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 |

Personally, on an engine that would be expected to be reliable in the long run, I'd still avoid 103's except for nickies. Even with Nickies I still don't like how thin the skirts are with 103's, on my '67 beetle big T4 engine I'm running 102mm JE's. For the biral's I'd stick to the 98's offered by aircooled(dot)net. John at aircooled is a good guy and they for sure put some extra effort in the P&C sets they sell. If you look at the price of buying piston's alone it doesn't make sense to buy the components separately. It costs more but they run JE slugs, if I was cheaping out on Nickies I would still pay the price and buy aircooled(dot)net's P&C set. http://vwparts.aircooled.net/Piston-Cylind...9800t4sb-je.htm http://vwparts.aircooled.net/Piston-Cylind...w9800t4b-je.htm |
