Well, with all the work that I'm doing to my car lately, I might as well start my own progress thread.
Backstory I bought 4702912742 from my pops about a year and a half ago for $600 dollars, but it wasn't a steal. It had been sitting for about five years and needed a lot of work. He A couple years later he had been looking for a teener for a little while and picked this one up cheap at a dealership in Pomona Ca. He drove it for a while, but it had tons of problems, and soon he decided to sell it. However, the person who test drove it blew first gear, and out to the back yard it was sent. Fast forward five years to when I was financially ready to get a car to start racing. Long story short, after deciding that I wanted the 914 instead of an older Miata, I told him I was interested. He said that if I bought him a set of mufflers for his bike, we'd call it even. After that I spent about another 4K just getting it drivable. I replace all four rotors, rebuilt all four calipers, replace the brake lines with braided steel, replaced the hard lines that I broke, replaced the master cylinder, resealed the motor (after my socket and extension locked the motor up), bought two trannies for it (the first one was no good), put a new clutch and pilot bearing in it, put new rubber on the ground (Khumos), fixed and lubed all kinds of latches and hinges to be able to get into all the various compartments, replaced most of the vacuum lines and fuel lines.... the list goes on. These were all just stock replacements to get it running well. I further had to fight with the injection system for a few months until I figured out that I had it hooked up wrong. (IMG:style_emoticons/default/headbang.gif) Of course, this is the very abbreviated version of the story. As anyone with one of these things knows, the words it takes to describe what parts you changed don't even come close to showing the blood, sweat, and yes, sometimes tears that you put into your work. But anyways, it is running decent now (the motor is still a little tired) so it's time to do some improvements. After all, racing is what I bought the thing for. So I'll try to bring anyone who cares up to date on some of the things I've been working on. Mark D. |

Well, since the rear suspension is well sorted now, I decided to get into the front. I happened across the pictured upper strut mounts, and decided that it was a good time to take out the stock mounts and reverse engineer them (I'm designing adjustable mounts). However in the process of trying to get the rusty struts out of the rusty mounts, I mushroomed the thread on the right side with my BFH. So the new mounts got new Koni yellows to match the rear. (IMG:style_emoticons/default/aktion035.gif)
In addition to all that, I got new tires all the way around as the Kumhos that I was running were rather hard and blistered. Dunlop Direzza Sport Z1 Star (Inhale) Specs, all the way around. So yesterday, I figured it'd be a good time to drop the ride height, equalize the camber, and do a four wheel alignment. The took about 8 hours, considering I've never done it before, and the frame is a bit tweaked, and EVERYTHING was out of adjustment. But the results look promising. 2 degrees negative camber in the rear, 1.5 in the front. I'm trying to put a few gentle miles on the tires before really pushing them, but I'm autocrossing next weekend, so we'll see how it works. The only thing unusual about this setup is the custom hardware that I had to machine to work with the new mounts. These 'retainers' are basically a 22mm nut no threads and a key cut in them. I tried making them out of aluminum, but that didn't work so well. So I went back and redesigned them to give them a little more meat, and made them out of steel. New mounts. Attached thumbnail(s) |
