And you are also correct that going thru all this work to only go from 130 HP to 150 HP doesn't make much sense either. There are many other easier ways to obtain HP gains with the Delorean engine. I undertook this project simply to gain some knowledge about the differences between some of the various PRV engine configurations which were produced. I'd heard stories, as many of us had, about swapping these various engines and parts and stuff, but it was all speculation from people who had never actually done it, only talked about it. Since I had the engines available, I figured the best way to find out for sure was to tear into things and see what we actually had. Like I said before, I'm really amazed at the differences between these engines. My understanding of the original intent with the PRV was to share design basics and, you would assume, share as many parts as possible for cost effectiveness. I guess, just like with many projects, things didn't work out exactly as they originally intended. The designs and parts are similar, but not interchangeable. I now know this as a fact, because I've had the parts in my own hands and have been able to make the comparisons. I now know what will work, what may work, and what won't. Like we said before, you are correct, there are many more "cost effective" ways of increasing the HP in the Delorean engine compartment. But for me, my interest is in staying with the original basis of the PRV engine, only increasing it's performance level (and I'm not just talking about 20 HP either). This project has allowed me to look into alternative methods to try and realize these performance increases. I've gained a lot of information from working with these engines, all of which is being utilized to build my "new" PRV engine. We'll just have to wait and see what I end up with :-) Marty
