1987 Buick Grand National
I bought this beautiful Grand National on eBay Motors in January 2010 from an owner in Florida. I've had extensive work done on improving performance and really having it idle and run smoothly and get decent gas mileage. I haven't raced or had this at the strip. I had long conversations with the owner before I bought it and most everything he related was true and accurate. The core of our discussions accepted the fact that this is a 1980's vehicle a G-body that shake-rattle-and rolls. I've done some things to tighten it up particularly in the front end but it still makes some racket over very harsh surfaces. That's just the way it is. Body has approx. 139K and the engine about 39K It came with a beautiful repaint but since I have driven it 39488 miles there is some road rash on the front air dam grill and front painted surfaces but no dents cracks hazing or scratches. It could use a professional buffing using a reciprocating buffer and compound. There is no rust of any kind and I don't drive it in the rain or snow so from November through mid-May it sits in the garage and I drive my battered Toyota Echo a coffin on wheels. Fit and finish overall is pretty good for a G-body no wide or unusual gaps. Windshield is clean with no scratches or chips. The interior has a new headliner the footwells and carpet or spotless with no wear. The previous owner installed leather seta covers and door panels by JAX Interiors in GN color scheme with turboBuick logo stitched on the head rests. I do not know the condition of the seats. The seats are firm and tight with no seat noise front back or lateral movement issues. The dash is clean and perfect no cracks. Has a JVC radio/CD deck. Speakers are not hooked up. Here is a list of items and info provided by the previous owner: NEW MOTOR installed in 2006. When I got it there was 900 miles on the odometer. Current mileage is 39488 Applied Technologies Research (ATR) Hydraulic Cam RP314B…214/208-109 Applied Technologies Research (ATR) Stainless Steel Headers 51 Precision Turbocharger 42 injectors Larger (than the Garrett) Precision intercooler 28 stall spped converter 342 rear end Larger sway bars ATR coil springs 4 coil radiator. Portland Speed Industries is a master race and tuning shop in Hillsboro Oregon. I had them do the following work (receipts provided with sale): Idler arm left/right tie rod assembly adjustment sleeves Center link sway bar bushings sway bar link kit Rear main seal Oil pan gasket oil pump R&R Valve cover gasket manifold gaskets turbo outlet gasket Tranny filter kit Flow Master resonator repair fuel injector Alignment Custom EGR plate oil pressure switch Completely new wiring harness under hood R&R machine heads Performance intake manifold camshaft position sensor Ignition module Multilayer head gasket (4.06) alternator New head studs PSI did dyno runs before/after. Proof of results provided on sale or go to PSI's website and look in dyno archives: Engine produced 350hp at the wheels and 401.36 torque at 11 lbs of boost. Any low mileage GN for sale under 75k miles is going to need all this work done in short order due to tremendous under-hood heat that wears out components and quality of OEM parts. If you know about GN's they are high maintenance vehicles compared to a Honda but they offer performance opportunities which can be tempting. I have kept mine to a minimum so I am not selling a "racer" or "dragster" or some kind of backyard mechanic modified car. I run Mobil 1 and engine idles smoothly and rumbly (has a great sound of course) at 10-15 psi oil pressure at idle. Other notes to consider: Wheels are perfect no rust dents or flaking. 3" cold air intake and down pipe. Horn works! Crank windows. Air conditioning is cold. ITEMS NEEDING ATTENTION: Speedo is starting to buzz and jump a little. Speakers need to be hooked up to non-original stereo. EMAIL ME FOR A YOUTUBE LINK FOR A VIDEO ON THE GN.
