Bungs: Revised (KA-T)

[matt0941]

OK I am getting bung crazy tell me if I don't need any of the following or have their positioning wrong for my KA-T setup. (EGR is optional but I may want to run it later on)

EGT (Exhaust Gas Temperature) Bung in the #1 cylinder runner of the exhaust manifold

EGR (Exhaust Gas Recirculation) Bung in the downpipe

o2 Sensor Bung in the downpipe

wideband o2 sensor Bung (for dyno tuning)

Your comments please.

ummm move the egt to the downpipe. You are looking for a difference in temperature here, not the actual temperature itself.... maybe for tuning purposes u need the actual tempperature, but it could be approximated. Plus the exhaust manifold (especially cast iron) is not something i would mess with and it costs ~3-4 times more than yer dp (in case u screw it up). Oh and u must have egr unless u are ok with check engine light always on and emissions being much worse. Its definately much easier to get a bung for the egr on then mess with the sensors...

and why would you need 2 sensor bungs? I'd guess you can use the o2 sensor hole when u tune with the wideband sensor and then replace with a normal sensor once your done.... or you plan on running 2 sensors?

heh heh heh...BUNG

Lol

But thanks for the reply kreator, as for your idea of taking out the o2 sensor and replacing it with the wideband for tuning, would this work?

if it did it would save me some time, can anyone else comment?

thanks

i think it should... i'm not sure if your car will run on just the wideband sensor alone (should, but i don't want to mislead u). As for fitting, i think they all use the same thread pattern (my 240 sensor screws in volvo 740 downpipe). Plus if you drill 2 holes, you'll have to be plugging one up after you are done.... doesn't sound right.
