PERFORMANCE & ECONOMY (Manufacturer's figures)
Max speed: 150 mph.
Acceleration: 0 60 mph, 6.6 sec.
Fuel consumption: 22.1 mpg urban; 37.2 mpg at constant 56 mph; 30.4 mpg at 75 mph.
NOTE:
For turbo longevity it is recommended that the Sierra Cosworth along with all other turbocharged RS models run with fully synthetic oil. These types of oil give the necessary engine protection for the high temperatures attained in turbocharged vehicles.
TIGHTENING TORQUES
Remember it is as important to ensure that bolts are not over tightened as under tightened.

Stage One
1.Reprogrammed Management Chip.
2.Uprated waste gate.
3.Higher Temp. Spec spark plug's.
4.Air induction Kit.
This raise's the boost from the standard cars 9psi to between 13&15psi, and the reprogrammed chip remaps the fuel injection rate and ignition timing. Power should increase to about 280bhp and 260lb/ft of torque.Depending on where you purchase this would require about IRP400 of your hard earned dosh!
Stage Two
1.Reprogrammed Management Chip.
2.Uprated waste gate.
3.Higher Temp. Spec spark plug's.
4.Air induction Kit.
5.3 Bar Map sensor
6.Green Injectors(increased flow rate)
7.Group A competition head gasket.
Runs at around 18psi and makes 320bhp 295lb /ft torque.This will set your spending to over a IRP1000!
Stage Three
1.Reprogrammed Management Chip.
2.Uprated waste gate.
3.Higher Temp. Spec spark plug's.
4.Air induction Kit.
5.3 Bar Map sensor
6.Green Injectors(increased flow rate)
7.Group A competition head gasket.
8.Wire ringed block.
9.Hybrid Turbo (Garrett T35).
10. 3 Inch Mongoose exhaust system with RS500 exhaust manifold.
Runs 20-22 psi and makes 345bhp and 310lb/ft torque. This is about as far as you can go before open heart (and not to mention wallet!) surgery is required.To get to this level just gather up about IRP2000! Sound's like alot but the power and torque are serious!
