http://en.wikipedia.org/wiki/Toyota_JZ_engine

The 2JZ-GTE is an inline-layout, six-cylinder, belt-driven dual-overhead camshaft, air-intercooled, twin-turbocharged, cast-iron block, aluminium cylinder headed engine designed and manufactured by Toyota Motor Corporation that was produced from 1991 until 2002 in Japan. Development and evolution of the engine was, principally, a response to Nissan's relatively new and then-successful RB26DETT engine which had achieved palpable success in FIA Group A and Group N touring car championships, worldwide. Final development of the 2JZ-GTE was outsourced to German engineering firm Johann A. Krause Maschinenfabrik GmbH for refinement to meet production car homologation requirements set forth by the former All-Japan Grand Touring Car Championship.

The addition of twin turbochargers, jointly developed by Toyota with Hitachi, in sequential configuration had raised its commercially-cited output from 230 PS (169 kW; 227 hp) to the contemporary industry maximum of 280 PS (206 kW; 276 hp) at 5600 rpm.

Not sure how reliable this information is from wikipedia.

 

These Eurotrash fanboys never cease to amaze me with the amount of diarrhea that comes out of their mouths.

 

Degree your always making me laugh with your comments !! Hahah Plus having ODB as your avatar is just lol ...

Wiki is 100% wrong (not uncommon). The 2JZ was 100% designed in-house at Toyota.

OP, you are correct. And Yamaha also helped with the 2JZ head. You are also correct that your friend is a tool.

^^ this !

 

Yes, an iron block straight 6 was used in F1 cars in the '90s. Seriously, why bother arguing with him?

 

I've ignored him and kept my mouth shut. Just wanted to prove him wrong on one thing...

 

Looks like the 2JZ does have some German roots though according to Wiki. I wonder if anyone has further information on it?

 

He wasn't to far off, Johann A. Krause Maschinenfabrik helped with a big majority of the design. I believe he was also part of a few BMW projects.

It wasn't mass manufactured there though, but I believe some original test models were. But mass production happened over in japan after they figured out the cast molds.

 

I wish i could find it, But not too long ago there was a link to a You Tube video of the 2jz's being made and produced.Would probably clear up a lot of things

 

This is the video I think.

 

Awesome video dose anybody know if there's any more like it on the rest of production of 2JZ's or supras?

 

^Yes that is it!I do not know if that helps any, But pretty interesting though.

 

I guess the person who wrote the wikipedia article about the 2JZ development is/was neither working for the Johann A. Krause Maschinenfabrik GmbH ("ThyssenKrupp Krause GmbH" now) nor Toyota Japan.

A German who knows that company for more than 20 years wrote that he asked several employees, they never did any development or production for Toyota engines. In fact they never built any engines/transmissions/... for OEMs but they make/made production equipment for assembly lines.

 

I have asked them about whether they were in any way related to the development of the 2JZ and they reassured they weren't. That Wikipedia-Article is just plain bullshit. Why bother arguing with any ricers/fanboys?

 

the 2JZ is the greatest 6 cylinder engine ever made, thats all I know aih ^^

 

Sick Video I wonder when it was made and if they have stopped making them.

Also it seems like it was pretty recent as all the Robotic assistance to the workers.

 

im not expert, but them ppl in that thier video dont look german

 

Big difference regarding manufacturing, and design engineering. What you see in the video is the final product, everything has been engineered already, tested in one off situations, tweaked, and now being mass produced.

toyota nor bmw ever had an inline 6 f1 engine bmw only had thier inline 4 based out of the m10 engine, i beleive the op also wanted to know if the 2jz was produced in germany, which the video clearly shows that its made in japan, yes the design was outsourced and they probably hand made a couple of prototype engines, but it is a Japanese made engine, not german

 

Zombie bumping this thread. My friend that loves BMWs just told me that this Johann guy designed the 2JZ engine for Toyota. I'm trying to find information on it but having a hard time. I want to believe it was 100% made in house at Toyota of Japan, but I cannot find anything proving one way or the other.... and I can't really trust wikipedia either.

 

The head was done by Yamaha, which Toyota had some ownership in Yamaha. You could consider it subsidiary. Toyota did the block and crank, etc. in house. It's Japanese for sure.

 

The fact the fella said it was an F1 engine made me spit my food out, and roll on the floor.

Im one of the biggest 2JZ fans, but an F1 engine, it isnt ???

 

The 2JZ was 100% Toyota (No Yamaha or other 3rd party direct involvement).

Probably one of the only worthwhile things to come out of the MKV forum was clarification and corroboration of this MYTH:

@HellBringer is right, The 2jz is completly Toyota much like the 1JZGE is. Many people assume that the 2JZ is a continuation of the 1jz it is but not in regards to the head in that it was also made by Toyota.
