Supra Specs and time frames?

[glish_dreams]

I was just wondering the spec on all GENs .. like HP torque .. Valves,Cams, liters, L6 or V6 .. and what GTE GTTE means.. i understand the T TT is turbo twin turbo.. im guessing E is engine .. and i was wondering the GEN time frames..
a friend of myne told me in 85 ..that was the first year supra was just supra.. not celica supra... is that true.. its my bday..and it means something to me..and id like to have a 85 if thats true..
motors i no ..7M, 1JZ, 2JZ .. GE GTE GTTE..

thank you...

[glish_dreams]

i found most my info on another post.. thats crazy and amazing that it was always L6



MAN... MAN! WHAT THE HECK! LOL


1979-80: 4M-E, inline-6 2.6L SOHC 12-valve engine
1981: 5M-E, inline-6 2.8L SOHC 12-valve engine
1982-86: 5M-GE, inline-6 2.8L DOHC 12-valve engine
1986.5-1992: 7M-GE, inline-6 3.0L DOHC 24-valve engine
1987-1992: 7M-GTE, inline-6 3.0L DOHC 24-valve turbocharged engine
1993-1998: 2JZ-GE, inline-6 3.0L DOHC 24-valve engine
1993-1998: 2JZ-GTE, inline-6 3.0L DOHC 24-valve turbocharged engine

That's for North America Only.

In Japan the Supra had a Turbocharger earlier, though it was called a Celica XX from 79-86, not a Supra. The 82-86 Celica XX/Supra had many more engines than we got (we only had the 5M-GE). Worldwide, the MK2 had the 5M-E, 5M-GE, 6M-GE, M-TE, 1G-GTE, and possibly others. The M-TE and 1G-GTE are both turbocharged 2.0L inline-6 engines. The 1G-GTE is twin-turbocharged.

The MK3, worldwide, had the following engines: 1G-E, 1G-FE, 1G-GE, 1G-GTE, 7M-GE, 7M-GTE, and 1JZ-GTE. The 1JZ-GE was never sold in the Supra, and the 7M-GE was NOT sold in the Supra in Japan.

The MK4 only had the 2JZ-GE and 2JZ-GTE, though in 1998 the 2JZ-GE got VVT-i, and in 1999 the 2JZ-GTE got VVT-i as well, but we never got the Supra in North America past 1998. It was sold in Japan until 2002.


Hope that helps a bit.

What The **** is an L6?

The VVTi 1JZ-GTE's use a single turbo but are only found in the 97+ JZX100 Chasers & 97-00 JZZ30 2.5GT-T Soarers. There are no VVTi 1JZ-GTE's with a factory twin turbo configuration.

The VVTi 2JZ-GTE was still twin turbo but incorporated the same overall changes otherwise when it went VVTi. (MAF, wastespark, etc)

2JZ's always had twin turbos (and of course, N/A's) and 7M's had a single turbo (and the N/A as well). There was never a real (see: Factory) '7M-GZE' as some pictures around the web suggest. As for TT MA70's (Mk3 Supras), The only ones in existance were not offered stateside. The ones that were offered were either the 2.5L TT (1JZ-GTE) engine or the 2.0L TT (1G-GTE) motor not the 3.0L 7M-G(T)E motor we're all used to seeing.

(I'm just throwing all this out so that hopefully when the next noob wanders into the forum, they'll search and find this post. Obviously it's not all On Topic info.)

There are several TT manifolds in existance for the 7M, however due to the potential of a larger single, it's often the chosen power path. I know blitz made one, HKS made one, the 5M TT manifold which bgreiger has is from HKS IIRC... The authentic ones (not clones) are rare to find in most cases.

For future reference, this site has a lot of information about the import and export models of the Mk4 Supra: http://mkiv.supras.org.nz/specs.htm



As far as names are concerned, 2JZ-GTTE is really a nickname, the actual motor code is 2JZ-GTE regardless of how many turbos it has. Since the topic has arisen, here's a primer on Toyota Enginge Codes:



Toyota engine codes are split into two sections:

1. Before the dash - Which represents the family or series of the engine (i.e. 7M-GTE.)
2. After the dash - Which represents the engine features (i.e. 7M-GTE.)

#1 - Before the Dash:
The numbers represents a revision of the bottem end for example bore, stroke, and block.

