I have an '87 Turbo Supra that's about to get a new engine. I'd rather go with a new turbo instead of a rebuilt one. Which turbo upgrade should I go with? Definitely looking for more power. I'm also going with a 3" downpipe/exhaust system. Definitely need advice on which turbo to go with.Also what other initial upgrades should I go with? I'm open to all suggestions!
