*SOLD* 1987 Buick Grand National T-Top, 2nd owner 99,120 miles. Stock longblock, turbo, ECU, Trans. Lots of really nice bolt-ons. Interior is in fantastic shape. Exterior paint looks fantastic but does have the normal pits, swirls, and chips you'd expect from a black car with this mileage...

I haven't driven my car in awhile(traveling and what not) and i just got done replacing the water pump. everythings running smoothly at idle, blm's are ok, steady vacuum. I went out to open it up and as soon as it seems like its gonna build boost it starts surging, sputtering and breaking up...

i was replacing my brake switch and i noticed what looks kind of like a factory connector. its two piece, the black piece has a brown and a blue wire going into it, thats connected to a clearish white connector that has what looks like a small resistor jumpered to it. the blue wire from the...

i got the dreaded drivers side manifold crack. I'd rather not weld it and now that ATR went away i was wondering what other stainless replacement options i have?

does anyone make a ball bearing TA-49 or is there a brand/model that is equivalent to the TA-49 turbo with ball bearings? also it would have to be for an internal wastegate(3" THDP). a water cooled option would be nice too.

i've been having a problem where at speed the t/c seems to lock and unlock randomly. i replaced the TCC solenoid with a new GM part and it is still doing it. what else could be causing a random unlock-relock of the torque converter? the transmission and converter are stock. this is an '87 GN...

i've upgraded all the ancillary stuff on my 87(intercooler, injectors etc) so i'm ready to get into buying a turbo. i was looking at the 60-1 stage V .63 a/r ball bearing turbo from turbonetics. the guy on the phone said that i would have to use an external wastegate setup if i went with this...

i was having the same problems i've seen on here in a bunch of other threads with ignition problems. car would pop sputter or cut out randomly while driving the check engine light would come on( i think it was code 43, gnttype.org is down i can't remember).This started happening 6-7 months after...

i went to gmpartsdirect and it said something about it being a special order item or the part number (8639900) was incorrect. is that the right Part# and if it is does anyone stock this thing? i'm also going to get the art car 2qt upgrade pan kit.

my 87 GN has been stalling out a lot more recently at lights. my scanmaster shows everythings fine. car is tuned up and runs every smooth and otherwise has great drivability. TPS .44 IAC under 50 blm's ~128 vacuum is consistant and hasn't changed any. fuel pressure ~40lbs at idle with...

i'd like to upgrade my sound system a bit in my GN. its all stock. problem is i really like having it still looking stock on the inside. so i was wondering if keeping the stock concert sound stereo, upgrading all the speakers and throwing in a modulated cd changer in the trunk would be a good...

when i put the car into D from park or neutral i get a quick metallic clunk sound. i was wondering if this is the transmission mount? i've got a HR drivers side motor mount and a stock passenger.

i go to swap out my stock actuator with the adjustable one i have. go to take the first bolt off and BAM the damn thing backs out straight into the freaking oil drain line. no way to get it off without taking the two bolts off the drain line and pushing it out of the way. so much for my 20...

anyway to test the actuator? car overboosts right now i have a terry houston 3" down pipe, stock turbo, stock actuator and a RJC boost controller plumbed directly between the compressor and actuator. the car always overboosts. i checked the arm on the downpipe and it opens and closes with no...

AND I COULDN'T BE HAPPIER! no more wishy washey power masters, i have a consistant brake pedal ALL THE TIME. the swap was not that bad and i didn't even remove the seat. just takes time, patience and a few breaks to let my arms rest from being kind of upside down in the floor board...

i was just test fitting all the connections on my trans + and my lt1 maf and it plugs into the lt1 maf fine. but i had to use the short adapter the trans + came with between the factory maf plug and the trans plug plug because the regualr trans plus wire won't connect directly to the harness...

just wondering what make and model external tranny cooler everyone is running. if they like it and how difficult it was to fab anything up and install. i'm running a f-body radiator too.

i don't have an impact and this is one of my last pullies to install, can i get it off with a large 15/16 socket and wedging the pulley from moving?

i'll be there, i have two spots reserved :)

well i've upgraded to the f-body radiator, i'm throwing on the RJC pulley set and then i'm putting in the PTE stock location intercooler. is this i/c fan really necessary anymore?
