Calling all gurus...block identification

[DSM pHrEaK]

Alright here's what's going down. I've got a 6 bolt non-turbo block that i had bored, tanked, etc. I've got the crank bolted in, pistons in, rods bolted to crank. Put the head on last night. Then moved onto installing the front case and noticed there was a couple of bolt holes that were not lining up. I went to one of the turbo blocks i had laying around and compared and what i found was very odd:

This is a picture of the turbo bottom end:

You notice that the oil transfer port from the oil pump to the oil filter housing is shaped slightly different, and when lining the turbo front case up on that block the cutout on the case doesn't match the port on the block. Then the big bolt hole (the one bolt on the case that's a 14 head) does not even begin to line up?

Anyone on here have even the slightest clue as to what's up? I've never known for the cases to be different between a turbo block and a non-turbo block?

Is it a 95+ hyundai block? They take a different front case with a crank sensor, usually used for a 6-bolt swaps. Take some more pics, and include the block code.

Based on the spacing of the OFH bolts and assuming they are both originally DSM engines:

Top one is a 6-bolt. Bottom one is a 7-bolt.

Ok so if this is a g4cp block I'm still good for putting it in a 1g right? Just need to locate a front case. Is the timing tensioner the same or are they different as well? I'ma do some research. I'll look for a casting number and get back with you guys

I checked out the block more closely and it has "G4CP" cast into it. Are there any advantages to this block compared to other 4g63 blocks? Apart from simplifying a 6bolt swap in a 2g?

It's only an advantage for the 2g guys doing swaps. As long as you have the front case, and ofh for it, it shouldn't have any other issues. I would however check for mounting holes for the front and rear mount brackets.

Alright, I'm having quite an issue trying to find the correct oil pump for this block. Half of the pumps online that say for "G4CP" are not the correct pump because they do not have the same oil ports. I stumbled across the pumps for the evo Vs and VIs and they look closer, seem to have the same oil ports, but don't say their for the g4cp??? Does anyone know of anywhere I could possibly find the correct pump for this thing?

Or if there's a reliable way to modify the pump i got?....Anyone?

For the non-turbo bottom end (the block in the bottom picture), it looks like NAPA part #SEP 22443603 or RockAuto part #22443603, which is for '96-'98 Hyundai Sonatas with the 2.0L engine.
