SR20 Turbo Conversion

 


 

Updated - 21st October 2007

Before the major work begins, we wanted to see what the existing MA10 engine and modifications produced on the rolling road. The MA10 is a 1.0 engine with 50BHP. 
  
The modifications include some Magnecor 85mm HT leads, K&N element filter, a 4-1 outlet manifold and a custom made 3" backbox, all fitted to an engine which has done 115,000 miles.
  
Several people predicted a loss in horsepower due to the age & mileage, but I'm pleased to reveal that gains were made.
  
The rolling road results showed some increased over the stock BHP & Torque figures, with the max power of 61.1HP being produced at 6200rpm and torque from 2000rpm to 3500rpm. 
  
The power remained above stock BHP from 4500rpm until the test ended at 7200rpm. The car's standard redline, which is not limited, is 6000rpm on the 1.0.
  
Now the major work can continue and I hope the next time the car is on a rolling road, we'll be seeing horsepower in the 150BHP region, after the transplant is completed.
