I have a 1500 engine in my car.  My problem is that i accelerates very slow.  what can I do to increase my acceleration?  Do I  need some form of forced induction to achieve that or what?  I dont have the money to purchase a bigger engine or to buy another car now.  so please help me.  Its kind of lazy over hills too.

Easiest way is to sell it and buy a 2.0R or a WRX. You could try swapping-in an NA 2.0 or 2.5 but you would need the ECU from the donor car and probably the entire engine wire loom just to be safe.

Listen, I know someone with an Impreza that was turboed, it was working quite well too, but he had an accident front damage. I spoke to him and he is not adverse to trading with you if you want pm me and I can put you on to him.
Maybe you can give him your car and repair his and keep it....just a thought.

kenley, you haven't  said if its a matic or standard ?, however  i have that same problem especially in the mornings and sometimes during the days with my 2.0L standard shift legacy. even after a decatting and fitting a K&N drop in filter, the result were never that noticeable, there has always been a flat spot while accelerating that has always been of concern to me, i have however acquired certain techniques that have allowed some level of pick up in acceleration, that sometimes makes others wonder if  my car is somewhat modified, The Lagacy also has a very heavy body and unless your RPMs are up there on the move off or even while ur  rolling then u may tend to feel the lag.. Try accelerating gradually on the move off  instead of stepping in the accelerator pedal as hard as you may be doing now and see what happens. 2 thumbs up

I got the same problem with my 2.0R, anything under 3000rpm there is a lag of some sort, but once your over that rpm, there's power with no lag. but the lag doesn't really bother me. So all i do to avoid the lag is let it roll out til i get to 3000rpm, and once over that i am good dont select gears (sports gear box), until i am at 5000 - 7000 rpm and i am good where power is concern.

I had a 1600 Impreza. I loved it...was quite a solid and reliable car but I know exactly how you're feeling.

...Try accelerating gradually on the move off  instead of stepping in the accelerator pedal as hard as you may be doing now and see what happens. 2 thumbs up

I agree with buRRRble-B4...instead of flooring the pedal from a stand-still, rolling out was a better option. Re hills, once you have the momentum going it wasn't so bad. Enjoy the reliability of your Subbie 2 thumbs up

Im  still a bit concerned about this non responsive gas pedal on the moving off, and even when ur up in RPMs and you press it theres not always the response you expect, im thinking that there must be some sensors somewhere that needs cleaning....what about the sensors on the trottle body or whatever its called?....cho mi gone search fo a remedy yerr....

Well, did a  one search and found the following on Legacy owners association site..


:-2.5 NA. Do underdrive pulleys work on these cars? I've read ya and nay. Will it hurt my alternator life?

Any simple mods recommended to squeeze even a little more hp out. Not looking to make a race car. I like getting 30 MPG's on 87 oct.

IMHO I would not use an under drive pulley, I would just use a lightened one, the stocker is around 5 lbs the aftermarket ones are around 1lb, that in its self should be a noticeable difference considering the amount of rotational mass you are freeing up. im sure the gains are not as high as any web page says they are, and to my knowledge no one has a baseline of a before and after with just a pulley, so to answer your question if its going to "gain" hp.. I do not know but you will feel a little difference from what i have heard, but its not going to be like punch you in the face throw you over the shoulder run down the street screaming power

theres not much for power, search around im sure you will find all the info you need on this site..


also how are you getting 30mpg?

Go for light weight pulley. really improves the performance.

or get throttle controller to change throttle response on your NA.

I found marginal difference with a lightened pulley. Seems to have more improvement with auto trans. Every bit helps.

Yes I have a Perrin lightweight crank pulley (regular not underdrive) and got an automatic. Desperately needed a little more punch and made a huge improvement going up hills or even cruising at high speeds on the freeway. I highly recommend it.

DJ, you mentioned in another thread that the lightweight pulley caused your idle speed to change. Is a tune necessary after installation?

My 2 cents: as a standalone mod, NA or Turbo or whatever, a LWCP will have marginal/negligible affects on performance. Will the engine be slightly more responsive? Sure. But at what cost? Probably a very slight bit of overall smoothness as the heavier stocker (from a ratational mass perspective) has a flywheel effect.

Similar story for underddrive. Yes, you'll get slightly better response overall but all your accessories will be underdriven and output less (e.g., alternator, pumps, etc.) which isn't necessarilly an issue at speed. At idle, perhaps slightly.

Personally, I don't see these as value mods.

Well, did a  one search and found the following on Legacy owners association site..


:-2.5 NA. Do underdrive pulleys work on these cars? I've read ya and nay. Will it hurt my alternator life?

Any simple mods recommended to squeeze even a little more hp out. Not looking to make a race car. I like getting 30 MPG's on 87 oct.

IMHO I would not use an under drive pulley, I would just use a lightened one, the stocker is around 5 lbs the aftermarket ones are around 1lb, that in its self should be a noticeable difference considering the amount of rotational mass you are freeing up. im sure the gains are not as high as any web page says they are, and to my knowledge no one has a baseline of a before and after with just a pulley, so to answer your question if its going to "gain" hp.. I do not know but you will feel a little difference from what i have heard, but its not going to be like punch you in the face throw you over the shoulder run down the street screaming power

theres not much for power, search around im sure you will find all the info you need on this site..


also how are you getting 30mpg?

you can get 30mpg if you drive all highway with the 2.5i

Go for light weight pulley. really improves the performance.

or get throttle controller to change throttle response on your NA.

No harmonic balancer concerns?

I found marginal difference with a lightened pulley. Seems to have more improvement with auto trans. Every bit helps.

i don't believe there is due to the boxer configuration, several people have had the LWCP without any issues for many years now

Yes I have a Perrin lightweight crank pulley (regular not underdrive) and got an automatic. Desperately needed a little more punch and made a huge improvement going up hills or even cruising at high speeds on the freeway. I highly recommend it.

DJ, you mentioned in another thread that the lightweight pulley caused your idle speed to change. Is a tune necessary after installation?

My 2 cents: as a standalone mod, NA or Turbo or whatever, a LWCP will have marginal/negligible affects on performance. Will the engine be slightly more responsive? Sure. But at what cost? Probably a very slight bit of overall smoothness as the heavier stocker (from a ratational mass perspective) has a flywheel effect.

Similar story for underddrive. Yes, you'll get slightly better response overall but all your accessories will be underdriven and output less (e.g., alternator, pumps, etc.) which isn't necessarilly an issue at speed. At idle, perhaps slightly.

Personally, I don't see these as value mods.

I have a friend with a 1994 Subaru impreza n/a. When him drive that car u would believe him have a little boost.

I understand the feeling; still I think u should leave the n/a car alone and if and when u can afford it buy a STi.

Then u might still want to go faster and the STi would be both a good practice and starting point.

I have been wanting over 400whp but the funds just not running.
