Its nice to hear an engine builder say,I constantly hear the a3 is just junk,I use to point them toward your playlist I'm just tired of doing that,thx u sir
Just to be clear in talking about BARE block comparisons. Still plenty of reasons to grab an a3 but that's dependent on power goals snd how much you wanna work. Watch my other a3 videos
That valve shrouding hurts airflow though.(I'd rather remove that meat behind valves then have the compression)Have A3 and Z3 myself,both great engines!
But your right you can take a block and build it to be better than whatever u want doesn’t matter if it’s a a3 and there cheaper to get like you said so good video and keep at it
im getting a k20a3 swap on my 00 ej6 & im looking to make more power, this helped a bit 🙌🏽 so if i get a2 head, crank, rods, & pistons & swap it on my a3, does the oil squirters have to do anything with the internal swap?
Great video very educational. Hence I was thinking the same damn thing like why can't you take a economy k series engine and build the shit when everything is basically the same except for the oil squirters lol
Okay, Mr.K series God himself. I falsely got sold a K24a2 head and thought it was going to be a K20A2. Would a K24A2 head fit fine on a K20A3 block with a K20A2 bottom end. Any response would be greatly appreciated, idk what I would have to modify to make this shit work
hey man, long question but ill try to keep it short here hope you can give an advice. I have a k20a3 block with a cnc ported k20z3 RBC head (using bc stage 2 camshaft and uprated valve springs). What I need to change is the Pistons, Conrods and Crankshaft on the k20a3 block correct? And will the block be able to withstand?
If you haven’t already, get nippon racing high compression pistons, polish your rods (simultaneously taking material off the rod to make it lighter), and keep your stock crankshaft. That is a beastly block that will allow you to rev high and support the flow of your head very well. Your head is perfect.
The k20a2 has better oil cooling, better air flow, and makes 40 more hp, stock. It only makes sense to go for an ivtec motor if you get it for a steal.. A jdm k24a rbb is $900 and even if you get a k20a3 for free, you will not make as much hp with $900 of bolt ons. Therefore, for most people, it doesn't make sense. One more thing to note, the k24z motors are upgraded versions of the k24a/k24a2 (upgraded valve train and better rods/pistons etc). So k24z or k24a/a2 is best for budget, then base k24s (k24a1) then k20a3. If budget doesn't matter, get a k20c1 crate motor from honda or a 4 piston motor.
@HDVisionsMedia the k20c has already shown that it's the weakest K. Head gaksets are and issue for them and 4P blew kwpt losing them at 400whp. K20a3 has consistently made 190-200whp with a oem vtec killer and basic bolt ons and the k24a4 makes 210 with the vtec killer. Plenty of evidence even here on my channel So yeah thanks for the "insight" I guess
hey! hopefully this chat isnt too dead- I got an 08 si with an a3 swap and its boosted on e85, just wondering if itd be worth doing an a2 or z3 swap. my goals are about 500+ at the wheels relatively reliably. cheers!
Chats always relatively dead even when the channel was super active.....but I still see everything. I don't answer everyone because most of the answers are here on the channel already. Happy info hunting
@@VHBEngines thank you kindly haha. i guess more or less what im asking is what would be necessary to make the a2 work, are the mounts or anythng else different?
Can swap my 04 Tsx head for a 06 Tsx head. I want to go with my gut but I see the intake valves are different. The intake valves on the 04 are stamped with the number 5 and the 06 intake valves are stamped with the number 35 and stick out a little bit
Have you ever put k20a2 crank rods & pistons into a k20z3 block with a2 oil pump? Can it be reved to 9000? I think the oil pump will block off the oil squirters? Thanks
if you wanna stay all motor start with an A2. the A3 has no comp, no valvetrain and the rotating assembly and the oil pump cant take high rpms. youll get it done cheaper in the end.
So if I’m planing on doing pistons rods, new head the whole 9 it doesn’t really matter what k20 I have ? Cause I have a k20a3 was planning on completely stripping it down and doing everything to it
This is a comparison to BARE blocks. The engine blocks are virtually the same. If you want forged rods in your a3 the easiest route to that is to get the type s or later generation si. The a3 crank doesn’t have much aftermarket support. Plenty more details in my k series playlist
This guy cracks me up!! He definitely knows his shit, but so he should, he uses his house as a garage 😍
This sounds like a drunken genius lmao
My mans speaks like Rick from Rick and Morty😂
Javynation PR lmfao wow! That rant did come off rickish
VHB Engines lol u did get the point across tho😂😂
VHB Engines im thinking abt getting a 9th gen si what do u think would be some good mods?
Javynation PR lmao word omgg
Javynation PR bolt ons and tune if ya want a simple bump in power
I smell Jack Daniels when I watch this vid 😅
Its nice to hear an engine builder say,I constantly hear the a3 is just junk,I use to point them toward your playlist I'm just tired of doing that,thx u sir
Really helped out on my next choice for a k swap, k20a3 it is, thanks Chris 👍
Just to be clear in talking about BARE block comparisons. Still plenty of reasons to grab an a3 but that's dependent on power goals snd how much you wanna work. Watch my other a3 videos
I've been boosting my a3 for a year now 8 lbs and 10000 miles
Bro honestly love your shit keep it up
Thanks 🙏
I love the enthusiasm lol, time to check out the rest of the channel!
That valve shrouding hurts airflow though.(I'd rather remove that meat behind valves then have the compression)Have A3 and Z3 myself,both great engines!
wouldnt argue against it
it's good to know they are the same
I just bought a 97 EK hatch for a K build. I subbed to see what you are doing so I can replicate lol
Here in Canada I have a daily base RSX and a turboType-S.
But your right you can take a block and build it to be better than whatever u want doesn’t matter if it’s a a3 and there cheaper to get like you said so good video and keep at it
you’re my favorite dude🙌🏾
Idk, oil cooler & oil squirters are a big deal to me
im getting a k20a3 swap on my 00 ej6 & im looking to make more power, this helped a bit 🙌🏽 so if i get a2 head, crank, rods, & pistons & swap it on my a3, does the oil squirters have to do anything with the internal swap?

