Westach Combo Gauge

[ablakemore]

I want to buy and install the Combo Gauge (boost and EGT) in my 1996, 5 sp, but am confused in what size probe. Comes in 1/4 or 1/8 inch. Which is the correct one to use.

Any advice will be appreciated.

I went with the 1/8" NPT due to the fact that it is easier to tap the hole and besides why drill a big hole when you do not need to..... and I'm a machinist!

Makes sense to me.



Thanks Mike

Best reason to use 1/8 NPT is if you goof up you can do 1/4 NPT and a adapter!!!
