TLDR FA24 absolutely DESTROYS the FA20. Intake and Tune on the VB gets you to 320whp/330wtq+ ....VA doesn't even crack 300whp with a tune/intake (more like 295-300whp/300-315 wtq). FA24 is just a MUCH better engine, more modern, better gains, WAY more linear, much better driveability, and MUCH cheaper to modify/make power. FA24 FTW easily. VA Fans will get mad, but the FA20 is a modern EJ205....The FA24 is a modern EJ257 and simply just a better engine.
I wouldnt say VB "destroys" a VA but VB is definitely better bang for buck with FBOs or more HP per dollar gains than the VA. VB has a bigger factory turbo but the fueling on VB is more better than the VA. I remember seeing a video of a tuner graham from boosted performance saying it has a higher fueling capacity or headroom for fuel versus VA. IMO, i think those two factors are why gains are better in a VB, bigger turbo and fueling. In terms of motor like the rods of course VB rods are wider and made better. But you comparing both FA motors to an EJ is so wrong on so many levels. You are comparing port injection to Direct injection which you just cant lol.
I DONT AGREE WITH THE EJ20=FA20 AND EJ257=FA24..THE EJ20 HAD THICKER CYLINDER WALLS AND BETTER COOLING THEN THE EJ257 STOCK FOR STOCK..THE FA24 ISNT JUST A BORED OUT FA20..ITS A DIFFERENT BLOCK THEN JUST A BORED OUT FA24 MEANING THE CYLINDER BORES ARENT THINNER LIKE WHAT HAPPENED WHEN SUBARU MADE THE 2.5L EJ'S. LOVE MY 2012 STI BUT MY VB WRX IS JUST SUCH A GREAT CAR. ABSOLUTELY LOVE IT. STI HAS BETTER GEARBOX AND ACTUAL LIMITED SLIPS BUT IVE GOT A PALLET WITH STI DRIVETRAIN WAITING FOR MY VB, SO ILL HAVE TO BUILD MYSELF THE STI SUBARU DIDNT. BEST CHASSIS AND ENGINE EVER SO ITS CRAZY SUBARU PULLED THE PLUG ON AN STI..😢
@@k20a2toofast4uI think you might be heavily underestimating VB platform. There’s so much untapped potential still Once the stock ECUs are fully unlocked I can see vbs becoming a 4 cylinder b58 in a way that it puts powers down with ease without having to spend a fortune. Just look at the numbers sti Mikey has been putting on the stock motor. That thing lasted couple months of brutal drag pulls at almost 700 whp on stock internals. And he only blew the motor because there wasn’t enough oil
@@Habibi_exe stock VB ecu is maxed out. There is so much you can do to a stock ecu lol. A standalone ECU like Haltech is nearly the cost of a new car. Few ppl who doesnt own a performance shop has ran haltech. A VB will NEVER EVER EVER be like a B58. A EJ25 is superior when it comes to being a all out race car. Case in point, project midnight why did Subaru swap out the FA motor and put in a destroked EJ25 lol? Port injection and the EJ motor is just overall better. Any tuner will say EJ is better for a high hp car 🤣.
I had nearly these exact two cars. TBE/intake/3port/etune '18 VA and catback/intake/FMIC/etune '23 VB. It's not even close. You can't just compare peak numbers either. The VB makes more power everywhere and is faster than my Blobeye STI was with similar upgrades to the VA. Plus it's just a way nicer car in every way.
340 WHP is a crazy gain. Let’s put it into prospective. WRX vb comes with 271hp. When Dyno it comes out to 235-240 whp. On average engine hp loss to whp is 15%. This means to get an approximation of what the engine hp would be 340/.85=400 engine hp. That’s some crazy gains.
Compare it to an Evo. I feel the VB is similar. Both can only go to 400 before the transmission pops. Also, an intake and a tune get significant gains compared to the STI.
that is false for a vb and a vb is far better mod for mod than a Evo. it’s the only subaru that gets more hp per dollar out of any subaru that’s ever existed
The head starts to lift at 400 + horsepower, allowing coolant to seep in. That’s coming from a lot of tuners who are pushing the VB platform. That’s why a lot of people replace the head studs when chasing big power on the FA24. And the trans usually gives out over 400 as well. 3rd and 4th usually blow. Which is why we are seeing STI transmission swaps. I am following another account where the guy says he has a reinforced stock transmission. Which I am really interested in because I prefer the final drive of the VB over the STI. And yes, the VB gets more hp out of any Subaru that has existed. The running joke is that it has Evo parts on it. We all know the Evo made more hp per dollar over the STI and WRX. One could make significant horsepower with just an intake and exhaust on the Evo. I am seeing the same on the VB. A lot of the issues once you get to 400 and above, are pretty much the same I saw in the Evo’s.
I know this isn't related to the title of the video but stock for stock the fa24 felt better to me. Can only imagine pro tune would end up with the same result.
Good video. Now that iag has started selling fa24 closed deck short blocks I’m waiting to see the numbers from those. And start seeing what people actually do with the car in the aftermarket.
Stock? Fa24 every. Single..time. crazy torque band, cheap power. Almost no mods needed for fairly big gains. Even against an STI (because that needs expensive mods, and it has higher drivetrain losses).
A few other factors… the VA wrx has more revs to play with.. the vb has a very small band of revs to use.. VA has another 600-700rpm… it’s not just peak power you compare but also usable revs. I like the VB but it has a diesel low rpm limit.
Very educational as usual. Ok, for comparisons; lets say vs a Golf R, Ford Focus, Volster N, is the new Prelude out? Civic type R. Now also, a lot of people getting this car will drive it in snow. What about comparing it with a VA WRX in a few inches of snow? What about comparing it tuned vs an Audi S4 in a few inches of snow? Vs others in snow also.
Well, this is good news I didn't make a piss poor choice on buying a brand new car after almost 15 yeaes. Glad I skipped every other generation of these car's as they're pretty mediocre at best. Im more interested in longevity & how expensive repairs are. So far a flat tire is costing me ~350$ and a week "in the shop" at the stealership. Cheers to more good news! #VB
The looks of the VB WRX are horrendous, to add insult to injury discontinuing the STI just makes the new WRX an emissions compliant car, The real WRX’s died in 21 with the STI, only other recent offering is the BRZ TS and they are hard to find and will be discontinued soon as well

