- A K24 Swapped First Gen CRX is a NA BEAST!
By Aaron Gaghagen and Brian Gillespie
Now that we have the K24 running in Vic's first generation CRX it's time to see how much power it makes. It sounds so good! We also wanted to see how swapping in the big block K series effected the weight balance. After all, it is Vic's race car. It was corner balanced before with the B16 he used to have. Now with the engine and transmission on opposite sides, it will be interesting to see the effect on handling.
To do your own K24 first gen CRX/ third gen Civic swap we have compiled a parts list from this build.

OMG 200 lb ft NA in a CRX is like Honda heaven lol
💯
Bring back the NAs!
Lightweight cars really are the most fun. One of my last Hondas was an ‘84 CRX with a modified carburetor and it was one of the most fun cars I’ve ever had. I drive a 1LE Camaro now, to put it in perspective, and I’m always jealous when I see an 80’s or 90’s Honda.
Honda's are just fun cats. Great driving experience
That turned out soooo nice! Literally looks like it belongs in that engine bay.
The power to weight of these 1st gen CRX with these newer Honda swaps are phenomenal. I had a 1st gen CRX HF ZC brown top in 1995. It was quick for it's day.
All you need is b20 non bred with 404 crowers and I forgot which head i think p8r ur in vtec all day pretty much. I follow and watch a lot of these swapped in 12-11sec
@@vucci8378 p8r is a non vtec head
@@manny4486 yes that opens same diameter as vtec....
@@vucci8378 the cam lift is as much as vtec lift?
It's nice. you can squeeze a little more power out of a K24 if you fit the K20 head onto it. It flows faster.
Stabbing the throttle to correct oversteer is such a huge blessing
Can’t wait to get started on one of mine! So awesome to see this build wrap up successfully! Love it
Thanks for watching! It’s so quick with that wide power band.
I can't wait to see it 🫣
I would love to see you guys do a 88-91 Honda prelude k swap build. Or any motor. The 3rd gen prelude is suffering from no aftermarket support.
2nd gen too!
I'd wanna see a fifth gen j swap.
I’m pretty sure this is the same car and owner I saw a feature about probably 20+ years ago. Car looks the same (Kosei wheels and clearanced front fenders), and the owner’s name was Vic. Cool to see this car loved for so long.
It is, we talk about that feature in the first video in this series. Good memory!
I absolutely LOVE the CRX! Especially the Mugen editions ^-^
Check out the ones at The Honda Meet! ruclips.net/video/EAZg_RgwOyg/видео.html
I remember my first CRX it was an 87si that had like 365k on it with no rebuild as far as I knew. It ran and drove good just smoked a little. I got it for $300 back in like 2009. Some rich kid drove over the top of it in his lifted truck and his insurance gave me 3k. I do miss it though.
oh man thats sad
Guy here in ireland built one, with a b16b block with a b18 crank, it produced 243hp, and weighed well under a ton, we worked out it had a power to weight ratio that embarrassed most super cars of the day. It was seriously quick.
This motor has put out more than 500hp naturally aspirated if you want it - 1400+hp with boost 😂
@@TheFK8Life His was a time attack car, for circuit racing, I dont see any civic/crx of that generation requiring that kind of power in that situation. In a drag race yes, but usable power is limited by chassis dynamics and downforce etc. It is still amazing to imagine that little bean can with a thousand horsepower🤣
@TrueBlueEG8 time attack civics have around 900hp now. My daily driven Type R is around 640hp with my goal being around 700hp for daily use with a stock bottom end. Biggest issue is how much tire he can fit and weight over the front axle lol
@@TheFK8Life You need to drive mondello park in ireland to understand what I mean, it is narrow, tight, technical and bumpy. I have modified and raced several hondas myself, so I know how quick they can be
@TrueBlueEG8 25 years and 17 Hondas later I'm well versed - my bought new 1999 EK had a B18C5 in 2002 and my EG had a B20v with 225whp in 2003 1800lbs on semi slicks, full suspension.
Bumpy is a problem for older Hondas because they have less stroke and short wheel base - longer travel with a touch more weight keeps the car planted better - add in a wider track with 305 wide tires and you'll have more lateral grip available and more weight over the front axle to make use of the grip and power on conrer exit.
Anyway- have a great day
Crazy how this was a chassis 12 years ago going d16z6 was a pain in the ass, going b16/18 you was a master
What Brian said in 17:33 was confirmed by Ian Baker and Andy Hollis with their EFs
1st gens will never die...RPR ftw...
RPR for sure! Keeping alive!
