That's a really nice looking setup - is that soundproofing making a noticeable difference?
Hard to tell because my baseline is pre-engine conversion (Td5 to 4BD1T), but it is no noisier in the cab than before and the 4BD1 is a far less 'refined' engine. According to my Android sound meter app the average volume cruising is 78db. I don't have any under bonnet insulation yet, doors are untouched and the firewall only got a mild treatment as it will be swapped out for a galv unit when I paint the truck. All the sound proofing is from retail suppliers like Car Builders or Dynamat, I'm going to add some premium materials (denser & thicker) when time and motivation permits.
