h22a turbo question

[psycobone]

do i need to change my stock internal to go turbo or can i go turbo whitout changing my internals on a h22a? low boost or high boost

thanks

You need to do more research. H22A are tricky.

[dean_harryman]

Low boost will be ok on stock internals, I personally wouldn't go over 6 psi 8 is pushing it. You have to realize that the h22 is rather high compression, and with forced induction you are raising the compression even higher, which can lead to pinging, so running on premium is a definite must!

If you build the block up, you can go higher psi, but why go through all that when your f22a block is already sleeved and has eight to one compression? Just put the h22 head on the f22 block, and turbo the pis out of it, it it blows, go to a junk yard and get another block.

Just my .02

LOL nail, we where posting at the same time, I just took longer than you! LOL

[psycobone]

ye but even if i changed the block it won't put the compression down the head is still the same.what if i put a spacer that should help?

[dean_harryman]

Yes, if you change the block, you will lower the compression.

[psycobone]

ok.in that case it's better if i put the block of a h23 the compression is 8:1 non? and is a 2.3L

[NAiL05]

YOu can lower compression in multiple ways...Flat top pistons, thicker HG, theres a lot you can do to lower compression rather than just changing the whole block.

all the info that is either written out or in warings for the average honda person is not fake, there have been many question answeres theories either crushed proven or tossed in a pigeon hole. Ranting or not there is so much info on hondas that if some one couldnt read long enough to learn their wallets and bank accounts should be depleted. Oh to answer your post, h22 have sleeves that are made of some fibre. a piston company makes a PISTON that fits in THAT sleeve mad of the SAME FIbre. so go search.

what the eziest and the fastest way?

[dean_harryman]

I was figuring he wanted to swap in an h22a, but I was assuming, if he already has an h22, then yea, there are other ways to lower compression, but if he is going to buy an h22 then just buy the head, you know what I mean?

I guess the h23 block would be good, but, the reason to go f22 is not just for the low compression, but alos for the strength of the block, and it is already sleeved, which is something you should do to a boosted h22....

to each his own, I like frank motors, so a g22 is the ultimate in my book....

a turbo doesn't raise compression, at least not the compression you're speaking of.

The "high compression" you referred to is static compression. This can only be changed by increasing or decreasing the combustion chamber volume.

Adding a turbo does not increase the chamber's volume.

Now, dynamic compression, that's different.

Either way. There's nothing wrong with boosting an h22.

The key is getting it tuned properly, and maintaining it properly.

the f22 is not "sleeved". It does come with iron sleeves tho. H22/h23 come with FRM sleeves.

[dean_harryman]

All I am saying is that if you have 2 engines, one is 8.8 to one compression, and one is 10.5 to one compression, and you put 20 pounds of boost to both on stock internals, which one do you think is going to blow first?

Also, I can go to the junk yard and get an f22 block for a couple hundred bucks, an h22 is WAY more than that.

You asked what is the easiest and fastest way.

If you have an h22 in your car, boost it.

If you want to put an h22 in your car, just get the head. put it on an f22 block, cheaper, "Lower compression", and you have an f22 bock already. one less thing to buy!

Quoted form an acura tsx forum...

"I have owned every vehicle that has had an engine with FRM cylinders (S2000, Prelude, NSX) and i can tell you from experience that the drawbacks far outweigh the benefits. You cant bore/hone the cylinder, or boost it over about 7psi without sleeving it. They wear out much quicker when used in racing applications. FRM sleeves were originally created for formula 1 use, in which the engine is only used for one race. So what if the cylinder walls are glazed over after one race? Team honda surely can afford a new block. In street cars, the engines need to be able to go 100's of thousands of miles, and with the FRM sleeves, the cylinder walls are thin and soft under the thin layer of chromoly that lines the cylinder."

*END RANT, I am done talking about anything to do with forced induction, to many opinions.....

P.S. you have to change over some pulleys and stuff to put the h22 head on the f22 block, there is alot of info about the swap floating around the forum.

rant about what?

Don't be mad because you were corrected on a few things you said. It wasn't a personal attack(that's what I'm e-sensing from you)

FRM is fine. Even for boost.

I said what I said, and I will stand by it. So, to answer your first question "All I am saying is that if you have 2 engines, one is 8.8 to one compression, and one is 10.5 to one compression, and you put 20 pounds of boost to both on stock internals, which one do you think is going to blow first?"

The engine that is least healthiest and has the worse tune will go first.

For the record, 10.5:1 is far from high compression. Maybe for a stock engine, but for anyone that's into building/tuning motors, 10.5 is not high. Not like you make it sound anyways.
