I was gone when they plumbed the coolant line into the block, I don't know how you manage that either but they said it was in some schematic...
I am doing fab , internal tranny and engine work only, the rest is being assembled by other people not apart or associated with my shop.
As for the dead cylinder, they were in the middle of diagnosing it when they lost all spark. I had to lock up the shop and kick everyone out at 3 am, and thats were they were at the time.

Gay.

Than if you are doing all of that you may as well do the same thing for the aftercooler and the intake manifold...
It can spiral out of control pretty quickly and it gets expensive, and unfortunately this time around wasn't part of the budget, id o like that style of testing though and have done lots of it for stuff I build for pikes peak and the baja 1000, unfortunately I don;t own all that test equipment YET, should before the end of the summer though
The housing really is the best place though, if you aren't running 2 per primary.

This has to do with manifold design as much as tuning, and gathering data for that. For tuning egt's as close to the cylinder or cylinder temp gages would be the way to go. This will still give a fairly accurate idea of what is happening at the cylinder as well as the balance across the setup.
On a side note, does anyone know how much pressure is in the clutch line?

Pressure sensors are a nice thing to have, but putting them where the gates vent from will be most representative. The turbine is supposed to change pressure and velocity of the gas. That is it's job. However, you only really NEED a pressure sensor if you have a shitty setup and are expecting poor efficiency. I don't think that's a concern here.
As for EGT's why not just 4 at the cyls like BDVT said. Do you want to measure what the engine is doing inside? Or do you want to measure how much danger the turbine wheel is in? Horses for courses. Most people want to know the former.
Nice work on turning the housing down. I turned a vband flange up from scratch to match the holset and got a correct clamp. They are common in the states. I had to order it in NZ. Still, only cost about 20us or less for a genuine correct one.
About those gates/flares, you are dreaming if you think that will affect boost control at all. Secondly, if it did, it would make it slightly worse than a straight pipe, not better. None of it matters much though, "rippers" are what it's all about anyway :-)

Ill bite on the pressure sensors in the housing (If it were mine id probably still have had done it in the manifold rioght were the merges join though- opinion)... From a R&D standpoint ok. Its Viable.
However I have to stick with my thought on the egt probes being in the turbine, or even one per merge collector...... The reason I asked was that youre going to have ALOT better idea the motor is doing with them closer to the port in each clylinder runner. Having them in the turbine is going to be nowhere near as acurate an indicatoror benneficial as it would be either.
THATS where the concern should lie

I am not the least concerned about his ideas, If it can work on those trucks, it will work on my civic

maybe i am being completely ignorant here, but when looking for the kind of power you are shooting for, wouldnt you want to tune each cylinder? without something weather egt or wideband on each runner you cant do that. i know the standard 250hp ls really couldnt benefit from tuning each cylinder, but im sure its a make or break part of a setup like yours.

Oh, by the way... I didnt know you were building a "baja truck". you
