I have a 89 GXL with a street ported 13b-re with the stock turbos, full 3" exhaust, intake, front mounted intercooler, and thats about it off the top of my head as far as power options go. One day I plan on switching to a single turbo set-up, and im just wondering which stand alone would be the best to go with without money being in mind, and which is the best for the buck also. I have pretty much about no knowledge about stand alone's and the differences from one to the other. Personally I want to have a a good ECU that i can have the most flexability with. I appreciate anything that can be suggested.
