I am currently rebuilding my 2.3T, and I was wondering if these pistons are good or not... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7981453907&category=33623 Should I buy in a autopart like napa, or ebay is okay?
Flat top forged pistons were stock on the 79-81 carb turbo 2.3L's. You would need to check the compression height. Dished pistons would be better but you could drop the compression a bit by opeing up the compression chamber and unshrouding the valves.
Ideally you want to lower the compression ratio to improve volumetric cylinder filling. I think you can get forged dish turbo pistons from Race Walsh but I dont have a current catalog.
Just for reference, you can get stock replacement forged turbo pistons from autozone for like 40 bux each...maybe 35. They are speed-pro brand.
