I think I'd like to aim for similar to start off with, and once I get it running I'll upgrade parts.
I have everything I've listed in the first post except Pistons, Conrods, Bearings, Head Gasket, Turbo manifold, head studs. I'll go out to the shed now and have a play.

Unless the billet crank works out to be sub $1000, I wouldn't go that route given your plans. 5S & 3S cranks have been doing the hard yards for years without dramas.
 
With that GT3076 turbo, you won't need more than 8000rpm, in which case Eagle rods will hold up fine with the added benefit of reduced weight. If you do however, intend to go beyond that turbo & rpm limit, good idea to invest in Pauter/Carillo rods.
 
Another suggestion I'd make is to use a 3S crank for the better rod ratio. You'll still get increased displacement due to the larger 5S bore (along the lines of approx a 2.1L motor). Less hassle with crank gear & flywheel bolts too. I had a 3S block with 5S crank (not so far apart in displacement) & my GT3037 spooled exceptionally well. The better rod ratio should make for even better setup. In conjunction with the lighter Eagle rods, it'd be a nicely setup & priced motor. Btw, I really like my CP pistons 
 
I'd expect such a setup to hit 20+ psi at around 4400rpm. The below is with a restrictive exhaust/cat, but slightly smaller hotside GT3037/76.
 

 
Would leave you with a wide 3600rpm of serious fun to play with.

The off the shelf pistons wouldn't work with the 3s crank would they?
Wouldn't you need taller pistons or longer rods?

if you used std 3s crank then you'd use the std non stroker 3sgte pistons, you'd just need to get them in an 87-87.5mm bore for the 5s block

or you could use the 5sgte pistons and get longer rods made which is sort off what i've done, except i have to get custom pistons anyway due to beams head not suiting gen1-3/4 3sgte pistons

Thanks for everyones advice so far, and sorry I haven't updated this sooner.
A few things have changed in the last few weeks. 
First big change is I now have a W2A intercooler from frozen boost. 
I have decided to split my 5sgte build into 2 parts. the 5S will still get built but for now I have a 3S getting put together. The reason to do this is to use parts that I already have, saving money initially, get my car running again with this 3S an build the 5S once I'm driving again.
Bottom end is getting put together as I write this.
Includes: 3S gen 2 block
Ross forged 1mm over pistons
New Rings
Eagle Rods
ARP Crank Studs
ACL bearings
Gen 3 MLS head gasket
New oil and water pump.
Standard head, Standard cams.
Walbro 255lph pump

Sorry didn't get to finish above post.
I have another set of choices to make. (You're all going to be sick of me soon)
Turbo: I have a Hi-flow ct26 and a Garrett GT3076R with 0.82 A/R T3 exhaust housing. I'm thinking put the Garrett on the standard manifold with an adapter and sell the hi-flow.
I have the set of HKS cam gears I can put on, (is it worth it?)
I have a standard ECU and a SARD ECU and the Haltech E8. I'm thinking the SARD to start for simplicity.
Also have a light flywheel for it.
Do I also put the 720cc injectors and fuel rail on it too? Is the SARD ecu capable of this?
 
Best this is, it's all happening. Just designing brackets for this W2A and remote oil cooler at the moment.

I know this thread is old now though make sure you don't buy Ferrea oversized valves. Go with Supertech instead.
The Ferrea valves are faulty.

Hope you lot don't mind some ignorant questions- hows the block height between the engine? How about the OEM compression height of the pistons? Seeing the 3S rods can be used and assuming the same compression height that would suggest it's 2.5mm taller.
 
Going off what I hear about 3S engines wearing out the sides of pistons it would be a good idea to move the pin higher to help offset the rod to stroke ratio.
 
Too bad a Beams head can't be bolted on to a 5S block due to the lack of VVT oil feed, I have however wondered about the option of put a plug in the head and feeding it externally. This is getting off topic though.
