Oh, and any advise on what would be a good/cheap turbo for a 2.4litre nissan would be much appreciated. Is a factory turbo, secondhand, removed for an upgrade, going to be better quality and fine for my situation, or are the $150-$250 new, ebay, made in china turbos actually ok to use? I have a lot of experience rebuilding and working on cars and motorbikes and my father taught me a lot of his 50+years of experience working on english sports cars, but he and i both have zero experience with efi, or turbos. Got a ton of su carbys for a suck through setup though! I'm guessing blow through would be better. any advise would be appreciated.
