adding piston cooling.

[mazdajack]

Hello, 

I have a 1982 mazda b2200. I know at some point i'm going to have to do a rebuild. When I do I would like to somehow make a modification to add piston cooling. From what i've researched the perkins 4.135 for marine applications, the perkins 4.152, and the the Westereke w52 all have piston cooling. Would it be possible to create a hybrid engine, my using the pistons, connecting rods, or even the head off of one of these other engines to add piston cooling to my engine? Which one of these components would I need, and what is the best engine to try and source it from? If the piston cooling  effect is created by channels in the block that create oil jets, I probably wouldn't put a different block in my truck. But if the modification would be a question of putting in different pistons or connecting robs then I would consider it if i can find the parts. Thanks in advance for your advice.

Why is this needed? If you're adding a turbo charger a pre turbo EGT gauge would give you the info needed to not melt your pistons.

you would need the marine rods and pistons. they will lower your compression slightly, not enough for you to notice. still rated at 21:1 compression.
using piston cooling helps prevent pistons expanding excessively. which reduces engine wear. as marine engines are under constant load, motor vehicles are lightly loaded until going up hill or accelerating.
