I haven't tweaked my wife's 740 NA (she loves it stock), but have modded my 244 Turbo.

Things I've done that I'd suggest:

Front and rear IPD swaybars.

Lower with IPD springs.

Shock / strut upgrade.

Support / stiffening rods, as available.

Turbo upgrade: I got one from an aftermarket company in Colorado, it is bigger and pushes a lot of air; there is greater low-end power and more turbo lag, but my god it is great when spooled up: effortless.

I put on the most aggressive rubber the wheels would take.

Had the head tweaked and enhanced for better breathing and near-indestructibility.

Replaced the engine compartment wiring.

I still plan to change out my exhaust (goodbye, cat!) to a wider pipe: that will make a definite difference.

Turbo upgrade: I got one from an aftermarket company in Colorado, it is bigger and pushes a lot of air; there is less low-end power and more turbo lag now because the vanes are bigger and heavier and take longer to spool up, but my god it is great when spooled up: effortless power at speed with seemingly endless reserves.

I have Megasquirt&Spark Extra in mine. Around 275hp with M5 mustang transmission.

Wow, that is one super rusty engine block, the manifold sure looks nice though.

What's the purpose of cutting out the drain bung in the block? I didn't look at every pic yet.

That dead engine block served its purpose as a jig. The drain cut was to help me accurately bend the drain pipe. While I was bending it the pipe had to be longer than necessary in order to get a good grip on it. The only way to test fit it was to swing it in position.
