April 2016 COTM **Winner**


Congratulations, quadgoat! Your '92 Firebird is TGO's April 2016 Car of the Month. Starting with a base model 'Bird, visual upgrades from 3rd and 4th Gen Trans Ams, as well as the aftermarket give this car a great look, finding balance between bold and sleek. It also has the performance to back up it's fast looks, making her a bona fide giant killer. This base model 'Bird is a perfect example of what is possible with the Third Gen platform.
Great car!








I transplanted the Stealth Rammed 350 I built from the '84 into the '92 along with the T-56 topped with a Hurst Billet Plus shifter, 3.27 geared 9 bolt Posi (with new cones and springs) with PBR disc brakes, and Commander 950 engine management system.

I had never been a huge fan of the '91-'92 Firebird "banshee" nose and ground effects, but I decided to stick with them, although I added a RAI style hood, 4th gen replica spoiler, and '85-'90 Trans Am front fenders with "air extractors" behind the front wheels.

All the bodywork and paint was done by me with a LOT of help from a very good friend of mine and my wife (then girlfriend!). We took one whole week, tore the car apart, blocked it out, painted it, re-assembled, and did the first stage of wetsanding/buffing...

I got a C5 ZO6 front brake kit from Ed Miller using the C6 Z51 13.5" cross drilled brake rotors. I then wrapped the brakes in 18" ROH RT wheels and fresh rubber.

I also swapped the 4th Gen Trans Am seats and center console into this car that I had in the wrecked '84...

The car also has Spohn adjustable tubular rear control arms with poly bushings, a TDS Wonderbar, and UMI subframe connectors welded in.

I was able to participate in the Hot Rod Power Tour in 2008 and the car completed the entire Long Haul from Maine to Arkansas and back with only one issue - a shredded serpentine belt.

The car went under the knife in late 2012 and got a bit of a power update. I guess it'd been together too long and/or it was too reliable, so I decided to add a custom single turbo setup using a Turbonetics TC78 turbo, and retaining A/C and all other "creature comforts". After I built the turbo setup on the 350 I upgraded to a Walbro 400 LPH fuel pump (I got the e85 compatible version, which they tell me is actually closer to a 430 LPH output) and installed a RaceTronix HotWire fuel pump wiring kit...

In 2013 I popped a head gasket on the 350. After trying to get head studs to seal up in the stock block for quite a while I gave up and decided it was time to build a new engine using a Dart SHP block to elminate my head stud sealing issues!

The new engine displaces 412 cubic inches and houses a Sonny Bryant 3.8" stroke billet crankshaft, Carrillo 6" H-Beam connecting rods, and Wiseco forged pistons. It got a custom ground cam from Bullet Racing Cams and is topped off with AFR 220 heads...

I also upgraded to a McLeod StreetTwin twin disc clutch good for approximately 1200 HP along with a scattershield, just in case anything bad happens at the track LOL!

The new engine was treated to a new Holley HP EFI engine management system which has made tuning and drivability even better than with the old setup.

Now I've run into the (not unexpected) fact that the turbocharger I have now is the limiting factor to how much horsepower I will be able to make. The engine should be good for anything I ever want to throw at it, and I'll just have to find a way to shoehorn a turbo with a bigger exhaust side into the space I have!!

Here's a video of the new setup on the rollers. It put down 495 RWHP and 698 RWTQ (peak torque hit at 3500 RPM!). Please excuse the excessive tire smoke from my rolling burnout on the dyno LOL! The tiny exhaust side on the current turbo really choked the engine out, but it makes for quite a fun ride on the street with almost instant torque anywhere in the normal driving range!

Next up is re-constructing the turbo setup to fit a larger turbocharger (probably will require an aftermarket front accessory drive system) and getting a 9" rear end under the back of the car so I can really use all this power!!

Congrats on the win here.
They were all nice but yours was my pick and glad you got it.
Something about the hood and spoiler and color just works for me.

Re: April 2016 COTM **Winner**

Thanks again everyone! She can be a handful when you open the taps and put 700 ft lbs of torque to work at 3500 rpm hahaha!

(Always love watching this one, spins the tires pretty hard on the rollers when boost hits lol!)

How do I get a nice glamour shot on the main page of the site now, like all the other COTM winners? Lol!!
