I think you failed to realize he is installing this on his 93 DX. it doesn't matter TOO much where he puts the O2 sensor. there are 2 O2 sensor bungs in the 96+ headers because the 96+ DX uses 2 (pre-cat, aftercat). He doesnt need a simulator or anything, just find a threaded plug for the first O2 bung and put your stock O2 sensor in the 2nd bung. As far as fittement goes on the head, im not sure, but it will most likely bolt up just like all bseries heads have the same exhaust bolt pattern. You can reuse the stock bolts and same for the stock header donut gasket.klungemonger said:Actually that's not correct. Someone might have told you that the two holes are for the 2 sensors but it's not true! On the 96-up DX motor, both sensors are up in front so it still won't reach the second sensor hole!!!
Not only that, but the 2nd sensor is an after-cat sensor so even if there is a spot for it on the header it will give improper readings to the ECU since it's in front of the cat instead of after it where it belongs. You need an O2 sensor simulator or a cat with teh sensor bung in it.
Oh yeah. I didn't fail to realize, I just forgot! Lots going on here, can't keep everything straight these days. I just saw the "97 DX header" thing and ran with it.b16a ferio said:I think you failed to realize he is installing this on his 93 DX
