Speaking of little upgrades, my 3sgte stroker (5sfe crank & stroker CP pistons) build I used a shimmed 1998+ 5sfe oil pump which has greater flow than a standard 3sgte item. Might be something you could look at Rob? Fits both 3s and 5s blocks.
 
I bought it from MCS motorsports in the US which I think no longer exist.

That cast impellor seems to be in the Aisin gen 3 pumps and is the ducks nuts.
GMB pumps on the other hand all appear to have the pressed metal impellor.

Epic build Rob. I like how it's such a high HP build but still looks extremely tidy and not OTT.

Sorry to hear about your main caps cracking.  Were you logging your engine data at Wakefield on the day you think the damage occurred?  What type of knock control does your Adaptronic ECU use?

The only reason why the cost is more of a factor than it has been in the past, is because I bought an apartment this year and renovated it.




 
Look out mate, next things after that are wife and children...

I thought of another significant factor.
As I mentioned already, if I use a 5S crank and keep my 3S rods, then the crank will have to be machined to suit the smaller big end of the 3S rods compared to 5S rods (I've read that it's a 4mm difference). This means that it may be possible to get an offset-grind on the crank to get even more of an increase in stroke, up to a maximum 95mm stroke. If I used a 5S block, 87.5mm pistons and an offset-ground 5S crank with 95mm stroke, then I would have 2285cc displacement!
However, the pistons would have to be very much a custom item, as there probably aren't any off-the-shelf pistons to suit this setup. The wrist pin would need to be 2mm higher compared to a 5S piston, and 4.5mm higher compared to a 3S piston.

That's a 2.3L then
Has anyone done this before?

I believe so. I have to do more research.
