Okay i am a bit confused here. I saw an engine block which had this number: 4G63TR4662. By this number, it means that its a 4G63 Turbo. What would R mean? I tried searching for it but did not get anything. Is R some random series of the block or is it to specifically identify something, perhaps in which car the company gave it in? Also, if it is a turbo block, why would it have flat shaped pistons, higher compression, rather then dish shaped lower compression pistons. The pistons were standard factory pistons. The oil pan was also one of NA engine, no hole for the turbo return line. The guy said it had a 2g head with N/A 4g63 Exhaust Manifold. He did not know which car was it from. Any ideas what block this might be? NA or Turbo?
