I just changed the timing set on my 85 GN(converted to 87 IC). It just turned 50K miles so this was PM. It appears everything went back together as planned. I used a chain and gear set from TA Performance, aligned the gears "dot to dot" with the engine on TDC on compression, installed the new...

Driving the 85 GN, car running perfectly, come to a stop light engine stutters just slightly and SES light flashes. Runs fine to the next light, again engine stumbles and SES flashes a couple times very quickly. Leave light go about one mile car stalls. Push to side of the road, turns over fine...

Right now there are two different eBay auctions going on for base Regals that are advertised as G.N.s. it just pisses me to see these idiots misrepresent these run of the mill cars as something they are not...

For those that never venture over into the "Hybrid" forum, take a minute and check out my Turbo-LGN. It was quite a hit at Cruzin the Coast. David has done some real magic turning this car into what Buick should have done when they borrowed the "Grand National" badge.

Curious to see if any other Buick owners will be at Cruzin the Coast this year. For anyone who doesn't know, it's a huge event along the MS coast around the Biloxi area Oct. 7-14 with as many as 6000 hot rods from around the country. I'm taking my GN and LGN down this year, it would be cool to...

Need a nice clean cover to fit stock turbo. Prefer good chrome but if not I can have it re-done.

Last night the GN started right up, ran perfect for about 10 seconds, shuttered then died with total loss of all electric power. No lights, no radio, nothing as if the battery had been removed. I climbed under tonight and found one of the small wires broken and missing the connector terminal...

When cranking to start it will turn over normally then suddenly stop almost like the motor is locked. Release the key, try again and it turns over fine. If it doesn't start on the first several cranks it stops again (sometimes with a very small backfire or more like a cough through the exhaust)...

The ignition module under my Magnavox coil on my 86 LGN just took a crap on me so I followed the advice of some guys on the LeSabre site and switched it with a more readily available type II module with the 3 individual coils. Supposed to be slightly better spark, more reliable and certainly...

This is on my LGN but I'm hoping someone has seen a similar problem and can offer some help. I plugged a Genesis into my OBD port and when I connected the power supply to the battery the Genesis would not turn on and the engine started missing and died. With the engine running, every time we...

I've been a member for a long time, I don't post often but I've learned a lot from the gurus and try to pitch in to help out whenever I can. However, I've often seen someone ask a "dumb question" and usually get one of these responses: 1) completely ignored, or 2) "this dead horse has been...

Need a hardtop roof within driving distance from Memphis, TN. Must be rust and dent free. Not willing to pay shipping, must be able to pick up from Memphis (2- 3 hour drive max.)

I'm looking for a hood bump, I want to add it to my spare LGN hood once I get the turbo installed. I don't know if anyone is selling a repo metal or fiberglass one or if someone might have a good one taken from a damaged TR hood. If you can help or offer advice please send PM. Thanks, Hugh

Not turbo yet, just wanted to share. Got the LGN pretty well finished up except for the turbo and I/C that is to be done this fall. Looking forward to that but till then..........just a sweet daily ride.

I am beginning the restoration of my 86 Lesabre GN and need the following parts: Driver's side rear window air louvre Front air dam from 87-89 T-type Hood & trunk flat disk style Buick emblems Grill Dash Any interior parts for Lesabre Custom in factory grey cloth LF wheel opening molding...

Here's what I did: I swapped the turbos on my TTA and GN. The TTA has an external wastegate the GN does not. Because of this I had to use the exhaust part of the turbo on the existing car that it was already on. The TTA using the turbo from the GN and the external wastegate runs good and builds...

Next month I'm taking the TTA to a SCCA sponsored event where I will on a 1.6 mile,9 turn road course. I was strongly advised by the safety director to "completely flush and refill" my brake fluid if it is more than 5 years old. Is there an easy way to completely drain and flush the lines and is...

At the seminar I heard him say that the TA belt is different because of the compressor being different and if you used a GN belt you would have problems. I did not get a chance to hear what "problems". My compressor has been changed because last summer I started getting a vibration when I turned...

I posted this in the internet fraud section but wanted as many of you guys to see it as possible since the auctions ends in a couple days. I noticed on this link the vin number shows an "A" in the 8th spot. I've asked for pictures under the hood but did not get any. Makes me curious...
