Just bought a set of boost and oil pressure EVO digital gauges. Currently I have 52mm Omori boost and Greddy oil pressure gauges on my car (they are for sale).
Just finished doing wiring today. I noticed that wiring supplied with the gauge is way too short, so it's necessary to acquire extra set of wiring. Also, vacuum hose supplied is cheap and easy to damage. Spend a few extra bucks and get either rubber or silicone hose (4mm ID).
I haven't had a chance to install the gauge on the car due to the snow today. Will post some more pictures.
Throw away cheap vacuum hose. I used left over vacuum hose from Omori boost gauge.
