96 accord lx 4 door. lookin to do an h series swap soon. should i go with the less expensive more powerful h23 or the h22? any input would be great

 

Not sure where your getting your info from but the H23 does not have more power than an H22.

H23A1 - 160 crank hp
H22A1 - 190 crank hp
H22A4 - 200 crank hp
JDM H22A Type S & H22A7 Euro R - 220 crank hp

What are you goals and what is your budget?

You could rebuild & boost your F22B2 and can get more power than the H22 or H23.

 

If you plan to boost go hybrid and do a g22/g23 f series bottom ends are stronger than h series and can handle more boost. F series come with lower compression as well. A g series is when you put a h series head on a f series bottom end.

 

hes probably referring to the h23a out of the accord sir wagon, its the the same rating as the jdm h22a from the prelude type-s.

 

heres where im getting my info from:

h23a http://www.jdmenginedepot.com/jdm_en...Prelude/Accord

h22a http://www.jdmenginedepot.com/jdm_en...Prelude/Accord

 

Actually the G series is a 5 cylinder Honda engine. FYI, If you want a reliable engine it won't come from putting two different series engines together. It works but it's not worth the haste when you can buy a complete engine that will end up with the same power per/$$$.

OK that makes more sense then. Most people don't think of the H23A VTEC. You still didn't answer the main questions though. What are your goals & budget!

Goals = Power & RPM Range. End use for the car, daily driver, street & strip, street & time attack....etc..etc...N/A or Forced Induction. How much are you willing to spend to get the end result. The H23 seems like it would be a better deal for a drop in swap. But if your looking to go forced induction and get your Hp up into the 300 range. I say drop the $1k+ that you would spend on the H23 and boost the F22.

 

its really upto to you. the h23 is more unique, and pretty much the same parts.

 

Just to add to that..... unfortunately the H23 doesn't make 220hp.... and it definitely was never a Type S.
Here's a Type S engine.... and they state it has a compression ration of 10.6:1 (fairly sure the Type S was 11.0:1??)
http://www.jdmenginedepot.com/jdm_en...Type_S/SH_H22A
So I'd take allot of their info with a grain of salt.

But yeah both those engines you put up are good for 200hp.... but I guess the H23 would make more torque just with a lower peak RPM. I'd go with pretty much any advice GhostAccord gives you though.

 

I didn't even see that they had it listed at 220. The VTEC h23 is definitely not 220. I'd give it maybe 190-200 tops and a lower red line. lol They even have the H22 listed with a lower red line.....

 

I thought the Type S was more like 187@the crank after u figure in the power loss in the drivetrain?

 

at the crank, is before it goes through the drivetrain. its about 187 at the wheels.

 

My Euro R with a Panel Filter Insert, Headers & Test Pipe (both borrowed) made 141kw at the wheels - 189hp. The engine is rated new from factory as 220ps @ flywheel

 

Actually the A7 is advertised at 212hp

 

i got my H23 from the same spot. I haggled a little bit with Will the sales guy and got the engine and the PCB ecu for like $900. Would definitely recommend both the H23 swap and JDM Engine Depot.

good luck

 

The A7 is a EDM Accord Type R engine, which you are correct in saying 212hp..... The Euro R H22A7 (not actually an A7 but everything in the build is identical) is a JDM engine rated at 217hp (220ps) from memory the hp is altered via the lower octane rating of the fuel.

All in all whats a few hp between friends??

 

My Euro r is stamped H22A. Not H22A7. Its a true Euro r. I understood the camshaft profile was different between the H22A7 and the Euro r. Is that true?

 

Yea that's what I meant, 187@the wheels...


hell for a Stock Dual Cam motor if that's dropped in something light that ****'ll move.

 

no the cam is the same, they used a different header.

