Ok, you hahn turbo people. I have this kit and am in the middle of installing it and i was wondering which 3 gauges are the most important to get. so if u guys can list me the 3 gauges i should get that would be awesome. and also, are you guys using the factory exhaust manifold gasket when installing the hahn manifold? thanks again

Boost, Wideband 02, and Oil Pressure
For the Oil Pressure gauge, I think you will need an adapter to tap into the ecotec block.
The factory manifold should do fine.
ok if you have a hahn kit a fuel pressure gauge that is in the car is key to knowing your rate of gain but those three listed above are also important. Wideband is the most important no matter what. Boost would be the next important. Oil psi is good but not necessary. 3 gauges is not enough if you ask me. But i like to know everything. Just opinion i guess.

I would think the oil pressure is more important than the fuel pressure. The turbo relies on oil to keep it moving, so if you have low oil pressure, your turbo suffers.
The wideband gauge would show you running lean if there was a fuel issue.
That's my logic at least.
i agree. so fuel pressure is more important then oil pressure?

As far as gauges go, I think Oil Pressure>Fuel Pressure.
For the car, both are imperative.
oil pressure is present as long as your oil light is not on. If you have extremely low oil pressure oil light will come on. At idle when the car was warm my oil psi was 13-20psi. Your basing your tuning on fuel pressure with the hahn kit i see it as being important to the particular setup. Yes wideband will show if you have fuel issues but the car already has provision for monitoring oil pressure but does it monitor fuel pressure? or does it monitor afr accurately? Its like putting a water temp gauge on the pillar which makes me laugh everytime although probably a little faster reaction and maybe a bit more accurate definately not necessary. Hes asking for the 3 most important to his setup. thats my opinion take it as you will not saying im correct i dont think there is a correct answer like i said matter of opinion.
