Considering a turbo upgrade for your Mitsubishi 3000GT? It’s a powerful enhancement, but understanding the parts involved and their costs is crucial. Before diving in, recognize that upgrading your 3000GT with a turbo can be a significant investment. For instance, just the pistons and turbo alone can quickly reach $1600. If you’re on a tight budget, especially with limited savings, it might be wiser to explore initial bolt-on modifications like intake, headers, exhaust (I/H/E) and ECU tuning (ecuflash) first. However, if you’re serious about forced induction, here’s a breakdown of essential 3000GT parts for a turbo conversion, helping you assess the feasibility of your project.
