I have a 90 300zx z32 (Non Turbo) with engine problems, sound like rod noise (180K miles). Any suggestions on best way to go, either rebuild (keep numbers matching) or go for a rebuilt crate engine? I live in Delaware and I'm looking for someone local that could possibly rebuild it for me. So far I found a company PrecisionEngine.com in Houstin Tx that will rebuild it for me if I ship it to them for about $2,700, comes with a 3 year 36K warranty. Anyone heard of Precision Engine? Thanks for any help here!
