Standard Boost Guage

[TSTG33R]

Hey ppls,

I just had an fmic fitted, as well as a new POD filter and the boost upped on my R33. I now have a switch inside my car which means I can switch between two boost settings, the first and most often used is round 6-7psi, the second setting is at around 11-12psi I believe...

I am having a problem with the standard boost guage in the car, when I have it on the regular 6-7psi setting, when I come onto boost it shoots up to '0' and never gets any higher, although when I switch it to the higher bost setting, of which I can feel when driving that there is actually more boost, the guage works as normal, well, at least how it did before I had the boost upped therefore telling me I'm getting as much boost as I upped the boost...Umm..I guess that sounds pretty confusing!!

I am assuming this is a problem with the connection to the guage but am unsure, anyone else had this problem???

Also, what psi does the standard guage go up to?

Thanks alot,

Paul Paul

you realy need to get an after market boost gauage as thefactory ones can be unreliable

yeah, thought that may be a problem...damn

yes, factory guages are shit. Mine dosnt work, im running 12psi and the factory guage only goes up to 7psi, but the needle rarely goes this high!! so hook up an aftermarket guage. realy easy to do, just plugs onto back of the manifold to get vacuum/pressure readings.

The factory one is not in PSI its in mm/Hg or cm/Hg. Whats that? Its mercury, the 7 mm/Hg = ~13.7psi. As its been said many times the stock gauge is reasonably inaccurate its hard to read, best to buy an aftermarket. If you have a few hundred to spend (300-400) get a greddy/hks/apexi. If you dont get an aussie one, spitfire or something. The jap ones are more accurate in my opinion, but *anything* is better than the stock one in the car. I got my HKS one 2nd hand from japanese motorsport for $160 + P&H and works a treat.
