Difference between JDM 13B Turbo and US 13B turbo?
Hi, am wondering what r the differences between the JDM 13B turbo(S4/S5) and the US 13B turbo(S4/S5)? Thanks
|
the ecu and bac are different, the jdm engine has less emissions equipment. search
|
So the housing, rotor, eccentric shaft are same.... So really the only difference is the ECU and the BAC. That good to know.
|
One is Rotary Turbo With Intercooler.
The other is 13B Intercooled Turbo II. |

brake booster hose location is different due to being RHD
|
all JDM turbo engines usespark plug spacing on the housing same as the US s5 T housing
|
Ok. Thanks or everyone inputs.

So I plan on buying this s4 jdm short block are saying I wouldn't be able to reuse my s4 Ngk plugs and would my intake and turbo manifold bolt up to it?

Jdm also doesn't have egr

the japanese engine ,, and the oz s4T engines have spark plug spacing either side of TDC as your s5 engine s4 and s5 turbo jap and oz engines also all share the G middle plate ( larger primary port AFAIK found only in the s5 in the US ) there is also detail differences in the manifolds ( use your US ones if in doubt ) s4t in oz = external EGR valve + ( G middle plate = internal EGR) s4T in jap= no external EGR + ( G middle plate = internal EGR ) s4t in US - external EGR + ( x? middle plate ) s5T - everywhere - no external EGR ( G middle plate = internal EGR ) |
Thanks for the info!!!!
