Hi Eeveryone,

Rebuilding my 2.0 from my 2004, does this sound like a decent combo for a reliable 300whp - 350whp motor?

Thanks!

the wrx rods are the same as the sti. don't bother buying sti rods to try to upgrade.
that is a fine setup, all you really need is forged piston for the motor for that power.

you will be fine, im pretty sure you can go 350whp on a stock block with somewhat low miles and be fine all day. pistons are all you need until you start talking 400whp+

Should I just stick with a new OEM shortblock then and skip the hassle of a built motor?

Nope...at a minimum you should do forged pistons if you plan on going with a bigger turbo at all.

From experience I can tell you that I just rebuilt my stock 2.0L bottom end, using STI rods, and Mahley 93mm bore pistons. Also had the entire rotating assembly balanced. Im running a 18g turbo and my bottom end should be able to take whatever I can throw at it.

This maybe true for the 2.5L WRX blocks but it's not true for the 2L blocks. 2L WRX rods are very weak.

Good to know, as I have an 18G set up too.

What bearings did you end up using?

Also, do I have to worry about the gunk in my block from spinning a bearing or will the hot tank process flush all of this out?

The hot tank process should take care of any gunk, I dont know that for a fact though. When my machine work was done the block halves were very clean from the hot tank process. Sorry I forgot to add that the bearings I used were ACL race series both rod and mains.
