I did a search and didn't come up with much. Im going to be running nitrous soon in my 2.2L I want to have a Fuel Pressure and and Oil Pressure Gauge. Anyone know how to wire these up or what wires to connect them to? Or if its possible at all....I have a 05 Base 2.2L Auto Balt. Any help would be great. thanks!

 

Its possible. I believe the oil pressure gauge needs a hard line going into your engine block to get a little bit of oil. Not sure though

 

Ohh ok....Now how abouts would that work. Would I just run a line from the gauge to the oil pan? Or were would i run it to? Thanks For the help though

 

Matt doing your thing bro! if you need any help i got ya bro! youll be in 14's mabe!

 

hahaha thanks man. Do you know about any of this? that or do you think you could help with the nitrous install?? that be sweetttttt haha. But any info on these gaudges would be great!

 

you're really not asking a lot. generally, the turbo will need oil from the engine. since that is coming from the pump side of it, you can just T off of the high side to the turbo. it may not be 100% of the full reading, but you'll be able to keep an eye on it and make sure it doesn't drop. also, AFAIK the eco will report a drop in oil pressure on the stock cluster.

fuel... well, just pop a sender on the test port on the fuel... no drilled needed.

 

im gonna be running nitrous though . haha guess you misread it its cool though thanks for help. Im guessing i can still do the same for the fuel pressure

 

yeah, you're just reading pressure, you don't need to get fuel from there.

 

how does one go about putting a sender on the test port. haha sorry kinda a newbie when it comes to this. been doing my homework on the nitrous though

 

im bout to do the same but idk if i am getting all those guages...maybe they are needed....i do know that there is a pinout of the ecu for wiring on here somewhere that should help

 

you could get a oil filter adapter from greddy and they already have holes drilled and tapped, so you would just run a line from there that is what most do to get oil to there turbo setups, so you should be able to get a reading from there

 

Greddy doen't make either a relocation kit or an oil filter adapter for a Cobalt...unless you know something secret....

 

If you go to Autometers website they have a section that will tell you how to install a bunch of different gauges.

 

I think the pressure switch for oil is pic'ed as below w/the red arrow. It looks to be a bitch to get to, and you would have to tee off of it. Then you have the risk of creating an oil leak in a place that is tough to get to ....

 

Autometer.com does have some nice info...this is cut and pasted from it

Oil Pressure Gauge Thread Size
for 2.0 SC engine(s)
M12 x 1.75 , Use a # 2278, Oil gallery located on back of block behind large water pipe
(a 2278 from autometer.com is a Electric Temperature or Pressure 1/8" NPT to M12x1.75 adapter, Product # 2278)




Water Temp Location and/or Thread Size
for 2.0 SC engine(s)
Remove plug at bottom of water pump. Use a 12mm x 1.5 Auto Meter #2277 adapter (a 2277 is an Electric Temperature or Pressure 1/8" NPT to M12x1.5, Product # 2277). If using a short sweep electric temp gauge (uses a single wire sender), then you must use a #2259 sender. If using a full sweep electric gauge (with a 2-wire sender), the included sender with the gauge will work. Sorry, no adapters available for the mechanical gauges.

 

Good **** Man!!! There Is Definately Feel The Large Pipe Going To The Water Pump And I Can Feel The Plug In The Block That Need Removed To Screw In The Sending Unit!!! If ya'all want i'll do a "how to" when i install my guages...it will be for A/F and oil pressure!

 

That would be a very good how to...lots of pics a must....

 

Yeahhh that would be great. Would definatly love that Keep us up to date!!

 

i wonder if the same plug is on the LE5
