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

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?

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.

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?

[wesleyhitesgt]

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

[powerscape]

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?

[lapieces]

it's good to know they are the same

[patmathew]

I've been boosting my a3 for a year now 8 lbs and 10000 miles

[asdgarage]

Really helped out on my next choice for a k swap, k20a3 it is, thanks Chris 👍

[damonwarren]

What if you port and polish/ dimple the a3 head for more flow lots of work but would it be worth it ?

[MrFujack]

What’s a k24a6? I have the chance to get one but not sure on crank sizes?

[joseagonzalez]

Bro honestly love your shit keep it up

[sonofguns]

I love the enthusiasm lol, time to check out the rest of the channel!

[leechsam]

Great myth-busting video!!
My question is the following: can we learn anything from the casting codes on the block? I have seen a JDM K20, a K20A2 and now your A3 with PNC code. Is the code of any relevance to what's inside the motor? I'm trying to figure out how to select a 2nd hand stock engine to purchase.

[BigBoss_C]

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

Hey man, I need some help, I'm going to build a K203 Block with a K20Z3 cylinder head, can I use the RSX Type s ECU? My budget is low and another question, can use the engine wiring of the K20A3?
My car is an EP3 Civic Si 2003 with the K20A3.
