$350 4g64 5 speed swap project started
Okay so here's the story. I've been driving my 8g since 2002 when I was 16. It's a 1999 Galant ES automatic 6g72. I bought it with 41k miles on it and it now has 223k. Whatever happens to this car, I won't let it die. It's a sentimental thing at this point so I'm not giving up on it. So about 2 months ago the engine overheated bad and it quit running. I started driving my other car instead and kinda forgot about the galant and let it sit. Well I sold my other car so now it's time to get the galant going. I knew it overheated and the heads were probably warped due to the fact that it could still run but combustion pressure was coming out of the overflow bottle. So first thing was to pull the heads and see if maybe I got lucky and it was just head gaskets. No luck, .013" warpage on the heads

I've started redoing the surface of the heads and have one down to .06-.07" warpage, which is actually within the spec of .08". I decided a while ago tho that the 4g64 was a better option. Easier to work on, seemingly less problematic, and more options and potential when it comes to making power. So the idea of a 6g72 to 4g64 swap was born. I also have wanted to do a 5 speed swap, and since this automatic is shuddering and struggling to hold a gear, now is a good time to swap transmissions. So I searched for a 3g eclipse with a 4g64 and 5 speed. Just when I thought I would never find one around here for cheap enough, a 2001 3g pops up on Craigslist.

Owner told me it doesn't run because the belts are bad. I figured that meant a thrown timing belt, so I was able to talk them down to $350 for the car. I found the shredded timing belt in the back seat after I got it to the shop. The car is trashed. The body is faking off and interior gutted, but I don't need that stuff anyways. I'll scrap the car when I'm done. Since the timing belt went, it's time to pull the head and check the damage

I honestly don't think the pistons hit the valves. I'll take the cam out of the head tomorrow and check the combustion chambers for leaks, which will tell me if any valves are bent. I'll also check deck height and see if rods are bent. I can then the crank by hand, so the pistons aren't seized. But the oil pump and balance shaft won't turn. Top left and bottom right gears in the picture are stuck

Tomorrow I will pull the oil pump cover off and see what I can find. Once this engine is running in the 3g, then I'll swap it to the 8g. That way I know it was good before the swap and if it doesn't run afterwards, it's something I did wrong. I'll post pictures of everything as I go. I figure I'll do a full prothane kit for bushings and mounts while everything is out. Probably a clutch too. I think I'll leave everything else stock for now until it's good. Unless the valves are bent in the head, then I might as well do a DOHC swap right now.