A lot of big shops do, they just don't openly talk.about it for whatever reason

So yeah thanks for the "insight" I guess
the question is Which one is better ..a2 a3 or z1 , z3
...........................the point is their practically the same
What if you port and polish/ dimple the a3 head for more flow lots of work but would it be worth it ?

@@VHBEngines thank you kindly haha. i guess more or less what im asking is what would be necessary to make the a2 work, are the mounts or anythng else different?
Quick question, if I put forged pistons and rods on the a3 block how much power could I make with an a2 head?
Are them the same crankshaft!? What about putting a big cam in a a3 head!?
Would you be able to make a comparison with a k20 z3 and a a2 heads? Can you shave off the z3 head to be similar to the a2?
I totally understand the phone thing I fucking hate when mine rings too!!
Can swap my 04 Tsx head for a 06 Tsx head. I want to go with my gut but I see the intake valves are different. The intake valves on the 04 are stamped with the number 5 and the 06 intake valves are stamped with the number 35 and stick out a little bit
Nice video bruh
short question sir, k20a2 or k20z3?
Asking the same, you ever find out
What’s a k24a6? I have the chance to get one but not sure on crank sizes?
this video is gold😂😂😂
I FUCKEN love this guy hahaha!!!!
Hell yeah brotherrrrr 👊😎
reccomended 87mm overbore? or stick to .5?
Have you ever put k20a2 crank rods & pistons into a k20z3 block with a2 oil pump? Can it be reved to 9000? I think the oil pump will block off the oil squirters? Thanks
Rewatch the video
Using a k20a2 piston with 86.5mm bore and polished the head of the a3 and back cut the valves :) 11.6 compression baby with boost
You don't wanna boost a high compression motor without upgrading rods and everything
Mans about to incorporate his pistons in NASAs space program lmao
bro this is hilarious lmao
Ur funny af bro haha u got me as a sub
Here is your 👍 like
A2 or Z1 thinkin bout getting a Rsx type s Don’t know what year First Car
Any K24 head is the same as a type s head just different cams. THE MORE YOU KNOW!
Type s rsx or type s tsx?
@@builtandraised type s
@@josiahbutler2254 literally didn't answer the question lol
@@builtandraised A2 head
Im looking to make 250 maybe 300 at most all motor and I plan on building myself so am I really concerned about what block i need?
if you wanna stay all motor start with an A2. the A3 has no comp, no valvetrain and the rotating assembly and the oil pump cant take high rpms. youll get it done cheaper in the end.
If you put a2 pistons in an a3, can you run a type s ecu? Or what?
Is the head an a2 head? Any bolt ons? As soon as you start modifying you should be tuning. If not you risk 💥
The oil pump is different as well
Mark Pajzer .....the oil pump is not part of the block.
Oil pump on the K20a3 out of the base RSX and the type S are the same
Ralphie May?
What is the bore size for them?
THE K20A3 IS THE SAME CASTING AS THE K20A2 WITH THE K20A3 HAVING NO VTECH BUT YPU CAN MAKE AT LEAST 20 HP WITH USING THE A3 HEAD I KNOWNFOR A FACT
what brand of connecting rod can i fit on my A3 crank?
chehsin aren’t any
VHB Engines so i’m gonna need that a2 crank huh?
A3 and a2 oil pumps are the same
The A3 that comes in the si has the fatass oil pump with the balance shafts. The A3 that comes in the rsx base has the type s pump.
Yo Chris u had live stream questions I guess u wasn't able too see them
Huh. Well shit
K24 k20 hybrid?
Whst about it
What does a real v tec head mean?
Base model k only has one cam that has vtec. And that Vtec isn’t very aggressive either.
is a k20a2 head for $500 a steal??
If is complete, no
