Default 2.2 Legacy block into a 2002 WRX

I have a 2002 WRX and am going to do some engine work on it. Will a 2.2 litre 1994 Legacy Turbo AWD block be a direct replacement for my stock block? If it is then I am going to look into them, since it will be cheaper to bore a 2.2 to 2.5 than it would to take a 2.0 to 2.5.

The 2.2 legacy block is the strongest block subaru made. You dont need to bore it anymore its already a 2.0 bored to 2.2. You can have it worked so it uses a phase 2 ej25 crank and then get yourself a 2.4. But realy the block is as strong as you will ever need. check out this thread. I have posted links too all the 2.2 leg block info you will ever need.

Ok, that helps a lot. When I get it built should I have it sleeved, or is it strong enough as is?

I saw that Axis has a 2.35 that looks fairly decent. There is a place in town that when all is done it would cost me about 3500 to have my stock 2.0 bored and sleeved to a 2.5 (I think, I need to re-add it). I might look into the Axis block.

Will my ej20 heads bolt directly up to the ej22?

Ya, the wrx heads will bolt up... you dont need to get this block sleved check out this thread.
http://forums.nasioc.com/forums/show...ght=ej22T+ej22 The C/R ratio and what gasket to use should be covered in one of the other threads in my first link.

How much power do you want? Say above 400 you might want to pick up a block from axis, cobb, or ispeed... But the 2.2 is more then enough for most set ups.

The 2.2 is an awesome case. Here are some pics I took comparing the stock sleeve liners of a JDM 2.0 STi, a US legacy turbo, and a US 2.5 STi

Yea, I am looking into Axis blocks now. It would be worth my time and money to go with one of theirs.


I sent you a PM Mike.


Yea, the 2.5 looks dwarfed next to the 2.2

How much power are you looking to make, and how much do you want to spend?

I am wanting to make around 400-450 at the wheels. I am looking at getting the Stage 4 from Axis, so around 3500 on the block.

Mike, I sent you another PM last night, did you get it?

Cool, good luck. Dont forget the heads, and other goodies to put that block to use. Have you figured out how much this will all cost yet?

I am looking into getting valves, porting, and cams right now. And I have figured it to cost a lot, but I would rather spend a little extra now and have a really well built engine, than to have to have it done when it blows up.
