TTA #1078 Restored w/Mods, Owner Jan Larsson, What a Beauty...
Let's see some more TTA builds, any TTA owners lurking??? Post them up... 

Re: TTA #1078 Restored w/Mods, Owner Jan Larsson, What a Beauty...
Don't have one, but definitely one of my fav third gens by a good margin. Probably one of the last great BOP engined RWD cars before everything went 100% corporate.

It is awesome that you guys are keeping them in such great condition, what are you mods to your TTA? Have you taken it to the track for any numbers...?
Re: TTA #1078 Restored w/Mods, Owner Jan Larsson, What a Beauty...
TA49 turbo with adj. wastegate with about 20lbs of boost, 60lb motron injectors that are match flowed with a Turbotweak Alky chip. Adj fuel pressure regulator along with a intank Walbro 340 fuel pump that is hot wired, plus Alky Injecton from Alkycontrol.com from Razor.
Here is a video of TTA984 that autotrader classics did at the spring turkey run in Daytona in 2012:

That is just awesome, those GTA rims are polished so nicely! Kicking myself that I sold my GTA rims to a Grand National buff in favor for my TT2's. Most members here don't realize just how fast these TTA's will run with that TA49 turbo, at 20-psi your probably running 11's without even breaking a sweat. That is one nice TTA! Do you have any information about the prototypes? Are they still around, or is someone harboring them in a garage somewhere...?

A man named Rich in Atlanta, Georgia area has the black emissions car and the flame red car as well as one of the convertibles. I have not seen them but a friend of mine saw them and said they were awesome.
By the way, my TTA was sold new in Trenton NJ and spend most of its life in Tennessee before I brought it to Florida.
The TTAs are a blast to drive, so much fun spooling the turbo up.

Re: TTA #1078 Restored w/Mods, Owner Jan Larsson, What a Beauty...
I only have two pictures of the red one. Someone had mentioned they seen both cars over in Englishtown Raceway Park a very long time ago when GM brought them down to see how they would do, and the way he told his story was just awesome. He had no idea what he was looking at initially, he brought down his '79 Trans Am and seen the Black one which was an '88 GTA with 305-TPI that GM converted to that prototype, and he said that the car was before him at the staging lanes. He said he remembered watching that thing go down the track from behind, and all he seen was the heatwaves from the track being pushed aside as it ran mid elevens, which apparently was extremely fast back then. He had me laughing, but it was an awesome story though. Here are the pics that I have of Flame...

I didnt know there were prototypes of the TTA's that weren't white. Are those legit photos? If so I have learned something new today, ha

Saw this beauty at the Pontiac Nationals at Summit Motorsports Park in Norwalk, OH August 3-5. Enjoy! Any idea how to find out which number this one is?

One of the guys I race with, actually lives right around the corner from me. I believe it runs high 10s in Mod Stock/Pro.
