So im getting ready to start getting the parts for my dohc swap so i just wanted to make a thread with the list i think i needto make sure i got everything correct. So far i got:
G63t 6 bolt head with intake(modded for rwd), fuel rail, etc
Sensors, ecu, and harnefrom 1g dsm
4G64 dohc cam gears
G63 headgasket
Then the typical water routing stuff with a full 63 swap. Am i missing anything?Attachment 19491

Another member has asked about improving the HP from their 4G64 so I added this link as a starter -

It is laid out in a straight forward manner and gets right down to what you need to know. :)
I can't find anywhere where it says the pistons need to be changed when doing a dohc swap on 7bolt 8 valve 4g64 mighty max engine, but I'm 99% sure the valve relief pattern is for three and not 4 valves per cylinder. Can someone confirm the pistons don't need to be changed in a 1995 mighty max?
I'm thinking you might experience contact. I would just change the Pistons, an out-of-round measurement on the cylinder walls would make me sleep better at night if it was my engine. An out of round might be the tie breaker in either direction.
