theakerstwo Posted December 21, 2012 Share Posted December 21, 2012 My friend John had the stock E9 turbo rebuilt and re-worked at the same time, and he said the reworked made more boost than the holset and out performed it. He advanced his pump timing 3 degrees and tuned the pump up as much as it would allow. Hs said he could pull Mt. Eagle ( from a get on ramp at the bottom) 92,000lbs. and top it at 75 mph while passing 2 junk Petes ( that where empty).He put on many heads due to loose valve seats, from getting them to hot the day before. He put on a set of Dale Francis heads and never had a problem again. 6.5 mpg and tons of power. Even the 865 and 866 engines had valve seats that would come loose.
