple things to make the engine and head combo more reliable. The ls block was never meant for vtec, therefore creating the need for more maintenance and building compared to the b16. That's from what I read...
You don't need a shitload of torque for a crx or civic hatch to be fast. Yes, torque will help, but these cars are light to begin with. If you want that extra torque boost, get a turbo, or even nitrous... I honestly think those two methods, with proper maintenance and care, could be more reliable than an ls/vtec frankenstein swap. Just my 2 cents.
