Not a Beretta, but it is a Z-24 with Beretta siblings...

I paid $120 for this car with a grenaded engine -several holes punched through the block, two rods thrown, one piston completely disintegrated, and the oil-pan perforated like a cheese-grater. The front-end had been used to mow-down the previous owner's mother's mail-box and later her garage door before he exploded the engine 'missing a gear on an off-ramp'


I used the 2.3 SOHC Quad engine from my '92 Grand Am, at this point owned by a friend who wanted to upgrade the 180k+ mile engine with a 3800 after the Quad blew its' head-gasket (again). After replacing two bent valves from the Cavvy's original 2.4 Twin Cam cylinder head, it was fine (despite the ridiculous amount of damage to the rest of the engine), and I was able to adapt it to the 2.3 Quad block. This gave me 4 valves per cylinder, Dual cams, and best of all the upgraded direct-drive power-steering pump (the after-thought PS pump on the older Quads is a bad joke by GM, IMO

About a year later, the oil-pump seized on the 2.3 DOHC hybrid, causing one of the already tired rod bearings to go out for lunch, despite catching the no-oil-pressure almost instantly. The engine now needed a new crank to be up to snuff, so I started looking around. I ended up getting a good deal on a newer, low-mileage LD9 Twin Cam from an '01 GA before I ever found a good crank for the 2.3, and so I dropped that in instead. The newer LD9 has a little higher compression ratio, and ditches the EGR that I love to hate. While it was going in, I decided to add a little IHI turbocharger and intercooler, both sourced from a Ford 2.3 Thunder Coupe T-Bird with low miles. I added an e-bay special Blow Off Valve and a boost-controller, and built a 2.5" full mandrel-bent short-run side-outlet exhaust for the car. Now I had one ripping little Z -this car kept up with my 3800SC GTU, at least up to ~75-80 MPH- for a total investment of around $750, including both engines and the turbo work. A couple of years ago, I was given a pair of steel Z-3 style vent-fenders for the car, so I prepped them and painted them myself with a decent automotive-grade color-match PPG paint and clear-coat -they turned out alright, considering that I had to build my own hot-box spray booth and am NOT a professional painter. I also bolted on a Fiero GT wing spoiler -any bigger and the car would look silly to me. I already had red metallic fader window-tint on the car (it needs to be redone now, most of the red has 'faded' to silver

Recently, I have given the car Enkei 16" rims from a Subaru (the inside hub-hole needed to be enlarged a little on the wheels to fit the hubs on the car), re-cleaned the interior (it sat all last winter, even though this is the best snow-car I've ever had), and just finished replacing the exhaust-tips that were lost in a really bad snowy season two years ago. The new ones are okay, but not as nice as the ones I originally made for the car.

Some other mods include Grand Prix GT hood-vents, and a functional off-set hood-scoop (to feed the intercooler). On the inside, the car has a triple-gauge cluster pod in the middle of the dash with boost, oil pressure, and fuel/air ratio gauges, a newer Cavalier dome-light with twin map-lights built-in, red glow-pedals, red shift-boot, red "Engine Start" button, Pioneer stereo, 12-disk Pioneer Premier CD changer, and Pioneer Amp. Mechanically, it also has an older-style external-slave transmission, LUK clutch, IDI coil mod to use conventional GM coils and plug-wires, and a fuel-pressure test-port on the fuel line.
The car is running a little rough lately, and griping about higher boost-levels (above ~5 psi). I may just have a bad tank of gas in it, but I am tentatively planning a wild ECU replacement with much larger injectors and an adjustable ignition timing system, but I'm not certain I like the unit I am looking at for this, especially since it would be relying on a more finicky MAF system for fuel metering... I'll see how the little car runs from now until then. In all likelihood, the mods wouldn't be permanent anyway... I'm pretty sure he also needs a new TPS, and the IAC may need cleaning -that may be all I need to do here.

Here are some pics, some old, some new.
