jdm h23a into a civic?
 

i wonder have any of u guys have a H23a (blue valve cover) turbo in a 92-95 civic hatch before? right now i have a H23a coming from Japan and i just bought a 94 accord with a blown engine. i'm thinking should i put the H23a in the accord or maybe i should go get a civic and put the H23a into the civic. for sure i will turbo the H23a. (8 psi). would the H23a turbo be too strong for the civic? or should i just put it in the accord dx? give me some opion. i think H23a is in the accord type R in Japan. i want my car to be fast and able to hadle too. thanx for the help.
-Phat-

Re:jdm h23a into a civic?
 

No but i do have an j spec h22 in my 92 hatch :P Do you know what the specs are on the jdm h23a? Cant remember. Anways....Its really up to you. If you already have the accord then just slap it in there. But if you want to take the civic route then that would be fine too. You shouldnt have any problem with motor being in there. And even if you are boosting it, the civic frame and aftermarket mounts should be up to par. Its not like the motor w/ turbo is gonna break the car into 2 peices. :P

And for the handling get some ground control w/ integra rates on kyb agx adjustable or skunk2/kby agx adjustables. I have the skunk2 integra coilovers with kybs and they hold up fine with the h22 in there. I've been with this for about 7-8 months now and the suspension is still holding up. I'm going to be boosting soon in 2 months. I'm still piecing together my turbo kit. I'm also going be at 8psi. If you need any help on the civic or accord h22 install hit me up i'll be willing to help you out.

h23 is non v-tec.

Re:jdm h23a into a civic?
 

You are correct but the h23a is the euro accord type r motor i think it makes 220hp

Re:jdm h23a into a civic?
 

I would put the h23 in the accord since it will slap it without much bitchin. Then just turbo the civic with the motor it has! It would be alot less of a hassle and if you are gonna put a h series in a civic you might as well get the vtec version.

Re:jdm h23a into a civic?
 

Racerxfear. i'm not sure what the spec for the H23a is. i was trying to look for the spec, but i can't find it. i found the spec for the H22a types S (220 hp) i will take pics fo that engine when i get it. i will send it to u if u want to see it. about turbo that H23a. i herad about the weak ring land. u think it can take 8 psi? i want my car to run in the 12 sec. possible?
That H23a is a vtec engine in Japan. i heard that engine is preatty hard to get. they don't really make that many of them. i can be wrong.

Re:jdm h23a into a civic?
 

I dont believe they use the h23a in japan its only used in europe i think

Re:jdm h23a into a civic?
 

Yeah i know they are pretty rare. I thought they came in the accord wagon in europe or japan with the h23 vtec. But then again i could be wrong. When you get the motor snaps some pics. I want to see that thing. Yes the ringlands are weak but with the right fuel management system you shouldnt have any problem. I used to have a 94 si 2.3 prelude with a swap h22 with a fmax kit. I was boosting 8-9 psi for a year and a half until it blew. Boost spike all the way to 14 psi. It was quick as hell then boom. The management system i use on that was the erl mf2 with 2 lucas injectors that came with the kit, apexi avc-r boost controller, and msd ignition. It was well tuned by Modern Garage in SLC utah. So with the right management system and tuning you'll be alright. The boost spike was my fault because the hose that connected to the apexi boost actuator from the wastegate came loose while i was racing a rx-7.

Its really up to if you want to throw it in the hatch or accord. But in hatch your goal for 12 second should be possible. My opinion is that its less expensive in a light weight hatch to get the power you need to hit the 12's. This time around i think i gonna use uderdata as my fuel management system with 450cc injectors on my h22 hatch. But as soon as this get finish i'll let you know how my project turns out :)

Re:jdm h23a into a civic?
 

the h23 is non-vtec ;D

Re:jdm h23a into a civic?
 

Racexfear: for sure i will send u pics when i'm done. i think i will go with afc hack for my fuel mangement. i will get the car dyno tune when the car is done. i can't afford for the H23a to blow up. engine cost alot. i just blew up an engine in my accord 2 weeks accord. for sure i won't be using fmu again. i was boosting 9 psi using fmu. i cracked 2 pistons on my accord.

Re:jdm h23a into a civic?
 

are you retarded?

Re:jdm h23a into a civic?
 

maybe but this should convince you that h23 dohc vtec exist :P

Re:jdm h23a into a civic?
 

blue valve cover.. DOHC VTEC.. Accord R... sounds like the JDM F20B..

http://www.hmotorsonline.com/shop/im...blongblock.jpg

Re:jdm h23a into a civic?
 

yeah i would also say that the blue valve cover is a f20b which i think makes just as much power as a type s prelude motor but with just less torque. i could be wrong.

Re:jdm h23a into a civic?
 

the H23a and the f20 both have blue valve cover. The h23a is a pretty new engine. H23a came out in 1999.

Re:jdm h23a into a civic?
 

correct

Re:jdm h23a into a civic?
 

All i could find hope it helps.

