My turbo is installed on a 16v motor, with multiport injection. I used the stock ecu with bigger injectors, stock sensors, stock fuel pump, retarded timing a couple of degrees. All the info,with photos, is on my site. For more info on an 8 valve turbo install search turbo in archives, look for Wilds turbo build up. He did an 8 valve, with a Mega Squirt injection system. We both used IHI RHB5 turbos off an Ford Probe/ Mazda 6. Yes, I would do it again, but better with the knowledge I've gained from this build.
