yea i got quoted for a low km swapover motor from $800>1500 (ae82 4AGE), which is kinda cheap cos it includes all labour and warrenty etc..
+ hard to get in good nic these days....
so in ended up buying a low kms 2nd long motor for $200 and did it my self.
i also picked up another long motor for $550 with 3 months warrenty and did the DIY swap over also.
