Default 02 WRX ej205

So I'm planning on doing a EJ205 build (well not planning but already in the mix) since the stock block is only rated for 350whp I was wonder if what I heard was true. That the pistons and rods are the first to go (along with bearings) and that the valve train is pretty good to go. I'm trying right now for a vf48 build and I want to see over 350 as right now I am only satisfied with 330(to be safe) what all do I have to worry about when it comes to the EJ205 and power over 350whp. I am also in the process of removing the motor so I can start working on the internals.

Thank you

There is no right answer to this. Try it and see. Any vf series turbo will BARELY get you past the 300whp mark. Shoot for at least a 20g.

Check proven power section and see what's up.

Well right now I'm sitting at 299awhp with a vf30. So with a new fuel rails, TGV deletes and the vf48, myself and the guys at national speed have predicted about 350-360

You can predict 500+ doesn't mean you are right. Don't you think if you could get 350 out of a vf series turbo they would be more expensive used and harder to find?

there is virtually no difference in a vf48 vs a vf39...the predicted numbers are in line with a high reading dynojet on E85 on a good tune and supporting mods.
