so i finily got the money to put some gages in the old girl and i got the autometer ultra light pyro and boost for starters. and i also ordered this for the install http://www.genosgarage.com/prodinfo....ber=KIT-NPTTAP , and i was hoping that somone on here as used this, or can tell me if it is the right size to drill the and tap the manifold.

the drill bit is 11/32, and the tap is 1/8 by 27 NPT

Any help would be great

 

That should do. I run the Ultra lite gauges in my ford and the pyro was 1/8". That was about 10 years ago but Im sure nothing has changed. Good luck.

one more question, wrer is the best place to put the boost fitting? In the IC tubing or is there a place on the head?

 

Theres actually a plug on the side of the head, remove the plug and run in the boost line....would be behind the bracket that holds all the linkages and stuff, you'll have to drill a hole in the bracket so the boost line can go through it, if you bend the boost line 90* to sneak it back behind the bracket, it may not work right.

This should show you where it is, you'll see it if you look on your truck, it'll just be a little plug with a 7/16 head.

 

hi

this is completely irrelevant to the thread but i remember in another post you said you are getting 23 mpg!, i have the same exact truck but 377,000 kilometers and different mods, i thought i was getting 15 mpg but my conversion from km to miles wrong im actually getting around 20, i was really happy to know that

anyways good luck with the install and id be curious to know what your putting out for boost psi, i have the lagmaster 21cm housing and you might have it too b/c your truck is a 92

thanks

Justin

 

wow that is a big help thanks i have seen that plug on the head but never pay any mind to it. thanks

and yes i still have the lagmonster for now and the 23 mpg is from living on an amry base and i am the only first gen on base. So i am easy to spot

 

If you have an intercooled motor, the plug should be right in plain veiw.

 

Save your self a future problem and get the copper line instead of the plastic line it comes with. I found it easier to work with and it won't get brittle and crack.

 

Thank i will look in to that. Home Depot should have that size and the fitting for all the coolers in the barstow area

 

I tried Home Depot, they had the fittings and not the line. That might just be the one near me, they never seem to have what I need. I got mine from Advanced Auto. It was only 6' long just enough to go to gauge on the pillar. The line comes as a kit that has the fittings in it. I think its meant for oil gauges. It was only around $10.

 

Yea i am in "socal" in the barstow area and they run a lot of swamp coolers and not a/c for houses so they have a good amount fo the copper tube, and the auto parts stores suck here
