Boost gauge and EGT install

[Diorama]

I'm also looking at installing an intercooler. Any ideas on the best brand to go for and also whether to go top mount, front mount, air cooled, water cooled etc. This will probably start a good discussion but I want to install the most suitable for towing. Remember I'm towing a 3500kg boat. I'm installing both EGT and boost gauges and will increase the boost and fuel a bit.

if your using it for towing lots then the front mount would be the way to go. Least amount of things involved and lighter. and is open to the most air flow.
As far as size goes the biggest you can fit . I wouldn't go with big(as in 3in) piping as it slows down boost response time.

The only problem that I can see with front mount is the space to put it. I already have a trans cooler with an aux fan in front of that for those slow hill climbs. So can you get all different sizes for front mount to suit.

I may have had a brain storm. The radiators in these landcruisers have an extra inlet and outlet pipe in them for the auto trans. They were never really that good for trans cooling when towing hence if heavy towing an aux trans cooler is normally fitted. When this was done to my cruiser the original pipes out of the radiator were blanked and the pipes from the trans were run to the new cooler. Were these extra pipes to the radiator from the trans designed for trans cooling or were they for getting the trans to an optimal operatging temperature. If they were for cooling is there any reason why these extra pipes couldn't be used for an inter cooler.

those extra pipes aare for the auto but a) they aare to small(only 10mm dia),B)they would heat the air up not cool i down.

If your engine fan is working properly you shouldn't need an aux fan as an electric fan will never flow as much as the engine driven one.my auto cooler is a stand alone system like yours and the one time it got close to hot was towing a 2ton digger up a big arse hill.(auto safari) got to 87deg at the top.
You can put the auto cooler under bonnet with a fan but isn't ideal.
Have been trying to convince me pa to do the same.have had a look at his truck.same as yours. if you put things as following they will fit. from engine to grill should go rad,air con,intercooler,trans cooler.
try and find a cooler between 50-65mm and it should fit ok.

I find the extra fan slows down the temp increase just enough to keep my trans temp at an acceptable level on those long slow hill climbs when these not much air flow through the grill. I never used to have it but once fitted the difference is noticeable. My trans gets to about 220degF. If it gets any hotter I pull over and select low range. I have the automatic centre diff lock disconnected when low range is selected. So have to engage that with the dash button. Once in low range the trans temp pulls back to about 180

my 80 had a single trans cooler fitted (it had a manual radiator for some reason) and the trans heated up under load.. i fitted a 2nd one and it never got "hot".... def do a front mount intercooler, and if you are after more low down boost get the guys at Alltech in Glenfeild to rebuild your CT26 with Garret internals to help it spool up faster

If its not cooling enough maybe you need to check your viscous fan cause they are known to need the oil in them replaced.
You should be able to hear it cut in. they are quite noisey.
Also how big is your trans cooler. Shouldn't be any smaller than 18 rows for what your doing.

Viscous fans working fine.
Engines not getting hot. Its just those long slow climbs in 2nd gear that heats up the trans. Its not getting overly hot as the trans temp light dosen't come on untill 300F and goes out again at 240F. I cooked a trans a while ago and I wasn't even towing and it cost $4500 to overhaul. It wasn't long after I got the cruiser so it was probably on the way out anyway. I'm just super cautious with it now and figured if I can keep it under 220F I'll be safe.

i'd be getting a bigger cooler then should be able to get rid of the fan

Its already got a 50 fin cooler. Its staying within the normal operating range but at the top end. Trans oil deteriorates with temp so hotter it gets the less time it will last. So the cooler I can keep it the better. I also get paranoid about it after spending $4500 on the trans. With boosting it up and increasing the fuel I should be able to keep it in 4th gear longer. It sits at about 180F when in 4th on the hills.
