My plan was to do a k24/k20 frankie but my question is what would be the best k24 bottom end to use? Would it even matter since the head would be changed? or would it just be wise to stick with the k24a2 top end since i have one sourced? i want to make sure i keep true vtec and the car is for street/road track use.

Best K24 block to use for that swap would be the K24A2 TSX block. Stronger internals allow it to handle more power with fewer mods than other K24 blocks. And about the K24A2 head, I'd say it depends on price vs power gain. A good K20 head, either Z1 or Z3, will net you more power and torque than a K24A2 head, but the K20 head will most likely be more expensive than the K24 head. All three cylinder heads mentioned have true i-VTEC, so you'll keep that no matter which head you choose.

if you just want to drop it in and not mess with internals, the k24a2 would be the best option.

if you're doing a complete build and replacing internals, the cheapest, cleanest condition k24 block is the way to go.

Why would one do a k20/k24 swap? Does the K24 have a stronger block than the k20 or something?

The 2.4L shortblock is larger, i think the answer is obvious, as well it's capablilities of making more power. It's no secret

I had it backwards, for some reason I thought a k24 head on a k20 bottom smh. But i dont know anybody that has a set up like this so I don't really know much about these swaps.

Ok so im taking an engine building class at school and wanted to assemble a k24 shortblock: K24a4 block, 04-05 tsx rods, and 09 tsx pistons.

So basically my question is.....Are ALL tsx rods and ALL tsx pistons compatible as far a wrist pin diameter goes? without milling the small end or anything like that? I know about valve clearance being tighter with older tsx pistons but aside from that will this work?

04-05 tsx pistons with 04 tsx pistons attached, I would like to change them to 09 tsx pistons. That's the plan.

I just built this:
K24 (Element block, not the K24a4 TSX block with piston squirters.)
K20a2 head
Wiseco 12.5:1
Scat Rods
PRB Intake with hondata spacer
DC 4-1
AEM CAI
KPro
And more but thats the basic picture for now.
After initial break in the head was pulled off for a complete build.

I would go with the accords or crvs k24s. Accord would be like an american tsx.

Hey guys, sorry to bring this back but my brother has been in the process of piecing together a k24a2 with a cammed k20z1 head and the mechanic was worried about the clearance between the valves and Pistons. The k24 is completely stock except for a z1 oil pump. The cams he's using are the S2 turbo cams, I forget which stage. Thank you for the help
