Well right now I have two choices in mind.

1.) Save up and buy an H22 and keep it N/A for a while and have a few mods on it (I/H/E)

2.) Build up my H23 so it will be able to sustain a turbo.

What are the pro's and con's of these two?

My H23 has 115k on it, but had some headwork done at 90k, its strong.

Im guessing that they will both cost around the same, but just incase im wrong..

What would have to be done to build the engine up for a turbo?


thanks!

to do a proper build up for a turbo would be putting in iron sleeves, forged pistons and rods and balance the crank ...

as well, replace all seals and consider keeping the balance belts or not ..

My opinion, if your happy with the h23 but want more power .. a mediocore turbo kit could do you for a while, OR get an F22b2 block (stock iron sleeves but smaller bore) otherwise same as H23 .. you can runa turbo on that, blow a piston ring .. get some F22b2 forged pistons .. no sleeving necessary .. the f22b2 blocks come cheap too ... 200bux at MOST ... people get em from the yards lately for 50bux and up ...

Or, just build the H23 n/a . get some cams, fuel management and spend lots of time on the dyno . .somebody was putting out 190whp with an H23 ..


really it depends what you want, usable low end power (h23) or high end revving (h22)

no $hit, I didn't know the f22b2 had iron sleeves.

now that we are tlaking about the f22b....

what did the f22b2 come from.. and does the regular f22b come with the iron sleeves also or does it come with that carbon stuff that the h-series comes with

Accord.. not sure what year .. 94-97 .. go read the thread in prelude section on h-t .. its awesome, so so so so so much information

correct me if i'm wrong.. but i just saw pictures of the engine on h-t and it seems to be the same thing in the s-model prelude

i thought that the engine was goign to be a dif version of the f22b or jap spec h23

reason i ask is cause i have an f22b running in one of my ludes right now

yeah, isn't the engine out of the 94-97 Accord/Prelude S the F22a?

maybe the code for the prelude s-model is f22a and for the accord it is f22b2

so i guess i won't be throwing fordged slugs into my f22b afterall

oh.. to the person who wrote this post.. there's a very long (44 pages) worth of turbo prelude info on h-t.com i read the thing for like 30 minutes and stopped

i'll post the link once i get home..at work now

either way you go.. make sure it's what you want from the beginning.. becuase changing your mind later on is very very costly.. especially when you start building up the turbo and the engine and then decide to do something else

thanks alot so far ya'll

i'd love to have some good power from a turbo, but money dictates all in my life.


so you think if i built up a n/a h23 that has currently 115k miles on it i could get another year or two out of it? (i don't dick around much at all)

i mean, there aren't alot of dyno shops around me so i dunno how much time i could spend on one.

maybe do up the engine n/a stylee and add some nos? like a 50-75shot? not sure what kit though..i'd like a fogger system, but its more cash.

here's teh link

http://www.honda-tech.com/zerothread?id=316373&page=18

so anywho.. i wouldn't touch the engine if nothing is wrong with it.. maybe if you haven't done regular maintainance... i would do the water pump, timing belt, tensioners, balance shaft belt.. then do a valve adjustmant after that's done.. to make sure the fuel system is up to par.. send the injectors out to cruising performance (http://www.cruzinperformance.com/fuelinj.html) replace the fuel filter and as far as ignition goes.. replace cap and rotor, plug wires and plugs

if nothing else.. it should net you another 50-75k on the motor and you may gain some ponies... figure you lose little by little each year driving the car.. all this maintainance can gain back some of what was lost

ok, not F22A .. F22B2 .. there are some F22B5 or F22b? blocks that dont have iron sleeves, B2 does for sure ... there are some other things u need to do but its not SOHC ... the H23 head will bolt right onto the F22B2 block with all proper oil passages etc.

There might be some other type of parts u need but you've got the H23 so it doesn't matter .. u got everything u need ... maybe just do a custom gasket since the bore is smaller and you dont want bits of your head gasket getting burnt up and sucked through the cylinders etc..

Honestly, I think this is the best cost effective boost .. since your talking about 2 years use .. keep the bottom end of your H23 around in case it does go ... if I had the time/resources I'd be doing this already .. honda cars are rare enough, but if I could get an F22b2 block w/ iron sleeve for cheap .. i would not have bought my H22.

Thanks for the threads tenzola!

Well I do like the sound of just completely updating my engine with a lot of regular maintenance. But in the process I’d like to gain as much power as I can. So maybe go that path and get some cam gears/ cam shafts/ some other internals to grab some HP out of the whole process.

But I will look around for an F22b2 block, b/c that would be a lot of fun to do. This only being the case if there wasn't too much to it as far as customizing **** goes.

Keep this thread pumping though...I’ve learned a lot so far

just search the pages of po.com for engine rebuild or h23 or f22b

i know i learned a lot from people who have writen abou their experiances in the past

any project really comes down to money...

i've done a h23 -> f22b engine swap on my 92' si
rebuilt an h23 and took out the balance shaft on my 92' si 4ws
and i just drive my 01' with the h22 and bolt ons

so far to date.. the rebuild cost a lot more then buying an engine and throwing it in.. plus the cost of sleeving and fordged slugs and rods was goign to burn a very big hole in my wallet.. i decided just for learning experiance to build it to stock spec.. but if i had to do it over.. i don't think i would ever re-build a honda engine to stock spec again.. so much cheaper and simpler to do an engine swap.. even if it is the same engine.. or a similar jap spec one

=)

but hey.. everybody has differant goals.. just gotta figure out what yours is...

oh.. if you want turbo.. i'm working on the h23 bone yard boost project using parts from the eclipse.. you can do a search on that and find a lot of info.. once again.. money has left me high and dry and i won't be completing this project till spring sometime

but read up on it.. very good info from all members
