Cant find a place to pick up boost from in TD42?
G'Day All
I have been reading some really interesting threads on here relating to what i am going to do over the weekend but have a few questions that need clarifying.
I have a aftermarket dump pipe installed on my rig with the bolt that can be removed for the EGT guage install after the turbo. Should i use this to guage my EGT temps? or should i drill and tap a hole in the manifold for the sender?
Option one sounds easier to me as im thinking that if i drill and tap the manifold i would have to remove it so the shavings ect dont end up going through the system.
The guages i have are the alarm ones so maybe i can set my alarms off to start warning at lets say 450 instead of 500 deg to make up for the temp differance before and after the turbo?
What are your thoughts.

Yeah mate use the one in the dump pipe, it will be fine and well placed for Post Turbo temps. i have run a pre turbo and a post turbo and the pre turbo setup just did my head in, the temps spike allot more and are higher and you are always trying to guess the conversion on the fly and it'll just fry your brain.
When most on the internet quote EGTs they are talking about post temp readings so no point coming to the table with a heap of pre temp readings with very little to compare it too. Dont do it mate it will give ya the shyts!
The difference between pre and post turbo will be closer to 200 to 250 degrees mate!!! so you will see up into 750 or 800!!! How confident are you making the conversions on the fly when your towing a trailer through Central Aus pushing 750 degrees up a hill????
Put it in Post turbo and then you can compare to all and have a yard stick.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

I hope you can get that bolt out mate. Is it those Allen key ones?
Sometimes they seize up with the heat and cold and just don't come out.
Spray it with wd40 tonight mate and pray that it comes out this weekend.

Yep that will be the best spot mate. Ferret wrote in another thread the other day that you could drill a hole in it and install a tubeless tyre valve and strip the valve out and you have a thread. Simple and easy.

cheers Mudrunner, i read that one. Just not too sure about doing something like that and thinking welding a solid bit of tube coming off would be the best option. Im sure this fitting is steel and not alloy so should be a simple job.

ended up making a custom little fitting and welding a nozzle to it. Seems to be doing the job and looks neat. I have done a wright up in my build thread incase somone goes to install a boost guage in a TD42 with a front mount intercooler here
