Diffrece: USDM vs. JDM turbos?

[Sandy sx]

Is there a difference between the US and JDM turbos? A/R.? Compressor wheel size?

[Zak427]

i heard it mention that there is a difference....but it's unlikely.

I know the auto's had a slightly smaller compressor, other than that I'd assume they are the same

Anyone know what the stock US. A/R is? Im just trying to figure out what i got here. Thanks.

.63 A/R turbine housing was standard on 5 speed models. Garrett no longer produces the Automatic version, but the 5sp turbos will work on both 5 speed an Automatic models, as well as the .54 A/R (automatic) turbine housing can be swapped over from existing turbos without a problem as long as it isn't damaged.

No difference between the usdm 5sp and jdm 5sp. I can't verify for the automatic because I only have 5sp turbo's infront of me.
