Keep in mind that all the prices above are brand new prices and high dollar parts and brands. A nice used turbo can be had for around 800$, xo2 or vs racing wastegates work fine and are only 200$ shipped and they now have a descent blow-off valve too. When I bought my carb I got a dual needle and seat CSU for 900 shipped that had omly a few passes on it. Or you can do the conversion yourself for next to nothing. And hats are 150$ from csu no need for them high dollar EV hats. You would prob. have no need for a high dollar elec. boost controller, you can get a manual turbo smart for 100$ All I'm saying is it can be done alot cheaper than parts above.
