Is anyone familiar with the nature of the electronic fuel injection systems on the new American cars? I'm doing some tinkering with my engine and am looking for some basic components (injector nozzles, high pressure pumps, regulators, and so on) to build around. I got prices on the Lucas system parts (I'm working on a British car) which knocked my socks off. A parts place wanted $90 apiece for the INJECTORS. Authenticity is nice, but only up to a point. So, if anyone knows anything about an AMERICAN system that works well, I'd appreciate hearing from you. I'm also looking for automotive sensors for manifold pressure, air temperature, and exhaust gas oxygen content. I'm trying a new approach to sliding a high-performance car past California emissions laws: I'm going to try to COMPLY WITH THE REQUIREMENTS! I'll be pleased to let anyone know how it all turns out, although it may be a few months before I get some results.

I will be anxious to hear how your homebrew system works out. I don't really have any good suggestions on injection systems but thought I might mention a few things on the pollution equipment. A good oxygen sensor is used on the Volvo and I believe is made by Bosch. This is the Lamba-Sond which is used to measure the lambda point of engine operation. This is a point at which the engine operates which produces a mixture of gasses which can be handled by a three way catalytic converter. The lambda point is a very exacting mixture and so the air/fuel mixture must be very carefully controlled. This is done with the Lambda Sond and a magic black box to properly control the fuel mixture. This with the three way converter and air pump is probably your best bet to meet the pollution requirements. The only problem is ignition timing must be somewhat retarded as well and so perfomance will drop. I don't think you will have quite the performance you had before. You might also look into the methods used on the new Mustang or some other American models where performance levels are beginning to approach pre pollution days. Keith Bauer White Tiger Racing
