[QUOTE="d_daffron, post: 726236, member: 4983"] So the original tech stuff is all good, were only 3 rides in on it the biggest failure was that slip yoke driveshaft which only "saved" me $50 originally. I wouldnt say that I wouldnt do it again but I'd certainly do a spark test to make sure it was steel before I tried that again. I'll try to list things that didnt save me money. $100 80lb Ebay injectors = fail They would not operate at low pulse widths which drownded the engine in fuel at idle so I pulled them out and put in a set of quality rebuilt Bosch's $20 ebay fans = fail So I bought two 14" electric fans off ebay, complete waste of money. With the fans on high you could barely feel any air moving so I pulled them off and installed a set of stock honda fans now you can feel a breeze standing 5' behind the buggy Ebay 2 bar map sensor = fail I dont know what I paid for it but That cheap map sensor worked for about an hour before it got stuck on 100kpa and shut the engine down. I replaced that with a parts store "wells" brand and fixed that. Corvette internal regulated fuel filter = fail I'm running a 300lb/hr fuel pump because I thought I'd need E85 to get thing to live at 10:1 compression and boost. So far it seems okay running 93 probably due to the efficient chambers and small bore. You cannot run one of those internal regulated filters with a high flow pump because it cannot regulate the flow. I ended up with 80+ psi fuel pressure so I didnt even get to start it before I took that stuff off and went with a regular style fuel filter and regulator. [/QUOTE]
