The K24A1 Rod is not only thinner/smaller it will not fit the TSX wristpin if I recall correctly. The weak point of the K24's and really any K-series rotating assembly IMO is not the rods themselves but the rod BOLTS as they're pretty small and the rod/piston combo weighs a good deal. That's just my personal opinion, however.

There are a few things I have to add for the CRV rods, however.
-They have seen 32psi on the Dyno/Street and survived. They did however blow up at 42psi... (Onyx, User BoostedGSR-Si)
-I have personally been to 7500rpm and beyond on a 100% stock CRV bottom end
-I am currently running 12psi on a Comptech S/C, still revving to 7500 rpm which is 1000rpm over stock redline.
-I have run for 20k+ on a 100% stock CRV bottom end, driving it every day beating it to hell and back. I drive this car like a rental. Still going strong.

i agree 100percent. many ppl rev the shit out of the a3s almost to 9k daily and one person actually tore apart his motor anyways bc he was switching to a2 bottom end parts and confirmed everythiing was okay..he had pics up too.

i would just replace the rod bolts to ARP and call it a day..

 

Here is a pic of the K24A4 rod(same as A1 rod for the most part) and a TSX rod

And here is the K24A1 vrs a Ultralight rod and Wiseco piston.

 

Thanks guys. I've been wondering why so many people run the CRV rods (and pistons) when everyone says not to use the Accord/Element ones. But it makes more sense to just replace the rods too in the Accord/Element blocks because of the valve clearance issues.

I'm too broke for a SC/turbo right now so I opted to go higher CR on my K24A1 (with K20A2 head). I feel better about buying the used TSX pistons and rods now. I just needed to justify it. Heh.

I know I should get new piston rings and rod bearings but would it be harmful to reuse the same bearings if I put them back to their original crank journals, but just with the TSX rods instead?

 

rod bearings have to be matched to the crank. If your using different honda rods.. you have to match the number and letter up to find the right size bearing.

 

My understanding was that accord/crv/element all have the same rod part #.

 

I run tsx rods with cp pistons on them and have been beating the shit out of it since Febuary and have over 20,000 on them and lots of track time and havent had any issues. I also rev it to 8400, and im sure thats well over factory redline.

 

Very impressed with your numbers for an RSX-S. A little more detail on the setup would be interesting.

 

so will the tsx pistons fit accord/crv/element rods?a def answer would be great...

 

Yes.....there was a post in this section.
The guy put 2009 Tsx Pistons on Accord rods...with no problem!!

The answer is yes, my buddy works at the local honda dealer. The rod part#'s are all the same. The only changes inbetween the 3 different motors would be in the piston and wristpin part#'s. Like I said the rod part# are all the same on the accord/crv/element.

Josh if you come up on CRV pistons, let me know.

sorry to bump a year old thread but i figure its on topic so its better than making a new thread...

so i want to take this discussion i little further. i have a k24a1 block, i have 2009 tsx pistons. im looking to pickup some tsx rods. has anyone had a chance to physically compare a 06-08 tsx rod to a 2009 tsx rod? i know they have different part numbers(and a hefty price difference too) but i was curious as to how similar/different they are from one another. is one beefier/stronger than the other? if anyone has any info id LOVE to hear it. im in the middle of searching up on this topic so if i find anything i will post it up in case anyone else is wondering the same.

thanks in advance to anyone who can help out!! :up:

 

Some one plz answer his question (^^^^) I also need to know.. I'm planing on using 09 tsx pistons with tsx rods on my k24a1 but I dont know wat year tsx rods to use without any modification done to the rods..

 

TSX pistons with TSX rods should require no modification as far as I know.

 

Scourge I am going to quote this and laugh, lolz

 

Thanks this thread has been very useful to me

 

is it eazier to just use tsx rods and pistons out of an 06 and throw an a2 head and oil pump?would the 09 tsx pistons in a a1 2.4 have a higher compression with an a2 head,and what about valve clearance?
