hi all, ive got an e reg 90 fitted with the 2.5na engine although its in a good condition it is simply too powerless at times. ive been given a turbo,exhaust manifold and inlet off of a 19j. from what i can gather apart from the later 19j's the engine was the same. i know many people hate 19j's with a passion but several people i know have never experienced a problem. are there any differences between the engines or not? hope someone knows more, thanks
