All good guys and Thanks for all the info on everyone's behalf. It's definitely answerd the main piece of the puzzle being which ecu to use as in factory stuff or aftermarket and It's going to be aftermarket for sure. The main reasons I asked about sensors is due to do they need to corespond with eachother in any way but by the looks of things according to you RSWEPN and you XRQTER1 it doesn't really matter which is cool. FPV TRANNY this car had a injected turbo 250 in it for close to 10 years ran consistent 10:40 @ 128mph not any sign of blo by, detonation, overheating or nothing. But if I wanted to go further it would have hurt it. As for the ass end it's got 9" will have 31 spline billets with a full spool mini tubbed, its got a 32mm sway bar and puttuing adjustable control arms. As for how it will go hooking up ?? Who knows I don't want to go modifying chassis so we will find out once it's all going.
