Re: [doc] Engine "faff"?

["essexdick" <tny1964@xxxxxxx>]

     Hi martin whos got the other bae turbo,theres only  a few in the 
counntry? Also all that work for somthing that will probably prove

420bhp from cosworth,and it will run the same day after day,without 
worrying it may explode after a couple of bouts of abuse love from 
tony vin#3484 BAE turbo
