It isn't like it is that hard to remove the cam in these motors. Time consuming? Certainly.

15,000 miles is 5 oil changes (assuming 3000 miles between oil changes)

My daily commute comes out to about 9600miles per year, even with another couple thousand miles driving around for fun I'd have a hard time reaching 15K miles in a year. So maybe 1.5 years between re-shimming. Doesn't seem all that bad to me.

Besides, you can always check clearances every other oil change just to track the wear rate, in case it comes sooner than 15,000 or goes longer, etc.

So the Piper sets don't come with the shims? So, where do you get them from? ...And what do you ask for?

"What car's it for, sir?"

"er... Porsche 924"

"No, that has screw-in adjusters"

"But I've fitted Piper solid lifters"

"Sorry, sir, don't know what you're talking about. Next!"


Plus, if the valve adjustment has to be done to 0.05 mm, what good are shims in 1 mm step sizes...?

Yes, Piper can supply the shims if you want them, or you can get them from any competent machine shop, which we have plenty of here in Detroit. Although in my case the head is going to European Motorworks any way for full prep, so they are providing the shims. Part of my valve train lightening process.

It's called machining, again, something any competent machine shop can do.

Well, when you consider the solid lifters themselves cost less than HALF that of new OEM lifters from Porsche, it's not so bad. Furthermore, if I were just building a stock street car, it may not be worth the cost and effort. But in my case, I'm building a "maximum effort" motor, so I felt it was well worth the trouble. And btw, European Motorworks is not charging me anything more to do the solid lifters than they would have for a stock rebuild. When the machine shop is doing the work anyway, and they're equipped to do it, it's not really that bad. Doing it yourself would be a royal PITA. Solid lifters aren't for everyone.

Gotcha - I can seee that if it's all done at the same shop, then cost increment could be very small.

Cheers

Mike,

Shims are very easy to get. The people who do my head work supply and machine them as part of the job. Any decent engine shop can cover this.

Looking for some solid cam followers. Who do I contact, Piper in UK?

Are the FOLPOR the only alternative?

I am building a new engine this winter. The head has been rebuilt and ported. A 268° turbocam, new springs and an adjustable vernier. The idea of putting 30 year old stock followers doesn´t feel right, especially since this baby will rev to 7000rpms

OT:
Bottom end: Crank and rods are lightened, polished and balanced. VW forged flat-top pistons. MLS gasket and ARP bolts.
Clutch: Billet lightened flywheel, 930 clutch and 911 RSR pressureplate.
Turbo: Either GTS K26, 951 K27/K26 hybrid or 956 K27/k26.
Intercooler: Either GT or 951.
Ignition and fuel: Modified 931 S2.

But to answer your question, I agree that they are ok in a stock engine - solids are overkill.

Jeez, need to hand feed you guys...

Main site: http://www.newman-cams.com/index.html
Porsche catalogue: http://www.newman-cams.com/pdf/porsche.pdf

I'm sure you can figure the rest out yourselves...

Oh, and I should mention that RC was never able to get any responses from them, but I didn't have any trouble as you can see - YMMV...

Finally, I was thinking about grabbing another set (to add to my growing pile of "just in case" bits). So maybe we can get a reduced shipping price from them. Happy to facilitate that.
