I am getting going to get ready to put a 2056 FI engine together for a daily driver. Trying to decide if the cost is worth the difference. Biral are supposed to run 20 % cooler. Porsche used them for a couple of years and moved on to coatings.

I've done this exactly once, so no expertise here, but I spent the first 2 years of my restoration project and engine rebuild reading, talking to people and researching.
The general consensus was that AA was inconsistent on quality, often out of round, chinese knockoff crap, and birals were a fad, and would likely not provide the same level of reliability and problem free performance as the cast iron over the life of the engine. Nikkies (spelling?) are the best way to go, but are very expensive. The BEST way to go is to use the stock OEM cast iron cyls honed to your size if possible. Talk to the guys at EMW, they have data sheets showing the quality and metallurgy/hardness characteristics of their cyls. I went with KB pistons and new Cyls from EMW, couldn't be happier..... |
