Well guys I just bought my Hahn Stage II kit. I was looking for gauges and was wondering what the max reading (psi) of oil pressure gauge I should buy. I was thinking 100psi is enough, but is this the case? For anyone with an Eco, let me know what range of gauge I should get. Thanks!

im pretty sure 100 will suit you just fine. eco is somewhere between 40 and 80, i believe.

when its cold your guage will prolly get to about 100psi if you beat on it but id recommend letting it warm up to operating temperature before abusing your j with boost

I have a oil pressure gauge (mechanicle) tapped off my head on my ecotec and its a standard autometer one..im not sure what the max PSI on it reads but when my car is cold it reads 65 psi oil pressure and after a hour of driving it gets as low as 15 psi, So a 100 psi oil pressure guage should be fine for you.

100 PSI gauge. if you have cold winters and your car sits for a while you'll see nearly 100PSI on fire up. Get a 100PSI fuel pressure gauge too.


Shoot me an IM and I can help you out with getting and installing the gauges.
