French,
If you plan on pulling, then you need to look into what class you want to pull in. That will dictate what size turbo you need and how much fuel you want.
If you want to drag race, then it is open.
Your best option is a set of compounds, something like our Performance 64 Compounds. It will use a 64mm for the high pressure charger and a 74mm low pressure charger. This setup will be a little laggy (starts to spool around 1800 rpms) or we can do the Performance 62, which uses a 62mm for the high pressure and starts spooling around 1500 rpms.
As far as a single, you will need a 72 or a 74, but you will have a very difficult time getting it to light. A 2500 to 3000 stall converter will probably be your best option if you are trying to stay away from the gas.
Let me know if you are interested in a set of compounds. We are looking for testers to help us fine tune the setups. In exchange for you help, we are offering a pretty good discount. Right now they are 5900 + 100 for shipping.
