I'm rebuilding a 3L turbo and I'm having trouble figuring out when my engine was built for the rebuild kit. The cast numbers on the block, heads, and pistons look like:

Block
5Y271
VG52

Heads
L-V52 5L
R-V52 1L

Pistons
902-1 16E-2
902-1 16E-1

If anyone knows where I can find more information on casting numbers or where to look for them on the block it would be a big help. Right now I'm at a stand still.

 

This might help.........
If it doesn't .........

They should have a decently priced VG30e/et for you.
I did try to rebuild my V-6, but it turned out to be much cheaper
buying a full motor.
