My 87 Grand National Build and 99 GT

I was asked to share some pics of my 87 grand national resto in my introduction thread. I thought I'd post it up in this forum as it seems the most relevant.

Anyways 87 buick grand national. As most of you know it comes with a turbo 3.8l v6 from factory. rated somewhere around 260HP stock. simple bolt on get you massive gains from this black beauty.

Anyways picked mine up last year. took it to the track a couple of times and ran 11.9 as my best time. I'm not the most experienced driver out there and it forsure can launch a ton better but I was happy with that performance.

Winter came and I started to tear apart the interior. wanted to replace carpet, get the seats re done etc.. pulled out the carpet and the floor came with it.
completely rotten.

Previous owner undercoated it and didnt clean and prep the surface before applying and trapped all the grime/moisture underneath. It is a t-top car so that fed the fire for a while.

Heres some pics. its been a long journey finding nothing but surprises. Wheel wells were pretty bad. but we are through cutting and into replacing now!

Shes plenty dusty as you can imagine with the cutting grinding welding sweeping etc! not touching it and trying to keep "little' hands off as nothing good will come to the paint when hand meets metal shards meets paint.....:th_nervous:

Man that sure sucks about the floor on the Grand Natty...but it sure looks like it is coming around. What mods did you have on it when you ran an 11.9x? JW...

Nice looking bronzemist GT too...get those windows tinted and it'll look a ton better too ;)
 
I know! headlights need some upkeep. No time to do it!

eventually I want to do halo's or something. but there is a LONG list ahead of that
 
As for mods to the GN

Upgraded turbo to a Garret turbo. puts out 26lbs of boost
methanol injection.
injectors obviously upgraded when the meth went in.
hooker headers
art karr tranny w/b&m "sport" shifter
rear end swapped as well. dont remember at the moment what previous owner said.
I have it all documented somewhere


The previous owner shipped the whole thing out in 07 for a full rebuild.
block was honed not bored and replaced pistons rings heads etc..

I cant remember the build off the top of my head but it is quite impressive.
This thing is something else.
