Newbie Questions
I'm toying with concerting to Gotech sometime next year (too cold in Utah to think about it until Spring!). I had a few questions. My CA 1983 GTV6 with Alfa Heaven modified ECU(been on since 1985) and Greg's Air Cleaner setup.which I have owned since new has about 90K on it. It still is in a 2.5 configuration and probably will remain so as the engine works really well with no leaks and very little oil use. I have a few questions. First who are the US dealers for the Gotech and roughly what are the the retail prices for the product? Given that the car is a 2.5 would larger fuel rail runners make a difference coupled with the Gotech ecu? Does anyone make and sell larger runners? I suspect I would have to go to the upmarket injectors Greg (hopefully he will get them on to the new site soon) sells. Terry

Terry,
I am running the GoTech standard on a 3.0 with Greg's stage 2 injectors, my advice is on a 2.5, stay with your original injectors or have them sent off to RC and have them cleaned or get Greg's replacement inj. The stage 2 inj are sort of over kill for a stock 3.0, so a mostly stock 2.5 should be fine, and the better matched the inj are to the engine, the more adjustable GT will be. I would think about headers, doing away with the AFM does make the intake side flow better, so it would be good to make the exhaust flow a little better too. I am not sure you need to go to larger intake runners on a 2.5, take yours off and hone them out a little to clean up the welds and the sand casting, that makes a good difference.

Keep in mind that if you keep your stock injectors (low impedance) you need the "fly-back" configuration for GoTech. If you switch to stage 2 injectors from Greg, go with high impedance injectors and GoTech hooks right up. My verde runs GoTech Standard with Greg's high impedance stage 2 injectors and air intake.
