Is it possible to replace Oil pressure gauge with wideband reading gauge? I will have aftermarket gauge for Oil press reading at the other place.

 

if its small enough and you hook it up correctly...idk why not

 

Yes people have done that, search the archives and you will find out how.



Later

 

Yeah, it can def be done. Though, unless your stock sender is broken (and you REALLY don't want to replace it..) I think getting an aftermarket Oil Pressure gauge is pointless. Just keep the stock one in the stock location, and add the Wideband A/F gauge in the extra position.

 

I've seen quite a few screwed up oil pressure gauges. I've been seriously contemplating replacing mine with a Stri oil pressure gauge (and the water temp too)

 

Yeah, a lot get screwed up, though (correct if if I'm wrong) 9 times out of 10 the gauge is fine, it's just the sending unit that's hosed. Replace the sending unit and the stock pressure gauge is working again!

Mine still works, and I recently hit 104,xxx miles (DDing her adds up!!)

 

my car is over 126k on it, oil gauge is poop, even with new sender, why not replace it with a gauge with actual resolution and 270 degree sweep? There is no reason not to especially when there are more than a few out there that match the stock gauges (both black faced and y2k+ white faced)

 

I've done it

 

^ that is awesome.

The only thing I find particularly useful for the stock oil pressure gauge is the oil level idiot light.

 

Looks awesome man! Thanks for sharing. I have Innovate DB gauge... I think it should fit as well.
A/F is a good diagnostic gauge... It gives me a little peace of mind if at least A/F ratio is right.

 

Nice write up.
Mahjik do you know anything about VEI System gauges? BTW They look better then SPA gauge in my opinion.

 

I got a new oil pressure sender and gauge installed in my car. When I compare the stock and aftermarket gauge, its like night and day. The needle for the stock one shows a lower pressure than the new one. It also seems slower to.

As to what Gordon said, yea I think thats about right. The pressure gauges isn't to important, only the fact that it goes up with your RPM. Having said that, I installed an aftermarket one just because I'm paranoid. To be honest though, I don't really keep my eye on it. My eyes are always on water temp and sometimes oil temp.
