i've got a 1985 rx7 with a stock 12a in it right now and i've got about 3,000 to work with. I was curious what would be a better idea to just buy a jdm turbo II which I found for 1200 motor,ecu,tranny,intercooler. I would love to make mid 300's doubt I can reach that with the small chunk of change i've got to work with. And advice would be great this car will be driven 3 or 4 times a week. Not a daily but not really a weekend warrior either. It needs to retain some daily driving aspects like an idle. I know some porting can make idle extremely rough. Im new to the forum by the way great site lots of info to be sucked up.
