How long should it take to connect egt, boost & oil temp gauges?

why cant you do it yourself ??

I am not a Landcruiser owner but I did these and others on
my GMC Sierra.

I do not know if you have any ready to use ports, that might help.

EGT pre turbo: I would not trust any mechanic here to do that right.
With no port you have to drill into the exhaust manifold or into the
down pipe. Both will leave metal pieces in the exhaust, which may/will
damage the turbo. I removed the exhaust manifold and drilled a port
with a 1/2 inch thread for the probe and reinstalled after throrough cleaning
even though I pushed a towel into the manifold. If one does it right it will
take 1-2 hours depending how warm the workshop is :)..
Post turbo is a different story .. easy ..

Same applies to boost but usually it is easier to remove the intake. That took
me 1/2 an hour with mine.

I did not need an extra tranny oil temp because it is standard in mine. A Landcruiser expert has to answer that.

good luck

Just put the EGT in post turbo and add on 200deg.

Pull off the plastic guard on rhand side and drill a hole in exhaust pipe. DO NOT CUT THE WIRE BETWEEN PROBE AND GAUGE

The oil temp gauge I put in the cooler pipe behind the radiator. Can be done in the elbow coming out of the box but harder to do depending on the make of probe. Its the lower pipe that goes into R/H side of radiator. I used a t piece with barbs and tapped the bit for the probe so it screwed inside it.

Havent got boost just use the right foot

I drilled a hole through the firewall where there is an 8 shaped hole inboard from the brake unit

Look in my profile for the pics.

The tranny temp hardly ever gets over 75deg C anyway except once on a long hill and it got up to 90 which is still OK. An afternoons work i you do it that way several hundred $ to pay someone. Email me for opics if you want. WHere are u Im in Coffs atm
