Up for sale is my 1987 Buick Grand National hardtop. I have owned this car the last 7 years. The motor, trans, and rear have less than 2,500 miles on them. I would not hesitate to drive this car across the country at any point. The A/C works great, but has the typical leak at the hose near the...

Anyone have the tightening sequence and torque specs of the rear end cover and trans pan?

Finally got my new combo out for a run. Was only able to make one pass for the day, I got some knock up top and had to let off and brake right before the finish, still figuring out the issue. This was with the combo below on 23psi, single M15 alkycontrol, 10.6 target AFR. Full weight GN with...

Finally logged a pass on the new setup and had the car go lean for a split second right at the end of the 1/4 mile giving me some knock. Nothing in the powerlogger that I can see indicates what caused it. I did not do any back up runs after this. This is with a TT6.1 chip and WBO2 AFR tracking...

Tried searching with no luck. What's the torque spec for the 4 driveshaft bolts? I have my stock steel one out and a Kirban aluminum on the way, but may have to drop the steel one back in for BG Saturday...

Will a PTC 9.5"NL 3200 be enough converter to spool this turbo up fast? Was originally set on a dbb but saving $900 makes more sense if I can spool it fairly quick. Also, is the journal bearing version of this turbo actually the older 6765? Hartline and Full Throttle seem to have it listed...

Rather than cludder up Daniel Jost's thread here's another one. :D Heading to the dyno next Friday for a few runs. Mods are in my sig. Running 93/alkycontrol twin nozzle at 5.5 setting, 25psi, 10.5 A/F, 75-80% IDC on 60's, 21* timing. One thing I noticed is that my converter slip seems to...

I recall reading that most people disconnect their volt booster when running methanol (I did too) as it can cause the pump to spray too much and bog down the motor, and thus slower times/less hp. I'm going to the dyno next Friday and was wondering if I should throw my Caspers volt booster back...

Finally got around to datalogging a quick WOT run....didn't run it quite as high as I wanted. This is with the mods in my sig set at 10.4 target A/F...psi(4) is fuel pressure. Should be hitting a dyno soon to really see where she's at.

Having a few issues with my HVAC setup (manual). For one it will only blow out the defrost and floor vents. I've tested all my check valves with a vacuum pump, and fixed a vacuum leak on one of the plastic lines that goes into the cabin to the HVAC system, but still haven't fixed it. The...

Finally got around to getting the rear wheels on (had to intall Mosers, 3.5" ARP studs, etc. These are 15x10 with 5.0BS and a 7/16" spacer, 275/60/15 ET Streets. NO frame mods, and NO fender rolling. Doesn't touch or rub around corners or under a hard launch. I also run airbags in the back.

What diff lube does everyone use for their lockers? I'm specifically running a Richmond Powertrax locker with Moser 28 splines.

Lost your TR keys the morning you're planning on heading to a car show? :rolleyes: Guess I won't be making it to this one :( Now I have to decide whether to get a locksmith, or get a new key and tumbler...

Have a few issues with the HVAC system I'd like to work out after getting my car back together - 1) No matter what setting I have it on, it only blows out the defrost vents. This is something new that happened after the motor rebuild. Thinking I must have some check valve or vacuum line...

Specifically the Driver’s side top. I know there are two springs holding the bottom in, and the passenger side top has a mount tab with a screw clamp. The only thing I see on the driver’s side is a small guide in the center of the side? Top of my grill came loose (that’s a whole different...

Just started driving my car around with the new PL, SM2.2 update, and LC-1 setup. The sensor heats up fine (shows 7.3:1 while heating up, then starts reading correctly), but after a certain amount of driving around, it could be 10 minutes or 45 minutes, all of a sudden it starts displaying a...

I just put in a Speedhut tachometer and plugged the signal wire into that green connector right near the back of the alternator, as I had seen on here before. Problem is, when I compare it to my Scanmaster rpm reading, the speedhut gauge is about 25% lower rpm. Just by ear I can tell that the...

I'm about to order some 15x10 4.5BS wheels for my 87 GN but need to verify - Right now the car has stock drums, but the plan in the very near future is to switch to Baer SS4 brakes front and rear. Will this affect my backspacing at all? I know the 15x10 wheels are going to be a tight fit, so I...

Debating on whether to go ahead and drop the money on roller rockers or stick with the stockers. Combo - stock block, crank, rods, wiseco pistons, champion ported irons, champion intake, revolution X 210/215 roller cam, stock headers, CPT66BB, razors dual nozzle alky, TT 6.0 and...

I get annoyed seeing these types of threads, but with my car gone for almost a year now, I'm getting really anxious to see what it could possibly do. :redface: I've got a real good idea, but just looking for people with similar combos or more experience than me. 109 .030 over forged wiseco...
