All the cool kids are doing it..., Low budget progress thread (Slow Race prep.) Options

[BMXerror]

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.

Good lord! I can't believe it's been a year and a half since I posted any progress... haven't really made much, is why. Where to start?.... Well, I started autocrossing with SCCA in may of '09 and quickly learned how slow my car and myself really are amidst a competitive group. As discouraged as I was, I realized that that's where I needed to be to improve my skills, both on the driving and preparation side. However, I ended up focusing a lot of my money and efforts into track time, and little got done with the car.
About May of 2010, the D-jet system really started getting bad. It was never really great with the modified engine, but the system started deteriorating rapidly to where it barely wanted to run. I decided to park it before it cost me an engine. I quickly realized I was faced with two options. Either spend to rebuild the ignition and injection systems and live with D-jet for even longer, or bite the bullet and go to SDS as I've wanted to do for years. Well, there was no cash for that. I was trying to buy a house, and my commuter car blew an engine shortly thereafter.
However, in August I was able to find a brand new SDS EM4-4F system (exactly what I wanted) on eBay for cheap. It was a guy in Australia who bought it for a project that never got that far. With shipping back to the US I paid $1140. Plus I had to ship it to SDS and have some rework done for some of the options I wanted, as well as a V17 chip upgrade. That was another $388. All in all, I figure I saved about $500 on a fully loaded system.
Of course, as life goes, I got my house the very next month, and for a while it was very hard to find time and money to put into the install. However, I was try to spend one extra night a week in the machine shop building the brackets and stuff I need for the sensors and injectors. So anyways, in the past 4 or so months, this is what I've come up with.

The first custom part I machined is a mount for the TPS. Luckily, the 'D' pattern on the TPS is the same as the stock shaft. The shaft did need to be cut shorter, which took me about two minutes with an angle grinder and a cutoff wheel. The hard part was that the TPS plug is turned 90 degrees from the stock location towards the back of the engine. With the bell housing there, it gets a little tight to plug the loom in. So careful measurement had to be made to make sure everything would fit.
What I came up with was a two piece design that consisted of a machined block that mates to the TPS, and a sheet metal 't' that flips it 90 degrees and mounts the assembly to the stock TB.


TPS brackets. You can see that the sheet metal part was all done by hand. It's functional.

Assembled TPS mount alongside new TPS. You SDS guys will be familiar with that part.

Installed.
