Spoke to Dominello's about rebuilding my 4 speed and told him I should make around 400rwkw with my new engine.He said should be no problems and he offers a warranty on his box for 12 months. He quoted me $4500 with a new 3000 rpm converter, he done my mates box and it has been going for about 8 months now, and driven like a wrx stolen by some 16 year olds and still no problems. People say $4500 is dear but not if it is only done once.
