One of the members in our Auto-x club is a race car fabricator. He mentioned that he set up custom fuel injection systems. He happened to have his Nissan Silvia outside and offered to show us his work. The intake is a custom built aluminum unit, it uses 1 3/4" runners and about a 4" round plenum. He attaches a Nissan 240sx throttle body, bosses the runners and cutom builds the fuel rail, custom connector to the MAF and bends the intake tube to place the filter in a good cool spot. He uses the injectors, computer and O2 sensor from the 240sx as well. He has built several of the cars for our club members and put cages in others, built custom headers and intakes for other people, etc... so I'm confident in his fabrication skills. His Silvia ran extremely well and he said with very little tuning the plugs were perfect.
He said he could build one using basically the same nissan parts and a custom intake, then do the initial tuning for me for about $1000. Does this sound like a reasonable amount? The only problem I have is that the computer is only tunable to a certain degree, and it is used equipment that I could pick up at the pull and save for under $50 with the exclusion of the custom intake and fuel rail.
He also builds roll cages and said his normal price is about $1000 for a good 8 or 10 point (he would have to see the car to determine the best setup) that is SCCA road race legal. I have seen his cages and they are works of art. They are very tight to the body and the welds are nice and fluid. I'm not sure his price on headers, but they would probably be a few hundred.
