Default 2.5 TS: timing belt, and (noob) question

Hello,
My '04 Impreza 2.5TS has 105,000 miles on it without ever having any major repairs and I'm going to bring it in to the shop for them to do the timing belt, water pump, head gaskets and spark plugs. Is there any other maintenance I should ask them to do while they have the engine out? Are there any (reasonably priced, aka under $250) mods I could ask them to install to get a little boost in performance? I looked at performance timing belts but form what I read, if I'm not modding the crap out of my engine (which I don't plan on doing) then there's no reason to get one of those. Is this correct?

I'm comfortable doing basic maintenance/mod stuff myself but I don't feel comfortable mucking around with the engine, that's why I am bringing it in.

Are there cheap mods you could do? Yes.
Will you notice any performance for under $250? No.

Sorry, should clarify - for $250 more than whatever part I'd be replacing.

Yea there's really nothing you can do at that price to get more power. Performance timing belt kits will do nothing for your car except cost you money. If it makes you feel any better, there's not much you can do at ANY price to extract significant power from an N/A EJ 4 cylinder.

You could get some Delta reground cams (you have to send them cores to work with-either your cams or a spare set), which will only run you ~$220, but installation won't be cheap at all.

If you want a boost in PERCEIVED power, you could get aftermarket headers which will do hardly anything for performance, but will give you a bit of extra growl. The shop shouldn't charge too much to install them, but don't take my word for it.

I thought headers increase HP, torque and MPG in addition to sound?

BORLA exhaust header that would fit my car - $390. I might be able to do that if I buy my wife some shoes & chocolate. Would this change much if I didn't also get a cat-back and a tune?

EL (equal length) headers can give a performance improvement...

Good headers will increase hp, tq, and mpg but unequal length headers are not good headers. They do sound amazing though. You would need no other mods with the borlas.

^^^What he said. If you really want to know what it takes to make an N/A faster, contact these guys and bring your wallet.

If you want to spend money making your car accelerate faster, go buy a faster car. You could go buy a used wrx for the same money you will spend modifying to a level that you can feel gains. The WRX will be MUCH, MUCH faster.

If you want to drive the car faster, you should tweak the handling instead as you are starting on equal footing with the faster cars. In your price range I would start with a good set of swaybars and endlinks. That or a good set of wheels and tires.

In my mind, he will always be a champeen....

You should show him that old Zero to Hero article that Subiesport did just to illustrate how costly it is to up the power of the NA motor.

Thanks for the reply. I had replied on my phone but I guess the NASIOC app ate it. I am not going for speed so much as I just like tinkering with the car to make it my own, although I would like to improve MPG since that's my only real complaint with the car. Already got summer wheels/tires that I am happy with. A WRX is in my future once I decide to get rid of this car but I generally hang on to cars for a while (105,000 on this one, 110,000 on my old Audi, 120,000 on my old Volvo). I will keep this one for at least a couple years so that's another reason why I don't want to do anything drastic or expensive.

If fuel economy is what you are after, go buy the skinniest snow tires you can find. The summer tires will destroy your gas mileage by comparison. You could also try taping most of the holes and cracks on the body to make the car more aerodynamic. Other than that, you will spend more money on mods chasing mpg than you will saving on gas. I would instead save your money and put it towards a faster, more fuel efficient car when the time comes.