I owned the exact model and color, still remember how small and light the thing was. But putting Kseries in is insane 😂
For the track k is the right swap, for daily street driving bseries with vtec and a/c...
beautifully done, keep plenty of body parts on hand as they are harder to come by now. Heel Toe Automotive is also a good source for fiberglass replacement of fenders, and nose.
Cheers and RegardS!
Yeah, Vic might go with the long hood from Marcus at Heel Toe.
CRX FTW!!! Ya'll should hit MUSSLEMAN 5/6?
That would be awesome.
These 2 are obliviously Alfa males in the Honda community and they both show their knowledge and experience
I’ve been waiting for this video!! This is my favorite build thus far and has inspired me to do a similar setup to my CRX. Thanks for sharing!!!!
Tim at xact tuning also tuned my S2k. Great guy great tuning
Fantastic to see this buttoned up. Looking forward to more footage of this thing ripping!
Yeah, hopefully we can be at the track when he’s out there.
I currently own one of these cars, an 85 CRX Si mostly stock. But I recently bought a new engine. K20A2 from an RSX Type S including the transmission, harness, ECU, shifter and more. It won't be installed for a while but I will likely pursue the swap next year when I can afford it.
Hell yeah! You're going to love it.
Good luck and you will love the power!
Can you adopt me as your grandson?
I have this 88crx si that needs some love.
And I just subscribed....
😂 thanks for subscribing! We’re going to revive the yellow Hasport CRX soon.
I love NA u dont have to wait for the power its instant.. but force induction is cool too
Can someone tell me if the motor mounts on the first gen crx/civic are the same as the first gen 86-89 integra? Want to kswap one
They are
My dream swap is here! I already have the car.
Hell yeah!
Such a sick build!
An old modded car, is faster than a modern stock car. Who would've thought 🤦
We don't know if it's faster, but it feels just as quick and that's with a NA K series with stock cams.
You are loosing like 30hp with that stock rbb intake manifold... It chockes at 6krpm and its imposible to get more than 220-230hp with it and definitely no sense putting a type s oil pump with this set up
As you might be able to see, there really is no room for that manifold in that engine bay. A lot of custom parts. There is a compact Skunk2 manifold that might get us about as much horsepower as the RBB.
@@VTECAcademyHe could use the RSP manifold from Fn2, is a excellent manifold openable with inner stacks, and it's pretty short
even the NA K24 in mostly stock form freaking RIPS. My FG2 (8th gen 2 door SI) swapped with a nearly stock (not even FBO) K24a2, making only 220 WHP / 170 TQ at the wheels, goes neck and neck with the lower end V8's lmao. It was insane going from the K20z3 to the K24a2, only 10 more WHP but the Torque is absolutely insane. More torque at 2k rpm than you were getting at 6k rpm / Vtec. That power to weight coupled with the Helical FWD LSD is an experience most people are sleeping on / have no idea about, it's much better than the common open diff lower powered FWD cars. Best part is a good K24a2 is about $1000 lmao.
The torque makes a huge difference. And it makes th engine easier to drive.
I need Brian's help again. Im reassembling my 1989 K24A2 CRX. I just installed the Type S oil pump and Drag Cartel 45 deg vtc. I also studded the head. When I drove the car before it stayed in limp mode. I believe it has a p1259 code. I don't have oil pressure switch installed. I can't find information on it. Do I use the 1989 CRX one? I have Rywire harness.
Also, is that Kswap header a 2.5" collector?
Yes, per K tuned it’s 2.5 outlet
Love this. I'm seeing a widebody to accommodate wider rubber, all the carbon fiber you can attach, upgraded lighting, real mags, and equal weight distribution......most of which you've already considered! So cool. Cassy's Customs put an LS in his. lol. Both COMPLETELY different, but fun!
How much extra oil would be safe to add if you are tracking your car? I know PFI Speed recommends it for drag racing also.
No more than 1 quart.
Nothing beats older jdm styling
So well designed.
I'm putting a k24 a2 in an ef hatch and a fully built OBD1 dohc zc with ful tilt transmission in an 87 crx now I'm thinking about kswapping it after seeing this
Do it.

Thanks for creating these videos and drafting an article/parts list for this swap. Could I use the parts list for 2nd gen CRX? Specifically for an 89 HF?I believe the only differences would be exhaust length and maybe a few minor wiring differences?
I use to have that CRX with a B16 motor and B16 transmission & it was a lawnmower on steroids!!
Great motor mounts, That K series fits amazing!
I'd still put a turbo on it.. ...GTX3071...
