Alright fellas been trying to search info of 2jzgte's with auto trannies cause apparently its going to be a difficult task for me to get a motorset from Jhot from a soarer (1jzgte) my question is how much power can the 2jzgte auto tranny can hold without any upgrades to it, what can i do to the tranny for quicker response and for it to hold lot more power ? once all said and done i want at least 600whp out of my set up wether auto tranny or manual... if its not too much of a hassle to have an auto with that much whp then great... I know of a supra from houston with auto tranny making over 650whp with the tranny unlocked... i dont know what that means but i guess it could be done with the same auto tranny from the 2jzgte right?

 

you need a auto clutch kit, tranny cooler and torque converter if you plan on going above 400hp.

 

you will be looking at the built auto from boost logic.

 

That WAY too much power for the stock auto.

A Boost Logic built auto is a possibility. I would keep an eye on SC400TT's build. If his BL auto is able to handle ~600wtq from a TT 1UZ, then I would feel pretty safe with one. I have read that Club Lexus members have struggled with their reliability in some cases.

Honestly, the easiest way to ensure that you can hold the power is to go with a stick. The R154 five speed can handle 600whp.

 

please use our engine forum.

 

Sorry, anyone know of any other reliable sources to could provide me with a R154 tranny?
