Ok so l have a 97 subaru impreza 4 speed auto stock and l was wondering if l could put one of the new 230 hp turco charged engines in my car and if so what is needed

no

Yes it could be done, but it would not work well & it would cost a fortune.
1. engine is way expensive
2. new wiring harness would be required
3. the wrx has a much stiffer frame-your is would not handle well
4. u would spend as much as buying a wrx & u would still have an impreza.

You've got some good choices around. Mazda 3 is coming out with a 250HP speed3 in 2007 faster than the wrx but slower than the sti (currently there is not much in the class of the sti)

Yes, u absolutely can swap the turbo engine into ur 97 impreza. Now there might be some slight fabrication & u will need to purchase new motor mounts to do this but it is all very capable of doing. Depending on which engine u want to swap (EJ20t or EJ25) u might need different mounts. (Im not real big Subie guy but l know enough)

My advice to u would be to go around to Subaru forums & ask some questions. There r plenty of die hard Subie fans that will give u all the information u need to make ur swap go as smooth as possible. l wish u best of luck on ur swap!

It could be to easily. Just make sure that you find an EJ20 (2 Litre) from ebay or somewhere else. The new WRX and STi is have an EJ25 (2.5 Litre) You can find info at NASIOC (North American Subaru Impreza Owners Club) forums.

l have an 04 STi that l love. You can check it out on my website supercars.com

Yes u can.

The ej20 out of a wrx is a good choice, if u have a professional shop do it it cost from $5k for just the engine to $8-9k for the whole drivetrain (engine, tranny, & rear end, even the dash can be swapped with work). Also if pro. done, is 50 state smog legal as well.

Mechanically the swap is not too bad, is the wiring thats a pain. Some places change the whole thing, some merge the two. Both r realiable.

Still possible is the ej257 swap, but the engine swap alone is about $8-9k. However u DO get 300chp. The whole drivetrain is about $12k 14k. A lot of money, but you'd essentially have a STi with a GC8 body.

As far as a wrx being a tighter car, that can be fixed, between a nice strut spring combo (or coilovers, thicker swaybars, & a rear strut bar, & maybe a few more odds & ends, you'd be set.
