You cannot use diesil turbos on a draw though operation, (carb in font of impeller) as the fuel will react with the seals giving a vacume and/or an oil leak. As tech says you need to do a LOT of reasearch before buying a turbo or turbo kit as it gets finiky and pernekity in a real hurry ! By this I mean reading impeler pressure maps and turbo A/R ratios.
