Hi all... I'm looking for my best path. Here's my situation:
I have a JDM EJ25 without EGR. It came with AT and many accessories. (no JDM ECU though)
I'm trying to put it in a 1999 Outback Wagon. Due to some engine swapping previously, I do not have the original EJ25D or intake manifold.
My state does not do smog tests.
I could live with the engine light on, but prefer it being off.
Option #1 - Get EJ25 intake manifold used with EGR stuff, $$$. Drill EGR port, being careful. This should make everything legit? No codes? Runs right, good mileage?
Option #2 - Get EGR stuff (what do I need?) and tuck it under the manifold. I read that this is enough to make the ECU happy and not throw codes? Good mileage?
Option #3 - Do nothing, don't buy or hook up any EGR. ECU throws codes. Would mileage suffer? Would it run right?
There are lots of threads, but can't see one that addresses these options. My main concern is making it run right. Second concern is not spending more money. Third, codes / engine light.
Thanks for any ideas.
