Hey guys, i just got a interesting trade opportunity to trade my 1983 Thunderbird Heritage with 80K for a minty 1984 Turbo Coupe. Both are white cars, both in about the same excellent shape and we are both willing to straight out trade.
The TC is White with the charcoal 2 tone lower treatment and a grey cloth interior in amazing shape. Its an Auto TC which for 84 has to be a very rare option, and is the perfect unicorn car that i am attracted to. This would be my first TC and first 2.3 Turbo. What should my concerns be for this engine and turbo and what other trouble spots do i need to look for?
Thanks

Those Turbo Coupes did like to auto the automatic transmissions. I don't know about back in 84.
Personally, unless it was an upgraded motor, it'd pass. It's easy to drop in a 5.0ho into a naturally born 5.0l car if you want more power. I don't think I would do the trade.
On a side note, how do you like your 9-7X?
Speed on these cars was never my overriding concern or criteria. I am into preserving our 4 eyed cars especially well preserved survivors as both of these cars are. So the power differential for a 5.0 stock motor from 83 vs a TC 2.3 is probably about the same in terms of performance with the 2.3 a little easier to squeeze some power out of i have been reading. I welcome more discussion about it.....
As for the 97X aero, it is my favorite non-Ford car i have ever driven. Fast, fast and did i say fast? LOL Its a very spacious, well equipped and thoughtfully designed truck, the 4.2 is powered ok, the 5.3 is lively, and the 6.0 which i have is an amazing motor. Its the LS2 vette engine.
If the T/C is in sound shape body wise and the engine shows no obvious signs of issues (knocking, smoking etc.) I'd go for it. The early T/C's are getting rare and the 2.3 is a stout little motor, it can easily make more power with some simple modifications if you choose to go that route and there is a lot of on line support for them. The only drawback is the auto tranny, they are the weak link if making more power.
Personally I would keep the 5.0 car if you're not planning on modifying the car. It's going to be less maintenance intensive in the long run. Plus 2.3 turbo cars are not much fun with the auto trans. They have worse driveability with the auto trans than the 5.0 in your current car does. If it was a stick it would be a different story.
I dunno, assuming the '83 is EEC-III, think I'd dump it... It's either that or one day convert it to the EEC-IV electronics...
Bingo..... that was my thinking as well. For me, fog lights, tach and floor shift = 200% perceived HP increase anyway.... lol
I've owned cougar-versions of both cars. It's about a tie to me. I like the XR-7/TC interior better. I Like the "lighter" feeling of the 2.3 when driving. But I like the instant torque of the 5.0. As far as reliability, they are also about the same.
The 2.3t auto gets a bad rap, but my current 85 XR-7 is an auto (and I owned an 84 turbo auto) and they are plenty of fun. I think in a race, my stock 83 5.0 would have lost to my stock 85 auto/turbo. But my 83 was the king of pulling trailers, lol.
So basically its just a matter of preference at this point. I think im ready for something new and different in Thunderbird/Cougar land.
1983 Turbo Coupes have EEC-IV IIRC.
Go for it... The '84 is first year for TC automatic and I doubt really rare(were std in XR7), maybe a quarter to third of total... The early TC used the C3 automatic, not super strong but far better than the A4LD used in '87 & '88... Biggest downside is with 3.45 rear & no O/D you'll be looking at shifter trying to find another gear...
I liked the auto in my white TC, with boost cranked up it was fun... I wasn't worried about the A4LD as car was slated from day one to become a 5.0/AOD swap victim...
The 84-86 XR-7 Turbo cars were Auto Trans standard? 5 speed was the upgrade?
Yup, that's my understanding...
I dunno if it was a no cost option or possibly issued some credit if 5-speed was ordered...
I wouldn't trade a od trans car for a non of car if I ever intended to drove it any sort of distance. The od gear would probably make freeway the same or worse then the v-8 in all conditions above 35mph.
For the XR-7, it varied depending on the model year.
In 1984, the automatic was standard and the 5-speed was optional.
For 1985 & 86, the 5-speed was standard and the automatic became the option. In 1986 the Automatic on the XR-7 was priced at $315.00.
Trade it. :)
My old 83 5.0 w/OD got about 22mpg on the highway. My turbo C3 gets about 18-19. Not a huge spread. Now, my old 87 XR-7 with OD got much better mileage. Its been 20 years since I owned it, but if I recall correctly, that thing was near 30mpg on the highway if you keep your foot out of it. I think it had a higher rear-end gear though, and obviously the more modern SEFI.
If you really wanna see the non of difference in fuel economy, drive around in d instead of od for a tank of gas. It will surprise you. In my old 87 bird driving very carefully with a 50 mile mix of 55-75mph I could average 28mpg highway consistently. Being really gentle I nudged it above 30 a few times and once got 675 miles to a tank of gas over a weeks driving. I ran out a mile from the gas station though. Driving around in drive (non od) I got 22 mpg. It was a huge difference.
Buy the TC and keep them both! :)
Can't do both right now, i think im ready for something different anyway.
I still say keep the 83. That's just me though. I tend to keep cars I like for awhile though (I've had my Thunderbird since 2002).
I wish i could do a few cars, but i don't have the cash, or storage to do so. Honestly, the new 83 i traded for the Cougar is a fun and cool car, but it is not my original car, and i don't have any emotion about it one way or another.
I tend to keep cars awhile too. Let's see, I've had my '83 since, mmmmmmm yea 1883. ;)
From a investment stand point, the Turbo should be a little more valuable... But the buyers will be a smaller group...
All great points to consider..... i think i am just ready for a change until a look a like for my lost 83 Heritage presents itself.

For Thunderbird TC in 84 per all the dealer literature, its the opposite case....
That's true.
Two complete guesses on my part:
Guess #1. Either marketing figured that the typical Mercury buyer would prefer an automatic over a manual.
Guess #2. This was changed for the following year when they woke up and realized that they could charge extra for the automatic. :evilgrin:
So are you trading?
Yes, i think so.... i am working out details with the other party still.
