My man!
Hi I would like to know what size of itb you used?
ITBs are the sounds of heaven 🎵
They sound so GOOD!!! I actually think the RBC intake manifold is louder though for whatever reason. Maybe its the pipe length. Your right though
the k24 cams is killing this setup try and get some k20a or drag cartel drop in cams
That heat definitely a killer especially with itbs. I still want some on my minime 😆😆
Awesome video, as always, brother. God bless you.
Wow great video i appreciate your time and effort in this texas heat
We have been setting high temp records in texas
110 plus everyday
Plus love the new intro
You daughter did great 👍
Thank you and yes it’s been toasty
Different fuel rail on both set ups though?! Great content dude, keep it up. I've got the euro (GB) Type R, so please keep these vids coming 👍🏻👍🏻
God bless! I did a long time ago in my ep3 a k20z3 head but I install also z3 pistons. If you install high compression pistons will be awesome.
Yea stock compression is killing the power too
Bro love the ending of the video keep it up brother
Thank you 🙏🏻 God bless you
Nice vid keep up the hard work!
Thanks, will do my best! God bless!
Check out the carbon Tegiwa intake man! I think it would be perfect for your setup! I got one on my rsx type s! Sounds amazing and actually feel a difference. Going this Monday to get dynoed we will see how my budget fbo k20z1 does. Love the vids dude
Thanks and not looking to spend any more on this setup right now keeping it budget budget but hard to do when I have to provide content for y’all lovely people ❤️ I am always open to try some new stuff sometime in the future
I just discovered your channel trying to figure out if obx itbs we're worth it. I love how you actually went in depth on before and after Dyno runs ECT, but what really caught my attention was the "God Bless You Guys" in the intro of every video, then I seen your scripture verses on ya car and coil plug cover and I hadda subscribe. Love it man keep doing what your doing regardless if you feel like it's not getting you anywhere brother, we can do all things through Christ whom gives us strength! God bless bro I'll be keeping up with ya channel
AMEN TO THAT!

Hi, awesome video, great insight and info. And with a beautiful message from our Lord and savior, and as always and awesome outro. God bless y’all.❤
What mpg are you averaging when you daily it
Run to win!
On a K20a2 full stock, with 52mm ITB (Jenvey, not OBX) I made 230Hp and 230Nm
Your head flow great, but you don't have enough compression for the cams to reach great power numbers
Needs better cams for sure. TSX cams would be ideal.
@@user-oc2nf1ez8wI have k24a2 2008 TSX cams
Yes the compression and heat are the only issue I’m having
I would like to know what size of itb he was using
That first dyno comparison, was that a misprint? The A3 made more power all over than the A2 head swap? Was that because the swao was done and dynoed before tuning, or on different days, the a2 being super hot temps? Just dont make sense even without tuning that the a2 head swap would make almost 15 less hp?
2:37 wait a min. So it made more power stock then with the head ? 🤔
Probably 185hp at the crank for the 161whp setup. Its close! Nice man. Keep at it 💪
yea the temps and low compression killed the power output but hey a cooler day will yield higher numbers
it's only 10% drivetrain loss in fwd cars, so it would be 177hp at the crank...
@@402roadrunnernever seen just a 10% loss. Lowest I've seen is 12% but usually 13 to 16%
Great intro! Please do a video on the cold intake down to bumper. I as well dont want to move battery. Is it possible to put battery down lower on drvers side?
You can relocate the battery with a kit from Nisda on the passenger side but i think my cold air intake i had from Rsx might work
@@TexasHondaChannel please send link of the cold intake you used. Thanks 🙏
Getting rid of itbs?
I made 235whp 165tq out of a k20a2 with z1 cams, uncut rbc, ktuned 72mm tb, ktuned hearer, rdx injectors. If you are going to use the k24 bottom end you should be making 250whp 200tq, ive stumbled across your channel before, dyno numbers always disappoint, i think you need a new tuner
I was disappointed with his d series supercharge with speedfactory camshaft.
There's a good chance all the valves bent with the k24 rocker arms when you had no compression and were cranking it. Not by much but just enough to create a low power number. It will also create large back fires and that pulsing sound heard from the itb at a lower rpm when under load.
A3 bottom plus a2 head with no aftermarket mods have consistently netted around 175 to 185whp. So something is not right in your valvetrain.
