I am putting a 4bt in an 81 f150 and I was wanting to know which turbo would be a good choice for me. The engine is non-intercooled and I plan on keeping it that way for a while at least. My build is mainly for economy and streetablilty. The turbo it came with is an h1c but needs rebuilding or I would like to go with an HX30 or Super HX30 (Genuine Holset new or Rebuilt). Any suggestions? Thanks!
