Tyler's 1996 Base

Tyler Thomas’ 1996 Base 3450 Supercharged

Some words from Tyler about this beast:

Well, let me start by saying that it has been a long journey building this car. I have owned Berettas since 2008; this is my 2nd. My first was also my first car in high school. This car started out as a shell brought to me from some good people out west. They towed it with a van for a long road trip to my house in SW Pennsylvania. They seemed to be as happy to put it into my hands as I was to get it. I knew I wanted this build to be bigger and better than my previous supercharged setup, aka the garbage RSM kit I bought.

I completely re-machined every piece on the supercharger kit over time. I had a good friend of mine rebuild the engine, install forged internals,  a cam, and lastly and most importantly road-tune it. Over the past three years of working on my girl, I finally feel like she is to a reliable point. I can wake up and take her to work, sit in traffic, and beat the hell out of her and not worry about something failing. I also had her on the dyno last fall. I found out after 9 psi my intake air temps went through the roof causing my timing to retard, I ended up making 308whp 368tq. I have since upgraded the water pump for my W2A intercooler system and also gone a stage colder on my plugs. I hope to make it back to the dyno sometime this year and improve those numbers with the newer modifications. I may even possibly go E47 or full E85 to see what type of power I make.

If you have any interest in learning more about my Beretta feel free to message me to talk, there are way to many modifications to list.

Eric's 1991 SS

woody90gtz – Eric Wood’s 1991 “SS”

If you’re reading this you might already know the story behind the “SS.” It’s originally a teal ‘91 GT 3.1v6/5spd car. I bought it as a bare shell in Jan 2009 and turned it into my summer DD – finally driving it that July. My first car in high school was a Quad GTZ that I sold to buy a 3100 Z26 in college. After a lot of work, that car rusted out from under me and donated some parts to this one. I think of it as the “SS” Chevy could have (and should have) built.

It has the factory Z ground effects and a lip on the front and some 17s with sticky rubber. I painted it gray in my dad’s garage with a Summit kit and 2-toned it later on.  Other  than that the exterior is stock. I swapped in a 3400 out of an ‘04 Impala with modified headers and K&N intake. I shaved & engraved the upper intake manifold and deleted & smoothed the EGR. Clutch is a 2+ from Spec and when I rebuilt the trans I converted the open diff to a limited slip with the help of Engineered Performance. It sits on Eibach springs and KYB shocks & struts with a combination of GM and DIY chassis bracing. Brakes are the upgraded 92+ up front and rear disc conversion in back with good pads. It stops AWESOME. Front sway bar is FE7 spec and the rear is a solid Addco. Inside I fabbed mounts to install some leather Cobalt seats, as well as using a leather Z34 steering wheel and Z28 shift knob. I converted all of the interior lighting to red LED ala Pontiac and made a custom gauge and stereo faces on the CNC and printer at work.

The car is a lot of fun, and I beat the snot out of it. I’m guessing it’s about 220hp, but it’s only 2700lbs. My best time at the strip yet is a 14.4@96…but that was with a bad 4th gear that died completely on the next pass. I think with a clean run it has a shot at a 13.9. It’s also good with lateral G-forces on the autocross – big grins. Great road trip car, too. I’ve driven it all over from Boston to Tennessee, and more will come. I don’t plan on this car ever leaving my possession. It will even get a tube chassis RWD pro-touring build once my bank account agrees. haha

Jon's 1996 Base

Jonathan Chmura’s 1996 Z-Clone 3500 4T60E HD

I’m not sure how to describe this car other than its a ever progressing project that has changed direction multiple times in it’s life, but in the end has always acceled in it’s original discipline.  I’ll be blunt, I bought this car after building a hybrid engine for my 95 and then splitting up with an ex GF… I was driving my 95 daily with this engine and saw what it was doing to it in a daily application, and seeing how I was on my own and didn’t have to ask anyone for permission I just bought this car.  Granted it was also brought to my attention probably at the best possible time.  It was purchased from Ansonia CT so somewhat local to me, a base model raspberry V6 auto car with 74k on the clock a cracked radiator and basically no rust problems.  So I get this car to my place and I also have a Z kit acquired to bring it’s appearance up to snuff… I’ve done the base look for so long it was time for me to go Z.  That’s where the basic info stops and the drive line stories begin… There were lots of changes with this car over and over again to tweak it to what it is today, and to be honest the transmission is currently out of it right now being tweaked once again as I’m learning more and more about it.

