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 have heard of earlier low-cost birals having slippage issues. I dont' know if it was AA, though.
I don't think I'd bother for a street-driven 2056, myself. Cast-iron has proven itself for that config over and over again. --DD |

I don't think I'd bother for a street-driven 2056, myself. Cast-iron has proven itself for that config over and over again. (IMG:style_emoticons/default/agree.gif) Head temps are the main concern, not cylinders. Look at a 911 engine for example, the fins are not as deep as a VW cylinder. FWIW, I have built many engines using AA cylinders. My 2270 is 20 years old now with who knows how many miles and has cast iron 96mm AA cylinders with KB pistons. |
