So I know the JDM GTE has smaller turbos and less fuel stock but can the JDM internals handle as much power as a USDM GTE(with supporting mods of course)? I'm talking about something along the lines of a GT47 with supporting mods on both, will I get close numbers? I seen a thread here where a guy made right under 700whp on a stock USDM GTE with a GT47 and supporting mods and was wondering if it can be done on a JDM one.
Thanks

the JDM turbos are limited as to the boost they make, but they spool faster.

Here's the info you need, otherwise the rest of the engine is the same (except EGR). JDM turbo's are bigger, they just have weaker turbines due to them being ceramic and smaller wastegate. Rebuilding JDM's steel is far more worthwhile than wasting time rebuilding USDM's.

All this info is from mkiv.co.nz

CAMS: JDM Inlet 224deg 7.8mm lift, USDM inlet 233deg 8.25mm lift
Injectors: JDM 430cc high impedence, USDM 540cc low impedence
Airflow: JDM MAP sensor, USDM air flow meter

Turbo's: JDM CT20A ceramic, USDM CT12B steel
turbine size: JDM 60mm/48mm (inducer/exducer), USDM 52mm/44mm (inducer/exducer)
Compressor Size: JDM 62mm/39mm (inducer/exducer), USDM 58mm/39mm (inducer/exducer)
Scroll area (mm^2): JDM 600, USDM 740
A/R ratio: JDM 0.42, USDM 0.53

traction control: JDM ETCS, USDM TCS
