i was thinking of getting a tsx motor then i thought to myself couldnt i just replace the head to a k24a2 and it would be a tsx motor? someone correct me pls if im wrong.


i asked my friend if i should go k24/k20. he told me i should just get a k24a2 instead. which i think would be ok since im probably going to swap into a 6spd later on anyways.

valve to piston clearance Andy. At the very least you need the tsx pistons. BTW did you place the order for me?

What he said. From what I've read over on k20a.org, you could slap the k20 head on and at the very least swap over to TSX pistons. There's another set of pistons from a k you could use that cost less than the TSX pistons and solve the piston to valve clearance but I can't remember which ones they are. I believe it was the k24a3 pistons out of a CRV but don't quote me on that. Not to mention you'd need some sort of engine management :cough:kpro:cough: to ensure your engine runs properly after the swap. There's a wealth of information on k20a.org for you to read up on.

not k24a3 but k24a1 pistons would work but you should get the 09 tsx pistons, they have 11.1 compression

That's what it was. Thank you Dave. I knew it was one of those. I completely forgot about the 09 TSX pistons. I had read about those as well. Good call dude.

What are your goals and plans with the motor?  When it comes down to it, if you're planning on building a motor (bottom end and head) then build the K24/K20.  If you're just looking for more power than what your K24A4 has, then swapping the entire motor will probably take less time and cost less.  You may want to try and get a hold of an 06-08 K24A2 since the top end has been upgraded to flow better.

thanks tim. i would need the tsx ecu as well?

No, run Kpro instead

Yeah, kpro is going to be the best option.  You can run other ECU set ups, but kpro is the best option if you want to make power.

ok so i got eibach valve springs. they dont make them for accords. but they do for tsx and rsx. same fitment right? if not then imma just get a k20 head and start from there.

i got them from a raffle off at a car show. just in case you guys were wondering. nice come up =)

well.. it depends on what cams your planning to run.. different cam manufactures have different specs and suggest different valve springs. if your getting a stock tsx engine and dont plan to work on it, then forget the springs, probably dont need the aftermarket springs and the labor to install it just wont be worth it.

and springs arent worth that much, i dont suggest deciding what to get in terms of engine or head based on a set of springs you got for free. the above should be determined from the goals you have in mind.

+1, sell them on ebay and use the money for other mods

If you decided to build an engine at all I suggest Kpro Andy. That should hold you over for a few months while you decide what route your going to take. You cant run the Frank w/o engine management.

yeah. i was thinking about that. but i kinda want my 6spd before kpro...

im just very undecisive right now. ill figure something out. everything is popping up with $$ problems

you can use F22 pistons out of a S2000 and use tsx rodes 11.1 compretion and they are cheep than 09 tsx pistons, you dont want to run anything on stock k24a4 pistons they are thin. and the reason you can use any of the k24 series pistons exept k24a2 (tsx) pistons is because
the tsx pistons have valve releafs and the rest dont, its kinda the oppesset. and if you are going to swap the head ur going to need a k20a2 oil pump,chain,tentioner.

no need to press the submit button multiple times. haha.

the s200 pistons and tsx rods are not a perfect combo, the tsx rods would need to be machined to properly fit with the s2000 pistons and even though the pistons have 11.1 compression, that wont be the case when used in a k block.

keep it simple and use tsx pistons and mil the head to raise compression, just make sure you dont have valve to piston contact.

yea but all you have to do to make them fit together is to mill a little off the top of the tsx rods. all you have to do is weigh and balance the rod. but one of the clutch masters cars used to run f20 pistons and made 13.2.1 compretion.
but milling the head is not keeping it simple thats just as hard to get done or harder.

i spent numerous hours reading on k20 before coming to decision on how i was going to plan my build. any combination of parts is going to require some form of custom work its just a matter of what is easiest and most reliable. i believe that using all k parts will be more reliable than mixing different parts from different series of engines.

i have too. if f20 pistons work and work great in a k24 motor and f22 pistons fit and work it shouldnt be a problem. it is a little bit of work. but should be fine. im not saying for this guy to do it, it was an idea. but im doing it. but why is it unreliable to use other parts from something else that may work. there is a guy on there that is goin to use k20 pistons in a j series. you can mix and match parts and work great or better the others.

i just have the belief that it is not as reliable, but to each his own.

I'd just use aftermarket pistons to get the compression ratio you want.  OEM parts are good, but you have more options when you start looking at aftermarket parts.

I know this is an old post, but I just caught this as I was reading through the thread again.  This information is not entirely correct.  You definitely do not need the K20 oil pump.  It is however a good suggestion if you're planning on raising the redline.

How good of you to realize you're bringing this thread back from the dead Tim.  :D

That's how I roll.
