EGT gauge probe location

Hi guys
I want to fit some gauges to my car.
First question is: where is the best place to put EGT probe? dump pipe or manifold?

How do you drill and tap a 1/8NPT thread?

I have a high mount manifold with the provision for an external wastegate. Do you reckon I could install it in the blanking plate thats on there?

Also, is this the line you install the boost controller and boost guage tee on? Do you put the tee before or after the boost controller in the line?

Where do you usually run your PCV breather on top of the rocker cover?

Cheers

Post or pre turbo is fine. Its only a gauge for your reference.

with a drill and a tap and die set. Lol. Sorry had to be said.

sure why not? Looks easy enough there.

Goes in the air intake between the air box and turbo...

Answers in bold....

Go for a welded socket instead of a drilled and tapped hole in the dump pipe. There is not enough wall thickness to keep the thread from getting loose as it heats up - I know because I tried it and it failed - now have 1/4" NPT sockets, with reducing bush to 1/8"NPT in both headers for my EGT's and happy days. It cost me $50 for both sockets to be welded in at a local exhaust place and I supplied the mild steel sockets. You can buy the sockets on ebay. Check the size of the connection though as some pyro's have 1/8" on the probe and then have a special seating socket with male and female threads, hence why I have the 1/4" welded instead of going straight to 1/8"

Thanks guys.
@PeeBee, I'm just a bit worried about the taper thread on the egt probe. Will the tap cut it alright?

Usually gets dumped back into your intake. Put a catch can on it instead.

Mate, I'm intrigued by your intake setup. Any chance of a full photo of it???

Tapered threads are only tapered on the male, the female thread is parallel so no worries with tapping a thread... but... on the dump you are better off welding on an adapter as prev posted.

Best place is for the probe is the manifold, putting it post turbo means you are "guessing" the delta T lost thru the Turbo.
Different turbo setups/manifolds/positions will have different losses
Depends how close to the edge you want to run the engine.

As @ET says above. There is simply no meat in the dump pipe as its sheet metal. If going into the manifold watch out for swarf getting inside the engine. This goes for the drilling operation as well. If you go with the welded socket you only have to worry about the drill hole.

@Hodge it's just a temporary setup until I get a patroldocta airbox.😁

Yeah I will probly go pre turbo. Cause I have that blanking plate it makes it pretty easy.

Well it looks like my manifold will be coming off now, I am now practically taking half the engine appart lol

Nothing has happened I am putting in a new turbo and pump and I want to take my cooling system apart to check it out and I want to put my EGT prob post turbo so I want to take the manifold off to drill and weld I do not want to take any chances of swarf getting in and I am pluming up my new fmic and also most likely redoing the intake grrrr lol

Hey guys
Now I'm around to turning the fuel up on my fuel pump. I have the standard 10mm. How do you put more fuel in?

You don't I had the same problem with my standard 10 mm pump with out a compansater you will get the attention from the cops with all the black soot coming out the back when you put your foot down and it is bad for the longevity of your motor that is if you want to do it right, I replaced my pump to do it the right way over fueling is not good to get power
