  • Project: PBR-Built Z/28

    I officially decided that I am going a new direction with my car and so I figured I would give you guys a project thread. I am also open to suggestions on everything of course! Basically, I've gotten hooked on road racing and autocross this summer and so that is the direction I will be going with my modifications. I also went through the whole "should I sell my car and get a C5?" question, but after considering the overall value of my car, and how well it already performed on the track as is (Full weight at 3700 lbs, stock worn out suspension, crappy tires, etc) ... I decided I should just stick with what ive got. After a couple track days it was already obvious how good of a fit my cam selection was for this purpose, so why go back to the drawing board?

    My basic plan for the car is:

    1) Stick with my existing driveline combo for now and focus on making the best use of it.
    2) Cut weight. Alot of weight. 500 pounds while staying with a mostly complete interior is the goal.
    3) Add road-race modifications such as supsension, brakes, PS coolers, etc.
    4) Maintain street-friendliness and cruisability, and also maintain[and/or restore] show quality as well. But not too worried about long-trip comforts and noise levels.

    Here is what I am starting with, as if you all didn't know the car already:

    My current budget is $0. That will change when I get a job, but there is still plenty I can do towards my goal within that budget


    Day 1 working on the car:


    Removed subwoofer and amplifier. Never used it much anymore anyway. I can't find our household scale right now but I plan on weighing everything I remove and totalling it all up. For now I am guessing 30-40 pounds was saved here. The subwoofer is for sale too!

    you'll also notice I removed a couple unnecessary pieces from the back of the car, such as the insulation above the fuel pump, carpet where the sub was, and plastic piece on the bottom of the trunk which is never visible anyway.

    I also removed the spare tire, jack, and whatever was with it. Probably an easy 40 pounds here as well:

    Next, I spent a good 6-8 hours lightly "restoring" my interior. Several parts were loose or falling apart. I started by removing all the old wiring from my stereo and any old gauge wiring no longer in use. I also corrected no less than 15 interior pieces that afternoon, such as the notorious window switch modules that pop out and knee bolsters that have seen better days. Several missing screws were replaced and another several were tightened up. I also found a terrible speaker install job from the previous owner 7 years ago who had mounted the speaker brackets directly over the MDF screws, which wasn't providing any seal whatsover. This required removal, modification, and replacement of each speaker, and the result is a stereo that sounds 10x better - and i don't feel like I need a subwoofer anymore either! Overall, my interior is in MUCH better condition now which is very satisfying. TLC that was long overdue, just needed to find the time to do it.

    The last thing I fixed was a vacuum leak ive had since I did my cam swap. I had lost the hose for my fuel pressure regulator during the install. This was tricking my fuel system into thinking that it was always supplying pressure for WOT. Also, it was causing the nearby HVAC vacuum feed to not operate correctly, meaning my vents have been stuck in one place for two years. Well, I finally found this missing vacuum line in the attic and replaced it. HVAC controls are now working again On the downside, it also brought another problem to the surface which is that my AC is no longer working. However, after not being used for 2 years, Im thinking it could be just a lack of pressure in the system preventing the compressor from kicking on. I'd like to figure this out so I can sell my AC system as a complete functioning unit.

    Picture of the line that was missing:



    More to come! Next project is likely going to be replacing the ABS module with a proportioning valve so i can adjust the balance of my brakes at the track. ABS never kicked on for me at the track, so it didnt prove very useful and the module also has a pretty significant weight to it. I also want to relocate my battery to the trunk for better weight distribution.

    Wow - you've been driving around with the fuel pressure regulator thinking you were WOT all this time? If you had a leak or no freon for the compressor, yeah it won't kick on... that's the problem I have with my AC right now - a leak somewhere in the system (those recharge cans that come with gauges show it's leaking down in pressure) and it gets to the point that the compressor won't even turn on anymore.

    Definitely looking forward to reading more progress on this.

      the FP thing didnt seem to affect much, but yes!

      I don't think I have an AC leak, but you never know after moving all that stuff around during the swap. It worked perfect, ice cold, before the car went under the knife.

        I made a new friend in RoadRacing who was my instructor at BeaveRun. He runs with Sam Strano and they basically have their cars set-up identical and work amazing. I will try to get the shock/spring combo they run or if you are comfortable, feel free to give Sam a call and I know he offers set-up help for free. For brakes, I would do stock C5 brake conversion as they can be had for a couple hundred bucks. Then run some Hawk DTC 70 pads up front, 60's out back. If you want tires that you can multi-purpose with, I think the NT-05 might be a good choice although I've never used them or else I know you can't go wrong with pilot sports. Weight reduction will be an awesome idea. After that I mean you are set-up.... just tweak in that suspension, add some brakes and tires, make sure your oil and fluids are staying cool and give her hell!

          Thanks jonny! whenever you can get that suspension info that would be great, but no hurry since i don't have the cash right now anyway! C5 brakes, power steering coolers, NT05s and the rest will all be in the works!

            Hey Joel my brother runs NASA with his 82 ta and we are going to be at gingerman raceway in two weekends, the 25th I believe. It is a spectator racing event so anybody can go. I will be running my car as well as my buddy with his 02 WS6. Should be fun if your interested(or anybody else for that matter!) www.spectator-racing.com.

            I may also be able to get you guys better pricing! I will check that out.

            Ok, sorry for stealing your thread. Back to your regularly scheduled program.

            Oh yeah and good luck with the project! Road racing is absolutely AWESOME!

              Jonny is going to be running his vette out there that weekend, so there is a good chance I might come watch! Would race if I had $ but kinda broke right now.

                There is a book called 1993-2002 F Body Performance handbook. It costs like 18 dollars off line and it breaks down everything. I wanna order me one.

                  Hey Joel....looking forward to seeing your project progress. If I can offer one suggestion though....keep everything you remove from the car. A long time ago, I removed alot of unwanted weight from my car to make it lighter and thus faster......lol. Obviously the direction that I took my car in has changed over the years so I'm glad I hung onto all those little items.

                      I assume you talking about things like AC/ABS/cruise/spare tire? or interior parts? I dont plan on removing much more from the interior than i already have. maybe some more carpet insulation... but those couple pieces arent worth much on the market anyway.

                      If i take my back seats out I am going to keep them for sure, otherwise I am also considering selling the leather all together and getting a set of racing seats.
