Speaking of gauges, has anyone ever hacked the guages on the stock display? Like the mpg one or battery V one to show something else like boost pressure?

I have had this exact same thought. I mean, the MPG gage is about useless. I have not read or heard about anyone who has done it...

I think it'd be pretty difficult.

It's not boost pressure, but I'm sure you can swap out the MPG gauge with the Oil pressure gauge in the Altezza. But making it work is another problem. The oil pressure sensor on the IS just provides a signal for the warning light, so it won't do any good hooking it up to the gauge. Maybe there's a oil pressure sender (gauge type) from another Toyota car that can fit on the 2jz?

You would have to replace the entire MPH piece on the console. If you did that, you would have to use the center piece from the JDM version and wire it up to make the new gauges work.

Really? I could have sworn that I saw on the service manual that those small gauges were able to detach from the MPH piece. Guess I'll check it again. So when you opened up the instrument panel to change the lights, you saw that all the gauges were just one piece? Well if that was the case, I wouldn't do it because I don't like to read in KPH hehe...

haven't had the time yet, i thought about it as soon as i got the car, i even did a pretty good photoshop about a year ago of how it would look and put it up on tbko's site, but haven't had the time to actually figure out the circuit

I know a boost guage is always one, but what are the other two usually and why?

What is the purpose of knowing you EGT and fuel pressure--to make sure everything is running ok?

egt is so you can basiaclly tell if you're running lean. fuel pressure is so you can tell if you're GOING to run too lean or rich...um...sorta... :p
