Ok i got a Greddy Turbo Timer and a Boost gauge, what gauge is next most important to get?

 

Well if you are going to mod your car .. change a/f ratio's, bolt ons - get a Exhaust temperature gauge. It's a nice precise way to tell if your motor is running rich or lean. You can search for a "Pryometer Gauage" and you'll find one

well i got the Megan Racing 3" Turboback exhaust and a Intake. So what now?

 

Egt

 

whats EGT i forget?

 

Personally I went with a Wide Band O2 gauge. Granted, it's alot more expensive but it's a dead-on measure of whether your car is running rich or lean.

 

ok so a boost gauge and a air/fuel ratio gauge? or Boost gauge and something else?

 

My suggestion would be EGT, then oil pressure, and fuel pressure.

A/F gauge although a good safety net won't tell you much more than an EGT gauge since a non-wide band O2 sensor isn't very accurate. If your willing to spend the money, wideband O2 will give you a pretty accurate reading of A/F and is a good tuning tool.

 

narrow bands are only good for civics and christmas trees.

Get an oil temp gauge.

The egt will tell you if you are running rich / lean.

But since you are on stock programming, I'd say get oil temp. That will tell you when you can beat on your car, since the coolant warms way before the oil does. While you don't even really need a gauge, if you really want one, get one that you can actually use.

 

Correct me if I'm wrong. On EGT gauge if temp is higher it means I'm running lean, if temp is lower it means I'm running rich, or the other way around ?????

 

It could go both ways in extreme since unburned gas would ignite in the exaust system. It's a tool to tell you when you're about to melt your engine.

 

If you have the EGT probe in one of the runners, maybe 2-3 inches from the head, at what temperature are things starting to get dangerous? Does it make any difference that I have forged pistons?

 

Greddy EGT or Wide Band 02 w/ Air/Fuel guage.
