LQ4 into a 3rd Gen/1972 Nova by frojoe

Here's the good 'ol exhaust post-welding...

And installed an intake manifold, manifold... connects to the L76 intake via a single 1/2" line on the back of the manifold, and has connections for the FPR, my Speedhut boost gauge sensor, then an extra 1/8" NPT port just in case I want to add anything later on...

Here's the solution I thought up for my oil cooler lines situaton, it's a junction block that serves a handful of purposes:

1) serves as an anchor point to force a bend in the oil cooler lines under the accessory drive, for flex during engine movement
2) allows me to machine a shallow angle for the turbo oil feed lines (30 degrees, on cold/return side) instead of buying and plumbing 45deg fititngs, or worst possible using 90deg tees
3) allows a location to mount the Speedhut oil temp gauge sender

The two angled surfaces are drilled for the turbo feed lines...

On the other side is a port I'll weld a threaded block to, for the oil temp gauge sender...

These are the two turbo oil feed pickup holes...

Trimmed the hex's off of AN weld bungs for more weld clearance, just tacked in place to mockup and test the theory...

This shows the mounting location, the passenger turbo feed line connected, and the heat-shielded oil cooler lines snaking under the P/S pulley...

I'll add two more -10AN weld bungs to the front to which attach the oil cooler lines...

Here are the cooler lines running under the accessory drive, and back to the pan. It's tight under there, but the lines are DEI heat shielded and ziptied in strategic places to prevent rubbing on the block or the subframe..
