Try an 80 series master cylinder first. I have a spare if you want to do some testing.
Thanks, I've already upgraded to the 80 series master cylinder when I switched out the rear axle. I don't actually know if I need bigger brakes, I'm just assuming.
I bet some tundra rotors and calipers will alleviate my worries :)
 
Drove it for the first time since the compound install. I'm very pleased with the acceleration and power, but I'm still stuck with the high EGT issues. This is a preliminary test run, and I didn't drive it hard because we still haven't installed the studs. I had a guy hold the camera while I took it to the field to try it out. Not the best video, but good enough for government work.

On the way back I blew out a boot, it sounded like a tire was punctured. Right now I'm thinking of advancing the timing, keeping stock injectors but putting in better delivery valves for the pump. This will be a long trial and error process.

The center-right gauge is boost, it hits 30psi no issues, the center-left is the PYRO, it can go to 1400 degree is a second or two.





I had better shots and videos I could have taken but was too busy playing to think about it.

I was expecting the turbo whine/whistle to be much louder. On a better note, it's not smoking as much as I thought it would be.
 
Forgot to add these. The short shifter goes in this week, but might take it back out if i don't like the feel of it.

So, it's a bit too early to judge since I still don't have my truck, but I suspect that I'm geared too high to effectively use my engine/tranny setup. I suspect that the EGT issue will keep haunting me in 5th gear. I'm thinking adding these transfer case gears instead of regearing the axles. They give a 4:1 low range ratio and a 10% underdrive, which is what I'm really leaning towards.

1980-1990 60/62 Series Land Cruiser 4:1 Transfer Case Gear Set (TOY-LC-38-4.1)

Anyone have any experience with them or know where to find them cheaper?
Edit
Might be better off with the 3:1 gears that give me 7% underdrive

I have Marks 3:1 and 8% underdrive in my splitcase. Other than the loud gear whine I love them.
 
I don't think the noise will be a detering factor. Everything else is so loud.

Did you have to grind the t case top make them fit?

What's your rpm when cruising at 70mph?

I did have to grind the case. At 70 I am at 2100 rpm I believe. The gear whine is loader than the engine and I may have other issues causing it as well. It was loud before the rebuild and gears and could even be the trans. If I go through a tunnel it's almost unbearable with the windows down.
I notice higher EGTs on hills if I run them in 5th gear at 65-70. They will be lower if I downshift to 4th and stay at 65 or run at 75+ in 5th. The higher the RPM the easier the engine is working to move the truck.
 
So you planned on doing a head gasket anyways. Are you doing any head work to it while it's off?
 
Yes, i figured might as well do a head gasket. Going to deck the head and reinstall it with studs.
Then it's just playing with the pump and timing until i find that happy medium without melting anything.
 
How heavy was that head? Did you muscle it off yourself?

No, this is beyond my skill set. It's at a buddy's shop. He's doing the actual work. I occasionally show up to micro manage, take pics and pretend i know what I'm talking about.

I “helped” do my first head gasket last week on our forklift at work. The Toyota 4Y alluminum head was so light you could hold with one hand.
 
I've taken my head off a couple of times, only the weight lifter with a young back would be able to muscle it off without hurting themselves. I've found that hooking it up to a engine hoist is the easiest, especially when putting it back on the block. You can go slow and give yourself plenty of time to align things going down. Studs make it easy to get it on right.
