I was thinking of boring the block out on mine to a 5L then sleeving it.

Comparable to stock until you build boost, sooooooo it sucks lol. You could increase displacement but the stock turbo's don't move enough air to properly support that. With more turbo there is no need to bore.

I have signed up to this site after discovering this thread! This level of customisation is insane and I love it! I am trying to upgrade my techart 2003 ctt so I'm following closely 
i need to get some extra power to keep up with the super cars when I'm on track days (my pig is a safety car 🤣 you can see photos of this on insta @955safety)
One question i do have is was the antilag a ecu code or physical device?

ECU coding. We found that with the automatic, a tq converter, and load, that the ignition retard portion of the AL / LC caused the engine to bog down severely and there was some undesireable consequences. Playing around with it we took out all the Retard and only left the ignition cut which allows the RPM's to reach the setpoint quickly and the engine still builds boost because of the load. Makes for a nice launch control and AL is very hard on the engine anyway. A two step box could probably be integrated without ecu coding to get the same effect.
I do have one other thing to ask, did you ever find a way to override the 4k rev limit in neutral / Park? I seen the video of you popping some flames and love it, but I'm just happy if it pops 🤣

Just keep in mind that all those crackles and pops are very very hard for stock cat converters. If You want flames, the original cats and mufflers also need to be swapped. The originals do exactly what it says on the tin. They muffle sound (and flames).

This. Those crackles and pops are unburned fuel exploding in the exhaust. Not sure how or why this became a thing - it's the sound of an improperly tuned engine and that extra unburned fuel that passed through the combustion chamber contributes to oil viscosity reduction from fuel contamination and bore scoring.
