New Engine
 
Ok, so many of you know I am currently working on replacing the engine in my '07 WRX. I have had several people suggest to me, on the NASIOC site, to go ahead and put the EJ257 in. They have all told me it matches up bolt for bolt, just different pistons. I have had 2 vendors make me an offer. One offered me a 2011 EJ257 for $1600+paypal fees. He would cover shipping. I had another claim he could get me a new EJ257 for $1250 plus shipping. My question to you guys is should I go with the 257, and do you think that is a good price? Also, will the 2007 TD04 fit on a 2011 engine, if I do decide to go with that one. I already have all the parts, minus the short block.

Keep in mind that the STI blocks are slightly lower compression.

A new EJ257 for $1,250? Nope. Invoice on them is ~$1,700-1,800. Anything less and the company is losing money selling it. This is why dealership replacement shortblocks generally run around $2,300. They have to make some profit.

I would stick with an EJ255.

I also have a guy that is offering me a 2011 EJ257 for 1600 shipped. He works for Mazworx and said he can put the CP forged pistons in it and have it shipped for right at $2,000. He said they purchased to for the purpose of scanning for new billet blocks. Said it has never been used, but only has been sitting in the crate since they bought it. I think that might be a good deal.

Rods may be different too (bit stronger), I don't remember. The big difference is in the heads.

If that company bought the block from Subaru for their billet process, and it has been untouched, I would jump on the $1,600 offer. The $1,250 guy sounds a bit sketchy.

Hrm - everything will plug up from the ECU harness end? I know that even between the 06 and 07 WRX's there are different sensors. 08+ also has the plastic manifold. Ewwwwww

^Sounds like he's only replacing short block so he'll re-use heads and everything else that bolts onto the engine.

**Even if he got a full long block, it's from an STI so no composite manifold.

Jautry27 10-24-2012 10:06 AM

Ding Ding Ding! We have a winner! Yes, I am only replacing the short block. I am re-using the heads off of my WRX. I am pulling the trigger on buying that EJ257 short block today. He is also putting the forged pistons in and it is all around $2000. It is coming from Mazworx in Florida. I, for one, think it is a great deal.

That's an awful idea. You only get forged pistons if you need them. Engines with forged pistons have life expectancies of 50-60k miles when built properly (I've found out the hard way that a lot of shops should not be building motors).

Jautry27 10-24-2012 11:22 AM

Don't worry, I'm not getting them. I just found out I am only approved to get enough to cover the engine and labor. So forged pistons are out anyway. Already have all the other parts.

I've read some good stuff about it, but what do you guys think about replacing the stock oil pickup with a Covert oil pickup? Also looking at replacing the oil pump with with an upgraded 11mm. Also, plan on using my WRX injectors b/c I read they are slightly bigger than the ones on the STI. Opinions?

Jautry27 10-24-2012 07:14 PM

Also, the guy that offered the $1250 block said he worked for SOA directly. I was still very sketchy and decided to go with the one from mazworx in Florida for $1600 and no forged pistons.

[quote=jautry27;287211]i've read some good stuff about it, but what do you guys think about replacing the stock oil pickup with a covert oil pickup? [b]not a bad idea while the engine is out, cheap insurance.[/b]

also looking at replacing the oil pump with with an upgraded 11mm. [b]no real reason to, you're not adding any additional oil needs so you don't need more pump. Too much pump for not enough demand and it just starts to bypass, heating up and aerating oil unnecessarily.[/b]

also, plan on using my wrx injectors b/c i read they are slightly bigger than the ones on the sti. Opinions? [b]06+ wrx and 07+ sti injectors are identical. [/b]

Ok, so here is the final I went with on everything with the engine replacement. Got a 2011 EJ257 engine that is new in the crate. Got it from Mazworx USA. The only thing they used it for was scanning for building billet blocks. Never physically used in a car.

Covert Oil Pickup: Also got it from Mazworx USA.

Subaru OEM 11mm Oil Pump: Also from Mazworx USA.

Got all of this from the same people for just under $1900 shipped. I'd say that is one of the best $1900 I've spend in a while. Opinions?

brfatal 10-25-2012 11:53 AM

You don't need an 11mm pump. See Rcrs's post for why.

Jautry27 10-25-2012 04:20 PM

And here is the OEM TD04 Turbo I got off of NASIOC for $180 Shipped. Says it only has roughly 35K on it...
