ordered adapter from geno's garage for turbo, fuel pressure no problem installing oh, does it matter which brass fitting on top of filter to install this.

egt??? should if be before or after turbo, was not sure about drilling with shavings possibly getting in turbo if i put it before. where is the best place to install probe
fuel pressure min. 5psi turbo range ? max. egt ?
thanks in advance

before the turbo, in the rear port of the exhaust manifold, about 1" to 3/4" from the turbo flange.

The question of probe location has been debated endlessly.

If you're going to tweak your truck, then install it before the turbo and avoid leaving shavings in the manifold. You can do this by taking off the turbo, coating the bit in grease and being careful, using a little magnet and pretending you're lucky, or by drilling the hole with the engine running.

Use anti-seize on the probe before you install it.

And it's probably a good idea to leave a service loop.

yes, the turbo needs to come off first. then shove a rag in ton the manifold as far as you can. drill your hole, vacum out the shavings, pull tha rag, re-vacum the open manifold and then reinstall thr turbo.

You can do this job without removing your turbo.
Drill the hole, use a small magnet to remove the shavings from the manifold.
Grease the tap, tap the hole and use the magnet until no more material can be picked up. In stall your pyro and your done.
I have done 4 trucks like this. 2 of my own.
I never had a problem with them. Just make sure your thorough.

thanks guys, gonna give it a shot today

Forget the grease, magnets, etc. You'd think many folks are under the false assumption that drilling chips are going into the intake portion of the turbo. Needless paranoia, any chips will blow right out the exhaust the first time the engine is started. I've tapped in dozens of pre-turbo probes and do absolutely nothing special and have had zero problems.

Just to be on the safe side I dropped the turbo a few inches and taped over it.. I was suprised by the amount of shavings that were on the tape..

Also pull the plastic inner fender well... it gives you an almost straiget shot to the manifold and you can rest on the tire while you do the work..

He's got a 99 truck Gerry. Unless he's handy with a plasma cutter he's not going to pull the inner fender liner.

chiefallred

good with the plasma but a little extreme for the mod

could not get done today, will hit it after work monday, did get all the gauges mounted and wired, fuel pressure is operating. yea

do not fully understand the turbo though. found at geno's garage an adapter that i will have to order monday since they're closed today. is there really that much pressure at the intake. gauge has both 30 psi and vacum.

J BODY

Sounds like you have a gauge for a gasser with a turbo if it has vac/and psi. Diesel has no vac in the intake.

oops... sorry about that ... Didn't look at his signature... My BAD

He's right--you don't need a boost/pressure gauge; just a simple 30 psi boost gauge. The gauge you got will work, but you won't be seeing the needle dip into the vacuum range. The max boost you should see on a stock '99 according to the general engine data on dodgeram.org is 17.7-18.2 psi +/- 1.5 psi (or more simply put, 16.2-19.7 psi), so yeah, there's some amount of pressure there.