• A = A series engine, 4 cyl gasoline. Family of inline-4 configuration engiens with a displacement ranging from 1.3L to 1.8L. Series began in the late 1970s with the 1A, a SOHC with a displacement of 1.5L. In 1998, the 7A-FE was the last A engine in the family, a 1.8L DOHC engine that produced 115 HP.
• AZ = AZ series engine, 4 cyl, gasoline. Family of straight-4 piston engines. Uses an aluminum engine block & aluminum DOHC cylinder heads. Has MFI FI and 4 valves per cylinder with VVT-i and features forged steel connecting rods.
• C = C series engine, 4 cyl diesel.
• G = G series engine, 6 cyl gasoline, family of straight-6 piston engines produced from 1979 through 1998. Only a single displacement, 2.0L was produced in this series. All were belt-driven OHC engines, with multivalve DOHC and even variable valve timing added later. These were used as a lower-displacement alternative to the more-common M family straight-6.
• JZ = JZ series engine, 6 cyl gasoline, family of straight-6 engines.
• K = K series engine, 4 cyl gasoline, pushrod. Family of straight-4 engine produced from 1966 through 1998. 2-valve pushrod design, a rarity for the company.
• M = M series engine, 6 cyl gasoline, family of straight-6 engines used from the 1960s through the 1990s. All M-family engines were OHC designs with a chain-driven camshaft giving way to a belt after 1980. The 4M-E was notable in that it was the first Toyota engine to be equipped with fuel injection. The M family was commonly found on the large Toyota Crown, Celica Supra, and Supra.
• MZ = MZ series engine, V6 piston driven, aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses MFI fuel injection, has 4 valves per cylinder and features a one-piece cast camshaft and cast aluminum intake manifold.
• NZ = NZ series engine, 4 cyl gasoline, family of straight-4 piston engines. The 1NZ uses aluminum blocks and DOHC cylinder heads. It also uses SFI FI, and has 4 valves per cylinder with VVT-i.
• P = P series engine, 4 cyl gasoline, family of straight-4 engine produced from 1959 through 1979.
• R = R series engine, 4 cyl gasoline. Family of straight-4 engines produced from 1953 through 1990. Designed for longitudinal use in such vehicles as the Celica and Cressida. OHC versions featured a chain-driven camshaft.
• RZ = RZ series engine, 4 cyl gasoline, family of straight-4 engines usign a cast iron engine block & aluminum DOHC cylinder heads. Has MFI FI, 4 valves per cylinder and features forged steel connecting rods.
• S = S series engine, 4 cyl gasoline.
• T = T series engine, 4 cyl, gasoline, family of straight-4 engines. Began as an OHV design, but a chain-driven DOHC variant came later.
• U = U series engine, series of flat-twin engines produced in the 1960s and 1970s.
• UZ = UZ series engine, 8 cyl gasoline, V8.
• VZ = VZ series engine, 6 cyl gasoline, V6.
• ZZ = ZZ series engine, 4 cyl gasoline, family of straight-4 piston engines. The series uses an aluminum engine block and aluminum DOHC 4-valve cylinder heads.

Here is a different, more simpler, summation:
(All engines cast iron block, alloy head unless otherwise mentioned.)

• A series (inline 4, belt, 1.3-1.6L, 1978-): Corolla FWD/RWD, MR2, Tercel FWD

Jesus, at least you searched.

[glish_dreams]

holy ..thats alot of info.. THANKS..

oh L6 is inline six.. its not I6.. thats the incorrect way to show it.. at least thats what my college teacher said...

[repinS]

Yeah, the technically correct way is L6, it's the convention because people can confuse "I6 for "16".

But I (and many others, including Jeeves) use I6 in real life.

[glish_dreams]

well non the less the information was great and i printed it out for safe keeping.. thanks.

[glish_dreams]

(Engine uses TTC-C, TTC-L or TTC-V)

whts those stand for.. are they something for emissions like VVTL

They are all types of emission controls in Japan.

[bowlofturtle]

we have the 230hp on the crank. but what are most of you guys putting to the wheels on your baseline dyno's. generally its about 15% or so with a 5 spd. but i wanted to get idea how much it is on a supra.

[Jeeves]

Never did a basline dyno, sorta wish I had. My first dyno was 262/315 @ 9psi.

Intake/Exhaust/Boost Controller/Fuel Controller. Timing @ 14ºBTDC.

[PpDdAiDdDdYy]

Can I put this supra info on my website?

I'd prefer you put a link to this forum, but as it is the web and not my copyrighted information there's nothing I can really do to stop you from doing so.

Nice page with some good info, but not as explicit.

[PpDdAiDdDdYy]

IfI link to your page would you do the same for me? And what did you mean by its not as explicit?

[Jeeves]

It's not as detailed as information that can be found elsewhere. And what are you talking about a link trade? I don't have a website to put a link to you on.
