Default Need Some Advice on Just bought a BLOCK and need some advice ....2.0,or 2.2???

Ok i need some advice from some of you knowledable subaru guys...
Ok i just bought a stock wrx block and want to build off of it.. I dont know what to do as far as displacement... i dont know if i should build a 2.0,or 2.2..
My goal is 11.5's and i will be using an APS SR-50 to get me there.. I do not want to spray on it but will probably be using water injection most likely....
Do you think i should stay with the 2.0 and build that or go with the 2.2.. I most likely will be running JUN cams, ported out heads,valves,springs,retainers, ect....
I am going to have it sleeved for sure but dont know which one to go with.. Also i dont know if i should stroke it or stay with stock stroke...
I want it to be able to handle really high boost, with no proublems..
Let me know some opinions on this subject i would really appreciate any info you can give me.... thanks, ERIC

SR/50 is a good turbo that will make power. On stock displacement and stock compression i think this turbo is the wrong selection. I would look to do at least a 2.2 and up the compression. That should decrease the lag on the SR50.

Talk to Darton Sleeves. They make a very nice sleeve for the EJ series engine. But I think the minimum bore size they offer is 97 mm, But you can bore up to 105 mm with those sleeves. I'm pretty sure those are the correct #s. I just checked a few weeks ago.

Look for using a Cometic head gasket and ARPs or some other head stud. Although the Subaru Head bolts appear to pretty strong, I would hesitate to use them in high boost situations.

I would look to use Ross Pistons from Magnus or CP Pistons from Ron at Axis. Those seem to have netted nice results. As far as rods are considered. Go Big. Pauter or Carillo are both very good choices and are very strong.

I would get a 2.5 shortblock.

Search the forum. I was reading that you can get a new one for $1500.

Stroking and/or boring the 2.0 will cost some $$.

The cheapest reliable way to power is more displacement.

word, go to 2.5L its just easier and cheaper. more power from the displacement and i'd believe less lag and larger turbo possibilities. xs engineering 500 or whatever you can get your hands on...i guess sr50 is the same basically, its all relative. when i have the funds 2.5 is hat will be in my piece of junk

buying a 2.5 is almost definitely cheaper and better than making a 2.5. Also the only thing you do is buy it and bolt it up...dont have to worry about all the fabrication and problems/gremlins that will pop up.

If you get the 2.2L block then you would probably need to replace the pistons to up the comp ratio,( if i remember right the combo with the wrx heads gives a low ratio of about 7.4:1 maybe lower) and while you're there change the rods too..... the block can handle about 20psi in stock form and definately more with upgraded internals. Where as the 2.5L bolts to the wrx heads with a slightly higher comp ratio (maybe 8.7:1) which would be good even without a lot of boost, but if you're planning on lots of boost you'd definatley need to change the pistons on that to lower the comp ratio but the actual block is not as strong as the 2.2L block coz its semi closed and the 2.2 has a closed deck, So it all depends on what you're trying to accomplish. Hope this helps

Assume you wanted a high rev'ing monster.

Don't stroke it, if anything have the rods/pistons designed to offset the wrist pin so that you slow the piston DOWN.

I'd honestly take that shortblock to magnus, spend the 3k for their stage 3 sleeved block, and enjoy.

It'll be assembled professionally and it be ready to go.

IMO, I am a sucker for torque... so >I< say stroke it..

But if you still want something that you can beat to snot, Marco and co has shown some pretty compelling work.

For everyone out there thinking he's buliding a 2.2 - it looks like he actually has a stock EJ205, and he wants to build it out. I know that lots of you will have spotted this, but he's not talking an EJ22. If you want to build this and run 11's sans spray, I'd definitely send it off to someone who knows what they're doing to build up the block. It seems Magnus is a great choice.

Of course, for that price ($3K), you can also just about buy an EJ207 type RA longblock, sell the 205 shortblock, sell the 207 long-block components you don't want (up, turbo, injectors, TMIC, etc.), buy a JDM ECU and you'll have much better cams, AVCS, forged internals, a good port job that handles lots of air and a redline of at least 8500. You'll spend a bunch less than you would on a magnus/self build out and be able to make serious power with at least some low-end torque for getting to and from the track. Let's see:

Buy (I'll use expensive prices):
Sti type RA longblock: $4000
Type RA ECU: $600


Sell (I'll use cheap prices, and not count your current parts):
WRX shortblock: $500
Sti injectors: $200
Sti TMIC: $300
Sti RA turbo: $300

So, not counting selling your current parts, you'd be out $3300 using the highest and lowest estimates, respectively, I could figure. You'd have the block, heads, cams, AVCS, forged internals, etc.

Or, you could spend $3000 for a Magnus workup, $1000+ for cams, lifters, etc, big money on head work, and still not have as much core to sell off. I'm not saying option two wouldn't be better in many aspects, but option 1 looks pretty darn attractive.

I'm not sure how much axis would charge for a short block, but they are worth calling for the head work.

blocks are priced for everyone...

from 1325-5000 $ just depends what you want to do and how much money you want to spend.