Re:jdm h23a into a civic?
 

thanx Buddy ro, but i don't think that is the spec for the H23a. that engine is out of a 99 accord type R. the guy is gonna send me some pics of the engine soon. i will post it up for u guys to see.

Re:jdm h23a into a civic?
 

i thought the euro accord type r came with an h22 with a red valve cover that made 220 hp. i believe the f20b is also a vtec motor. and the h23a is a dohc non-vtec prelude motor. im almost positive the accord type r came with a h22 i seen it in sports compact car. the magazine.

guys please read and stop skimping through the post. We're are talking about the JDM h23 dohc vtec. And the site is accurate because its owned by Honda :P

Re:jdm h23a into a civic?
 

It cant be that hard to understand here is the quote the h23 dohc vtec motor exists

"The sporty Accord and Torneo SiR/SiR-T S-packages, the attractively priced newly upgraded Accord and Torneo 2.0VTS 4WD F-type and the sporty Accord Wagon SiR grade, powered by a newly designed 2.3-liter DOHC VTEC engine, are being launched simultaneously from January 21, 1999."

Re:jdm h23a into a civic?
 

The only problem with the h23 dohc vtec is that it only came in auto. :-( I guess that isnt really a problem... but i bet that would have been a killer 5 speed tranny considering the auto h23 dohc vtec tranny is LSD

Re:jdm h23a into a civic?
 

AUTO? i think it comes in stick too. the guy told me that my is a stick. i'm gonna build up the engine before i put it into my 95 accord. i'm gonna sleeve and put pistons and rods in the bloack. i want that engine to take 15 psi. i heard that engine is making 220 hp stock. if i boost 15 psi, then i sould get double the power. 440? that sould like alot too me, but we will see how it goes. i think i should be able to run 15 psi with afc hack. i'm gonna run 550cc injectors instead of 450 cc. if the 450 is good for 12 psi then the 550 should be good for 15 psi. i did the equation and it seem like is gonna work.

Re:jdm h23a into a civic?
 

In my opinion, the jdm h23 is to much of an engine to be put in a civic.I think you should put it in the accord and go with the sleeper look...

Re:jdm h23a into a civic?
 

i'm not sure what the spec for the H23a is. i was trying to look for the spec, but i can't find it.

H23A1 has 9.8.1 comp. ratio 160hp@5800 156lb-ft@4500
H22A has 10.0.1 200hp@7000 156lb-ft@5250
H22A1 has 10.0.1 195hp@7000 156lb-ft@5250

the H22A1 in the 99+ prelude has 200hp in the USA (along with the 97+ SIR prelude from japan) but the H22A (97+ prelude type S) from japan has 220hp

Re:jdm h23a into a civic?
 

i got an h23a (non-vtec) jdm engine in my coupe. it is identical as the h23a1. i will post some pics as soon as i can figure it out. if any one wants i can e-mail. but if u know how to post them into a thread please let me know..

Re:jdm h23a into a civic?
 

why dont u just slap a h22 head on that h23 u got there vtecwithboost. heard its pretty easy like doing a mini-me. but pushing as much as a type-s motor.

Re:jdm h23a into a civic?
 

i thought about it but then u got to put the oil squiters and stuff in the block i heard. i am actually looking into an f22 block with the h23 head. but if that doesn't happen i am still gonna boost it! i have seen some preludes turbo's with 245 to 250 with only 6 psi. i am hoping that 10 psi will easily put it over 300!! if not i always will have 10 lbs of nos in the trunk!

Re:jdm h23a into a civic?
 

that's an oxy-moron... "turbo an h22 and put it in a civic"... I personally don't see why anyone would put an h22 into a civic, but if you did, that would be better suited for an all motor car... you can get the same numbers turboing any motor... Why don't you spend $2-3000 less and build your stock motor or swap a b-series and turbo it. Stock LS's put out about 250hp off of 6-8 psi... why spend $2500+, fuckn up your car's weight ratio/suspension, just so you can say "I have an H22/23 turbo" and get the same performance... going in a straight line, that is

Re:jdm h23a into a civic?
 

NO WAY.. ITS NOT AS BAD AS U THINK. GRANTED THAT THE CAR WILL LET U KNOW WHEN U AR GOING ALITTLE TO FAST INTO A TURN. BUT GET THE EXTRA 20 TO 30 LBS OF TORQUE OUT OF U UR LS... OR THE 40 MORE IF U GOT THE B16....
plus all the ls and b20 hatches around ain't ---- compared to the h23 i crush them all. i got three friends with ls's and they will tell u everytime i get them by about two car lenghts
plus i only got $1100 into my swap so i figured it was more worth it then putting an ls or b16

Re:jdm h23a into a civic?
 

alright... here's a dyno of an average N/A h22 w/ full bolt-ons and no cat ($3500-$4500 Swap + price of bolt-ons and suspension mods) - 176 Hp

Heres a dyno of a N/A GSR w/Type-R pistons ($2000 Swap + bolt-ons) - 173 Hp

Now... Here's a Turbo H22 (7 PSI - 231 Hp)
