Hydraulic cam followers

[Jake Raby]

Now for the funny part.. When approaching INA at the International Motorsport Show a few months ago, they denied ever building this lifter, or even having a part number for it.

Be less concerned with the hydraulic properties, and more concerned with the physical properties of the lifter crown. The surface finish also matters, especially during break in/ work hardening. I have seen some of the replacement lifters that literally had a surface that was achieved with a scotchbrite wheel. Thats what you'll get when you pay for a cheap lifter, and its no way to achieve a proper roughness average.

I get calls about this all the time. The quickest way to cost yourself thousands of dollars is by trying to save a couple hundred. We call it "Stupidity tax" around here, and it gets paid a lot.

This is worthy of a signature quote. There is nothing more true. On cars as highly engineered and constructed as Porsches, I rarely consider anything other than OE Porsche parts, especially for critical areas such as drive train or suspension. Exceptions are parts developed by reputable vendors and used with good results over long periods of time, or Audi/VW parts that are often the same but labled with different part numbers. Unless a part is NLA, there are few reasons to deviate from spec. Remember, you don't have to purchase from dealers. You can get the real stuff from good vendors, like Pelican, and others at great prices (in the 928 world, we have exceptional vendors, including 928RUs, Roger Tyson, who has also supplied me with Boxster parts).
