what gauges shall I get?

[Colin Wiltshire]

If things go to plan, I should have space for 6 gauges, currently I have Boost, voltage, oil temp and soon to be afr. That leaves 2 spaces, any suggestions?

[swinks]

Oil pressure and maybe fuel pressure.

[Colin Wiltshire]

Have an fpr in engine bay

[Nick Mann]

Oil pressure.

I would be looking at some kind of knock detection, assuming you are thinking of tuning in the future.

[Colin Wiltshire]

Tuning, most definitely. few evo knock censors on ebay

egt gauge better idea then

[Nick Mann]

Why would you go for egt over knock, Tomasz?

[swinks]

Simply, our engines can develop extremally high EGT without b**dy knock. I know of 2 modified vr4 and maybe 3rd (but can't be sure) melted itsef without warning knocks.
Anyway, if Colin is aiming for a big power then IMO it is MUST HAVE.
Engine knocks can be monitored from standalone ecu or good piggy back level, so gauge is not necessary.
