can someone tell me the difference between a 1jz and a 2jz

2jz is a 3.0L and the 1jz is a 2.5L
1jz has 276hp & 268lb-ft of torque
JDM 2jz has 276hp & 318lb-ft of torque
American 2jz has 320hp & 315lb-ft of torque
Someone said that the turbos on the 2jz are better but as far as I know that is only true for the american models. The JDM models come with ceramic turbos
I have gone through this same process but I think that in the end the 2jz is the better engine
It was built off of the 1jz and so they improved on it plus the extra displacement means it will take less to yield higher horses and you can peak it higher
If you decide to go for the 2jz it will definitely cost you. Especially if you want a manual tranny
This knowledge is just based off of what I have learned while trying to figure out myself if the 2jz was worth it. In the end I decided I just wanted to go for the best engine possible and so the saving began. lol
Good luck

By the way, I can't even find an American 2jz for sale on Ebay. Only the JDM versions tend to go but it's an AWESOME engine
