I bought an 89 rex with some about 221000 miles off eBay. The engine runs all right… But for you stock Rex HF owners out there you know that it has little if no power… The D15b6 in it is a great engine if you like getting 40 mpg. We all love the 40 mpg but the lack of power is frustrating to say the least. So I have come to the conclusion that a swap is needed and would be best. Now the problem I am having is choosing what engine to drop in. Some of my friends say that a b16a would be a nice engine to put in. My crazy friend that’s Integra crazed says drop an LSvtec in. I know that the b16a would fit nicely and would be formidable engine. I was told if I put the b16a in a turbo would be a good idea. But I'm told that a properly built frank would fit snugly in and be an all motor monster that in the least should be respected. I’m not to sure on prices of the engines as well. I know that I would want to build the engines myself so I’m also looking for price ranges for both. Any help would be great and much appreciated.
