Do what you want to your own car. People say alot of things about the wrx that are not true and what not. There are guys who have been running pullies on there car for 30,000 plus miles with no ill affect. Then there are people who say that if you remove the harmonic balancer and replace it with a pully you will kill your motor. The wrx does not have a harmonic blancer. People say the stock turbo is useless above 16psi but thats not true ethier.

 

I guessed that when you posted this in the naturally aspirated forum. I gave what people belive to be true for the wrx as an example. Do your homework and choose parts for your car based on solid research not everybodys personal opinions. The more you read all the forums you will start to see who knows what thier talking about and those who just repeat something they heard.Call up cobb tuning and talk to those guys they should get you on the right path.

 

You would appreciate most cold air intakes, Catback exhaust, and headers. I think once you get all that, the clutch and flywheel would be a good touch. I would also add a short throw shifter. People always forget wheels and suspension. The last probably has the most impact on performance and looks.

 

Yea i agree with Forestar if you dont have a good set of tires it doenst really matter what else you have because your car will not be able to grip. Out of pulleys and headers i would go with headers. you would probally see a better increase in power from them. and they make our cars sound Nasty!

My 2000 2.5RS had both Borla headers & Unorthodox Racing lightened & underdriven pulleys when I bought it used. I've put about 30K miles on it, and now it's at 50K. Feels fine and healthy to me. I drove a stock 2001 2.5RS, and it didn't feel noticeably slower.

Now I wish I had saved the money and spent it on lightweight stuff like CF hood, better wheels, racing seats, etc... Also, suspension mods would be nice. If you want more power, I would save a couple thousand for heads & cams (N/A) or forced induction (look for Templar's supercharger kit, due this summer if we're lucky).

That's just my opinion, the EJ25 engine doesn't respond well enough to bolt-on mods to make it worth your time & money.

Yes you will notice, but your pocket will notice too. A basic intake and Borla/Muffler are pretty cheap and don't get in the way of anything in the engine bay. MRT headers are like $1000+ and the Cobb intake will give you like maybe 5 more HP than the Ganz. For the price of those two, your almost close to getting a turbo kit. It depends if you want to pay two times as much for 10HP more. You'll get more HP taking extra weight off the car. Plus those gains aren't going to help you much off the line

 

WTF are you talking about? You DO get your stuff cheap. Do a search for MRT headers tell me the cheapest you can find. Full MRT system for $600? You got connections obviously.
