Hey guys

Picked this up from San Diego about a month ago and have spent way too much money on it already :cool:

I added the tint, and I already swapped the wheels to 86-87 style.

Just installed a racetronix double pumper kit
120# injectors
and got a new tt tweak for 25psi on e85 :D

here is a list of what it had before I got it

1985 Grand National, converted to Intercooled using 87 GN parts. Can run on regular pump gas or E85. Running e85 now, at sitting safely at 18-19 psi for daily driving. Last time at the track, without changing anything, (17-18 psi, DOT's, old plugs, not touching the chip, etc) it would still do ~12.70 1/4 times. Of course that was with like 3.x 60ft times as it wouldn't hook with DOT's. With drag radials it has done 1.8 60', which still could use some improvement.

This car is ready to drive anywhere. I have driven cross country in it, and it has never left me stranded.

114,xxx miles, although engine, trans, suspension, brakes, etc are all rebuilt.
Sportsroof (moon roof/sun roof), G-80 Posi, Cruise, Power windows, etc all works. AC needs recharged. (Converted to 134)
Rebuilt Engine with less than 20k. I just did new intake, oil pan, and valve covers as it had a tiny leak.
STD/STD Turbo cross drilled crank
Double roller timing set
TRW Forged pistons .030 over
Stock rods, polished beams, shot peened, ARP bolts
Plasma moly rings
Edelbrock 204/214 cam and lifters
New Comp springs, retainers, keepers
Hardened rocker arm shafts with RJC rocker braces
Extreme ported big valve heads. Epoxied floors to smooth/direct airflow
Head cut to use Felpro 1007 lockwire head gaskets (and I do use them)
ARP head bolts
Stock upper plenum, modified w/ epoxy and an aluminum plate curved to direct airflow
New water pump installed with new motor, 160 degree thermostat, hoses, clamps, etc
Brand new gear reduction mini starter installed January 2013.

200R4 (4 speed auto) Rebuilt about 15k ago “Bullet Proof” By Chance & Sons Transmissions in Haysville, KS (of Neal Chance Racing Transmissions/ Converters) (cost almost $3,000!)
Neal Chance converter 3,000 stall

after the injector upgrade and ecm mod I noticed my #2 injector was not pulsing nearly the same intensity as the rest so I had it cleaned and tested with another. Everything checked out just fine. So I ordered myself a new injector harness and hotwire kit from racetronix. All injectors are now working the same :)

But I am having issues with the car wanting to overheat. I am running no tstat, dual ramcharger fans, and a fbody radiator.

just took it out and after getting on it there was coolant all over my engine bay, not sure what it could be.

It has a new waterpump on it as well.

ambient temp is around 85 so its not too hot

but on a good note, being able to do burnouts at 60mph with 275 drag radials is fun lol
