I've got no EGR system

rinso · 02-01-2009, 08:21 AM

Due to a blown head gasket I've taken the head off my 7M-GTE to discover it has no EGR cooler, which is a plate on the back. I've also got no EGR valve. Instead I have a little plate blocking off the exhaust hole where the EGR cooler would cover effectively ignoring the EGR system altogether. Does anyone know of any reason why I shouldn't keep this setup? I've driven my car for two years without a problem, besides the headgasket. That was always going to happen though.

If you've got a JDM ecu, no problem, as JDM engines didn't have the EGR system. It's only when you've got a USDM engine or an ecu which is setup for an EGR to be present that it's a real problem.

It is indeed a japanese import, so I guess I am good to go! You little beauty! Thanks for the input.

Just cause the engine is JDM doesnt mean the ecu is. Check it.

So if I wanted to block off my EGR I would need a JDM ECU not the U.S. spec ECU?

^ Yes. Probably easier to get your egr working.
