Kid_20, I'm a Gold Coast local as well. Although he tends to specialize in Evos primarily, Rod down at Step Up Automotive in Southport has done a fair bit of work to my turbo SW20 and I've had nothing but pleasant experiences. He's a motoring enthusiast himself so it's awesome to have a mechanic that you run into at car meets/track days. 100% recommend his services - I've never had an issue and he's always looked after me when it comes to pricing
 
I've heard pretty good things about Scope (user on these forums) as well but I haven't given him a shot yet as my car is currently a daily & the distance is too far

Scope (Craig) is great.
 
I needed gearbox swap & my mechanic here in Newy wasn't keen, so I decided a holiday in QLD was a nice idea & got Craig to do it for me.  He also gave the car a thorough check for me & fixed a few other things.

Thanks for everyone's help.
I think I'm look at going with Dennis from LouDen Motorsport or Craig from Scope for the rebuild because of your recommendations and previous posts from the past. I really appreciate the other suggestions as well as I now I have options for local mechanics when something breaks in the future or I need a service.
I'll let you know the outcome and what work I get done. I'm still interested if anyone has any recommendations on any upgrades while the motor is out.

The distinct benefit of using Craig (Scope) is that he is an MR2 SW owner & a regular attendee at club runs etc. You won't get better back-up than that.
