Question WRX spun a rod, ADVICE NEEDED. looking at ej22t block?

i got a 02 wrx and was driving to work when i got off the highway it died at the light. started her back up heard scraping and pulled her n the median (50feet from light) towed ( on flatbed trailer )back to the house and she's knocking like a hammer on a trashcan. i JUST broke-in my new deadbolt td04 (818.17 miles) when this happened. in looking at engines i don't have the money for a 2.5 so don't open that hood. i bought it used w/128k and am still paying on it. i want the car so fixing it is on the list 2nd to school.

Specs: still paying on it ( yes it sucks )
  • 2002 wrx 129k
  • stage 1 clutch and lightened flywheel ( just under 1k miles on them )
  • greddy dpb exhaust
  • p&p deadbolt TD04 (818 miles on it, seen full throttle twice in second gear)
  • K&N

been researching for a week and like the idea of a ej22t short block in its place if possible. new engine or rebuild are about the same in cost it seems. it'll be a while before i get her running but i need to figure out THE PLAN. i have a few questions though. open to suggestions also.

  1. will the ej22t w/ wrx heads have a low enogh compression (8 to 1 ish) without replacing the pistons?
  2. will stock wrx fuel system work w/ a 2.2 platform?
  3. could i use my td04 with this setup and perform well for a dailydriver?
  4. 4. $1800 for a ej22t short block about right? (Short block, legacy, w/turbo - 2.2l, legacy - 2.2L, LEGACY $1,841.46 @ www.1stsubaruparts.com

I'll be doing the work w/ my dad ( 30yr engine guru ) limited on money and driving a 230k backup ZJ. inbetween a knock and a hard place right now. Help or advice will be greatly appreciated. thanks

did you even look up the price for a 2.5 turbo shortblock? Because it's like $1750. And you have a better design, better cooling and more displacement that the 2.2.

As for compatibility, you take your heads, intake manifold, sensors, and wiring harness, and attach them to the block with 2.5t headgaskets. So everything works. You just have to plug the crankcase breather.

i would jut get another ej205 block and not use mobil 1 synthetic oil.

ej22ts are cool but over kill, especially for a pea shooter like the t0d4

the reason i can't do the 2.5 is that i don't have money for the injectors, fuel pump, and bigger turbo that it'll need. plus the 5 speed won't like those numbers anyways. thinking a 22t could safely hold higher boost / 17-19psi /. while behaving close to stock if around 15psi

What is the psi range of the td04// or can it power a 2.2 in the first place? i haven't seen or heard of this combo anywhere. if not then i guess a 2.0 is in order.

AGREED WITH THIS POSTER!!! ^^^^^^^


I know several people pushing stock EJ205 engines well beyond 320whp on daily driver tunes...

why not find a good used ej205 shortblock for cheap and swap it right in for less than $1000 total?????

Run any SL rated oil (most of the diesel oils are still SL rated....) and you will good for a LONG time....

Stay away from Mobil 1 crapola.....


GOOD LUCK!

easiest thing I would think also would be another ej205, especially if you aren't really planning on pushing things power-wise (some have gone to around 400whp on the ej205 without problems..... depends on setup).

As mentioned, stay away from Mobil one synthetic the dealers love to dish out.. It's horrible stuff that vanishes really quickly.

i guess ej205 would do. it be a turn key app right? no real change at all right. this will be my first rebuild/replace so i'm learning as i go.

trying to find a block without much luck. anyone have a good block lying around that i can $uy in NC? with my time frame and money simple is probably better.

yup, the EJ205 will drop right in. Straight swap over and carry on. Why not just get a new ej205 if possible from a dealer or subaruparts or whoever? That way you know you have the peace of mind of knowing the history of the shortblock at least.

if you're putting in another 205, make sure it's used. Buying that pile of crap shortblock new is a waste of money.

And you'll be fine running the stock turbo and injectors and stuff on the 2.5. Sure it's not ideal but it will work.

so i can(not ideal) run my stuff on a 2.5 block. granted i get it tuned. in that case i found this ( http://www.cgperformance.com/subaru_block.htm ) they have 2.5 closed deck block for $699. i would just need to find a good price on internals--( is this realistic under $2000? total)

thanks for the info guys i still got a bunch to learn in these next few months.

A vendor in the classifieds has a forged set for $800. Rings, bearings, forged pistons (mahle?), and forged rods. Someone else (gruppe-s) sells stock STI internals for $600 IIRC.

yup..bolt-in and go.

i was planning on doing some retarded big whp build up then i realized a big16g on a 2.0 liter would probably be enough to make me happy and still get me from point a to b so i decided to K.I.S.S it and get a streetbike

But remember, you need to ASSEMBLE the crank, rods, install pistons..... as well.
