What do you think about this ph1 EJ25 Crank?

Is it toast? It has only been sitting in my shed for 1.5 years. I think maybe it's just surface rust.

If its been sitting on its side like that for 1.5 years its probably warped

WTF??


Since forged steel warps so easily... :roll:

Not worth it.... Buy a good used one for $60 and call it a day...

Even though its surface rust, you are going to have to have that ground which is going to cost a whole bunch.... Then you are going to need oversized bearings....

Its really not worth the headache....

I polished it up and it's smmmmmoooothve. Super-smove.

I doubt it's warped and I know this one only has about 10,000K on it.

But I did run a piston with a broken side skirt on it for a few rallies.....

The diameters are 2.263 and 1.891.

the shorter the crankshaft the less chance it has of being warped. but it could happen. not probable but it is toally possible. kinda depends how its been sitting. i would make a chair or something out of it now( who doesnt like car art). you can find cranks all over the place.

It only needs to be bent by a few thousandths of an inch to be useless. A bent crank will chew through bearings like a fat chick after 2 days of dieting.

WTF +1.

I didn't know forged steel, sitting on in a shed at any 'low' fixed temp will 'warp'. Please elaborate. It doesn't take much to bend one, and yes they're ruin bearings stat.

You do realize that crankshafts from subaru are stored in boxes in the same position right?

I think maybe it's more of a problem with longer V8 cranks sitting for decades..

Storing it vertical would be MUCH worse.

Apparently solids can flow. I was in Europe last year and saw first hand how old glass windows are thicker at the bottom. Freaky.

Anyway, I am probably the cheapest one here on the forum (even though I am professionally employed :) so this crank is getting thrown in a PH1 NA 2.2 block. He he. Unless someone can give me a EJ22T block for 100 bux? Anyone?

I know dr soul has some experience with building the 2.2 stroker - and you probably don't like this approach - but can anyone guess how much ommph the NA2.2 block is good for when it has appropriate psitons. It's open deck but there is a lot of metal there.

I know that I an not interested in EVER spending more than 300$ on a turbo. (except for the 400$ I gave m.monson) so I'm thinking VF39, NA block, stroker, 17 PSI.

I'm a total short term fun / research / cheap personality. A vendor's nightmare :)

Just out of curiosity, why do you have to use the 25 rods in the stroker? Can't you use the 22 rods with an appropriately dimensioned piston?

Yah, no shit it will eat bearings...but since you are the first person to ever mention something like this in the many years that I have been working on cars...I call BS...


If you can get me some concrete evidence (as in not what you read in Superstreet or Ricer Magazine) I would be more inclined to believe this

Glass isnt a solid, its a super cooled liquid.

This is true.

If I remember correctly though, solids *can* flow as well to some extent...

i like how you call BS, you werent there nor did you see how this crank has been stored....Chances are the crank is fine. But it is possible. im not trying to be a dick, but if you can venture out of one track thinkn you might see someone elses point of view.

all forged steel is generally the same this HAS happend before maybe not to you, and maybe not too much in this forum. But i have seen and personally mesured crankshafts that are warped, out of spec. Due to the way they were stored.

In service manuals they wouldnt put specs for us to go by if it hasnt happend before

Well, you succeeded in coming off as a dick...I still call BS, and I am done posting on this thread before it gets too out of hand and gets away from its original objective.

It's mr soul, although I am pursing my phd in stoker building...

With a good tune, you should have lots of fun. That block is no better or worse than open deck EJ20's and there are lots of WRX owners pushing that boost level in stock blocks. You'll have the benefit of forged pistons for a little more strength too. Knock detection/contorl like a safeguard unit would be money well spent if you are into security.

The reason you can't use the 22 rods is they have the wrong rod journal size, 52 mm instead of the 48 mm you need. You need phase 1, 2.5 crank and rods with the off the shelf wiseco's for this build.

Have fun.... :D
