Just installed a 6BT in a '77 motorhome. The motor came out of a '90 Bluebird bus. It's equipped with a water to air cooler on top the intake. Would like to put a 351VG turbo to get a exhaust brake along with a little extra performance. Need to know if the wet intercooler will be sufficient to handle the upgrade. Or start looking into a air to air to hang out front. Installing a intercooler in front of the radiator will be quite a job. Thanks in advance for everything. Hope I put this thread in the proper place.
