I have always have had a love for the Subaru impreza. Well I have found one even with the issues that it had when I bought it . I had fallen in love! It's a 98 Subaru impreza L wagon 2.2l 5 speed. I bought it with the intentions to make it a rally/daily driver/ family car. Now with that said besides me getting a stage 2 clutch and a heavy duty flywheel to put in it I dont know what to do for the engine performance wise. I already have a cool air intake put on the motor and someday i want to twin turbo but for now what can i do thats some what cheap that will increase hp and torque. Again i am new to foreign cars so i dont know much about the performance aspect of them or where to look for parts etc..... So any ideas or pointers will help a great deal.

Welcome Cheap power is a little tricky because there isn't really much in the way of 'hidden power' that some simple mod will unleash on these vehicles. Delta cams can be an option. I'm not sure the twin turbo will fit, I think there's some issue the second turbo not fitting because it comes out of a left hand drive vehicle. In the early 90's people would use the postal bodies so that it would all fit. The cool air intakes many people use though stock on the soob draws the air in from the fender or under the hood lip where it is actually cool whereas the underhood filters seem to me to actually draw in warmer air.

run stickier tires

 

shed weight - lightweight crank pulley and flywheel, lighter rims(maybe not for rally cross) , take out seats, etc.

 

approx 1 hp for every 11 pounds of mass, 1 hp for every 4 lbs of rotating mass.

 

make certain you arent' riding on worn out struts or other suspension/braking bits.
