Turbo Gremlins
« on: October 22, 2006, 06:48:56 AM »
Hey guys, got the turbo in and it runs real strong. I've been chasing a few small problems though, mostly fluid (oil leaks) which I now seem to have taken care of, and some minor driveability issues. At anything above idle its good, mostly seems normal till it comes on boost at about 2300 rpm then you can definitly feel the power start to build. From there to redline it pulls real strong with cool " wooshing" sound, sort of like a giant vacume on steriods. I'm only pulling about 5-6 lbs boost at max, but it adds a substantial amount of power, even down low in the rev range. My problem is at idle, which is a bit low about 600 rpms. In drive or any gear
(It's an auto) is seems ok or close, but once warmed up, in park or neutral its low enough to set off the oil lite. At this point that seems to be the only issue. There is no pinging, surging, overheating or any real issues other than the low idle. I'm still running 87 octane( still had a half a tank left) have not done anything to the timing ( still stock) added new injectors 20lb 210cc, but everything else is the same as before the turbo install with one exception. I teed the oil feed for my turbo off my oil  pressure sending unit, which already had a T  fitting on it for a pressure guage. Since the Turbo feed comes before the pressure guage feed, it now reads lower pressure, I think because of the constant flow thru to the turbo. Have to find another place to take pressure readings from. The port next to the oil sending unit looks good, but the plug is really stuck in there.  Any suggestions on the Idle issue would be greatly appreciated, as well as another possible place for oil pressure guage take off.   Thanks Much.

Maybe switch to an external oil pump and an extra cooler for the turbo?

 ???    Turbo's getting plenty of oil, thats not the problem. And oil temps are ok as well. It's the low idle I want to correct. Any suggestions? WILD? Anyone? What happened to all you turbo guys anyway? especially you Wild, I sent you a email some time ago, no answer. ???
