Early Production Turbo A?

[Jeff Lange]

Yeah it seems that due to the way the EPC lists Turbo A cars, it's assumed that they were all made in 1 month, because they were the 89+ style cars, they just grouped them with the 89+ catalog, even though they seem to have been producing them essentially whenever they felt like it. Seems like they were made all throughout 1988, according to frame numbers.

Very weird.

EDIT: Beefy, yes, every Turbo A I've seen, no matter what production it was, has the same body pieces (wide body, updated parts) as the newer cars.

Some other interesting things are that the car doesnt have a 180kmph speed limiter The only change to the ECU that is obvious is a HKS fuel cut defender. Also it has the "serial killer" door locking at 20ish kmph feature. Do other turbo A owners have the same features on theirs. Wiseco?
Very informative thread guys. Ty for awesome input Jeff and JDMMA70

Here's a theory at the start of 1988 excluding the first and the last week of the year, Toyota could've made 10 turbo A's a week. At the end of 1988 they would've made 500. It would explain why some have different harnesses.

Do you have the part number from your ECU by chance? I'm very curious what it is.

what does the "BLMXZ" mean

Turbo-A nomenclature..

How many Turbo A's were built?

^not enough.


Tangent thought: I seem to recall a thread on how on the regular supras ECU's are identical, however a simple resistor is placed in a different location to change what its meant for. I wonder if this is possible for the Turbo A ecu's as they are MAP based (IIIRC). That would be a sweet mod!

That would be awesome!

500 turbo A's ever made.
That could be speculation however, the rules of group A is that a minimum of 500 production models are availible to the public. So could be more.

I wish turbo A owners cared enough to register their cars so we could have it all documented; specs and model numbers, etc..

To clarify (regarding the mod possibility), I mean using our own existing ECU's and replacing the resistor so if becomes a turbo-A ecu.


And I wouldn't be surprised if half of those 500 are in junkyards because people didn't realize what they had.

We know for sure it was only 500.
Specs of the car they were all Black Hardtops (Colour Code 202, with all the Turbo A badging) with Grey leather interior. Had the standard Pre89 radio and manual A/C controls (A/C was optional). Bilstein shocks, standard springs. The seats were manual crank seats no power. Momo shift knob, and momo steering wheel. Also had black sawblades. Yellow foglamps, the headlights also had yellow bulbs. Obviously all of them had the turbo A (group A duct), and the 89+ face lift. All had R154's and the 3.73 LSD. The engine was a standard 7MGTE with a MAP based ECU (so no AFM). The 3000 pipe was larger and didnt have the (3000) lettering on it. The throttle body was 65mm. The intercooler was also larger, had to use the 1JZ overflow tank for the intercooler to fit. The turbo was also special, it was CT26 based but i dont know much about it but there is an "E" stamped on the housing. It flows better than an upgraded CT26. The car put out 270 PS when new, at the time it was the faster Japanese production car ever made, until the R32 GT-R's release. The tires that came standard on the car were Bridgestone Potenza RE71's. The brake rotors had extra cooling vents around the hub. turn signals were slightly darker than OEM JDM turn signals. The stock air cleaner box was metal instead of plastic. The oil cooler was placed in front of the intercooler behind the turbo a duct. The recommended tire pressure was also different.

ive got more pics but that should be enough

Most of the Japanese Articles i have on the turbo A all state that production was limited to 500 cars order only.

 

[IJ.]

take 2

How do you know "for sure" that there were only 500 made?

Most of the homologation specials were built to order and if the demand was there most companies would just keep turning them out from the cars on the regular line, I'm not saying Toyota did this just that most of the manufacturers that were running Group A cars did at the time.

 

[JDMMA70]

^ my response is right above yours lol (i cant say for sure but im pretty positive going off the articles i have)

 

[IJ.]

Bit hard to know for sure as my understanding is the VIN's aren't consecutive, I'm just going on what everyone else did at that time, the "rule" was a minimum of 500 but no maximum, again this was all a bit flexible and there were quite a few of the local cars here that didn't quite get the full spec but were still sold as the special they were meant to be... (also a few cars never made the numbers but were allowed based on projected production numbers, I worked as a Fabricator on one of the big teams here in the late 80’s)

 

[JDMMA70]

Toyota released in 2002 supra memorbilia on CD's you may be right there might be extra cars out there. But according to the info on the CD's production was only 500 cars

 

[IJ.]

Guess it would have depended on demand at the time, can't see any manufacturer stopping at 500 if they have orders for more but as I stated that wasn't the case with many of the other brands they struggled to make/sell 500

Having said that I don't get the whole Turbo A fascination unless it's a Concours level car, change anything on it and it's not "unique" and becomes another modded Supra.

Id love to own a completely original model. I wouldn't even mod it, that's one car I wouldn't be able to bring myself to mod.

Wish more people thought this way <golf clap>

I guess im what they call a Supra Enthusiast

Adding a resistor won't change the ECU to a MAP sensor input. A MAP sensor uses a piezo sensor. The karman would still have the same frequency, but the amplitude would be lower with a resistor.
