Message: [QUOTE="Drkhrse, post: 1528016, member: 31352"] Stock everything ... bought used withj 94K miles... 2 years ago while a mechanic was working on it chasing a rattling sound - it ran away.. He refused to do anything about it... He was chasing an oil leak in the Turbo and kept running it for about 20 minutes trying to see what he could find (Leaking Turbo Oil Seals and pressurized air blowing it TOWARDS the intake!!! DOH.. Even offered to sell me a new 5.9 to build and change to a Cummins with the adapter kits...If he wasn't armed..... I spent 3 months rebuilding the thing. ARP bolts and studs everywhere they made them for (Girdle, Connecting Rods, Heads, Flex Plate and Balancer) Got the cartridges for the Turbos .. Used an H&S programmer... ran good for months but I went up an entrance ramp at WOT and lifted off the throttle and POP... Head gasket was blown.. getting gas back into the Cooling system from the back-pressure I guess ... New (more reliable and knowledgeable) mechanic fire-ringed the heads - said if I went large single it would be a beast... the problem is, I think the Turbo Kit 69/73 SXE has a cheap turbo as well. Casting doesn't have intelligible markings .. The H&S site has a write-up on the new SXE turbos and the .91 twin scroll and low throttle... If I was seeing reasonable drive-ability.... 1st thing is check to see if the housing isn't "tight" enough and allowing too much exhaust to bypass Turbine wheel... After that, it's bite the bullet I guess for a 66 [/QUOTE]
