How to Build the Subaru FA Engine for BIG Power!

[@davidf7rt]

Thanks to Mike now i want to WPC treat even the spoons and forks of my home, the floor, the whole house, my wife, my dog, my friends... Everything now needs to be WPC treated and cryogenically treated 😂😂 ❤❤❤❤

[@ricepony33]

Do not cryo treat your dog, very stiff.

I love that in the same video he talks about contrasting crystalline grain structure so intelligently and then some how says things like “makes ej’s go bye-bye” and “dead nuts balance” without losing any credibility. Fantastic video!

@@motoiq well then you're well aware of cryogenic treatments and martensitic start and finish temps but - where do you get the info on what alloys are used in these engines to even .. explain to me why you would cryo a tempered steel (nitrided?) crankshaft without a salt or lead bath austemper? Is that 5% of martensite going to matter on these alloys or is that literally just marketing? I don't know if I have to say this or not but I obviously respect the hell out of ya man we obviously both have similar interests and whatnot - I'm not.. necessarily well okay I know it sounds like it over text but I really am not like arguing or trying to. Honestly I enjoy your videos but I couldn't get past the "we cryo our cranks" just because to me personally? With my knowledge which is not absolute (I'm sure we both forget stuff although everything I heard you say was correct but I did not finish the video because of the cryo deal). Moto, I owe you an apology for not finishing the video because, well obviously being a doctor on the internet puts me in a unique position henceforth my name. I just fail to understand the purpose behind cryo treatment post heat treatment, unless it's mainly a marketing deal. We don't know each other, but I absolutely cannot stand "marketing" or "advertising" or "corporate America" to an extent that you would not believe, so seeing someone that I respect start saying oh ya well soak your metal in ln2 for 500$ when I.. work in said corporate America and as a hobby I make high carbide PM kitchen knives for professional chefs, so obviously I know what alloys benefit from cryogenic treatments and which do not. But I have no idea how you are identifying these alloys being used because I personally have xrf/XRD and it's not enough for that purpose. GC-MS-MS? That would not be cheap but I can't rule it out. Also I'm incredibly sorry for freaking saying the school thing. That was a bit out of line. I hate people who go around with where they went to school. But since I did and I kinda know what I know, I am sorry but I did have to ask questions about it. I suppose I still do have questions about it. I don't deal in the engine steels or anything like that nor do I know where to find out what is what. I'm in the austenitic/duplex alloy department for work, henceforth my fun hobby where I get to play with ZTA ceramics and metals. Not that we'd want to cause of asperities grain growth yada yada but - is there a way to find out what alloy is being used so it can be re-heat treated or suchlike? I could say that would make a difference a little bit more than say just chilling to 196c. I work for US steel automotive research as a metallurgist fyi. I thought I posted that.

[@motoiq]

@@KZbin_Scientist Alloys for the pistons, cranks, and rods are known from the manufacturers. 4340 is pretty common for rods and cranks, the crank is not SAE 4340 but the JIS more or less equivalent, I forget the number. The crank is nitrated. The pistons are 2618 which is pretty common for American forged pistons. 4032 used to be popular but with improvements in piston design has fallen out of favor lately. As for the carpenter alloy, it was in the valve manufacturer info, I forgot which carpenter alloy numbers were used but since I was on a one-take roll when shooting the video I just kept going to make post-production easier plus I didn't think our audience would care that much. Cryo is more wear-resistant on an engine's ferrous rubbing surfaces. I have seen this in engines many times. It is also well documented in tool steels. Personally, I don't think it has much value in nonferrous metals except maybe stress relief. Look up some of the white papers on google about cryo. There are many interesting ones. I started using it many years ago and it seems to have worthwhile results in our high-power engines. In one series we do engines for, our engines go about 2x longer in between refreshes compared to our competitors. In our race engines, the rings have very little wear even after a season of use. The gaps stay close to the same and the second compression ring isn't even fully seated across the face! Cryoing eliminated valve spring failure for us, even with aggressive roller cams. One of my rifles went from one MOA accuracy to an astounding 0.25 MOA! It was also less sensitive to ammo quality, shooting no worse than 1.5 MOA even with cheap ammo on a bad day. Good cryotreating isn't so much dipping in LN2 but slowly reducing the temp to LN2 temp, then slowly increasing the temp to close to the tempering point over 72 plus hours so it probably isn't just the cold but also the tempering doing something. It does help though and in some alloys the difference is shocking. I was skeptical at first and cautious in its application but now I use it a lot more. I have a technical question, How do you form and sharpen ZTA into a knife?

