Water cooled turbo just means that there are coolant lines to the center section of the turbo to help cool it. If a turbo doesn't use coolant to help cool the center section then it is just an oil cooled turbo. An after cooler is typically called an intercooler.

well you can rev to say 4800rpm so a small turbo t-3 should spool at 2000rpm and have full boost threw out ,, im not affraid to go to 5000 on my motor plenty of room i hope im getting info on a few smaller turbos , then its off to ordering and making a header pipe , langdons sons has offenhauser carb tops , im wondering if carb tops , im wondering if my quadjet 2g carb will work ,

A mild setup with a carb and no electronic timing control should probably be limited to 6 psi. That's gonna wake the truck up quite a bit. Forged pistons are a good idea because they can live longer if something goes wrong. Cast pistons can work but they won't hold up if detonation starts or if the engine gets lean.

The stuff that applies to supercharger also applies to turbo when it comes to the carb setup. If the carb is after the turbo (blow through) then fuel pressure must be referenced to boost. Also the carb needs to be sealed up, either at the choke and throttle shafts or the whole thing needs to be mounted in a pressurized box. Carb float must be a solid material so it doesn't collapse, too. If the carb is placed before the turbo in a draw through design you eliminate the need for extra seals and regulated fuel pressure but responsiveness suffers some. IMO the draw through can be made to get better mileage though and is easier to set up. Draw through and intercooler don't play nice together but if you stick to 6 psi you won't need a cooler anyway. Either way make sure the carb can supply enough fuel.