It’s bump him up in class though. But some boost would be wicked.
Thank you for openly sharing your hard earned knowledge! Your contributions to Honda modding will not be forgotten.
I appreciate that!
I would like to see a k swap wiring diagram for the first gen integra 86-89
I had a Silver and a Red ‘87 CRX-SI. Those things were blast to drive
how on earth are the plastics so GOOD on that car?!
Right!?! Especially in AZ with the heat.
They are showing their age!
I'm trying everything I can to trade for an eg or ek. I have an 04 tsx auto now and I want a manual. I want to keep a k24 power plant, though.
A manual swap would help kick up the fun factor.

We need a more of the vehicle 🚗 the information is crear but I’d like to see more angles on the car 🚘
Great*
Maybe when we go to the track.
Of course half the weight* with more power
👍🏽👍🏽
Those were slower than you remember, but they were so much fun!😊😊 Then you still outran a mustang/Camaro on the get go, so basically all cars were slow because of gas mileage and antique v8. You can't compare the feeling of a small light car like the crx and the fiestas. Even an R18 from a normal civic will make this thing a screamer! The k series motor is no b18 and the price is just outrageous, it completely goes against the Honda Civic mantra.
Can you please give information on brake upgrades and torsion bar upgrade keying ..Id love to k20-24 swap my 85 crx si . I've looked at scarebird conversion plates trying to figure what else is needed. Thanks!!cheeerio
I had one in 1997! 1988 black! Love it!!! Thanks from Norway 🇳🇴!!
Awesome video!
i got 87 Civic SI JDM (true E-AT) and i am thinking of a K24 swap, but i am afraid that RHD brake booster could be a problem. Do you have any thoughts on that?
Measure how far it protrudes from the firewall and I will tell you.
@@VTECAcademy so i measured it, and stock brake booster + master cylinder showed 21 cm ~ aprox. 8.25 inches from firewall
Did you ever get your answer?
@@1stGenCRXs no 😅
@@everyday_andrey let me measure mine today and get that number to you
So want to do this I have a 1987 Civic Si thats been in family since new, if you have a parts list i for sure want to do this... great work.
remastering movies is bad... but man would i enjoy 90s cars remastered over the 2023 bubble spaceships that have no soul. give us a 2023 crx that looks like the 90s crx. the new integra is proof we went the wrong way in design.
I'm old, I remember when the B-series was the swap to have in an old Honda. LOL.
The K fits amazingly well.
😂
Does any one have motor mount kit to put this motor in a 1987 Honda Civic Dx hatchback? K series
HASport same kit we used here.
Good luck with the car Victor- from Dutch
It’s going to be a much quicker car now.
Thanks Dutch!
Y’all need to build an h22a if yall like torque and revs. My 4th gen prelude makes 230whp all the way to 8500rpms with minor mods and a dyno tune. I genuinely believe h series is so slept on for no reason lol people have big misconceptions with the h22. I’ve had mine since I was 17 and I’m 25 now, never rebuilt completely original other than timing belt. Also has a h22a4 transmission. it’s been an absolute dog on the streets and handles anything you give it. It is also a handling machine, best fwd car I’ve ever driven in the corners.
I had a 1990 CRX with an H22A swap with nitrous. It was on the cover of Sport Compact Car in September of 2002. It was also on the season finale of the TV show "Pinks!" We raced a VW. I should bring that car back.
Why can't I post on the live chat? 😢
Edit: thank u for unlocking me lol. This build is so so good! 🔥 ❤
No idea why you were locked out. Thanks for the support!
I need this engine in my 1990 EF Civic Si Hatch! Like.. RIGHT NOW!
I'll pay you guys or someone else to do the work for me! Since I'm dumn!
Yes.. I did spell DUMB incorrectly on purpose! 💔
😂 200 ft lbs of torque wow and 220 hp seriously ive seen and raced plenty crx with b16 swap with nitrous and even turbo with spray they were not impressive they pulled when hit vtec but yeah no thanks they didnt stand a chance agasnt a all motor ls f body gunna need more hp to be able to claim your fast on the street or roll racing you will get slaughtered if you aint at over 1000whp your nothing these days sadly
❤️Go Hondaaaaaaaaaaaa.!😅
Theres the 350+ HP CRX all motor on RUclips its insanely fast.
Sweet! That’s gotta be a real screamer.
What did they do to get that much NA HP. I know of cars running fully built motors making 300 wheel hp, that’s about 350 crank. 350 wheel? That’s a hell of a motor!