[@justingonzalez6448]

I have zero intention to build out my VB WRX with the FA24 to this extent, but really enjoyed the in depth explanation of the engine’s pros and cons. I could listen to you explain how things work for hours. Really appreciate the time, energy and genuine enthusiasm for what you do.

[@davewallace9048]

The level of knowledge, and the way to articulate what he does is totally amazing!!

[@y.b.-]

It's the small, almost magical , trial and error results that Mike shares in these videos that is priceless for anyone looking to do things the right way while minimizing the F***up potential that are priceless. Yes, the basics are the same regardless of the engine or the goals, but those things that wait you when trying to figure out what works and what not are the gold nuggets Thanks Mike and MotoIQ team for sharing!

[@Alex-q7m3k]

For informative purposes.. I paid 11k for my Rebuilt title 2016 WRX with 65k miles. I threw a bearing at 85k miles drove it until 100k ticking like a mf since I had a motor ready(I was getting -2FKL and -11FBK for a while cruising at under 15% throttle before it started to tick bad. But under WOT or stronger acceleration it would disappear and my AP would read zero sometimes a -2 or -4 on occasion which supposedly was acceptable) it was FBO minus manifold on a TMIC. I spent maybe 5-6kish for the upgrades? Was flex with lpfp/hpfp upgraded. 8K for a new P2P Closed deck Longblock 0 miles (costs 14k got lucky, I was going to buy a shortblock for 6k that same week) has everything done to it minus cams, 625+ rod bolt 1/2" headstuds etc 3k for STI Swap 2k for TR GTX29 turbo 7k for Misc parts & labor 1k for Ecutek software/tune Limited to high mid 400 whp because of no secondary injection :c once I get that which is another 3kish I can do 510-520whp on my GTX29. I'll run what I have until end of year and get my secondary fueling and a BL58XR (Claims 770hp of airflow) biggest you can go stock location before you spend 6k+ on an ETS turbo kit.. or if I get lucky and find another ETS kit for 3k ill snag that. For those wondering, I am indeed broke as fuck and I finish concrete for a living.

I mean even our shop car in one of our last videos was built over 10 years. It's expensive!

This puts confidence back into building an FA. Thanks for the content once again. Keep getting told the FA heads don't flow as much as the EJ, and restrict it from making power due to the water jackets being so close and can't port too much.

After watching this video how can so many trash the DIT 2.0 FA. I get not liking the weak transmission of the WRX but the engine in this format is a little gem!

[@yummyhershey5902]

The FA20 is so prone to knock that Subaru claims it’s normal in the owner’s manual!😂 The motor still seems to be generally weaker than some of its competitors, primarily Volkswagen’s EA888. Not only is that motor less likely to blow, but it also makes power a little more easily. I don’t know why, but a lot of these FA20 guys spin a rod bearing, seemingly from nowhere. Maybe it’s because of the knock combined with the non-priority oiling system Mike talked about in this video. That being said, it’s not necessarily a “bad” motor, and the FA24 seems incredibly stout from what I’ve seen so far.

[@ndog1234765]

CD009 as the FA can make enough power to blow the stock trans apart and we could not make them live very long over 400's in the power.

