The Reality of Stock Engines & making power; Subaru WRX STI

[@motoiq]

I agree with this 100%. I tell customers 330 hp on shit California gas, 390 with E85. If all is right, this is track day safe. A little more is possible for short duration like street use. This is if the tuning is perfect, the fueling, cooling, and everything else is great, and the engine is in good shape to start with. At higher power levels you are one knock event from killing it so it is all about the tuning. The tuner has to be smart and understand Subarus.

[@josephmatuszak3855]

As a dyno guy... I seem to see that 430whp is about the end of what may stay together(stock block daily), and that's assuming good fuel and not doing sustained side to side G-Load. After that I feel it always benefits the user doing something more substantial in the block/heads/gaskets. Depending on the "stock block" year/type though, you could be only safe around 350whp...

[@Smeedia]

I’ll tend to push it a little farther but definitely depends on a lot of factors. I’d say 400 is typically a good spot to stop where you can get some decent life out of the engine as well. Drivers style also plays a HUGE factor

[@longdomedia]

Great info on the EJ series. I am really curious to see what the limits are for FA24.

[@RSXengineering]

The crevice volume (area between the top of the piston and the compressio ring) of a oversquare engine like the EJ is naturally bigger and thus increases hydrocarbon emissions. Gas gets stuck between the cylinder walls and the pistons, then get expulsed on the exhaust stroke. This is why Subaru had to use small ringlands, higher up on the pistons, which makes them weaker, especially during detonation events.

I have a wrx too and I’m debating swapping the engine jus for these reasons

[@kylekennedy21]

Speaking on built 2.5’s sticking a 2.5 in a 05 wrx, I have decided to just go that route so I can have more head room for power. Would you do the hybrid or make 2.5 heads work? I’ve seen parts to make the 2.5 heads work just can’t find a good enough set of castings to use

[@Smeedia]

Personally I would just use 2.5 heads. You can scoop D25 heads for a decent price on market place or eBay. You can do a hybrid set up if you want to. Don’t see it done as much anymore but can definitely do so if you want to 🫡

[@kylekennedy21]

@@Smeedia I’ll have to keep looking, I’ve decided it’s probably better to just build a 257 vs building a 205 lol

[@Msngr0fd3ath]

What is the difference in the engines in the wrx vs sti?

[@mryork_]

Im hoping to be around 400whp with a forged piston stock rod ej20x with a TF06-18k. Its been a solid motor up to this point and im fine with the torque loss of 2.0. Ideally i find a ej22T block or i get a thick walled 207 block. Switching to spec b 6 speed at the moment as well

What are the biggest differences between a Subaru vs Porsche boxer engine?

[@Smeedia]

Tbh depends on the Porsche engine. The turbos and most newer ones use dry sumps. On some older P cars the cylinders actually bolt onto the case halves

[@Infrared-6]

330 whp 350tq stock longblock 150k miles. Still makes 130 comp.

[@PowerRageSTI]

Great break down bro

[@Smeedia]

Thanks buddy 🙏🙏

[@itsrandall119]

Would you recommend forged internationals for a sub 400 whp daily driver (no track use)

[@VladooDIY]

Running stock power with sleeved chamber, 14mm bolt, forged piston and stuff. Still afraid to push at the track :( . Please, be gentle with me.

[@rowebil00]

Hey, I got a question I hope you can answer! I hate to ask forums because I know the hate I will get lol. I have a 2012 WRX Hatchback in rally blue that I love. It went from 49K to 215k without a single issue other than the clutch, brakes, tires, and headlamps. Now it has low compression in a cylinder. The car itself is in great condition. No rust, no tears inside, carpets have been always covered by mats, etc. I want to drive the car but inspection won't pass due to engine fault with cylinder. I'm curious, should I just buy an engine from eBay? They say compression is between 130-140 in all cylinders, and the engine looks VERY clean, but not clean to the point where they cleaned it just for photos... It is USDM but they don't know the mileage :( OR do you think I should rip apart my engine and rebuild the short block? I have the money but I don't want to stick too much money into this... but there is an ROI, and that is I get to drive my truck less... if I keep driving my truck, the worth of it is going to decrease more than the cost to put in a new engine into my Subaru and drive that instead. I'm good with my hands, I have tools, I've done this work before but not on Subaru (Mitsubishi is where my mechanic experience comes from), I have a truck, I have a place to work on it, etc.

[@marleneduke6390]

Very Educational. Any chance this video can be made for wrx FA20 I’m at 371hp/349tq on flex fuel tune Dmann with some other bolt ons thanks either way I love me some cur purts ✌🏼

[@123cornflakeman]

We need the fa24 teardown. I want to see if subaru really created thier best engine

[@C211sti]

What are your thoughts on a open deck block with forged pistons & rods? What is the power threshold/realizability in your opinion for that set up

[@DonSlahern]

Great episode! With extra wooooooooooooo! 🤪

[@Smeedia]

🥳🥳🥳🥳

[@steeveamedee5021]

Tanner what about Fa20 my 2015 have 203 000 klm I have no problème whit it im on stage 2 flat whit the accesport in i have the part for stage 3 im waitting for the header soon and my wrx 2015 running very well

[@AKGWolf]

comments on the ej20x? everybody hates them but they have forged crowns on the pistons, forged rods and crank, and a better turbo. idk why everybody hates them, at its heart its just a better ej205 from the factory

[@chacelarsen50]

There's no such thing as a forged crown. Stop perpetuating this damn bs.

[@3obardThawn3]

Great video!!! Thank you for posting...

[@NotWBT]

I have a 94 wrx type RA (EJ20G closed deck) 144k km's 148-152psi across all 4. What are my options for 350whp? Is it worth it to keep my ancient engine since its closed deck or should I just do a v7 drive train swap since parts don't exist for these anymore?

[@ohnaw223]

I need an opinion: I am daily driving an 05 sti, Freshly rebuiilt heads and new block at Auto Science, a trusted subie shop near me. Although the block is stock, the internals are wiseco forged, and its tuned very well at 24 psi on a blouch 1.5xtr on Flex Fuel @ 440hp If daily driven normally with the occasional pull, would the motor last a while? Theres also a million other supporting mods like Killer b ELH, pickup, baffled pan, AOS, Oil cooler, etc

[@alb12345672]

I'm looking at a 12 Forester XTT with 110K. I want it but the ringland scares me. This is video helpful. Do stock EJ255 have problems before 150K? If I get it I will always use 91 gas :lol:

[@Smeedia]

I’ve seen factory engines go all the way to 400K miles. It really depends on the life it lived tbh

[@camrongoodall]

Just torque everything down double the manufacturers specs and it'll last forever 🤗

[@Smeedia]

lol this sounds like an experiment that needs to be done 😂

[@camrongoodall]

@@Smeedia lol you first 😂

[@DarkWolfWRX]

Quite enjoying the power we can pull from these stock FA24s 😈

[@stanleylam2159]

Will it be easier to maintain temperature like oil and water heat on close deck engines? or just a build one like RA block will hold.

[@tylernorthrup5471]

Hey Tanner great vid 👍 - question: I'm on a stock block 15' sti - I seem to be pushing coolant, probably a lifted head? Not seeing any leaks when it's parked but am constantly topping up the overflow... will a leak down test confirm this suspicion??
