Update from wrenching past few weeks.
New clutch, refreshed all vacuum lines and high pressure rubber fuel hoses, 8:1 rrfpr Vortech unit regulator, re-installed intercooler tubing to fit better, DIY recirculation BOV hose to intake tube, custom radiator mounts bottom and top, refresh engine harness and plugs, regapped NGK spark plugs, timing belt and pulleys, new head gaskets,, torqued head studs to wrx turbo spec, and new water pump.
Next will be to finish exhaust piping from DP to midpipe. Bought new TD04 turbo core to refresh that too. This setup will be comparable to a stock wrx but much lighter. Wastegate 10psi max.
