    They used to call my 90' LX Coupe a "Wednesday Car" at the dealership where I worked....it ran a string of 8.8's bone stock with 10-holes on it.

    Eventually Ran lower 8.30's (8.27 one time...but was never able to back it up)...
    - short belt (and cut-loose fan clutch)
    - 3.73's and modded stock carrier (extra clutches)
    - Hoosier Dirt-balls (still on 10-holes)
    - removed front sway-bar
    - Homemade rear traction arms
    - removed everything that didn't have a significant purpose...sound deadening, all insulation under the carpet, spare, jack, etc. Also removed the power factory tweed seats and replaced with base stuff out of a 4-cyl car.
    - ported stock MAF
    - Extrude honed stock intake
    - 15 degrees initial timing
    - Offroad H and 2-chamber Flowmasters (not a catback, just replacement mufflers)
    - 100 octane unleaded fuel...never more than 5-gallons of fuel at a time (minimal for weight savings but also enough to help with transfer)
    - Homemade CAI
    - Motorsport clutch and lightweight flywheel
    - Hurst shifter

    Probably forgetting some things...it's been a long time...I would try any little thing back then. I was basically living in the magazines, spending every weekend at the street races and/or Kennedale, and also experiementing constantly (getting A LOT of seat time in it). The car lived in one of my stalls at the dealership and I was fucking with it during any bit of downtime I had at work. It had never had a valve cover off when it was running that setup....it had right around 35K-36K miles. I started doing more when that first stage of warranty went away.

    I eventually started playing with nitrous....the same setup above with a 100hp pill and stock fuel pump went a best of 7.81 on 9 degrees initial timing....eventually switched to Weld wheels with skinnies up front and 26x9 ET Drags on 8" rears....changed out the fuel pump (I want to say to only a 155lph, but I don't recall exactly on that) upped the pill to 150hp...switched to 4-cylinder springs up front and some "modded" stock struts and bolt-in frame connectors....went a best of 7.60 in that shape, backed up several times but wasn't nearly as consistent as it was on the 100hp pill....and I tried & tried to get a 7.5x pass out of it but it never happened! Some of the things I tried actually slowed the car down....stuff like trying to open the exhaust behind the H-pipe. I also remember that it liked to be short shifted 2-3 and 3-4.

        tune to lean it out a bit
        do some sorta straight through exhaust
        LT headers would probably do wonders to hep pull the exhaust charge out, considering you are in love with e7s

          I have an 89' gt with a 5spd. I had stock motor, ported e7's, small lunati cam, 24lbs injesctors, 190lph pump, cobra intake, 70 tbody, 73 c&l mass air meter, long tube headers, offroad hpipe, and 373 gears. It ran 8.20's with a proshifted t5. I put a 100 shot on it and ran 7.60's with a 1.55 60ft. It had 180,000 miles on it and I ran 30 plus bottles through it. I got tired of all the stock shit and put a built 331 carbed with a c4. You will get tired of the stock shit and move on like the rest of us.

            Yeah but it took you cam, intake, ported heads and full bolt ons to run what I want to run with, factory stock shit.

            The stock heads are crap, but I'd like to get the car dialed in and then do h/c/I.

                E7's that I ported myself and put stronger springs on. The cobra intake only knocked off .10. The cam was only a .510 lift cam.

                      When my car still had the e7s and all stock with 200K plus miles I ran 8.50s on slicks on motor. I put a dry kit on it and ran 7.50s all night pilled to a 150 shot. I then borrowed a set of front runners from a buddy and ran a 7.30 at 95. Now my car is still stock speed density but with trickflow heads. I was suprised though at the et loss from the front runners

                        i know its wasted time to ask but why put so much time and effort into a stock motor? i understand it is cheap and we can all go for cheap but it is pointless. save your effort and just put a bottle on it. when it blows up upgrade like everyone else has because we have all tried what you are wanting and we all learned real quick that stock is SLOW!

                          I have a set of front runners but one of the tire split while coming home one night from work. I figure knocking off the weight and more narrow of a tire would make a world of differance compared to 245/50 ponys.. Lol

                            Not because it's cheap, just something I want to do. It's not the easiest or fastest route but I think it's fun.

                            I'll eventually build a motor, but mine runs fine and gets me in enough trouble.
