if its heavier wouldn't it put more load on the front tires and still have more power to weight then a B16 stock?
since most people here care about straight line i don't see a downfall except maybe the trans, but you can change gears out, mario's H22 EG is quick as hell, and his frankenstein was even crazier
plus the type-s cam is perfect for turbo, you don't need to get different cams, and with the new...ish mahle gold pistons you don't have to resleeve
i'd say go for it, you already have the common car, go for the uncommon swap, besides, you can stroke to 2.6 too
