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.
