Turbo Build

[DomMINIque]

So I'm posting this so that the experts can tear it to shreds.. 

This is so that the expensive mistakes can try and be avoiding as much as possible.

So I'm planning a turbo build.

So far I've got the following parts:

Evo Water Pump
Metro Turbo Oil Pump
Unleaded valve seats
3.1 diff 

Parts still to come:

HT EVO Cam

Then this is where I need some direction. 

My plan is as follows:
1275 +20thou pistons (Hypatec)
1100 Crank
1100 rods
Std bottom end
3.1 diff. 

Based on the above I know about 5mm is supposed to come off the block.
However I want to see if I take a little less off and can then avoid the use of multiple head gaskets. 

Cylinder head:
Unleaded valve seats. 
Currently already has gts size valves in. 
Port/polish and flow. 

Minispares intake manifold
Hif turbo carb (not sure on needle either - from some of my turbominis research it seems most use the BDD needle.)
Garrett T2 - mounted over the clutch/bell housing. 
Locally made plenum (if I can figure out what some of the terminology means of the turbo mini forum)

My issue lies with dizzy. 
Is it possible to use a normal dizzy (converted to electronic) to run the turbo motor?

AFR gauge will also be a definite.

The plan is to run up to 1 bar max boost. 
I want something that pulls like a bit of a train but is reliable doesn't sit parked for months on end because everytime it does run it breaks.

I've roughly worked out compression on the motor as follows:

The main thing bring the compression down is the mm below deck height. 
If I increase the mm below deck height to 3mm then the comp ratio drops to 7.8 which I may think might be a better option. 

A picture of the head to be used for reference, will be redone for obvious reasons.

Let me know what you guys think and what I've left out.
