1jz Gte 2.5l Twin turbo
 

jdm 1jz Gte 2.5l Twin turbo anyone know the Spec. Hp and Torque ?
swap in 93-95 SUPRA anyone know ..... ?

As you may know, this engine never came from Toyota in the jza80 (Mkiv Supra chassis). As a result, you're likely to encounter differences in the motor mounts and the oil pan (at the very least). Worst case you'll also have problems associated with putting an engine from a RHD car in a LHD, such as interference between the intake manifold and steering column.

In addition the 1jz-gte turbos are parallel (not sequential like the 2jz-gte), so you'll have to run them in your Mkiv as you would a single turbo.

You'll also run into all of the standard n/a->turbo conversion issues such as fueling, ignition, etc. Which ecu were you planning to use with the swap?

I don't know hp&tq for the 1jz-gte offhand but I'd guess 320*(2.5/3)=266.7hp at oem boost levels.

Imho this is a questionable idea at best, but if you do decide to proceed please take notes and lots of pics to post here! :)

i just find out today that , the engine basic exactly the same .my friend drop ir in his SC300 , IT sound weak maybe because it an automatic . ebay people listing is 280 HP 2.5l TT , and what get me confused is that 2jz GTE from the Soaror 280 Hp automatic .

Since the engine is turbocharged, horsepower depends on boost level. You could probably call a 1jz-gte a 350hp 2.5l tt and still be accurate, technically speaking.

Since the displacement is about 17% less than a 2jz-gte, you can expect about 17% less horsepower at the same boost level.

jdm stuff
