Definitely worth taking the opportunity to forge the engine, ultimately decision is yours but with second hand engines being qwestonable hereI'd hate to think of the availability in the us. If you wanna do something a bit different find an sr20ve engine, they are readily available in the us and fit the head to your det block. It's what I'd of done if I could've found one over here but alas I'd of had to import from America
