HP, thanks for the response...If it isnt too much trouble for you to send those pics, that would be greatly appreciated...another questions though, what do you mean by tap them 'shallow"?...what about the boost gauge?...where is the best place for that...thanks alot

I have the pics at home..

I'll put them in my gallery tonight, or email them to you.. If I don't forget!

Tapping 'shallow' means to run the tap 'not quite' as deep as you would normally when 'pipe tapping' ..say... 1/4, 1/2 or greater thickness stock/material.. When you tap with a pipe tap, you generally only thread or cut 'about' half the way into, or down the tap.. Sometimes a smidge more.. And when you thread the pipe fitting in, it will start to tighten/pinch at about half way down the fitting..This is good.. If you cut/thread down half way on a thin piece of material, the 'area' that the threads bite onto is reduced, and can cause the fitting to go too deep, and might not tighten correctly, or bottom the fitting out against the hex end.. Not what you want..
Tap shallow to begin with, test fit, and if needed you can always go deeper..

The easiest place to hook up the boost line would be the MAP sensor line.. A quick 'T'' into the line..

You have to drill no mater what. I have boost and pre and post pyros. I tried to drill and tap inplace for the pre pyro. many people have had luck but with the shavings and I was not happy with my tap job I ended up dropping the manafold and welding on a bushing/sleave that I had on standby.

The Post I put in a new SS exhaust so I drilled and tapped in before istallation and put a locking nut on both sides.

I opted to tap my boost infront of the manafold to get the most accurate reading. Although I doubt that there is any significant deviation at that point from any other.

good luck!

Couldn't email you.. Feel free to email and I'll attach them, or there's 'some' pics in the gallery ..

HP, looks like you have plenty of toys...so on the egt probe, i shouldn't put the tap all the way through the manifold so that when i put in the probe it it tightens before it bottoms out the head...right?...that way when it starts to get tight it will be because it is threading through the untapped part of the manifold...sorry to be so stupid about this but i want to make sure i do it right...i dont feel like messing up my $40,000 truck!!!

What kit did you get to do it with...i have heard that some of the kits don't come with enough wire and tubing to do a complete install.

thanks a lot

 

Pipe thread is a 'tappered' thread.. So.. you only need to thread down the tap 'about' half way.. The starting threads/edge of the tap will cut threads all the way into the manifiold, but DO NOT thread the pipe tap all the way through the manifold/hole.. The deeper the tap goes, the larger the diameter the hole will be.. And, being that these manifolds are relitively thin , tap it 'less to begin' with, and then test fit the fitting.. If you don't tap enough...No big deal.. Just thread it back in and go 'slightly' deeper.. But if you 'over' tap, the fitting may not tighten enough, and also won't give you any extra threads should the fitting come loose ect. But, the most important thing, is to make sure you do a clean job, and don't leave any shavings/bits in the manifold.. Remember.. Start very small on the drill bits, and graduate up to eliminate any large pieces..

The gauge pictured is the ISSPRO R3607GR EV Pyrometer.. Almost an 'exact' match to the OEM gauges.. Backlit and all.. and you can get/order the thermocouple (probe kit) with 'either' a band (clamp on), or thread style fitting (pipe thread).. And what ever leadwire lenght you need.. Mine was 10 feet (R660-10), but could of used less.. With the probe in this location, it's an easy reach through the firewall grommet to the gauge/amp. The kits when ordered, should have everything needed to complete the installs, including the boost gauge.. Some fittings may be required for hook up, depending on where you tie in for boost..

The EGT kit I ordered, had a band clamp as part of the gauge kit, but could be 'upgraded' to the pipe thread style probe/fitting for a few bucks more..


Don't worry about asking questions.. It's part of what this site is about..
Should you need any help along the way, its just a post/email away, as many members have done the install/s..

I've drilled and tapped all mine with the motor running. The particles blow-out and don't go through the turbo. You can grease your bits also - particles stick to the bit.

Excellent idea never thought of that

 

Thanks For Info.
