i know that there is a hyundai that has a motor that looks like a 4g63, i also know someone that has a second gen eclipse turbo. i asked him about mods cuz he claims 800+hp. he said it has a hyundai head, said they flow better than the eclipse head. im helpin a buddy build a 1g tsi and we are tryin to figure out head options and i was wonderin if that was true.

 

The head is the same as yours. Hyundai head does not flow no better. Its the same as a 2g head.

 

800 HP in DSM?


I want pics.

 

The Hyundai head is the same as the DSM head? Weird.

 

The older hyundai motors were DSM motors with a different valves cover...

 

arnt the 1g heads better then the 2g heads? yes 800 hp in a dsm is possible i dont have pics of that perticular car but i do have pics of a talon with that much or more. and i have pictures of a 96 mitsubishi mirage with like a 6 or 800 hp 4g63

 

The only real benefit to using the Hyundai head is not for using it with a 4G63 motor. The benefit comes when you put the head on a 4G64 (2.4L) motor. The advantage of this is swapping from a single cam to DOHC. Of course it's not just a simple swap though, I believe you'll need shorter rods and different pistons. I'm not too sure but I don't think it's a direct fit to the 4G64. Anyway, the ending result will be a 2.4L block with a 2.0L head.


I planned on doing the swap a while back, but never sourced all the parts.

 

There are quite a few DSMs well over 800hp

This is kind of debated, volume vs velocity
