What Gauges / Instruments Would You Recommend?

[RB240Dav]

I currently have a bone stock rb26dett in my S13. Prodject finished at start of winter here in November. I will be running a Power FC and the only functional gauge I have is the Volt meter.

So I need the whole gammet,

Water Temp

Oil Pressure (would you recommend electrical or mechanical)

Exhaust Temp,

A/F mixture

Fuel Pressure (because I'm using a Walbro fp)

Boost Gauge

I'm not looking for pretty, just reliably functional, at a reasonable cost. I would rather not spend $100US / gauge. Who should I be looking at.

Some side questions,

Can I derive exhaust temp from my oem O2 sensors. If not, what's best avenue?

Can I rely on OEM O2 sensors for accurate A/F when I'm not going for a really aggressive tune? ( I realize that I'm not getting real-time data with oem )

Are there other gauges I should get, or consider acquiring in the future.

Maybe these?
