69 Camaro single turbo I'm working on.
393ci LS1
ported factory heads
forged rotating assembly
GT4294R turbo
Stainless Works headers
T56 with RPS twin disk
26x12x3" intercooler core
Anyone have insight into what the best way to tie in for turbo water lines would be? I was going to use the heater core for the upper line and something in the block for the lower one. Does anyone sell a block drain plug with a fitting on it?
Also, thoughts on pluming in a cyclone separartor. Pull from the top end and return to the turbo drain with a check valve?






2.5 inch Y into T4 flange





4 inch downpipe

i dont have much input on the water lines, other than i dont really think water cooling is necessary.

It can, but not on that size engine. If you keep the rpm down to 6500 max it will need 85 to 90 lbs of airflow at 14psi.
Now go to the compressor map and plot 14psi and 90 lbs and see how far off the map it is......killer build if you keep the boost down and enjoy driving it...for big power the turbo will choke as the compressor is too small for that killer engine...
