Get SW gauges at 42 draft designs. Good price, prompt delivery, great service. Ask them to pack the gauge in a lot of foam or it might arrive with the needle high or low 1-2 psi.

I recommend getting the 30-0-40 gauge because you may want to go over 25 psi some day on race gas, alky, or a bigger turbo.

Thanks for the link! I'll be placing my order either today or tomorrow. I'm going to stick with the 25 psi gauge because I plan on staying with the stock turbo for a long time and if I do upgrade it will be a 50trim @ about 24psi so I don't need the 40psi gauge.

EDIT: I'm a little girl when it comes to running high boost levels. Plus since I refuse to run water or meth injection running anything over 25 psi on California's famous 91 octane is just not going to happen.

 

Gotcha I didnt know you had already verified this. Yes, the SW gauges are also 52mm.

 

my autometer boost gauge worked for a month or so but now it sits at 10 in vacuum when the car is off and will show boost as being anywhere from 11-16 PSI

going to have to buy something to replace it soon

 

the only way you'll ever get an accurate boost reading is using a map sensor to monitor your boost. the only way you can confirm that boost is accurate is to compare with such a sensor.

 

Even in CA you can always put in some unleaded race gas: Sunoco GT 104, 76 100, or VP Racing 101 or 109 and turn up your stock turbo (or 50 trim) boost to 28 psi--or at least 25 psi. If you do this, at 25 psi you'll be at the 25 psi gauge max reading and you won't know if it even goes over 1 psi. You need at least a 30 psi gauge on the Evo unless you never run anything but 91, and why would you with so many alternatives avaliable? You make a lot more power on a 91 flash at 26 psi vs. 22. The SW 30-0-40 gauge costs the same as the 25 psi gauge, so why get the 25 psi gauge?

 

I know so many ppl, including myself... who haave used Autometer gauges and have has 0 problems... This is actually a suprise to me that some ppl are having problems.

 

The Defi mechanical has been discontinued for performance review. You might find some vendors stills selling them. I found that out today from the actual manufacturer because I had IAperformance tryingto order me one today for my Stealth.
