I honestly cannot understand what you are asking at all. Can you please rephrase and retype your question in a way that someone can understand?

Are you in a different country and trying to translate?

my bad i got carry away i want to go turbo on my car and the motor that i got in it right now is ej251 im doin the heads right now but i wanted to know if i can put the wrx heads wich they r 2.0 on the ej251

Smaller heads (smaller than 2.5L heads) on a 2.5L motor will result in High compression which is not desirable for turbo applications.

I would suggest searching google like this:

From what I have read, you are going to need a heck of a lot more parts than just the turbo...

I am sure someone else a little more knowledgeable will chime in. If you want to be somewhat different you can look at supercharging like a few other members on here have done.

thanks yea i know im going to need more parts the bottom subframe and the header up pipe down pipe umm injectores computer and im doing front mount not top mount but i just want to built a good motor cuz any one can go and buy a motor i just want to build just like the hondas u can make a poor mans type r or u can put k20 and k24 parts together but i want to learn a lil more with the subarus so i can go the right way with the turbo u know and thanks

You can never compare a B-Series or K-Series motor to any EJ-Series motor.

That's comparing Apples to Jagermeister..

I love seeing custom turbo setups but your barking up the wrong tree.

Even after you source parts and fittings and odds and ends.. You will be dealing with a short block that has no reinforcement to handle boost. Sure you can run 4 - 8 psi but whats the point in spending dollar after dollar for something that will let go at any unknown point.

Bring the compression down then tuning with various standalone systems or piggy back a/f controllers is sketchy stuff if you are unaware.

Buying a complete swap or at least a WRX EJ205 engine + wiring harness + ecu + turbo subframe will save you months of headaches.

Starting with a good platform that can handle boost and a computer system that allows for EEPROM flashing is worth more then any piggyback system can give you.

Your embarking on a long journey that you may not be ready for.

Although Subarus are LEGO and are constantly being preached and compared to Honda.. They simply are not as easy to .. errrrr.. no wait. they just are not cost effective as a Honda.

Chucks right, your engine is shite for boosting (porcelain pistons, too high comp. ratio, etc)
Buy a wrecked Wrx, swap the front; OR source a ej222 block have it refreshed, and then you can start planning your build. The heads you have flow okay, but Wrx heads are FAR superior.


Also, Chuck, the Wrx subframe is wider and requires control arms, steering rack, and a few other bits. I'm not sure a turbo legacy xmember would be a direct bolt on either, though.
