ZN6 & FA20 specs, casual discussion

[Jonny Rochester]

The Toyota 86 repair manual went online today 8/6/12, viewed only by dealerships.
I am not going to copy it, but will put up random facts I find in it.

All the model codes, VIN, paint codes etc are carried over from Subaru. So they do not make sence or follow the same logic as Toyota codes.
The basic model code is ZN6. (Subaru is ZC6).

In early Toyota material, (followed by wikipedia etc) they were calling the engine "4U-GSE". However I am pleased to see they have dropped this and the engine is just called FA20 by both Toyota and Subaru.

The FA20 have VVT on both intake and exhaust cams. From my quick calculations the intake cam has duration 255 degrees, and the exhaust cam 252 degrees. (For reference, most normal cars have cam duration 240 degrees).

The 4 cams act on roller rockers similar to other current Toyota engines like 2GR-FE and 2ZR-FE. It could be a weak link for a high rev modified setup, time will tell.

The coolant is blue, and lasts for 11 years...

The sound tube maybe the most random part of this car. I'm told the new Lexus GS350 has something similar.

Some nice info.

With the sound tube, where does it end up inside the cabin? Do you know if we can order the toyota badge that covers the subaru stamp on the inside of the front fenders? I saw something available in the uk, wonder if its available here?

Also are you able to see if the boot has a mat to cover the full size spare? Some people say it has a mat standard and some say it is an optional extra due to the standard mat having a giant hole cut out for the spare :/

from what i saw yesterday in person the gt version has a moulded plastic rear trim that covers the full size spare in the boot, has an 86 logo in the center

Are the calipers the same size from GT to GTS ? Is it only the actual rotor which is sized larger in the GTS ?

[Matt]

Yeah

10. Toyota 86 has two brake packages

New Toyota 86 has two grade-specific brake packages to suit the 16-inch wheels on 86 GT and 17-inch wheels on 86 GTS.
86 GT has 277mm diameter ventilated front discs and 286mm diameter solid rear discs.
High-grade 86 GTS has 294mm diameter ventilated front discs and 290mm ventilated rear discs.
Both have aluminium callipers and a lever-type parking brake.
The brake response and vacuum booster have been fine-tuned to provide precise brake modulation

The GTS has these additional features..

Bigger Brakes / 17" Wheels
Leather-accented Front seaths with Alcantara fabric inserts
Heated Seats
Dual zone cliemate control a/c
Aluminium pedals / scuff plates
3 Spoke Steering wheel
6.1" LCD Touch Screen with Sat Nav
SD Card Slot
Paddle Shifters if auto
Digitial Speedo
LED headlights
Push button start
Effectively a Shift Light


Interesting that it has electric power steering..

Do the GTS only come with the red inserts on the seats, or can you get them optioned with just black?

[dove grey 64]

from the one i drove yesterday the standard gt also has red/black seats, just made in cloth.
also from what i saw the gt brakes are more then adequate, never once did it feel under braked

I like how the tacho will turn red like a shift light does on the GTS models.... Is enough to catch your attention unlike those autometer ones of the 90's which blinded the car behind you...

Some more random stuff. All the parts and repair manuals and owners manuals etc can be looked up at dealerships. If someone wants to know something, find a part etc, I can look into it.

All the part numbers are 10 digit Toyota numbers, but the first 2 characters on 90% of the parts are SU.
eg. SU009-00352

Service intervals maybe 15,000km... (in my opinion too long. Most toyotas schedule is 10,000km).

The handbrake uses a big drum brake. Not a crap drum brake like the Camry. And not a levered brake caliper like the AE86 and ZRE152.

The "D4-S" and engine ECU are Denso. All the fault codes are regular Toyota style numbers. I suspect the entire electrics (elect steering, keyless entry, VSC, etc) are Toyota/Denso. People once talked of the late Subaru ECU being "open" to tuners. I suspect the electrics and ECUs are more Toyota than Subaru, and probably fairly hard to crack. The first thing I would wait for is a piggy back ECU to raise the rev limit. (Imagine big cams, limited VVT, rev to 10,000rpm. OK, maybe 8500rpm)

The brake pads from Toyota come in 2 different friction compounds.

The manual gearbox is called TL70.

The standard camber on the front is zero degrees. There is a adjustment bolt availiable to change this a bit, as with most cars.
The caster is 5.9 degrees.
