Piston/Cylinders, Are they built well? Options

[davidj]

I was lurking around today for some piston/Cylinder kits and came across these and wanted to know if they were good for a "Street Performance" engine. I do know that these are less expensive then the Nickeys. But still could be a good product.

103mm Aluminum Alloy, NiCaSil-coated cylinder From European Motorworks $735.00

And then came across these from AA. And was wondering if these are better then the stock cast iron type?

96MM ALUMINUM BIRAL CAST IRON PISTON/CYLINDER KIT $385.95

If anyone has any experience with these I would apreciate it to hear from you.

Thanx, Dave

"Birals" have iron liners and alloy fins. They are NOT to be confused with either "Alusil" or "Nikasil" piston/cylinder sets. It's old technology, used by Porsche (and, I'm sure, others) in the 50s and 60s.

What I'd like to know, are these (Birals) a better choice then the all iron type? (IMG:style_emoticons/default/beerchug.gif)

Aluminum does a much better job of shedding heat than pure cast iron does...so they do that much better..
the core cylinder is still the same..its iron with no fancy coating to have issues with.

Its also 356 technology..which has been replaced my the nickasil or alusil units a long time ago....

I'm at home today and can't look it up, but I think they used Biral until the 2.2 engines, and maybe the 2.4s.. ol, yes, but it's still viable technology. BTW, I think it was also used in aircraft engines, but I could be wrong.
