it depends on how much the motor/tranny was and how good you actually are at custom fabbing stuff, because nearly every single thing on that swap will have to be custom. its not a common swap..................ive never actaully seen it done, yet that doesnt mean it hasnt been.
i think you will benefit more in the long run money wise and performance wise to just turbo the d or look into a different swap..............like b or h series. i personally would just turbo the d because it is cheaper and you will most likely be quicker.
you need to look at aftermarket selection also. i dont think the aftermarket is as heavy for the v6 accord motors, therefor you will probably end up paying ALOT more for any given part that you want to upgrade.