It seems odd to say  this but this car has really only had two engines… It feels like way more have been through it but it’s mostly just been removal for inspection or tweaks more than actually changing the motor as a whole.  It started with the Hybrid engine that came from my 95, When that was cleaned up for use in this car I also purchased a new very large camshaft for it as well as some much stronger valve springs…. Many of this stuff was not available at the time of building my first engine so I went all out on the cam this time around.  That setup ran till Jan of 2010 when I pulled that engine to go through it and update some stuff.  In between it had been serviced for a bad timing set, and some other various problems.  I can say in its first outing in 2008 the car put down a 13.996@98 in the 1/4mile at Bfest Niagara Falls.  Best time for a 3400/3500 4t60e Beretta.  Only recently have I been able to beat that time and one needs to remember other changes that were done to this car between then and now actually slowed that 13.996 down to a 14.3/14.2.  It wasn’t till Winter of 2014/2015 that I would decide it’s time for a new engine to make this car quicker.

Insert the ambitions to put a 3500 for good in this car and get it back into the 13’s without any nitrous.  Search began for a 3500 engine with the proper forged crankshaft since I knew that should hold up best to what I would be doing.  I found one locally with 45k on it and bought it, at the time I did not believe the crank was the proper one until I had it all apart and proved that to be incorrect.  During that build I found that I would need to replace my camshaft due to some wear as well as that would require new springs and pushrods, so I went all out and had this motor blueprinted by myself and every part of it gone through carefully.  Had the rotating assy balanced, pistons measured and bores sized independently for each one to ensure proper fit and so on… I could go on forever about all the detail work and customization that went into that 3500 but to save on this post you can read it all here… Since the 3500 project start, the car has also be upgraded to a 4t60e-HD transmission and the HD CV joints as well… I did however immediately break an axle shaft on my first visit to the drag strip with that setup.  Everything had been upgraded but the axle shaft itself, and that had been slowly twisting since 2008 and finally decided to let go.  All of those changes update and problems aside, I’m back to ripping into the transmission to learn more about it, how it shifts and why, improve upon that as well as find and identify a problem that resulted in low line pressure and extremely poor shift quality on my last visit to the dragway.  I will leave you with this… A full or maybe full list of whats done to this car.

I’m sure I’m forgetting something but I can only remember so much.
All I care about is, It’s Pink, It’s Loud, It goes fast, It stops quick, and It turns when you tell it to.  This car has been a journey and I’m sure it’s not done yet and will probably never be done.  I hope to continue to expand upon it’s accomplishments and make this one Beretta that can never be forgotten.

Cory's 1992 GT

Cory Cain’s 1992 GT 3.1

Here are some words from Cody about his GT:

At the age of 15, my parents made the deal they would buy me a first car, of their choosing, and if I liked it, I could pay them back for it. We looked around for a car for awhile and eventually, one Saturday morning, I was shocked to see a white 1991 GT sitting in the driveway. Through my high school life, that car was my best friend, and cleaned better than my room. Once out of high school I made the decision to trade her in. This past May, at the age of 30, I started feeling nostalgic, and found this little girl just a state away. A very good memorable road trip(with mom, dad, and a brother), I drove her the 4 hours home. What a blast from the past, and what fun little cars they are. Thank you again for enough votes to get her on a calendar, I’ll never forget it!
