I'm just kinda wanting to do a once over small rebuild with my DOHC 4g93E head before I put it on my built block and was curious if anyone happened to know about what is locally available stateside regarding these heads? I'm mostly curious to know about the valves and valve seals. Anyone have any input? Luie is not an easy guy for me to get hold of for some unknown reason so I'm kinda lost without any support. I thought he might have said a while back that 4g63 valves work, but I'm not sure on that. Couldn't come up with much regarding search. Thanks guys.

 

Guess nobody knows? Guess Ill have to experiment some.

 

Where did you get the head? I'm looking for one myself... I have many years of mitsu experience, including many different motors. I may be able to unlock some of the cross over parts once I get my hands on a head and tear it down.

 

I got my head from another member that had originally bought it from llt-racing. I figured by now there were several people that had gotten the head and might know a little bit about the cross compatibility. And llt doesn't seem to be very interested in assisting my venture which im assuming is because I didn't buy the head directly from him. Who knows? I have 3 full 4g94's hanging around my place so it won't be too hard to figure out the cross compatibility for that when I get around to it. Waiting for the weather to warm up a bit.

 

I will keep watching, I am interested especially in finding over sized valves. I'm sure the stem size is common with something else (hopefully 4G63), the question is mainly in length, and width. Hopefully a 1mm ish oversized valve set can be produced...

imalancerman did you find anything i been looking online for the valve seals but I haven't find anything?

 

Haha, its funny. I was just googling info on the valve seals and saw someone had replied to my old post. Bolock13, I don't know yet. I will be taking one of my sohc g94 heads into my machinist when we go over the 4g93E head and will be looking at the compatibilities. Our guess is that it is either compatible with the g94 seals and valve or at the worst (or best) the g63 valves. I still have yet to find anybody that has posted the info I need so I suppose I may come back to the site and keep you guys updated. My block is almost complete so I will be building soon.

Haven't driven the thing for two years now cause there is a knock that I can't figure out in the motor thats in it. Just got through tearing out the dash because mice had gotten into my blower and heater core and made a LOT of nesting. Probably the most disgusting thing I've ever dealt with. Luckily, aside from a little mold on the rear seat and an issue with the blower motor resistor, its really in surprisingly great shape. Just waiting on the machinist.
