Well the porting is not an issue to have done, however it does require we have the bearings removed and then a new set pressed back in the blower casing. I dont know of anyone besides Saleen who will do it for us. Saleen wont because they are trying to head up their own ported blower program. However its really unknown if they will do it also, so im not sure where this stands.
I have a few ported cases, bearingless that i could even use on a core program.
