    Kevin, Lifters that run against the cam lobe should always be resurfaced or replaced, as in the EA81 engine. The followers that run against overhead camshafts should be inspected to make sure the following surface is free from wear.

    The EA82 and EJ22 engines have nearly bullet proof cams and rockers and usually don't need replacing. We will inspect and resurface, if necessary, any rocker sent to us. Thanks, Jerry @ Delta Cams

     

    "1. Always use new lifters when installing a new camshaft. The bottoms of the lifters are spherically convex ground, and the cam lobes are ground with taper. The mating of these two surfaces ensures that the lifter will rotate, thus reducing the chance of premature wear. If you install used lifters on a new or reground camshaft, early failure is almost certain."

     

    That last part in bold is what bothered me. Everything on my XT6 is almost certain to fail. Fortunately, it seems people here haven't had a lot (or any) problems with their new cam grind. Unfortunately, I wouldn't fit in the same category as there are no XT6 cam grinds available....yet. I just need balls big enough to be the guinea pig. *Thinking* ........*shaking*

  2. I'll bet on disc brakes, after I did a rear disc conversion on one of my cars, the rusty discs never did clear up until after I had them turned. Like you said a soft scraping noise when slowly coming to a stop, check the discs in the front, and in the rear if you did the conversion. Did the vehicle set for a few months? If it did, this is a definite possibility.

    Above page is very crude maps and turbo data, the B series has been replaced by the F series turbos. This will give you a general idea of application.

    This page has some sourcing data from junk yards, along with some HP estimates for the diferent series of turbos. IHI data is hard to come by, and not very detailed from what I have found.
