I know I got my valvecover, oil pan, rear main seal holder, oil pump and timing parts off of a 1.8L Hyundai Motor. It has bridged mains too. Not sure of the details on it though. I imagine its pretty similar as far is the head is concerned. I didnt measure valves or anything.

Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.

The head the same as a 1G mitsu, big ports and all.

I wonder if valve springs or heights are different.

I have a 1.6 long block and intake manifold...the intake looks just like a 1g turbo intake manifold, so i might have that one modded for my swap!! The head also looks the same, but im sure the cams,springs..etc are diff from a turbo 2.0!! :wink:
There is always someone faster!!!

just put in some VR4 cams everything else is the same, the corporate sharing of the mitsu engine gave hyundui all the 1G head engines where mitsu went to the smaller port 2g. i have 1800 and 2000 cc hyundui engines here and you can buy them for next to nothing. turbo mitsu's have lower comp pistons.

My brother just bought a 95 Sonata. It has a 4G63 and everything is identical to the 1G on the exterior. Except the Hyundai motor has a nicer looking valve cover. (I might steal it) I'll check to see what bottom end it has. I'd like to find out if Hyundai used the 7-bolt on this. I'm sure you can pick these cars up for nothing. He paid $200 with a broken timing belt. $500 and you have a perfect car. (assuming it was taken care of) I'll let everyone know as soon as we pull the head and order parts.

Pretty sure all Hyndais, including the ones built after 93 were all still 6 bolts. Not 100%, but that's what I've heard.

Did you ever find out if the 93 and up Hyundai 4g63s were 7 bolts like the Mitsubishi versions, or stayed 6 bolt.

on the DSM 4G63, you could check by looking at the timing belt side of the oil pan. If it caves in, in the center, then it is a 6 bolt, if it is flat acroos that side it is a 7 bolt. Wonder if that engine is the same -- anyone else ever hear of this?
