I tried calling back, but the line was busy. I did not call Bell today and will do so tomorrow. Anyway, can you send the money order for the regulator sometime soon? I need to get money for the oversized valves. Anyway, I found the modified tube that runs from turbo to TB for use with the Big Throat TB. I will send it with the TB on Friday. I also have that pipe from the 300zx turbo that you will need to adapt up to the bigger turbo when you get it. I will include all of that with the TB at no charge! Call me tomorrow night and I will let you know the situation with the one-way valve. Later!
