K24 240SX Build - Why K24 is BETTER than SR20

[@BlueberryWrap]

They make over 450-500bhp stock block in civics imo its best bang for buck I’ve spent a shit ton on my sr if it blows then it’s going and a k24/20 is coming

[@BoostBrothersGarage]

They are impressive engines for sure.

[@chubscub]

Well an engine with 80's tech versus a engine from 2001

[@BoostBrothersGarage]

Yeah I mean it was obvious that the K is a better overall engine but I was surprised that it was within 10% of the upfront cost to swap.

[@davidottobre188]

Ya the tech isn’t the argument, it’s more the money for ranges of power you’re shooting for

[@youtubecomments5951]

It’s more of 90’s engine that 80’s

[@chubscub]

@@youtubecomments5951 it was designed in the 80s and first came out in 89

[@BasinMotorsports]

It's starting to look like a fancy garage with all the banners. Dig it!

[@smoothctr1]

My 200k mile k20a2 does 30 min sessions no problem. And if it blows, I can get another one for $800-1k. Can’t beat that!

[@BoostBrothersGarage]

Awesome engines!

[@_eddielee]

These 3 things here. You want to explain those a little bit? Proceeds to talk over David the whole time.. LOL

[@si_calloway5778]

I recently purchased a JDM K24A, and a BMW 6-Speed ZF Trans, Waiting on my TF-Works phase 2 s13 kit to get shipped out, and I am already at $4,700 bucks. That being said I have not purchased type-s oil pump, VTC gear, Clutch, Driveshaft, Wiring, ECU, Intake manifold..etc.. I would say that $5K gets you the bare essentials to physically bolt the longblock/trans in the chassis..

[@BoostBrothersGarage]

We weren’t using dual clutch for this comparison

[@si_calloway5778]

@@BoostBrothersGarage neither did I, dual clutch kit is $3500. I opted for the source you're own clutch at 2600

[@josuecolon8596]

Please if it’s possible and not too much to ask.. but please I would love an update on what has been going on in the build and progress you guys are taking on it.

[@BoostBrothersGarage]

It’s coming soon! This build has been kicking our butts but content will start flowing again shortly.

[@bingoberra18]

I think if you use your car as a tool ie drift/race car it only makes sense going K-series, it is defacto the best 4 cylinder obtainable engine ever produced. But seeing as everyone and their moms K-swapping something, its kinda like the LS swaps, it gets boring pretty quickly. If youre building a street car it could be a bit classier staying within the family.

[@BoostBrothersGarage]

I think that’s a fair assessment!

[@davidottobre188]

Ya that’s a fair take. This is purely a performance car analysis.

[@latuba2478]

No class, just want fast

[@andresramirez5466]

Are interior parts and exterior panels easy to get for a 240SX?

[@rbs14kouki]

If i had to Start all over today , i would do a k24 ... but my s14 came with an sr all ready And my p11 vvl head cost me 500$canadian ... i would not pay 1500usd for a ve head today ... lets just hope i dont damage my engin other then pistons lolllll

[@BoostBrothersGarage]

500 Canadian was a steal!

[@markchacon5971]

I would love to see a cost break down that would be great ! Great video I really enjoyed it thank you !

[@BoostBrothersGarage]

We can do that, thanks!

[@kswap240tsx9]

I have a list for my s14 k swap and it’s about 10k. Engine- K24a2 Transmission-CD09 Turbo manifold Turbo kit Manifold intake-Ktuned TB-Kruned K swap kit-TF kit ID injectors-1050cc ECM- haltech elite 1500 Engine harness-wiring specialties Clutch-6puck Oil catch can AN lines and fittings Fuel rail/filter-radium All parts listed are new I am pretty sure I am missing something but that’s just for the swap without any internal work. I am sure it can be done for less with used parts

[@hegaliandialectics4289]

@@kswap240tsx9 What do you think it could cost for a na swap? Just using TF works parts and a bmw transmission it was like 9k including motor. Not counting engine accessories and random bits. That was my estimate just using TF works products though so their driveshaft their header/intake/exhaust ect.

