yes it does
FRM can cause serious oil consumption problems down the road.
i think this is more of an issue compared to blowing a ring land, or the actual FRM sleeve.

YOU said a f22b was basically a h23a1 internal wise...meaning it cant support more boost than an h22a. since h22a and h23a1 have similiar internals.
the only difference like you said is "the FRM lining" and the bore
so you base your f22b argument around the FRM?
:eh:

like i said, there are several stock block FRM h22a turbos making excellent power.

you also forget that i stated "stock"
if you want to talk about building a motor for turbo...then the h22a will whoop the f22b, psi for psi any day of the week.

h22a = higher revs, more lift in vtec, better balanced assembly.
better engine overall

also...NEWSFLASH, the rods/pistons, are the main weak point for these engines when dealing with max safe boost level...
NOT FRM

~boom

 

lets see...as far as an engine swap goes, I would save up your money and go for an H22, it really is worth it. When I blew my h23, the guys I was ordering through suggested I go for the f22b, since it was a direct replacement for the h23, and slightly less than the h22. But since I'm stubborn, I went ahead and paid 1500 shipped for an h22, and used my h23 tranny.
BigLew, your saying that since the F22 doesnt have FRM, it has a stronger bottom end...yet, if you had your choice, you'd boost an h23 over the f22, right? Well, all that aside, I think what boomer is trying to convey to you is this...Pound for pound, a boosted H22 will whoop a boosted F22 or H23 anyday...not about reliabilty issues or anything else, but simply that the H22 is a faster boosted engine. (boom, correct me if i misunderstood you )

 

Man are you a total noob or what? I have respect for most of the things I have seen you post in this forum but you are totally clueless as to what you are talking avout here. The oil consumption has NOTHING TO DO WITH FRM. H pistons are notorious for weak ringlands that is reason for oil consumption not the sleeves.

F22B Has a steel bore. People who run high boost succesfully on H series get aftermarket sleeves and forged pistons to withstand higher boost. The after market sleeves are for the forged pistons. Since F22B has a steel bore there is not the need to replace with aftermarket sleeves. Have you ever seen what aftermarket forged pistons do to FRM sleeves??? Obviouslt not or we wouldn't be having this conversation.

I never said that the H22A will not make more power at the same boost. But it is a fact that stock H22A's will not hold more than 6 psi for very long. It is well known with anyone who doesn't have thier head up thier ass about forced induction that lower compression engines make for better boost. Why? Because there is less chance for detonation.

I also never said H22A is not a better engine, I have 2 H22s.

NEWSFLASH replaceing with forged pistons jacks up FRM sleeves, so YES FRM.

 

Again I NEVER SAID H22 WAS NOT BETTER I HAVE 2. I was stating facts about boosting and weaknesses of the engines PERIOD. And given the choice I would rather boost an F22B, I would rather not pay $1400 to sleeve an H23. For the record I have an H22A under build process for JRSC, for 4th gen Prelude which I plan to run at 10 psi and YES I AM SLEEVING.

 

the f22b does not necessarily have a stronger bottom end simply because it doesnt implement FRM.
the stock rods and pistons should be a concern

yes forged pistons will destroy the FRM liners. however in that respect we are talking about a built motor since you are changing pistons. and why would you only change the pistons? you wouldnt, you would do rods/pistons/sleeves.

so yes you are saying that the only advantage of the f22b is the cylinder walls. i can agree with that. but that doesnt necessarily mean the engine can handle more boost than an h22a, because the f22b internals are no better than h22a internals. that is my argument.

and there are *stock* h22a's running over 6psi reliably.

~boom

 

If you already have steel sleeves then there is no reason to change sleeves, just rods/pistons.

You are still wrong about H22 being able to "handle" more boost, it's a FACT boost is easier on lower compression. As far as which one makes more power, of course the H22 does I never argued that. Just cause it is the most powerful does not mean it is the most sturdy.

As far whomoever you know that run stock ludes over 6 psi daily, I know one guy that lasted a year on stock H22 before his ringlands went every other account I have ever heard have problems sooner. All those guys have heard of others running over 6 daily reliably too until thier ringlands went.

 

corky bell says that lowering compression is for pussies.

u realize that a low compression block with the same boost level as a high compression block, holding both displacements even...the high compression block will make more power.

when i stated rods/pistons/sleeves i was referencing the h22a motor.
i think it has been posted several time's now that the f22b has steel cylinder lining.

as far as sturdy. i guess u dont think 8500-9000 on stock block is sturdy huh. of course i wouldnt trust my h22a head to handle that RPM, but we are talking about blocks.

~boom

 

Reading comprehension big fat ZERO.
Well you didn't clarify that in your post now did you?As you can see you said in a built motor you change rods/pistons/sleeves without mentioning the H22A and this rebuttal was in to my statement of why you do not need to change sleeves on the F22B.

You are completely changing the topic now, we were first talking about the cylinders being able to handle forged internals for higher boost and now you are talking about revving limitations which is crank strength. Which you wouldn't care about on a boosted engine anyway.

 

1. - how many times are you gonna say that the f22b has steel lining

2. - im not changing the topic you said it wasnt sturdy bitch. I think its pretty obivous that rods/pistons/sleeves categorize a block build for the h22a, and subtract the sleeves for the f22b. how much more are you going to repeat yourself about this stuff guy?

3. - reving limitations are more likely to be based on the head, since that is what will break first. i mentioned that before, but now your talking about "crank strength" which doesnt mean much about longevity of the block in general. i spun a rod bearing on my h23a1, not a main bearing, and the crank was only a little chewed. it may have been a flawed crank but it made it to 150k.

 

Hey asswipe how many times are you gonna say absolutely dumb misinformed bullshit based completely on bench racing.
Again, you need learn how to READ, go back and read my very first post I specifically stated I was talking about FRM sleeves. Read it over and over until you get it and if that doesn't help go get hooked on phonics. As far as me being a bitch, that's not what your mom said. You little punk know nothing ricer. OOH look your not the only one that can flame.

So you are discounting the crank then huh? So what are you talking about then? The strength of the bare block? The bare blocks of an H23 and H22 are the exact same numnuts.
