Hello I am quite new to doing mods on a turbo charged engine and would like some usefull information on the best modifications I can do to get more power from my car. I own a Saab 93 aero on an o3 plate which has the 2 litre engine pushing around 210 bhp.I have put a new larger exhaust and race cat on it so far. What modifications can I do to get more bang for my bucks Will a bigger intercooler help and also a new induction kit.

 

Bigger intercoolers are generally a good bet, although you might want to measure the intake temperatures to see how much room for improvement you get. Then you can turn up the boost - you'll want to watch both the air/fuel ratios (to be sure you're not running out of fuel) and the intake temperatures (if they start getting too high, it's going to need a larger turbo).
