I would like to share some pictures of my Hyundai G4CP (aka Korean 4g63) build currently running on my Colt, as some of you know they are 6 Bolt and I have been using this engine since July 2013, I finally found these pictures because I had them lost then I found them and here they are, it seems to hold the abuse pretty well (ran 14.6X with no tune), I thought this info could be useful...
The engine came from a 1998 Hyundai Sonata with 134k miles, I did my own research before throw it on the Colt and found out that Crank, Rods, Main Caps and Bearings are the same of the 6 Bolt Turbo
Everything looks like a 6Bolt Turbo except for no oil squirters
The timing belt tensioner its like the 7Bolt style
Since its a OBD2 engine it comes with Crank Sensor on the crank case (oil pump), but watch out because this pump may look like the 7 Bolt found on 2G DSMs but it's different, it won't fit either on a 6Bolt Turbo Block or 7 Bolt, so it's a unique design for OBD2 G4CP Blocks
As you can see these blocks don't come with a Knock sensor location, so I had to make a hole and thread for it...

Since this crank case has a round shape right on the middle the engine oil pan both of the turbo oil pans won't fit, so you have to run the G4CP oil pan, then in order to run a return line I drilled the holes for the oem return line and welded some nuts...
Now the question that you guys were thinking, Which pistons I left on the block?? Well I just throw a set of stock 6 Bolt Turbo pistons and rods
Next thing that I thought that would be good to run was a oil cooler because the stock oil filter adapter from the G4CP it's non cooled, I went with a OEM water oil cooler I guess it's better than nothing, well the 6 bolt oil filter adapters won't fit in the crank case but 7 Bolt was a little bit closer, so this is what I did:
Here is a 7 Bolt oil filter adapter with the G4CP oil filter adapter gasket, the yellow section it's what I had to drill in order to make it fit
Here is the engine fully assembled
Cylinder Head it's Hyundai as well, Intake manifold it's from a 94' Galant GS , cams are Hyundai too, I haven't replace them yet for turbo ones...
