Finally finished the turbo on my N/A!!! (Some info...)
FINALLY!
The turbo is finally installed and running on my street ported, high compression N/A.
WOW.
That's all I can say about the power. As soon as the turbo spools up at around 3300 rpms the rush of power is amazing.
My first quick drive, I still had 87 in the tank, my S-AFC was still tuned way lean for N/A power, and my timing was still bumped up! (oops..) I rolled on the gas for a quick second, saw the gauge spike up to 9-10 psi, and heard a nasty popcorn-y / rattle, sounded weird, like metal on metal, oh ya, detonation!!! I have since richened it up like crazy over 3500 rpms(only -10 with 550cc secondaries, so theoretically at +10), and dumped some 91 in the tank, the detonation's gone.
Funny, it sounded more like it was coming from the turbo, and not in the engine.
Anyways, I still have a few glitches to sort out, my oil feed is leaking where I tapped into the oil cooler, and it seems there is a little bit of white smoke out the back- smells like gas! Funny. Hope the oil seals in the turbo aren't gone.
The BOV isn't installed yet, so I'm not laying on it.. don't want to damage the turbo!
The intercooler piping looks sweet! I'll get some pics of the whole setup when I can, but if anyone has any questions, let me know.
S4 turbo/manifold. Removed twin scroll. Ported wastegate.
2 1/2 inch manifold spacer
stock DP with no cat, had to reshape the pipe a bit.
2 TII intercooler cores welded together, and mounted in front of the radiator (rad moved back about 4 inches)
2" IC piping.
550cc secondies, S-AFC
TII fuel pump
Oil feed tapped into side of the oil cooler
oil return bolted to the side of the oil pan
Coolant taken from the heater hose.
Had to cut a small chunk out of the pass side frame rail to clear the WG actuator, but not much.
F'in FAST!!!
