will i have valve clearance issue with type S (rsx) piston on the f23 motor with the f23 head?

Crono139

In theory, they should fit in like butter.

I've seen them used on an F22 without a problem.

Setup:
1996 accord wagon
2000 [F23] block
rsx-s pistons [11.7ish CR]
head ported by daveedd357 (mainly exhaust side)
iceman intake
prelude t-body [60mm]
dc headers
2.5" inch exhaust
No balance shaft belt

bump for good R&D

Same bore and compression height as F23 pistons. - they'll fit but check for valve clearance.

Uh, that's what he's asking about.

Yes I know that, but I've yet to see anyone post any info on it so I'm offering my advice, in either case he should clay the motor. What's your contribution to this post other than second guessing what I've said?

I was simply pointing out the redunancy of your post. He wasn't asking for bore and compression height. He only asked about valve clearance issues. And then you told him to check for valve clearance issues. My post was simply to make sure you don't confuse others as to what the OP was asking to begin with.

How was I "second guessing" what you said? I never questioned whether the bore and compression height were the same. If you were offended or got your panties in a twist, then I don't know what to tell you.

uhh. the whole point of the thread is to determine if there is the proper valve clearance to run the pistons, which you provided no information about, whats your contribution?

honda3x23

wow. so do they fit directly into the f22?

rsx type s pistons fit perfect in the f23 use the f23 rods nd they work put a h22 head on that bottom end . ur gonna like the power it gives u

To you and philadd - I contributed what I could. All you two are doing is critizing what I said. So where do either of you stand in this thread? As far as I know, no one has ever posted up specs if they've ever even tried the K20 pistons in the F23 block so umm yea...unless either of you know something no one else does. STFU

To the OG poster - you MIGHT have valve clearance issues. No one will know unless someone takes the plunge and measures.

Type-S pistons do not fit perfect in the F23. F23 = 86mm bore, H22's = 87mm bore and the compression height and rod length on both motors are so far off from each other you'd need custom rods and or pistons to make them work.

BlkChryKord,

Look, I'm not trying to start some childish argument over the internet. If you really feel like continuing, take it to PMs. This isn't the first time you got a little overly-excited on here...

The person in question was still talking about RSX Type S pistons...

So I guess no one has noticed the obvious. Crono139 posted a thread in which someone used RSX Type S pistons in an F23 block. (1st reply of the thread, in case you didn't see.) Although he used an F22 head, it's a good starting point. If he had issues with valve clearances, then you can pretty much assume you'll have the same issues with the F23 head. The F22 head and F23 head are pretty damn close to identical. Even though it wouldn't be definitive, it's a good place to start.

so, if i was to swap out my stock f23a1 pistons and replace them with rsx-s pistons, would i have to do anything with my ecu or my springs,retainers, or cam? i ask becuz i may be able to get ahold of some rsx-s pistons for free.

keep this thread going, very interested in the results and dyno

Yeah cuz swapping the H22 head on is so easy .

You may want to upgrade to some sort of EMS. You don't have to do anything w/ your springs/retainers or cam.

i now it aint easy gotta get couple things to do it
i was sayin use a h22 head couse coupe of peaple i nwo run that setup nd it makes great power
