Talking Video: Subaru Block Supports allow 40-50 psi

Originally posted in "news" section b/c this is news for the community, but the thread was locked and I was told to post here. So I apologize for the double post


I was at S&R Performance last week for my buddy's STi build and they talked to me about this new product they are developing. Called "Subaru Block Supports", this is a piece that goes between the head and block and fixes the typical block cracking between coolant and cylinder fixing the flaw in both 2.0 and 2.5 blocks. I shot a video for them as seen below:


Here is the official S&R post on their blog--> http://www.sandrperformance.com/SR-P...type_b_15.html

What myself and S&R Performance is interested in knowing is what the Subaru community thinks about this idea. This product is currently in developmental phase and official release is unknown. Thank you Nasioc community from SubyPAL and S&R Performance!


Here's a video of the CNC process too

Cost? Could we order case halves that have been machined and come with the supports? Sounds like a good idea.

um, so what's different about this than what Outback (now Outfront...many others have done it as well) has done for years...which have been proven to still split sleeves...?

I will say that you seem to remove less block material than them however.

In the Honda world people with block guard still break their sleeves so I guess the best bet would be some sleeves (Darton, AEBS etc...) and then if you want you could use a block guard.

Best alternative to a sleeve would probably trying to press a pin into the bolt relieve groove. It would pretty much be a permanent thing since you should have fun getting the case halves apart if anything ever failed or needed a rebuild.

my only fear with that would be the differences in thermal expansion of the materials. It may actually cause more stress on that section of the liner.

How would you test it? Since a well tuned engine "can" survive on the stock sleeves at 500whp, what would the test be? Run more power? I'm assuming you're not trying to hold back on that now.

Beat the crap out of it and see if it cracks or shows signs of cracks. Plenty of overbored blocks have signs of multiple small cracks before they ultimately fail. I have a few pics but I need to dig them up.

these guys are no joke. This shop is where i have had the work and tuning done to my subaru in tampa, fl. I've known the owner for many years now in the Mitsubishi community when I was a DSM builder and tuner, and he has been a bigger influence in the Subaru community around here. If they can tune my car to make 340 AWHP at 20psi on a stock EJ205 motor with 565cc injectors on pump gas, I know they can build one HELL of an engine. S&R Performance is awesome!

thanks, man. This is something that we're putting a lot of work into. We're putting together a block now that will be going into an STi that makes over 650whp. We're going to put it to the test.

We're trying something different, we do not know of anyone that has done this with this kind of detail or approach. We're confident that it will work out very well.

Doesnt that dune buggy place do someting similar but with a closed deck application? They are on here because they use Subaru applications in the buggys.

Found it. http://www.outfrontmotorsports.com/engine_blocks.htm

Care to ellaborate on the claim/differences?
What's different about the approach aside from what seems to be multiple billet sections per side?
What is more 'detailed'?...extremely vague claim to my ears.

Same place I linked to before. I've also stumbled upon Aussie and European sites where they do the same thing.


Man, this makes me want to get back on TampaRacing...

I agree. S&R has a great reputation for being the best shop in Tampa for Subaru oriented performance. If anyone can do it, they can. S&R for the win!!!

the block guard alone is not enough to push 50psi into those cylinders. sleeves and this with be almost bulletproof. sleeve, cement and block guard would be overkill.... lol

Default Here are some pics, fresh out of the CNC.....

So we just pulled our our test block and did the first round of fitment and install test and throw her in for resurfacing.









remember, this is all testing. We're trying this out to see how well it works. No one is claiming that it's a replacement to Sleeving a block but it could be another option that will cost less and should hold up well. We'll be putting our money where I mouth is with putting this into a STi that will be runs over 30psi. Our R&D will show us what this will do and we will handle, market and sell them accordingly as we work with it.

For now, we're excited about the process and we're really looking forward to the testing.
