So, I'm going forward with the plan to swap the SOHC head for a DOHC head. I picked up a head from a buddy of mine. I was aware that the engine jumped time, so a rebuild was planned for. I finally got around to fiddling with the head.

I pulled the cams, rockers and lifters. I am currently leak testing the head. Check this shit out.

Its always interesting seeing more ppl doing this swap
Honestly, I can't wait to start tearing into it. The main reason I've decided to go with the 4g63 swap is because I just so happen to have a 4g63 and a transmission laying around. And the biggest push has been the fact that I just so happened to destroy my current transmission (most likely input shaft), so I figured it's now or never.

The transition going out on my is how I ended up doing the swap too. Just a suggestion before buying any go fast parts just make sure the swap is completely done and running right with all maintenance done. Also don't cut corners like I did because you'll pay for it in the long run. Well good luck and god speed.

Looking to do this to my 98 Spyder automatic. Is the list pretty much the same? What things would vary from the manual? Fairly new to all this so any help would be greatly appreciated.

I'm not 100% sure but it should be AFAIK. You could always manual swap your car too, if you're into that.

You might be able to get parts for those from Ricky (@dacowgod) at rixracing or Stevie Miller at Miller import Parts.
Thanks man! I've been researching everything I can but all the posts I was looking at were super old until I actually joined. Nice to have some info that isn't 10 years old. I'll look into those.
