VVT head + 94 block + real OPG + turbo oil line

VVT head + 94 block + real OPG + turbo oil line
1) Will the oil source line for the VVT oil control valve bolt to the the 94 block no problem.
2) My turbo oil source will be on the exhaust side of the block (it's a 94 block after all). I'm thinking of mounting the real Oil Pressure Gauge sender onto the turbo oil line at the turbo end. What fittings will I need?
3) Are there still 8.8:1 factory pistons available from Mazda?

not sure if the boss for the hardline is there on the earlier cars.
94 stock pistons are 8.8 and slightly dished. later cars are higher.
I ran the oil feed/gauge from the original sender location. lots of stuff hanging off there, but so what.

94-97 blocks should have the oil port on the hotside. Beware hanging lots of stuff off one oil fitting on the side of the block. Vibration tends to kills those in track cars. First thing we do is fit a distribution block on the firewall. At the very least, make sure the thingy on the block is steel, not brass.

Ill probably be doing this on my new motor with:
Oil feed
Real oil pressure sender
Aftermarket oil pressure sender
Oil temp sender
The only thing i am a bit worried about would be pressure if i pulled it from both sides of my early 1.8 block. I plan to pull it all from the pressure sender side but have been toying with the idea of pulling just the oil feed from the exhaust side. Thoughts anyone?

Your concern, if I read correctly, relates to taking oil for the turbo from the fitting near the flywheel on the hot side of the block, and measuring pressure & temperature at the stock sensor location on the cold side.
This is (almost) exactly how it was designed to operate originally in the 323GTX, and how most of us with early blocks are running.
Or an I being obtuse?
The only thing that would concern me is temp sensing on the coldside. Reason is that you need a continuous flow of oil across the temp sensor, and you're not going to get that if you're measuring at the end of a dead line.
Perhaps a sandwich plate between the oil filter and cooler would be best for this? You could also place your aftermarket sensor here, though of course it will read slightly high as this location places it before the filter.

I've oft wondered about this myself. In a situation where an oil cooler is present (such as the OE water/air unit on the '94+) is it better to take the oil's temp before or after the cooler?
Part of me wants to say take it before, as this is as close as you can get to measuring whatever the highest temp the oil achieved was, and thus how close it is to the breakdown point.
Another part of me wants to measure it after, for reasons that I can't quite quantify.

Does anyone have a decent diagram for oil flow through the motor? I pull oil temps off the pressure port under the IM and they are always super low - I haven't done any further testing to determine whether this is my stupidly-large oil cooler, or whether I'm just measuring oil that's come straight out of the cooler.
