Default Spun Bearing...Rebuild.

So I got an early Christmas present on the 19th of December...Some crazy rod knock and I'm assuming its a spun bearing. Its in a local shop being disassembled at the moment.

If it is a spun bearing I have a couple of options:
1. If its salvageable...stick with the 2.0l block.
2. Swap to a 2.5l sti block and stick with the 2.0l heads.

I would like to go with the hybrid setup and I need some opinions on what else to upgrade while the engine is out, I'm thinking I might go with some Brian Crower "stage 2" camshafts (272/272) with springs/retainers for some added flow.
*I'm assuming all the stock valves weren't touched and are still ok.

Right now the car is rom raided for intake, l/w crank pulley, gt spec uel headers, catless uppipe and a catless tbe. Everything else is stock on the ej205...yes that means the mitsu td04 is still in there and I know it needs to go haha.
I'm using a ACT "modified" organic clutch disk w/ streetlite flywheel too (about a year old).

So give me some opinions!

Thanks,
dub

Go with the hybrid. My hybrid build:

New EJ257 short Block
New oil pump
New Water Pump
New timing belt
Stock STI head gaskets and bolts
Heads Reconditioned (cleaned, milled, valve job, replaced 2 valves and guides)
New Clutch
07 WRX injectors
07 VF43
Warlboro FP
Protune by Jorge

Looking back I should have gotten a larger turbo, and some cams. Definately get the heads reconditioned at least. I had 2 bent exhaust valves but car ran fine so I never knew it. Pulls nicely but runs out of steam up top. You really need some cams to let it breathe better. There are a ton of threads about hybrid builds with some good info.

yeah im probably going to go with the raw1/axis ej257 kit (comes with gaskets and water/oil pumps, belt, basically everything except the idler pulleys).
I'm definitely going to get the heads resurfaced/reconditioned, im not really looking for a valve job though ($$$, machining heads is pricy).
What cams would you go with if you decided to put some in?

if you spun a bearing your crank is either gonna need to be taken down 10 thousanths across the board, or its toast, i would go for the sti block as well, you dont even have to make it crazy to get good power. stock clutch wil still work as well

At 74K miles one of my 2.0L heads cracked.

My 257 hybrid is in the process of being assembled:

STi block/crank/rods/pistons <--- the pistons will be the weak link
11mm oil pump from '08 STI
APS 70mm CAI & TI
ARP headstuds
AP v.1
0.051" cometic gaskets
p/p/coated OE exhaust manifolds
bigger x-over pipe, coated
PWR topmount
TGV deletes
p/p/coated Blouch EvoIII16G 7cm2 <--- slightly undersized, but it's a brand new turbo and the EWG will help
Tial 38mm/Ultimate Racing EWG setup
catless Crucial Racing/STi muff stealthback
DW 650 squirters & fp
modded STi cams in 2.0L stage 2 heads -- oversized valves & seat areas, mild pnp, titanium retainers, new springs
Exedy Stage 1 clutch & LW flywheel

My tuner's conservatively estimating 300whp/330TQ.

I didn't get too into what cams I would use because money was a huge factor and I just didn't have anymore. However form the reasearch I did they seem to be the cure for the topend. People seem to like the 272/282 cams I believe. You can also use stock Sti cams but you have to plug the AVCS hole.

I got my heads done for $500.. They only milled the deck a tiny bit, and a valve job is always a good idea.

Most any cam you go with will be much better than the stock ones. I run the non-AVCS cosworth cams. Some others to look at are Kelford, GSC, Brian Crower, Crower, and Jun makes a cam for us. I've heard good results from all.

Just a note, advertised duration doesn't mean squat when comparing cams of different manufactures. Get full specs and most importantly duration at .050 lift if you want to compare cams.

BluScubi...$500 for refreshed heads!? Thats crazy its like almost $600/head to just resurface them.
kellygnsd...Good info, if I decide to get my ish throw raw performance ill be going with kelford, I have yet to talk to Ron there though so he can let me in on some options.

New option though!
-Ok...rebuilt the usdm 205 with a 257 block or...swap in a complete jdm v7?
I'm looking for reliability>performance...I'm still in school so I dont want to have my crap breaking down.
Let me know what you think.

get the 257 block for some sweet tourque. You should just sell your shell and buy a used STI. This way you wont have to worry about destroying the tranny with all the new found power.

Yeah I wish but with the Canadian dollar the way it is and used sti's up here costing around 30k I couldnt do it.

Newb question on the side...would my headers, up pipe and downpipe (for my '03 wrx) bolt up to a jdm v7 sti engine?

And I need some more opinions peeps! haha

Get a JDM long block for under $2K... swap it yourself with your own manifold.

Maybe do a TGV delete at the same time.

Done.

ImprezMeWRX.....booyaaaaa, thanks!

wobbletop...No way a long block for under 2? ...I dont have the tools to pull an engine so the shops gonna have to do it. I think id stick with a usdm block, a new complete 257 block is like 1750.

I'm going to wait to see what the shop diagnoses the engine with, It wasnt knocking for long i shut it down right away so there hopefully isnt that much damage. HOPEFULLY! haha

keep the opinions coming!

Good to know what your budget might be. I was suggested a 2.5 short block, but once you add up all the machine work and ECU tuning (and probably upgrading the trans) it was more than I wanted to spend. Going the long block way means being able to do the work myself (just bolts and wrenches, no machining) and saving tons of cash.

But I'm just rambling.

No I hear you, I'll definitely be getting a hoist and stuff so next time this happens ill be able to tackle it. Yeah all the head work is sooo pricy especially if you end up getting valves and crap...my buddy just got his cosworth heads redone and the 5 angle job alone was mucho denero.
Along with the hybrid setup, id need to go with a vf39 or bigger, new injectors, ic and a 255lph or bigger pump. im thinking a cheap jdm v7 motor would be nice, or else just sticking with the 205 .

Alright now im basically just talking to myself on this thread haha
but just to let everybody know, a couple of my buckets split in half (crazy i know!) from the adjuster screws inside...
Anyways, after replacing the buckets they're going to check for any more problems (they dont think their will be any) and then all I will need is some new camshafts.

Anybody want to recommend some aftermarket cams to go on my fairly stock ej205?

Now I dont have an excuse to go with a 2.5l or a v7 ej207 hahah

If you do cams, I'd recommend the Cosworth 275 duration 10.2mm lift cams,....good stuff : )
You would really benefit from porting of the heads as well, that's how you will get the most benefiit from the cams / valves / valvetrain. Plus, if properly ported it will correct any inconsistencies in flow.
That's how I found out my heads weren't flowing properly to one cyl.
