Hey guys,

Sorry to create a thread about this, Ive tried searching but I cant find what I am looking for :S..

Just wanted to know how the stock boost gauge works? what does it read in? as I am looking to put in my Turbotech boost controller in, I want to set it to 10psi.

Cheers

It reads in mmHG (x100)

1 PSI = 51.7 mmHg

1 bar = 750 mmHg

So..... '7' on the stock guage = 700 mmHG which = 0.93 Bar or 13.5 PSI

10 psi would be about a 5 on the stock gauge. Its pretty hard to pinpoint & guessing is not the sort of thing so you want to do with boost pressure so you need to get another boost gauge. :P

before i ran more then stock boost with an aftermarket boost controller, i installed an aftermarket boost gauge which reads in PSI, cant go wrong mate

if you dont want to do that, the above post is correct

Get an aftermarket one, or do it on a dyno, simple as that.

The stock gauges are generally too inaccurate to be reliable.

Do yourself a favour, and dont trust it or you could find you blow the turbo.

    • First time visitor and currently getting ready to start work on my HK Premier.  Its all stock, 186 with 3 on the tree.  The only mod i have right now is extractors.  I am hoping to get some guidance on slightly modifying the engine to bring a little more power. Just going for a nice, comfortable cruiser.  The car is very straight, however i have been out of the country for 20 years and its been gathering dust at a family farm.  Will be doing quite a bit of body work to cut out some small rust areas (frnt quarter panels and a few other small bits) and fix up the paint.  Will be redoing the interior (its currently black and the seats are in real need of recovering and respringing the driver side (its front bench seat).  The dash needs a little TLC, but no real damage.  As my heater has degraded I am considering fitting something after-market that will be both heater/AC (recommendations here are always welcome). Wanting something discrete that will allow me to use the same controls and not be obvious once inside the car.   For the engine, i have been told i could consider upgrading my cam (imagine i would need a new head as well) and putting a new carby (currently the original stromberg).  However not sure what is going to be the best route.  Would certainly welcome any comments/suggestions.  As  a final step I am looking at changing the wheels. Current hubcaps are in dire need of refurbishment or replacement (imagine its a bit like hens teeth).  Thinking of some clean/classic looking mags (7-inch should be more than enough - not going for a large change in look).  Welcome any comments/advice and of course any questions. 
    • I got the ARC M079 due to the space constraint.  Been running mint for the last 3 years.  Plazmaman also seems like a really solid choice but not used myself.    Hunt around for a better price but this is what I have - https://www.rhdjapan.com/arc-brazing-intercooler-smic-m079-bnr32.html
    • Wanted to follow up on this. Did you end up getting the M073? Still deciding on what to get between nismo m073-79 and plazaman.
