Thank you Hemi!
The engine has yet to have been gone into. It's got close to 48k original miles. Mods are as follows:
TE44 Turbo (set at 22# at the moment), GNX/Turbo Trans Am Dutt-Neck Intercooler, CK Performance Shift Kit, RJC Racing 3" Downpipe / Test Pipe, Up Pipe, 3" MAF Pipe, Power Plate, Boost Regulator, Accufab Fuel Pressue Regulator, Razor's Alky Control Kit (Methanol Injection), TurboTweak Chip, 60# Mototron Fuel Injectors, Hot-Wired Fuel Pump, LS1 MAF & MAF Translator, Pypes Cat-Back Exhaust, BeCool Radiator setup & the ole Spectra Air Filter.
I have no real numbers as far as a dyno goes. And the car has yet to see a drag strip. But bone stock, they ran low 14s with the factory 14# of boost. I figure with the mods I've got, it should be significantly quicker now. LOL!
Grand National & GNX differences... Most of them were appearance differences. The GNX came with functional fender vents (heat extractors), fender flares, 16" mesh wheels similar to GTA Trans Am wheels (but black), GNX badges on the grille & rear bumper, a custom gauge setup with Stewart Warner gauges & a GNX production number plaque on the dash.
Here are a couple of pics of a GN & GNX for comparison:
As far as performance differences, the X had a upgraded turbo & intercooler as well as a more aggressively tuned chip along with a pretty intense rear suspension setup. These differences combined with the 16X8 wheels & tries allowing for a better footprint on the pavement made the car run low 13s in bone stock trim. Not too shabby for V6 in 1987.
