How about you just get a block saver? What will happen if you don't get new sleeve's? I'm lowering my compression ratio so I don''t think I need to resleeve.

 

you don't have to resleeve the block unless you are boring it out and putting in larger pistons.

 

the reason for resleeving is for the ability to run forged pistons.

If you want to run any type of forged piston, on stock bore size or larger, then you have to resleeve it.

Why, you may ask? The stock H22A sleeves are lined with what is called "FRM." It's a composite material that doesn't mix well with aluminum and friction. After several thousand miles it starts to glue up, and it will lock up your motor. Not pretty.

 

Is there anything else I can do besides resleeving the block? it seems like that's madd money to run forged pistons.

 

NO not if your running forged pistons to do block work it should cost you about 1000 for resleeving the block save your self the trouble and do it right the first time
or you will pay alot of $$$$$$$$$$$$$$$$ in the long run.

 

Actually I talked to Importbuilders.com and EIP tuning and they said it was not necessary to resleeve for forged pistons. They both have run setups that still currently work for them with no problems. I've been told you can hone it a little and still be fine for forged pistons. Nevertheless, I still think i'm going to resleeve just to be safe. So it is more or less, your call whether you do it or not. Besides sleeving will be a little more stronger and reliable.

 

If you guys need your blocks sleeved, let me know. I can get a deal at Golden Eagle. If you need references, I just ran an extremely successful GB in the forced induction section. For an H22 the price for the sleeves and shipping to and from GE is $790, add $125 for a bore and hone. You will have to cover shipping to and from me.

 

Is there anyone that is running forged pistons on a Non-Resleeved H22a engine? If so have you had any problems. Becasue alot of shops are telling me how I don't have to resleeve my engine to run forged pistons.

 

todd already explained this once to you

 

You won't find them running. At least not after a few thousand miles.

Talk to member 2point6. He can tell you first hand of the results.

Then you need to stay away from these shops. If you don't want to take my word for it, then don't. I've only been playing with H22A's exclusively for three years.

The H22A runs a sleeve that has an FRM coating. This is supposedly the same coating that the NSX runs. None of the other Honda/Acura motors like the B series, or D series or even F series uses this type of sleeve. Thats probably why these little shops of yours think they can get away with running forged pistons.

 

the s2000 block also uses these cylinders. some people just never listen, let them find out the hard way.

 

So why did they use this FRM coated sleeve anyway? Is it better somehow?

 

From what i understan,these frm sleeves(not coating) were made to be able to run bigger sleeves closer together in a smaller block...more compactness,less weight.The sleeves are primarily made of aluminum,hence the reason the h22a pistons have an special iron-base coating.now if we did run an aluminum forged piston on an aluminum sleeve.aluminum rubbing together is not good.Creates alot of friction,heat,and they will eventually melt themselves together.if anyone has actually done this,id like them to join in this thread and explain how they did it.This link on how the nsx block is made also explains the concept also.

Ah so resleeving and forged pistons will add a fair bit of weight to your engine? How much approximately?

 

not enough to make a big difference.

 

Todd, you mentioned that the F series doesn't use the coating. I've got another project for me f22 that's sitting in the garage. is it possible to get forged pistons as well as put a vtec head on the f22 block??

h22 head on a f22? can you even go from a sohc to a dohc conversion? get a real h22a.

 

I"ve got an h22a. Did the switch to my lude. but now I've got this old enginge sitting in my garage

 

whenever i called JE and asked about their pistons, the guy told me that a stock H22 would not handle their pistons, and that the block MUST be resleeved in oreder to run their pistons. one of my frineds said "they only told you that so you'd buy their re-sleeve kit" but then i told him that they didn't sell a re-sleeve kit (moron) and he was just like "oh"

 

Not even possible. I think he meant an SOHC VTEC head on the F22...

Yes that's easily possible.

 

oh i was about to say the h22a head wont even fit on the f22 block

 

I did mean a SOHc. the f22 is sitting in the garage. I already have h22 swapped into my car. just wanted to have a little fun w/ the good old accord engine. maybe throw in a geo prizm for fun.

 

your talking like a franky motor
right

just adding the vtec head on top of the nonvtec block on your f22?

hmm check the accord forum . i think many have discussed it. but they all come up with the fact that it wont run proper..

 

edit- wtf did this come from?

Aren't people now trying to make s2k engines with a f22a block a different crank and top? Thought I heard something like that....or maybe that was making a stroker kit... *ramble on*