The Header is different because the JDM Euro R has EPS (Electronic Power Steering) like the EP3 & S2000

 

so since everyone else is changing the topic, i want to thank ghostaccord for answering MY question. i hate when other people hijack MY threads with other off topic questions. MAKE YOUR OWN THREAD! that dude ghostaccord is the ****! every time i post a question he always has an informative answer. my project car that i want for speed, unprofessional racing, and just dickin around with is my del sol so i just want to note that this is going to be my daily driver all year around and even in the snow. im going to keep the engine 99% stock. i may put an intake and header on it if that, but keep everything else original, even the exhaust because after drinking a few brews i dont want to draw any extra attention to myself. this car is no gem by any means i just hate driving an automatic so i have been planning on doing a 5-speed conversion ever since i bought it 2 years ago. Because the car is nothing special i dont want to drop in a $4000 type s engine, and keep my spending to a minimum. the h23 engine tranny and ecu from jdm engine depot at $900 is not much more money than it would have cost me to buy a 5-speed tranny and new flywheel so i figured why not replace the gutless f22b. the f22b is a good solid reliable engine but they are just worthless for power unless heavily modified, just like any honda 4cyl sohc engine. i would recommend jdm engine depot to everyone. good engines at good prices. much more reasonable than hmotors online. just for the record, im not a dumbass. i didnt mistake the h23a for the h22a type s, so i dont know where someone got that idea. i also know that an engines rated hp is never what it makes at the wheels, any advertised horsepower is always bhp unless otherwise stated whp. even off the showroom floor engines never make the power they are rated for. engines are mass produced and not blueprinted from the factory making everything exactly to spec and until they are, they will never make their advertised hp. i remember reading an article that was about a test where they took 10 identical engines out of brand new mass produced cars and put them on a dyno to test hp. if my memory serves me correctly they varied by 15+ hp. so anyone who says there car is 150 or w/e hp cuz thats what its rated for is full of ****.

ghostaccord - i got a couple questions for you, since im going to be dropping a dohc vtec h23a in a non-vtec 96 accord lx, what kind of advice can you give me. my most important question is: can i use the f22b wiring harness with the new engine and just run the wires right off the ecu for the vtec solenoid, and knock sensor. since its a jdm engine theres no oil pressure sensor so i wont need to run wires for that. also do you know a couple good threads for both an h22 swap, and a 5 speed conversion for my year accord? thanks in advance man cuz im sure the guru will know what to do.

good catch on someone elses mistake or just straight stupidity! either way hilarious lol hahahaha

 

the f22b wiring harness will work. you should have no issues running wires for vtec and knock straight from the ecu. i believe that the jdm does have an oil pressure sensor. but so does your car so no biggie there.

as long as you order an obdII motor ( i have no idea what years the h23 came in) you wont have a problem. if you are buy an obdI motor you will need a conversion harness at the least. im not sure if the immobalizer and crank position will be a problem or not i know they are on the h22's.

for a 5speed conversion you will need the pedals, master and slave cylinders, hard lines and some time.

 

AFAIK the H23A VTEC is OBD2 (97-01)

What ECU are you planning to run? The H23A doesn't come with one from JDM Engine Depot. That will determine what if any ECU wiring harness that you may require. Remember that there is no USDM equivalent ECU to the stock H23 VTEC, The H22 P13 would be close, I guess. However there is only a very smal window of OBD2 P13s that you can use for this swap. That small window is the 96 OBD2 P13. It's the only OBD2 H22 ECU that comes without the immobilizer circuit.

As for swap DIY's. The ones in the FAQ are really the only ones that I am aware of. I am sure there are more on other websites though.

5spd Swap

H22 into 5th gen Swap

 

Read the information about this engine you posted the URL for

If you read the advertisement on the H23A in the URL you posted you will understand why I said what I did
("said" it was a H23A Type S but they have since changed it), I wasn't saying you were a dumbass at all..... just stating that you should take their information with a grain of salt as they have lots of incorrect information on their motors - Goes on to say that the H23A has a redline of 8k rpm
(I used the Type S as an example).

As for the ECU problem see what crx 91si wrote:

See if you can get them to supply an ECU with it, and PM crx 91si as he is a whizz with the wiring of them!

 

To get it up and ruunning you can use the ECU from the obd2B JDM F20B which is the PCB, with a fuel controller or some sort which is how mine is running. If you can find a manual PCF ecu, that will work also, but definitely not easy to come by from my expirence. OBD2 JDM ECU's do not have immobilizers either. And AFIK, the JDM Engine Depot only has the auto versions of the PCF which will not work. I've tried. The down side of going the JDM ECU route is you loose the functionality of your diagnostic port for emissions inspection.

You could always have a USDM Prelude ECU programed to your key at the dealer. It's not that big of a deal to do it, but getting the car there might be more then the key programing if you live far from the dealer or don't know anyone with a tow truck.

 

and if you go with a JDM OBD2 ECU, swap pin A14 to A15 for the FPR

if you need wiring diagrams, PM me and let me know
