An update on today's activities:
I had a day in lieu today so I took the time to do a few car-related things
Firstly I picked up my 3D floor matts from the post office. Great product! They're so cool!
Then took a drive up to the Sunny Coast to speak with Kris at Rising Sun. As I said in my previous post, I have asked him to get me a VF56 and associated hardware. I'm hoping to have this about late April. 
Also spoke with him about a new engine. The engine I have is high km (just shy of 240,000) but appears strong: other than a rough idle (dirty sensor somewhere??) it runs really well and revs smoothly and cleanly (actually revs a little freer than my old SH Foz which had ⅓ the kms, go figure). So he threw a few options at me: V7 STi EJ207 shorty with my EJ20Y heads, ADM EJ257, JDM GR/GVB 207, or a built 2.5L block with my EJ20Y heads...
All are about the same coin and they all have their strengths and weaknesses. 
After having thought most of the arvo and evening, I'm thinking a built 2.5L block with the LGT heads. This has the benefit of more low-down torque than a 2.0L (minimal yes, but still more), and doesn't "need" to be revved as hard as the 2.0L does; a consideration for me given I have an auto. Also has the benefit of, if done right, ending up with a combo capable of close to 300kW but will only be working to make ~225 on the VF56. So it won't be overly stressed. 
I do appreciate any input from others who've had any experience with a similar decision (unfortunately, Mick, the Spec C engine is becoming a bit like unicorn crap apparently...)
Also today (yeah kind of a big one), I picked up some speakers and amps for my car:
- Polk Audio components and coaxes F & R,
- Clarion shallow 10" sub (to go in the same spot the McIn sub goes, the side panel on the boot), and
- a Kicker 4x 80W and Option Audio mono 300W amps run power them. 
Install of the amps cabling (power) started tonight:

I'm going to take it Slowly and get it do e right the first time. I know I could pay someone to do it much faster, but that to me is cheating. 
I'm still undecided on the HU: I'm not sure if I want gps built in or just a great double DIN HU... Agai , any words of wisdom??? 
Thanks for reading
