I know the bore and stroke are different. I would like to know what else is. I didnt see any sticky or searches about it,.

bigger turbos, injectors, cams, head flows better just a few

Besides those things cuz those are easily upgradable.

Head flows better? Is that due to a p&p and larger valves?

 

[The Reaper]

no its just designed better but larger valves im sure helps it

2.5L vs 3L is the biggest difference.. (sounds like your trying to see the differences in power output)

Are you comparing a 1JZ to a Japanese or a US/Export spec 2JZ?

The 1Jz as well as the JDM 2Jz are only 280HP Due to the Gentleman's agreement between manufacturers in Japan.

I think everyone else has already gone over the differences.

I think the 1JZ Stock has a Higher Red Line / Rev Limit

1jz probably makes a little more then 320 hp at the crank. 280 wheel hp is average for a 1jz.

I wonder why Toyota underrated the engine the way they did. Trying to slip under the Manufacturers agreement maybe

In Japan, it was never in writing. Just a gentlemen's agreement. I asked my wife about it and she explained it to me that way (she's 日本人　or in romanji nihonjin).

I understand that it was. I just thought they truly did stick to it.

No way! lol Supras and Skylines whomped that agreement into the ground.

Van what was that first word? Romanji Nihonjin = English lettering system for Japanese characters and the Japanese word for Japanese person. So I'm kinda confused there
