Hi guys does anyone no if a sti engine will fit and run in a wrx 2001 model without any modifications and will the injectors be the same size or are the sti ones bigger

Its possible and has been done. Try doing a search.

 

Just get the best out of the WRX engine you have....much cheaper

 

The wrx engine has seized and i can get a sti one for the same money as a wrx engine

Are you buying a full engine or just the short block?

Although you can probably use the short block, the heads on the STI are different (AVCS - some variable cam timing thingy).

The STI has 505cc/min injectors as well (aka "STI pinks"), where as your WRX will have 380cc/min injectors.

You probably need a remap as well, especially if you're going to start changing injectors etc.

 

What year is the STI motor, if it's newage then it will be easier, if not you are on your own...

STI doesn't have EGT like WRX on a new-age, at the least you may need the ecu and a re-map to get it upand running.

Good luck !

 

Thanks for the replies guys its a 2001 wrx and the engine is a version 7 sti with avcs
