Remember this was the late eighties, early nineties... The car would have had gas Guzzler tax on it.

Mazda was nearly killed in the mid 70's when the rotary motor was considered as gas guzzler, and corporate philosophy said no Mazda product sold in the USA would ever be labeled a gas guzzler again.

If you look at the top of this section, you will see a sticky thread marked Standard features and options. It contains all the US models and what they came with based on year.

They ran into issues with cooling (the stock FC rad was too small for hot weather testing in AZ) and the gas consumption was horrible (around 11-12 MPG I was told).

Car and Driver, caught wind of it and printed this in mid 88


If you read the fine print, you'll notice how it says they will be powered by a 3 rotor.

the project engineer for the GTUs (his first full project for Mazda- and a major player on the RX-8) was embarrassed to be associated with the GTUs when Corporate decided to emasculate the GTUs with removing the motor of choice, and putting in the band aid of the 4.3 rear end instead.


.

if they replaced the 20B with a 4.3 rear end, why not replace it with the turbo engine then you could call it a infiny or something..

SHHHHHHHHHH everyone!
The Icemark speaketh!
Seriously though, damn he knows everything!
I got to drive a GTUs last year and loved it. The owner had a full RB exhaust and it was bone stock from the factory with no options. It's become an inspiration for me in moding my 7... Even though I have an 87 GXL with every power option known to man.
I think some GTUs' out there with power options (especially those with sunroofs) might be hacks. You can buy the decals off Victoria British for $30 each. I personally would love to take an 89 or 90 GTU, beef up the suspension and slap a GTUs sticker on it.
Here's my Question: How hard would it be? Other than that special differential and everything else on the sticky thread, is there any other GTUs specific parts? I think I wouldn't even have to worry about getting specifics right because we have alot of people who claim to have a GTUs w/ power options. I've also noticed all the one's I've seen have a black interior, is this standard on the GTUs?

I checked that out and all it had were the exterior colors. That was still surprising though, there were only three offered.
Also, there's something I don't get. You said in one of the first threads that the GTUs' were just a way to rebadge a few 89 RX7s. But in the later post you said that the GTUs was its own project of a 20B RX7 which later dropped the motor but still made production.
If the GTUs' were just rebadged 89 RX7's, were they cars that were waiting at the factory for orders to go to delerships in the states but then got too old and were rebadged (and had a new diff installed). Or were they unsold 89 cars at dealerships that were then given back to the factory (or Mazda's California HQ ) for refitting and rebadging?
If it is just the remains of a dropped 20B project, why doesn't it have any resemblence to the concept? It doesn't have wide fenders, non retracting headlamps and it has a different diff that (if it was in fact intended as a "band-aid" to make up for the lack of a 20B) wasn't on the original concept?

Hmm, could have swore the interior colors were there too... my bad

No, I said the 90 GTUs (which there were a couple hundred) were re-numbered 89 models. Not enough dealer orders, but Mazda had already overbuilt the capacity in 89. Because there were not enough orders before the 89 production year expired, they just re-stamped the remaining 89 GTUs models as 90 model year. There is a strike out on the firewall VIN of every 90 model year GTUs that I have seen that changes the model year only.

If it is just the remains of a dropped 20B project, why doesn't it have any resemblence to the concept? It doesn't have wide fenders, non retracting headlamps and it has a different diff that (if it was in fact intended as a "band-aid" to make up for the lack of a 20B) wasn't on the original concept?
The picture is not from Mazda, but rather an artists mock up, based on what people were suggesting the car would have. I suspect that it was also cobbled together from pictures of the car being tested in the american southwest since the wheels were dead on. Of course since Day one people have been claiming the S5 models have wider fenders both front and rear... of course real enthusists know that wider fenders never came on the S5 models... yet people still claim they have them.

According to both Jack Yamaguchi and Isao Tohada (the later, I met last year at 7 stock) The 20B project started back in 87. The silver 10thAE versions being the first one to get it (as a side note, the silver 10thAE models with the 20B did not have the Turbo hood, but rather the scoopless non turbo hood and polished chrome wheels). Isao Tohda (Planning/Layout engineer when he first joined Mazda) led the project. His next project was the GTUs model. With the Normally aspirated 20B making simular power to the Turbo (but better torque). Again because of cooling issues and poor mileage (and according to Jack, a questionable gear box) Mazda management decided not to spend the money required to make the 20B work in the GTUs. In Isao Sans words," the GTUs, my first production car, fizzled in the market - not enough power and the low gearing we used to disguise the problem resulted in poor fuel economy".

His next project was the front packaging for the 3rd gen RX-7, including the cooling, aerodynamics, and performance evaluation. Intresting he told me that the only reason the FD was pulled from overseas markets was because of poor sales related to price, not emissions or safety or insurance rates as is often suggested. He blamed the overly expensive twin turbo engine for the blunt of the cost (of course that follows my opinion that the FD would have never disappeared from the US market if they had built a cheaper non turbo version of the FD- something that most FD owners consider blasphmeny)

After that he worked on the Amati flagship sedan that was to be powered by a new Mazda built quad cam V12. Of course that project burst and was cancelled in the Depression of the 90's.

Isao San, was also one of the project managers for the FE (RX-8).

I guess you could say Isao san was the father of the now famed GTUs.

In all honesty, if I found a GTUs, I would build a NA 20B for it, and shoehorn it in, just to build what Mazda should have. There is nothing special about the car other than that history, and nothing that will command a limited production status today. maybe in another 20 years, but otherwise its is just a intresting footnote and look at what manufactures and engineers are forced to deal with when marketing and sales commands the production.

Japan's currency peaked in strength around 95-96, the same years when sales of expensive Japanese sports cars really tanked, when Nissan almost went under, etc. With such a strong currency it makes imports expensive in the US market. I'm not sure an N/A FD would have been cheap enough.

Makes sence, it would explain why the supra was droped from production, and why many japanese companies have assembli plants in the USA..
