Rod journals are different between 20v and 20v. I would basically put 20v internals in a 20v block

Also lighter and less rotating mass

current:
-mk4 tdi wagon with some mods
-TDI b3 90q, holset turbo, be strong little connecting rods!
-the turbo tractor
past:
-11 second 90q junker
-20vt swapped 90q winter beater
-efi 20vt 4kq
-way too many other long gone urs's, 200's 4000's, b5's

Yeah the mains are the same. I need to figure chamber CC of an AAN piston or head chamber to figure what what combo will work. The 9:1 3B pistons may be better suited. If final compression resulted in 10.0 - 10.5:1 I would be happy

So going through with all of the hybrid 20v pieces to build the ultimate 20v is basically out of spite? Will be watching ;)

PKW had the mc block and pistons shaved 4mm for a ghetto 20vt. Maybe you could have the mc block decked 8 mm and run the AAN pistons. You probably would have to machine some new valve reliefs and maybe you could get some wrist pin bushings to fit the MC rods but with a 20mm bore???

Wow this car hates me. I got a good 20vt MM hose from a friend that I'm borrowing for diagnostic purposes (current hose has a hole) and as soon as I went to drive it, I heard an electical "pop" and everything died. I lost ALL power completely. Nothing would reset, nothing worked, EXCEPT, the AMP lights were on meaning they were getting the signal from the head unit....even though it was off???????

This would have been fine if I wasnt at the bottom of a hill with a dead phone. I had to push the car back up the hill with the dodge and back into the garage......oh fun shit.

I think my power distribution block took a shit or something because the battery has plenty of power and if I hook jumpers up to the block, everything will work again until I take the jumpers off the power block

The good news is I now have a medium-duty drill press LOL