hang on, what? There is no way for us to understand the correlation between engine cycling and power output, we can run 100s of dyno runs to understand a coefficient to estimate the power. But we are talking units of measurement of time that are in the wind here. It may make it more fun to drive, but a higher reving engine doesn't change the power delivery. We are assuming peak power delivery here which for all intents and purposes happen close to the blinking of an eye in terms of nearby metaphors.
Tuned VB has a 6500RPM redline. VA has much less torque down low and completely dies off up top after 5000RPM. VB is much more linear/always in the powerband and just feels better. This is coming from a dude who owned a '21 VA for 2 years and traded it in for a '23 VB. Stock tune on the VA was also horrible. No matter which way you slice it the FA24 is just a MUCH better engine than the FA20. Also, something to consider is the VA is running about 18PSI stock while the VB is at 13PSI. The VB/FA24 is just under much less stress compared to the FA20 and has way more room to increase boost/tune. Hence, why an intake and a tune on a VB makes it a monster.
Agreed on some of the fronts here, also owner of a protuned va for 2-3 years and now this vb. Just trying to say rpm is like any other engine variable, it isn’t necessarily representative of anything.
@@AutoEnthusiast. It’s not about peak power but average power over the usable revs.. the VA stock for stock is actually faster. Because it has more revs and higher average power.. VA makes its power 4000-6500rpm but vb can’t get past 6100rpm so the next gear slots in at a lower rpm also where the VA is already a few hundred rpm higher.. can’t just consider peak power numbers as you cannot always drive at peak power.. the VB is the better engine but not quicker.. its actually a suv engine and is t really suitable for a sporty car with its diesel like rev limits

What engine mods did you do to the VB I just got one and want to know
A great video brother. Happy New year. Please do the VB WRX vs the 2020 WRX/STI. Happy new year.
Thanks! I already did that video! It’s on the channel!
Good video. Now that iag has started selling fa24 closed deck short blocks I’m waiting to see the numbers from those. And start seeing what people actually do with the car in the aftermarket.
What wheels are on the vb are those the avid av20?
Please compare with other WRXs and with other makes & models.
I have a turbo back and was wondering if it is still reliable? I have a etune from dmann
You are probably fine! How are you knock numbers? Dam?
Stock? Fa24 every. Single..time. crazy torque band, cheap power. Almost no mods needed for fairly big gains. Even against an STI (because that needs expensive mods, and it has higher drivetrain losses).
Idk if think depends on the mods but also I have seen impressive hp gains on the fa24
i had a 2021. the 2024 feels faster!
holy wheel gap on the vb 😵💫
Yea but it’s pro tuned
@@nathankamholz5068 and for $300 he could make his 340whp vb wrx look better with some lowering springs

Most of the tuners are raising the rev limiter to 6500+ so they're pretty similar.
The fa 20 revs higher but it makes make max hp at lower rpm than the vb an also makes power later than it giving it a much smaller power band
Very educational as usual. Ok, for comparisons; lets say vs a Golf R, Ford Focus, Volster N, is the new Prelude out? Civic type R.

The snow makes it a lot harder, I need a race track for that! But thank you for the recommendations!

Aren't you the one in every comment section talking 💩on the vb?? Lol ok bud
The FA24 engine is 20% bigger. The gains aren't that impressive. I say just buy what car you like.
that doesnt matter its easier to tune and make more power. it can make 400hp easily with the cobb stage 2 $2100 for the kit. that's cheap
Small channels gather here 🙏🏽 let’s grow together this New Year 💯
Bit of a waste of time, really. Not an apple compared to an apple, is it?
Is it not quite literally the only equalized comparison? Lol
