JDM Engine
Hello,
I did a quick search and found no answer for my question. What are the differences between the JDM EG 33 and the US spec engine? I emailed a question to the sellers and they say the engines are interchangable. They use the same ECU and Wiring harness. Any more knowledge would be wonderfull. Thanks... Dave

im not sure on the SVX but you might need to swap out the intakes... i know some JDM's are carb and fuel injection in the US

  A CARB on a SVX?! That would be strange to see.

Sorry to make a joke out of what is probably an unfortunate mistake and no offence intended.

All SVX engines are the same (except for the JDM twin-turbo police special
)The ECU programming is different, presumably this is to accomodate regional fuel differences. It is rumoured that the JDM cars are optimised for the 100+ octane fuel that they get in Japan. My JDM cars definitely run much better on 98-99 than the standard 95 we get here in the UK.

Engines are the same, the only differences are in the ECU. People like Silverspear have Open loop ECU's which do not function off emission standards and run on a basis of optimal performance for regions allowing it

What could that do for those of us in the US that don't have to worry about smog checks? Dan

The JDM ECU is definitely different. Note the incompatibility of LAN's chip, for example. Matt

I do not see a big enough gain to buy and ship an ECU from the middle east. not only will sourcing one be a HUGE pain in the arse but it will cost more than it is worth. The Stage 2v5 ECUtune would probobly be more worth your while. Additionally I am not sure how well that ECU will work with the USDM wiring setup and whatnot.

Also, according to a recent or semi-recent post I read from LAN, the USDM ECU runs the EG33 quite well with the O2 sensors unplugged. If I recall what he said correctly, the ECU ignores the lack of input from the O2 sensors. Apparently the engine runs even better without them.