@@1stGenCRXs compression over 13, rev limit 11k and e85 most likely, even B series can do it but they won't idle or last long
The info these guys share makes me happy that they chose honda engine swaps instead of vw's and tennis!
LOL
I put a JDM GSR in my 91 back in the very early 00s and just that bone stock i ran a low 13sec.. which for its time was pretty damn fast!
I built another motor that was setup for 280whp+ NA but when it was ready for the dyno i wrecked the car and sold the parts off.
I think i could have gone mid-low 11s with it. Which again, for its time in approx 05-06ish was fast!
The beauty of All motor, is your car always works.
All my boosted friends constantly had issues.
That's my first car. It even sounds like it. Mine was metallic black though.
I bet this car does 12's from the power to weight ratio and in the turns it does even better!
Maybe 11's...My 86 CRX HF with A20A3 has done 12.90 in N/A form on 8" slicks and open header. Engine mods were ported head, header, 9.25:1 stock pistons, and a B16A intake.
I want to find that out!
I've had 3 CRX's In my life. I still have the 3rd one and it runs great!
😍! 0:42
Please post a video for kswap to pass emissions - there is no forum of such topic - what you need and what you don't need
This is Awesome!
Thanks for watching!
I love this soo muchhh probably all I think of😂😂😂😂
The way he puts his weight on the propped bonnet disturbs me greatly...sigh
I knew a guy with this crx and he swapped it with the GS-R B18C4 everything you could bolt on it + 100 shot of NOS and he literally walked everything that pulled up…. Porsche’s, Vettes, etc etc AND this was back in 2000.
I just looked up the curb weight difference for 1st gen vs 2nd gen, it's not as much as I thought it would be. Do you think it's worth swapping a 1st gen when a 2nd gen has so much more aftermarket support and arguably better suspension design? I love 1st gens too but it seems like a more difficult swap just to be different.
It makes makes sense if you already have a 1st gen or want something different.
@@VTECAcademy thank you
You guys should do k swap cb7 on a budget
Stop leaning on the hood man you're gona bend the bloody thing.
Very nice work man that's one clean setup !!!

Thank you! We hope you feel better.
I have a 1986 in my driveway that’s been sitting for years with no engine 🤔
A K would be a perfect power plant.
Clio 182 is a good car to track. is about 900kg wet
I've seen all kinds of k20 and k24 engine set ups at Willow Springs, Button Willow, Thunder Hill, and Sonoma raceways, all are loud and Slow.
Slow compared to?
Is that Commiefornia legal??
That lucky mofo….
That’s what we tell him everyday.
What are the major differences between the K20 and the K24?
Which one has more power stock? I've been seeing more and
more K24 swaps lately but I know K20s were always great as
well. Curious what the major differences are. Hmm...
Guess I could just Google? I'm just on lunch break though lol
Lots more torque. Similar peak HP. The K24 makes more HP with similar modifications.
@@VTECAcademy- yea but the K20z3 head flows better so you need a Custom Frankenstein k24 bottom end / k20a head to make the best possible K Series engine setup. 😈
@@I_know_what_im_talking_about lol pretty sure VTECacademy already know that Mr expert.😅
I so wish you'd have given an idea of a cost range. I mean you could put a Bugatti Veyron engine in the CRX and talk about how great it is, but without attaching a concept of price/cost it's meaningless.
It’s cheaper than the quad turbo W16 engine without a transmission.
will this car need grippier tires since its so much power for such a light car?
Yep, he’s stepping up in tire size to help.
@@VTECAcademy what size? and is it only necessary for the front tires or all four?
Yes.
I did all for to help with the balance of the car. We talk about it in the video.
Stiffening up the rear springs will help keep the weight and traction from shifting off the front tyres.
I just recently got my own first gen CRX, and im having the most trouble finding parts for it could anyone help?
What are you looking for?
I have questions about a honda I have and was wondering if I can get some help or a little information if possible I highly appreciate it thank you

I get that he’s the host, but man needed to show his knowledge speaking over the “driver”. Pretty irritating.
I’m not sure I understand.
This video would be better if they showed us a video of the car actually ripping down the street instead of listening to old geezers talk for a half hour
Geezers!?! Why you young whippersnapper.
I just hate that crx 88-91 or nothing. Strictly opinion based on looks.
To each their own. I still appreciate the 2nd gens.
This is amazing. Have you guys thought about doing a AWD swap.
Yes, but not on this CRX.
Which transmission did u used
Wow! That’s beautiful
It pulls so much harder than it did with the b16.
Ohhh dilly dilly 😅
Thank you, sir!!
