K Series Base Model: Why You Should Be Buying These Heads

He’s back. All what you said is true 100

The 2nd gen crv heads aka ppa or ppl stamped head. Is the best flowing k series head. Kyle from boostedboiz uses it. Prayoonto on their 1200hp+ k series engines. It out flows even the prb type s heads and tsx. 4piston loves that head and they can port it to the max. I have a stock ppa head on my k24a2 engine. Stock port those heads can produce over 1000hp easy. I got my ppa at my local junkyard for $80.

I got an 03 accord for free. Swapped the entire bit into my CRX (88). Just the swap made it damn quick.

Doing a K24A4 build with Nippon racing 11:1 pistons, scat H-beam rods and TSX type S cams Vtec locked. Porting the heads as well. Here goes nothin.

Hey man, I'm trying to find stuff on rl5 pistons with no luck. Do you know if they would work with a k24a4 head since they have the similar piston bumps? And how would this work with k20a2 cams?

[mitchlehmann]

what do you know about the k20z2 stock bottom end?

[kylem]

I know the K20a3 can make some power with a vtec killer setup, and pistons/rods and even an a2 crank/oil pump and valve springs are not that cheap.

I’m just not that sure if it’s a lot cheaper than a k24a2.

I have a base RSX as an extra car (rarely driven) that I’m considering building to make it a more fun run about.

So if I go the vtec killer route, cams/rockers/springs will run ~$750. That’s decent. But a whole K24a2 for $1300 with a slightly higher compression ratio.

And if a person needs to source an a3 head for a block they have already, it’s nearly the same cost.

I don’t see how it’s cheaper. It’s still a cool budget build with potential. Is there something I’m missing?

So if I end up building the RSX, the K24a2 seems like the better choice. Similar cost with 20+ hp and more torque.

I end up with a spare a3 long block that might make a good basis for a build/swap into a classic euro… Or it can be parted out.

I have been telling people that the vtec heads are way overrated for years. I would rather have something more consistent and reliable. Look at when people blow up their vtec engines. It usually happens when vtec kicks in and they get the surge of power and torque. It's probably a tuning issue, but either way, having a nice smooth power and torque curve makes tuning easier, more reliable, and consistent.

I just found your channel, and am going to do some more watching, but I have a question.

I have an 06 RSX base, everything I've read basically says to sale it and buy a Type S, but I'm not built that way.

Going by what I know about forced induction builds, and from this video I think I'm on the right path.

Would something like this work for 3-350whp?

SBE, TSX Cams/VTec Killer, RBC Intake, something like a MHI 16G, E85, clutch, and KPro?

Rsx is still expensive but that Accord shit is plentiful

Got k24a1 head with the valves from that head and using 08 tsx valve springs package

Do I use crv k24a1 retainers and keepers cause of the valves or should I use seats, retainers and keepers from 08 tsx ?

My question is can you do anything with an a3 block if you send it to the machine shop to get it to similar specs to an A2, Z1, Or Z3? I have a spare k20a3 motor that i want to do something cool with. Plenty of Z3 heads around my area for pretty reasonable price.

[timscheuermann]

im throwing a A2 head on my a3 block. I got a set of z3 pistons would those be worth using?
