check over on neons.org for that. There are 2 people swapped everything! Down to the cluster, interior, and such! Took them about 6 months start to finish! Good Luck!

Edit: I would go Megasquirt though. Ability to tune everything will net you way more hp than just a ECU/engine swap and save you about 5 months and ungodly headaches!

 

old thread but ok, Go to neons.org and get the maddog Adapter plate for a sohc. it will work but your block i think will only hold 6-8psi..you really run the risk of blowing it up after that.
to be honest, I wouldnt waste my time, you can get totalled srt4s from 2k-6k and do the swap and get other parts as well.
