Working on a 2004 with SAI.
Found a lower mile motor with NO SAI. Given the recent experience of head gasket and head bolt stripping issues I've had I'd like to risk it and instal an "untouched motor". Just as much risk either way. I'm out of time and out of parience if not money.
So can the SAI be injected further down stream? It won't be as effective with emissions as it would be right at the exhaust valves of course - but will the o2 sensors still sense enough additional flow? Anyone done this? I know the sensor looks for flow, and it should be running in open loop at this point so it *shouldn't* be detecting actual gasses content. This leads me to believe it would work..... I've been wrong before though. Ha ha.
Easy to weld a fitting at the Y area or so.
Yeah - I have crazy ideas some times. And before anyone says it, I know the head should just be swapped but if you had ANY idea what I've been through with old blocks and weak threads you'd understand I just need a runner I can instal and chance it.
