alright i'm sure everyone has said something about h22 but heres the thing no one is specific enough for me. their is like 6 different engines out there for my 94 prelude si. and i'm trying to start from the ground up. my car is all stock so i thought what better place to start is w/ the engine. there are 2 JDM motors that i'm looking at(h22a: 200hp w/ 161lb torque; h22a type s:220hp w/ 163lb torque) and then i'm also looking at the h23 w/ h22 head deal. after i find the right motor then i either want to supercharge or turbo the motor that it best works w/. i need a straight up awnser. and treat it as if money wasn't an issue hahah even though it is. oh and if u couldn't tell i'm a newbie at this i'm just tired of reading for 4 days straight w/o a clear anwser for what i'm looking for( i got my damn wisdom teeth taken out so i have some time on my hands)

 

If you want to go forced induction you'd be better off with the slightly lower compression ratio of the H22a rather than the Type S motor.

H23VTEC will probably not be as reliable as either of the other two motors (not saying it cant be, but just from a practical standpoint)

 

If your gonna get a turbo, theres no reason you need to get any h22's. h23's are better for turbo charging (so i've heard) because its a bigger sized block. Also, u won't need the vtec or the higher compression provided with the h22's because u'll have a turbo, not to mention the money u'll be saving by getting a h23 instead of an h22. - peace

 

Go with the Accord R Engine from Japan...it's an H23 Vtec from the factory. DAAAYUUUUMMM

 

by the Accord R engine from Japan do u mean this one? http://www.streetimports.com/prices.htm

b/c i didn't even know ther was a factory made h23 vetc motor!
or this http://www.jdmhondaparts.com/engines.htm the euro R has 12bl of torque then the JDM H22a

H23A JDM H23A DOHC VTEC Engine/Transmission Package $3299.00

thats it. h23 vtec would be fun. kinda hard to find though. some times ebay has them. im pretty sure all the h22 parts are interchangable as well, so if your missing axles or anything... just look h22.

 

so u think i should go w/ that huh. just wondering what the difference between the JDM H23A DOHC Vtec
JDM TYPE S H22A
and y rn't guys putting these motors in their cars? cause it seems that everyone is putting in the JDM H22A W/ 200hp?

 

jdm wont pass smog. thats why i went with usdm. the h23 is an accord motor. it bolts right in, but ive heard things about this more. ALOT of wiring issues, since the prelude and the accord are totally different cars.

 

ok what r u saying? what u just said is saying i shouldn't get a JDM and i shouldn't get the euro R b/c wiring problems? so then what motor should i get hahahah?

 

you asked why i passed over the jdm and the euro. thats the reason. if you have the time and money swap for the bigger motor. i would choose the euro personally, but like i said... only if you have the time and money.

here in southern cali. there are strict smog laws, and really **** cops. i try to stay away from anything that would make a cop think im not smog legal. ie: bright colors in the engine bay, I/H/E, forced induction.
but, if you dont have to worry about that ****... go with the euro. spend the money and do it right though.

 

ahhhhh i see ok well yeah smog i dont think is a prob. in Columbus Ohio. good point. do u really think i would run into wiring prob. though :/

JDM TYPE S H22A</TD></TR></TABLE>

The H23A Vtec is 200 PS and the H22A type s is 220 PS

 

im sure you would run into wiring problems with the h23. then again, why dont you make some phone cvalls and ask someone who knows for sure.
just go with the h22a type s. that settles all you questions right?

 

yeah thats what i'm think and the type s is ATTS which makes it so i cant boost it or something like that so now i'm looking at the Sir S Spec check it out http://www.preludeperformance....id=37
its the same as the type S only it doesn't have ATTS and it has 4WS which might become a problem i dont know but what i need to find out now is since its a 5th gen motor will it fit my 4th gen? if is does then i'm set!

 

you have a 4th gen right?
the problem with using 5th gen is that they are all obd 2. the 4ws wont be of any use unless your car is equiped with it. same with atts. the atts system wont work unless your car has it.

 

ok cool, i thought that might be a problem. than man for all the info. i'm prob just gonna get a JDM h22a and mod the badboy up, i've been hearin its a pretty sweet **** motor to mad up and can handle boostin pretty good

 

i got one.... i love it. i would swap for any h22a all over again.
you probably wont be dissapointed.

 

yeap, just grab a cheap JDM H22A (non type-s) because if you really want to run FI you're going to change the internals anyhow. So why spend for the Type S internals?

 

what car are you going to put this engine in?

 

i'm gonna put it in my 94 lude si all stock right now, once i get money

 

If you wanna really boost you have to sleeve and build, prelude stock pistons can't handle it.

If you have an H23 now why don't you just save the money you would spend on the other engine and just have the block sleeved and put in your turbo pistons and the like, and do the turbo head work etc...probably cost the same and the bottom and top end are ready to go.

 

well wouldn't i get more power out of a JDM H22a then my h23? and if i would have to switch pistons couldn't i use the h23? see i'm new to all this and i'm tryingt to find out whats "best" just not whats the cheapest. as of right now i have a stock h23 so which do u think can make more power swaping an JDM H22a and going from there or stickin w/ my non-vtec 160hp motor?

 

depends... for $5000 you could either build up your existing H23 plus purchase the turbo kit, *OR* you could buy a JDM H22 and have cash to get a turbo kit w/o redoing the internals. And in those two situations the H23 would be able to handle alot more boost, equaling more power.

Granted that $5000 is sorta just a random number with you doing all the the labor etc.

 

Hrmmm, money and more money and more money, OMG it will never stop but boost is the way to go. Get yourself a Euro-R or JDM with LSD to help you hold the road and have the block sleeved, get forged everything, portflow port N polish with portflow or ferrea valvetrain, big *** injectors, big *** intank fuel pump, custom turbo kit and most importantly get some kind of engine management and have it tuned properly. don't get a type-s cause it comes with atts which will cause other probs later. this will get you started and then you can replace the other things as they break. good luck.
