CAN ANYONE TELL ME WHERE THE EXTRA HORSEPOWER COMES FROM ON THE GSI ENGINE? VAUXHALL SAY STANDARD 2.0 IS 136HP AND GSI IS 150HP. IS IT BECAUSE THERE ISN'T A CAT ON THE GSI? IF SO CAN I SAFELY TAKE OFF THE CAT ON MY '95 2.0 GLS CAV?
PLEASE HELP IF YOU CAN.
The engine managment is completely different from any other 2 litre Cav e.g. The 150BHP engine is has Sequential Fuel Injecion (SFI) and each injector is controlled independantly whereas yours will be controlled together.
There are many other differences so just removing the CAT wont get you the 150BHP.
