We have been doing some homework over the past couple days working on a set of rules for the Altered farm class. We have decided to go with a "Box Turbo Rule" We have a turbo manufacturer who has agreed to supply these turbos to us at a reasonable price and will have them labeled and numbered with a tamper resistant nut on the compressor wheel. The turbo being supplied will be a S-300 Borg Warner with a billet thrust bearing installed and a 2.4 inlet. By buying these turbos in bulk we are able to get them for $600 with shipping. Any tampering with one of these turbos after it has been installed and issued to the competitor will result in a one year suspension from the class. You must run one of these turbos to run in the class. (no exceptions)
To order a turbo you can call me @ 804-443-1903 or 804-514-5432.
