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. |

Originally, when I decided that I wanted to go to SDS, I was just planning on using the stock D-jet injectors. However, since I bought a system from a private party, he had ordered injectors with it. He bought the Ford style 440cc 'Green Top' injectors, like so.
Even though it's overkill for the engine that's in the car right now, I decided to go ahead and install these. Two main reasons: I didn't want to change the injector plugs on the loom, and then have to change them back when I had enough engine that required bigger injectors. These are a standard size, and I can get them in many different flow rates. Also, they're new, and it's always best to use good components, even though there was no known problems with the old injectors. The way I decided to accomplish this is to bore and sleeve the manifolds to accept the new injectors, use the existing clamp, and machine port adapters for the backside (still in process). Manifold bored and counterbored to accept the sleeves. The fixturing on this part was a little interesting because the injectors rest at a 80 degree angle from the gasket face. Bore tolerance was .0005 for the press fit. Mark D. |
