my mate has always wanted a 2.7 in an e30. i just wondered what the horsepower gain was to go from 2.5 to 2.7 without cams or anything just standard to standard ?

My 2.7 gave 189BHP.Sandard eta bottom end,320 head with 325 cam,325 inlet injectors and FPR and a Miller MAF. The main gain is to torque,the engine pulls strongly from 2000rpm.
