Funny thing about that Black Piazza, Dave
my wife and i bought it from the original owners in Gawler in 1997. It had 43,000km on the clock with a letter of identification from Delaer as to its provinance. was owned by a middle aged couple who drove it to shops and church. they had to upgrade to a commodore sedan to allow easier access into the back seat for their 75 year old mother.
we only did about 35,000 in it in 5 years or so and sold it onto a family friend. it stripped the timimg belt while my wife was driving into a service station one day and it would not start. got it towed home and very very fortunate to not have any valves and pistons come together.
replaced the belt and water pump and away she went.
we were also the ones to put the AA plates on it as well. a real pity someone pulled the original engine. most likely a gemini head wanting bolt in performance.
good to see it back on the road

Hi! I'm Eli, that's my black Piazza! Great to hear from a previous owner
and to have its story. Definitely saved that away for future nostalgia. That's crazy about the timing belt! I'll tell you my part of the tale:
I saw this thing for sale on Gemisa.net as a complete car a few years ago, for around $3500-$4000. At that stage, I couldn't afford it, so I had to let it go. It was being sold by Chris (G200-Gem), and was bought by Stoy, a guy who lives in the northern suburbs and has a nice Gemini wagon. He drove it home, it spun a rod bearing on the way, and he pulled the engine out to put in a Gemini (bingo). He then put the car back up for sale minus engine, for around $750. It was looking like it was going to be parted out and crushed - being that there isn't much market for a whole Piazza shell, or many people game or stupid enough to try and re-assemble one that they didn't personally dismantle. I'm a big Isuzu fanboy, and I just couldn't stand to see it die.
So, I bought it. Probably one of my crazier decisions, and if I'd known what I was in for I probably would have just saved up and bought a running one. It took two years of hard work, bleeding forearms, swearing fits and empty bank accounts to get the damn thing running, but somehow, I did. This process also included a road trip to Melbourne to pick up a 4ZC1-T in parts (from "Shorty" on OzGem), which itself resulted in a dead Gemini on the way back, and later, a trip to Balranald to pick up a whole spare parts Piazza (from Eyecon) for reference, and those odds and ends I couldn't find. Incidentally, rather than taking a step sideways on the "Save The Piazzas" front, I've replaced everything mechanical/essential that I removed from the spare parts Piazza, and have taken a deposit on it as a whole car, from someone who wants to fix that one up! The cycle of life...
Anyway, here's the gist of what I've done to the old girl:
- 4ZC1-T sourced from Melbourne, full rebuild, new rings, rod/main/thrust bearings, timing belt and tensioner, oil pump, graphite head gasket
- Custom JE forged pistons, 8:1 Compression Ratio for higher boost (later)
- ARP head studs
- Bored 20thou, block/head cleaned, crank machined, head reconditioned, machine work done by Krieg Engines, assembly by yours truly
- Shimmed LSD, sadly this accomplished precisely nothing, and it still open wheels everywhere
(not giving up on this just yet)
- Sourced, cleaned up and fitted the somewhat rare factory front lip
- Original Isuzu grille badge, circa Piazza, and "ISUZU" rear garnish sent over from NZ
- Dished velvet "drift" steering wheel, couldn't stand the "Holden" item and this feels a lot nicer, without looking too gaudy
- Koni Red front shocks - will be ordering rears pending springs - max'd standard adjustment for negative camber (estimate -1deg)
- Narva arctic white headlight globes - bluer than I wanted, and not really that much better... I'm considering a white HID kit for more light and a factory(ish) look
- Rust repairs on the rear hatch including window out, weld, bog and paint, as well as treating, bogging and painting rust on the driver's door, doing some welding on the left C pillar inside (ugh, don't get me started) and getting the bonnet resprayed
- A bit of housekeeping (welded up a battery bracket as it didn't have one, replaced the relay for the headlight covers)
Plans from here:
- Lowered springs - ideally I want about 10mm vertical guard gap, I don't like tucking, but it looks like an offroad vehicle!
- Koni rear shocks to match the front
- Establish a functional LSD
- Piggyback fit a Megasquirt fuel+spark ECU unobtrusively, with minimal/no modification of factory loom
- Mild cam to improve response
- Fit my T2 manifold with my GT2860RS "Disco Potato", and my Merc 380cc hosetail type injectors (have the parts, need the time), using fairly factory piping runs and preferably black piping, so the engine bay still looks vaguely original
- Possibly fit the factory rear spoiler
- Fit splits inside standard front speaker cavities, and fit 6x9"s in boxes in the boot area (ie, no interior modification)
Basically, I want around 200rwkw with decent response and decent handling, but retain an overall tasteful package that resembles its original orientation and only includes reversible mods.
Doubt anyone read all that, but yeah. That's my Pizza-bus! Also, I call it the Tardis
Eli
