The Rtek7 ECU Mods look promising. I was going to order the 1.5 kit until I ran some fuel calculations and recently became concerned with running too lean with the setup that i am planning. I have a rare gem, a totally stock 87 T2 with 80,000 miles. My plan is to start mild and go stronger on the engine build. Currently i am aiming to use the stock turbo with a waste-gate mod until i can afford to buy a better turbo. At them moment I am planning to run a semi free flowing exhaust; cork sport 80mm down pipe ceramic honey comb cat, Hallman manual boost controller with in cab adjustment, Walbro 255 fuel pump and K&N Intake. My concern at the moment is if 4 x 550cc injectors will be capable of safely handling the power requirements with a Rtek7 1.5 and is the 2.x mod capable of running running my setup. I would enjoy the tune ability of the 2.0 system but would prefer to save money with the 1.5 for the time being. My research has led me to believe that i would probably be better off going with the 1.7 version ECU and 720cc secondaries but as i am "wet behind the ears" with rotary mods i thought it would be best to get a second opinion of someone more experienced with this. My feeling at the moment is that 720cc injectors may be a bit premature and i am just overshooting my expectations, but what i have read makes me think the transition to an upgraded turbo will be easier by going to the 2.x ecu. Any assistance would be greatly appreciated.
