Nickies?, Are these the real deal or just a cheap knock off? Options

Has anyone got these? Sounds to good to be true. I sure can use these shugaboogas! (IMG:style_emoticons/default/beer.gif)

Take along a GOOD bore gauge and a GOOD magnifying glass to see where and if the chrome plating is flaking at the top and bottom of the cylinders.
I like the Sunnen bore gauge my self.

And be willing to MAKE THEM open up a bunch of boxes of cylinders until one set meets your expectations.

This assumes you know what to look for in a nicasil style cylinder.

Cause ya can't machine them once bought. Machining the length will cut into the chrome and make it flake off at the open ends of the cylinder. In essence. you build the engine around the length of the cylinder.

THEN you have to have your after market piston manufacturer make you a custom set of pistons to a 911 spec to be compatible with these cylinders.
Aluminum cylinders take a very different piston profile that a cast iron cylinder to be correct. Unless QSC now sells pistons to match their cylinders these days.

THEN you have to know what torque specification to clamp them down with. Cause these ain't cast iron cylinders and the expansion rate and expansion length is vastly different from a stock cylinder. Hence different torque values.

And you will also have to source a ring pack from your piston supplier that is compatible with a chrome lined bore.

The Chicom pistons they sell with some of their cylinder kits flat don't work for ANY performance engine.(Tin coated shit)

If your into experimenting and you have the resources to do that... head on.
Odds are... it may not work well first time out.

They are fun to play with. Just expensive as hell until you have the learning curve down.

How much R&D are you willing to do...???????

Just something to think about.

Now back to my hole.........
