I have a 95 galant that i just picked up for next to nothing. it currently has the stock 4cyl. i have been told to do the dohc evo engines but i was leaning more towards the v6. which is better?

Also i am having trouble finding parts for this car. i believe the body style range was 94-98???? but i need a new dash for it. if anyone can help that would be awesome thanks.