Can i contact to you for more info
VTEC definitely did not work can't even hear high cam good video but definitely would have made WAY more power with high cam turning on
could you make up for the heat problem whit a w/m injection?
Yes to a small extent.
Need to get rid of the a3 entirely, i truly appreciate your r&d tho!
Yea except it’s a strong setup with no true issues so not worth ditching just yet lol
Should've done mo intake neck with no venturi
With the low compression it will love turbo🎉
I know it would but I’m staying all motor. Thanks
I have seen more k20a3 with type r head putting near 200hp
Heat kills hp and thats what we are fighting
How long is that stock a3 block going to last for going past 8k? My ep3 has a k20a stock internals with kpro but the rev limit is set to 7900 but it still scares me because of the big oil pump
Also I have the hybrid racing 3inch cold air intake and I didn’t have to relocate the battery or anything but just a recommendation
The k20a3 and the k20a2 type s engine have the same oil pump. Don’t worry your good 😎👍🏻
@@ethanfreeman5344thanks appreciate that. I’ll look into it
I met you at the car show in copperas cove I would love to do a collab with you bro.
Heck ya. Which one were you? I met a lot of people lol.
Im surprised its like the ITBS were chocking at the top of the rev range😮
Yea it was because they were too small for this setup. If i got the ITB runners port and polished it would help a lot too.
What are you comfortable revving your k20a3 to?
8,100 is comfortable because it don’t drop oil pressure until about 8,600rpm so 8,100 is a safe number for me personally. Gives me a buffer
@@TexasHondaChannel once I get mine stickered and insured I’ll be sure to test
Pistons needed to match cams and oil pump
Oil pump is a k20a2. The k20a3 and k20a2 have the same exact pump
Wait, did you install the type s oil pump?
The k20a3 and k20a2 have the same oil pump 👍🏻
@TexasHondaChannel woah... that makes me super excited!!! I have a stock ep3 so it was daunting about the "fact" that I had to pull the engine to change the oil pump, very excited for the future of my ep3 track build!
Whats Exahust You Using Sound Pretty Quiet
Is this with the k20a3 head?
Nope k20a2 head with k24 TSX cams. The compression is 9.8:1 and the heat combined is killing what Would be power
This heat is killin ME lol, I work 10 hour days in an auto shop 🫠. I have an ep3 as well I live in southeast texas. Yeah the heat bogs everything down for sure.
That’s really interesting though, it has the same compression as the k20a3, deck height is the same, just larger lobes and both cams have vtec.. cool series man
Small turbo with a tune and it’ll probably be like an modern hot hatch. Love it man
🔥🔥🔥😇😉🍻🍺
I wish they made itbs for j35 motors lol love to have them .. sounds Amazing ..
Yes!!! I bet someone will make them eventually
If you have access to a CNC machinist, a manifold is basic work for them. It's just a matter of if they're willing to do it/have time.
HAI, hot air intake
Vtec ain’t cracking
Find some a2 piston and slap it on ill make a difference
Yea if im tearing out pistons its not longer gonna be a daily build lol. I would rather swap the engine with the Full A2 i have sitting doing nothing. I don't do bottom end unless im going big. Also nice to see you in the comments here :)
Just put a k24 in the car at this point the number the car made is mind blowing low
The engine is strong. I don’t want a k24 in it. The heat kills all power. Trust me been doing it long enough to know the heat is the X factor in all this. As soon as the temp drops I’ll prove it.
I agree, I have a k24 in my ep3 with skunk 2 long tube header and its insanely fast, I beat my friends 08 civic si by like 2 car lengths. At this point it feels like a waste of time and money trying to make k20a2-a3 combo work.
Time for a turbo 🤔
nope I have turbo K content feel free to check my other videos.
My a3/ a2head made 189 156
Im positive if i go back when the temps aren't in the triple digits it will yield similar.
@@TexasHondaChannel 189whp with k0a2 head on a3 block,type s transmission, kpro, stock prb manifold, ecut out on exhaust mid pipe
Should have been 220
@hevertpacheco7870 I have a k24a2 now so I probably am around 220whp now
360pganggggggggg
The HD video isn't done yet lol Most people don't watch right after i post. My bad lol
@@TexasHondaChannel im just always ecxcited as i have my own channel im growing and im always happy to be the first few people to see it before it gets fully rendered. love the channel. God Bless
@@Chad.Dawesome and yea it’s appreciated for sure!
