Help! got a hole in my block!
Got a 1988 4x4 truck. Original 22RE has a "laser" block. Replacement block has three holes in the "bowtie" casting. Two threaded bolt holes on either side of a larger, unthreaded hole straight through to the crankcase.
What was this for?! Original is just a blank in the casting. Thanks

You could make a block-off plate and seal it good to the block.
You will have another issue though if the new block has the crank and pistons installed: the turbo engine has a lower compression ratio than the stock 22re so you'll be down on power.

Set up as a turbo, yeah, kind of rare. But no significant differences between the turbo and n/a blocks. Deck heights are the same... on and on. The pistons set the compression ratio.
A good machine shop can take a regular R/RE block and machine it for the turbo return and stuff, and with correct internals, make it run a turbo with no issues.
If it was recently rebuilt, you need to find out information about it- like whether it was rebuilt for turbo or non-turbo use.