[@kswap240tsx9]

@@hegaliandialectics4289 for all TF complete K swap kit, including driveshaft, intake, headers, harness, radiator, clutch would be around 6-7k. I’m not including engine/transmission nor any fuel system, cooling system or engine management (ecm). All included, you can be looking just around 9-11k. You can always get a cheap engine/transmission from the yunk yard and drop the price a bit. I’m already looking at mine and it’s around 14-15k to complete but it’s always something coming up that potentially will raise the budget…

Sounds a lot like the 07K vs AAN swap debate, Mike.

[@BoostBrothersGarage]

Very true!!!

[@davidottobre188]

I thought about the 07K 😍

[@IamCredit]

Nobody thinks an SR20 is better than a K-Series.

[@BoostBrothersGarage]

Surprisingly there are a ton of people making that argument on the FB groups. A lot of whom didn’t watch the video and even understand the argument lol.

[@IamCredit]

@@BoostBrothersGarage Bahahaha If I wanted to get informed opinions...Facebook might be the last place I go for that.

[@BoostBrothersGarage]

It would be funny if not for the fact that people actually believe the BS they say.

[@markcrizaldo881]

As for me nothing is more superior than the 4g63 mivec turbo.

[@POVShotgun]

I do

[@sdshakazulu4268]

I dig it… but I love my ka24de-t, came with the car

[@toad0720]

Sorry to drag you back to it, but what is the latest year 2.5 L 07K motor you would advise using.

[@BoostBrothersGarage]

Personally I say 08-10 but you can use any iron block 07K

[@toad0720]

@@BoostBrothersGarage thank you very much. Been eyeballing engines lately. You recommend the forged TT-RS crank as well, or don't bother? Considering purchasing your conversion kit in a bit.

[@rars0n]

@@toad0720 You can buy a brand new TT RS crank straight from Audi for a little over $1400. IMO that's not a bad price at all for a brand new forged crank. Look around and you can find them for even cheaper. Depending on what your plans are for the bottom end and overall build, I think the TT RS crank makes a lot of sense. I probably wouldn't bother with it on a low boost or naturally-aspirated setup, but on a built engine, why not? It's a relatively cheap upgrade for a ton of peace of mind.

[@toad0720]

@@rars0n thanks for the reply 👍. Haven't decided on mild or wild yet.

[@rars0n]

@@toad0720 Tell me about it! I've got a Mk2 Jetta sitting in my garage waiting for a 07k swap. These engines are disgustingly cheap! But I want to build it right. Can't decide if I'm happy going N/A or if I want a 400+ hp boosted build. I think I might just start out without a turbo, but build the engine for future boost, because I'd really love to see how the car feels and sounds without a turbo before I go and put one on there. Plus, I can get the car mostly sorted out and running well before adding the extra turbo parts. I've been eying up the Xona Rotor turbos ever since Forced Performance announced them (I've done a lot of business with FP in the past, they're a great company). So I'd really like to try one and I think there's a couple great options for the 07k.

[@tturi2]

my problem is that once you buy the adapter flange, an sr20 isnt any different in cost

[@informKPBoateng]

ah so cheaper = better , i seee

[@Grainsauce]

Another thing to keep in mind is it's a lot more work to get everything to fit and work properly, go watch speed academy's channel on all the issues they ran into when swapping to k24. I can't believe the ebay prices now just last year they were around 3k, I know because I was looking when I got ready to rebuild my sr20det

[@BoostBrothersGarage]

That’s a good point. We’ll definitely document how tough it is. I think their biggest issue was the oil pan which hopefully we won’t have to worry about.

[@TheDroidKilla]

But is it BETTER than 07k?

[@BoostBrothersGarage]

Honestly? Maybe haha. Not sound, or cool factor, but capability it likely is.

[@signature11.81]

Hmm....this vid proves that obtaining the k24 and parts for it is more economical, but when you said better i thought stronger or more powerful....

[@brandonsmith7265]

You can make 500 on a stock k24 without opening it up. You have to build a sr20 a lot to make that kind of power

[@02maddman]

Ahhhhh the hate for the sr is real smh, ill stay nissan

[@kenpartytix]

Just needed a VVL head swap....

[@joelpizarro2915]

No vvl head a sr20det rxs tranny with swap plate sleeved block up the boost and we good to go we make more torque then Honda all day sr20 for the win and engine cost all depends on who you know if you a race car guy you know Damm well you not paying top dollar to fix it just saying

[@lennixsingh626]

All an sr20 needs is a VVL head swap
