So I got this car in 2004, cost me $700, had no WOF, reg, wheels or battery and it was generally a mess. Had been stolen and recovered (twice).
The car is a 1989 S/C manual hardtop.
The day I picked the car up:
In early 2005 I decided it was time to do something I'd wanted to since I got my first AW11 a few years earlier - a 3SGTE engine swap, so I bought this:
Deregistered 1989 SW20 turbo, interestingly it rolled out of the factory 2 months after my AW11
This is how things looked in 2005
To keep this brief I wont go through too many of the details of the swap, I finished it mid-2005, drove the car around for a while before realising the headgasket was blown (I suspect it was blown before I even pulled it out of the SW20), at which point I replaced the headgasket with a Gen 3 metal gasket and installed some ARP head studs. Somewhere along the way I also replaced the CT26 with a CT20B. Other than that the engine has a GT-Four RC water to air intercooler setup, gutted TVIS, a 3" downpipe, 2.5" exhaust, and I usually run around 13psi on it.
This is one of the more recent pics I have of the motor, and it's more than 4 years old
Apparently I don't take many pics of it these days. Things are all pretty similar still, except it's showing the signs of aging a bit
So as well as the engine swap, the other big thing I've done to this car is a vented bonnet and radiator relocation. Did this summer of '05-06. A few quick pics of it:
Hole in the front bulkhead plus reinforcing frame
Radiator for the w/a intercooler

And how it looks all installed
Suspension wise, I installed a complete set of urethane bushes in it shortly after I got the car, currently sitting on Jamex springs and I have some KYB adjustable dampers to try in it later. As well as that I've replaced virtually every moving component within the suspension, ball joints, wheel bearings, tie rods etc. Made my own rear tie rods for it earlier this year:
I've also upgraded the brakes, ST185 twin pots in the front and gen 3 SW20 calipers in the rear with Renault Clio disks
The stereo consists of a 4x80WRMS amp running some Infinity Kappa 6.5" components, a Jaycar Response 4x50WRMs amp running a DVC Audiobahn 8" sub and an old Alpine CD head unit. Here's a reasonably recent picture of the amps and crossovers:
And some old pics of the components and sub (the amp doesn't live there anymore)
Other feature worth mentioning on the interior is the Jamex Daytona seats, relatively light and a really easy install into an AW11
So other than all that, there's a bunch of little things I've done, plus I have a bunch of half-finished projects like a replacement fibreglass bonnet (I made a mould about 18 months ago but still haven't finished it), some other composite pieces for the interior (and exterior actually), and I have a huge list of stuff I'd love to do if only I had the time! I'm currently gathering parts for some engine work in the next few months.
I thought these were recent pics, but it still has my old exhaust on it, so must be a couple of years old.
So there's my car
I've done about 45,000km on it since the swap, including a few extended periods where it was my daily driver. It's never missed a beat, been incredibly reliable, and has been excellent fun the entire time! These days it's kinda my shopping trolley because my daily transport is also my fun vehicle but is less practical than the mr2... 
(every time I think about doing this, I've just spent a few hundred dollars on wheels, tyres, brake disks or something, but I swear I'll do it one day!)
