I can remember it took me a long time to get all of the components, but I don't remember ever changing the configs around. I do know there are more than 4 33s on the DLS - there are over 20 if you include all the variations (33/0, 33/1, 33/2)!
Take another look to make sure you have all of the dependencies, because that was what was wrong when I had the problem. The way around that I eventually did was to download all of the uploads by zxr400, then one of them must have been missing.
I've just looked back at the first post, and the enginespec, as mentioned in my last post, is class_33_engine,<kuid2:51536:51003:3>.