[@Patriot_wrx]

Would you guys be able to talk about what different turbo/induction noises are? What compressor surge sounds like vs the chirping of a BOV, diverter valve, lack thereof, etc. I got a diverter valve from Perrin and it’s making a lot of “turbo flutter” noise which I’m not sure if it’s due to it not properly blowing off air, or if it’s just the sound of the valve.

[@motoiq]

A quick check would be to disconnect it, the noise should change. Aslo see if your boost is lower, this would indicate that it is set too loose and blowing open.

[@IHadToMakeThisAccount]

Are the BRZ and WRX Engine the same head castings?

[@motoiq]

They are very close

[@slfrules1]

i think that oil cover neck has to do with the oiling priority. They ain't going after RPMs so restricting the main oil galley cuts windage and can probably help cool the heads.

[@motoiq]

No the oil passage routing has to do with oiling priority.

Thanks! I thought that cover sent the oil off to each head and the mains kinda like a coolant manifold does. Figured it was like when turbo feed comes off the pressure sensor n gets a restrictor

Do u do anything to the oiling system system to prioritise the crank oiling ? Over the head oiling ? Apart from that seems like with yur mods it’s gonna b a stout engine! When u first look at the crank it looks flimsy but the journal overlap is important I know motorcycles generally run smaller diameter journals and that is because they r concerned with journal/ bearing speed I don’t know much about that can u possibly enlighten me they don’t seem to be as concerned about that in most car engines because of the lower rpm but dare say that cos worth may have considered this in Gordon Murray’s remarkable 3.9 litre v12 running to 11-12000 rpm lol

WPC question, when you change the metal to body centered cubic will it not change to other crystallin structure overtime from heat cycling the engine or are the temperature's changes not great enough in the combustion cycle to to effect this?

[@motoiq]

WPC doesnt change the metal structure, cryo does.

[@michaelsawyer9410]

@motoiq got caught up, same question but cryo,I figure if it changes in one direction it can go the other direction but that's not always the case with crystalline structures is the there something after body centered cubic in this case even though it's a lower energy structure than face centered cubic would it get enough energy from the heat cycles over time to return to its weaker state and negate the positive effect of cryo? If so how many heat cycles does it last for before this is the case? If not does it change to a completly different crystalline structure or stay the same?

[@motoiq]

Most engine parts don't get hot enough. The only things to get close are maybe the exhaust valves. The exhaust manifold can get to the tempering temperature and possibly the range of heat treating.

Can you please send me a link to purchase the oil baffle plate?

[@motoiq]

google is your friend

[@charlvictor3714]

@@motoiq the reason I asked is because I only see an oil baffle and windage tray for EJ25 on IAG’s website.

The phone is your friend

[@charlvictor3714]

@@motoiq ok I see now you said the baffle is new. I will email IAG.

i'd love to hear your thoughts on the FA24D for the BRZ/GR86 - it seems you like the FA20, would like to hear a comparison.

[@motoiq]

It is almost the same motor.

[@rbohenko1590]

Is it recommended to replace the oil baffle along with the oil pick up tube or is it okay to just upgrade the pickup tube? And I'm assuming I should just go ahead and replace the oil pan gasket since it's already off, rite?

[@motoiq]

Yes

[@scottboyle7329]

How come I can't find the IAG oil baffles anywhere for a fa20 Wrx. I have a 2020 and can't find them anywhere??

[@motoiq]

They just came out, call them

What are your thoughts on Total Seal's gapless rings? They say their 2nd ring is able to nearly eliminate blow-by, which sounds tempting.

[@motoiq]

Old technology. Total seal has new super flexible rings that are pretty good.

[@joecrak249]

how much would something like this cost including the treatments to these parts

[@joecrak249]

PS I LOVVVEEEEEE MOTOIQ AS WELL AS THE KNOWLEDGE MIKE SPITS OUT FOR US

Any suggestions for an FA to VW transaxle conversion?
