    Re: How many of us have used studs from Northstar Performance ?

    The Northstar engine was born to RUN: But there is a difference between using an engine to its design limits and abuse.

    "performance" brake rotors and pads are a perfectly legitimate upgrade for someone who frequently drives the car to its potential. An SLS is the luxury cruiser side of the Seville series, so "performance brakes" is an oxymoron - EXCEPT for the Japanese/EURO W-rated SLS monsters. (We have a new SLS owner in Europe that regularly cruises his 2000 SLS at 120 mph for hours.)

    Because your U.S. SLS is speed limited to 112 mph and is not really set up for screaming in the back road twisties, the AC Delco service brakes are perfectly adequate for 99% of your braking needs.

    Re: 2002 Northstar WOT and performance brakes

    Abuse is abuse - i can punch you, its going to hurt a bit but you will get over it, if i punch you and punch you and dont stop, your heart could stop, same idea.

    though i dont think there has been one day where which ever car im driving didnt see WOT. though its not everywhere and every chance i get.

    Re: 2002 Northstar WOT, performance brakes, CORSA ?

    With a lift, normal shop tools and a good eyeball you can do it. As always, measure twice, cut once - and follow the instructions exactly. Most royal screw-ups on a CORSA install occur when the installer tries to wing it. For an amateur it takes 2 hours with proper tools. I would recommend the $75 cost to have a decent exhaust shop do it.

    Open this link and scroll down 2 pages past the STOP sign:
    http://www.corsaperformance.com/medi...ll/INS5011.pdf

    You must remove the after-cat O2 sensor and re-install it in the new resonator pipe - be careful.

    The system 'sound' has a low rumble at idle, is pretty quiet around town and on the highway but during a WOT run to redline it will wake the dead. There's not a baffle in it anywhere - it's all straight pipe with various sized holes/slots in the pipes inside the resonator and muffler cases.

    The system will NOT gain you any fuel mileage. There is a small power gain up in the RPM band at WOT - otherwise nothing under driving conditions either. Your SLS VIN Y engine is not set up to be a drag queen anyway, so the CORSA is for warm and fuzzy only.

    The system uses the original rubber isolation hangers. If, after install, it tends to walk to one side or the other due to slight muffler misalignment you can center the system in the muffler hanger rods and place small (fuel line size) band clamps on the hanger rods on either side of the rubber cookie - the system won't walk again.

    Find the thread in Seville titled "Vroom Vroom". It contains before and after dyno runs on a 2001 STS. 125 posts, last one was 10 February 14. http://www.cadillacforums.com/forums...orsa-dyno.html

    P/N 14150. About $1300 or so. Mine is now 7.5 years old and not a speck of rust. Find a dealer in www.corsaperformance.com

    Re: 2002 Northstar WOT, performance brakes, CORSA ?

    If you filled it "all the way" its overfilled. Please look at your surge tank for the FULL COLD legend and flat arrow molded into the tank top.

    Overfilled means the engine will now blow off coolant as necessary to maintain the required airspace over the coolant in the surge tank.

    Coolant level is checked and adjusted COLD, never warm or hot. Study the sticky posts just above this to find out why. You might also want to study the entire Cadillac Technical Archive way up ^^^ in the top black bar.

    Re: 2002 Northstar WOT, performance brakes, CORSA ?

    The coolant in the entire system - 3 gallons or so - expands and contracts a LOT during warmup - cooldown. If you replaced system parts a while ago it's possible that all the air is now purged from the system, coolant level in the surge tank dropped low enough to trip the level warning. You brought the level up to proper height - the sensor turned off the DIC warning.

    If you smell coolant at each under hood check, there's a slow leak/weep somewhere. Time to go to work with a good flashlight or drop light and look for wet/damp spots.

    Yea the problem is is that when it said it was low I would smell coolant but now that I filled it up it don't smell nd I look every day nd I c is oil no coolant
    The O ring is starting to brake on the oil pan but I don't have I think that wanted 1200 to fix it so just puting more oil in is cheaper now It is leaking to bad
