After buying a few motors for some customers and our shop cars, the shop I work at has a decent hookup (I guess you could say) on getting engines. I'm looking to buy a friend's 93 Prelude Si after I get rid of my car, and I'm looking at engines to put in it. The car had a jdm h22 previously, but it dropped a valve a few months ago and he doesn't want it anymore. I tried searching and couldn't come up with too much information.

According to the company we deal with, we can get the JDM H23A or the JDM H22a for the same price. I didn't know if there would be an advantage to me getting the 2.3 over the 2.2 considering I could get both for the same price (long block only).

The car will probably only see bolt on mods so I'd like to begin with as much power from the get go as I can.

All opinions are welcome. Thanks in advance

 

Get the JDM H22. It has vtec. It can rev higher. With good bolt ons, you can make 200whp.

 

They're both rated at 200hp in stock trim, but the JDM H23A would probably be more fun to drive around daily - it has the same 95mm stroke of the USDM H23 so it will have more power earlier in the rev range compared to the H22.

For what it's worth I'd love to have a JDM H23 crank to drop in my '01 H22. That would basically turn it into the JDM H23...

How do you know which H23 he is talking about...? He could be talking about the 160 HP one or the 200 hp one...

 

if its the h23a (like he wrote) then its the 2.3l vtec engine. if its the h23a1 then its the 160hp engine.

h22a vs h23a then i vote h23a all the way!

 

Honestly, If it were me, and I had the money, theres no doubt in my mind that I'd go...


JDM F22B BOOSTED


It's basically a DOHC H23 Cylinder Head with an F22 Iron Sleeved block, perfect for boost and good torque, and reliable.

 

the H23A is great. i love mine. if you want usable daily driven with the same hp as an H22, this is a very good choice. and almost all parts are interchangable.

Because the JDMland counterpart to the US's H23 was the F22B. If he's talking about the JDM H23A, it has 200hp.

 

well if you can truely get a h23a for the same price as a h22a, then obviously get the h23a. dohc vtec with 95mm stroke and 55mm mains so no worries about spining a bearing. its a no brainer. crist iwould love to get a h23a for the price of a h22a but on most websites that sell motors, they are way over priced

First off they are both DOHC vtec motors, but I have seen more modded H22a motors than H23a motors. doesnt the H22a have way more potential?

no. and yes, they are both dohc vtec motors, but neither has more potential. the h23a has more stroke for conceivably more torque and a nicer curve. and just because there are more h22s out there doesn't mean anything.

agreed, i think that the performance potential is equal, after market parts will be equal for both motor because they use nearly identical heads, so aftermarket cams, header, intake mani, etc will all work.

and just to clarify, are we trying to say that the h23a and h22a are BOTH dohc vtec?

 

For the same price get a H23A, its rare not alot of people have it. you can still drop in aftermarket high performance part from a H22 but with a H23 you have more TQ and over all Not alot of people have it so you'll be one of a kind.

two of a kind.
and i know a couple of more people have them too. although not many have been as breathed upon as mine.

yes. both are dohc vtec motors. same block and head. just different cranks and rods.

 

...how much? I want one now

 

iown the accordwagon this engine came out of and it a sweet car to drive.

Could you clarify? 95mm crank perhaps? I assume the bore in the H23a is also 87mm like the H22a?

I thought the H23A was the Euro Accord R wagon **** and was rated at 220hp not 200.

 

I have seen many and many H23A for sale on ebay but I have never seen one that wasn't mated to an auto tranny.

really? i thought the h23a's in europe with the wagon's were in auto but i could be wrong.

 

im actually pretty surehe isnt talking about the h23 vtec they do make a jdm h23 NON vtec. my friend works for japanstarmotors and he has a couple complete swaps soo he is most likely talkin about the NON vtec version.

 

all of the true dohc vtec h23a engines are mated to an auto trans. that's the only way honda made them. if you see otherwise, run away quickly.

the nonvtec ones you'll see all day, but you'll know it's different by the valve cover.

and you!!!! i envy you. this is an awesome car/wagon to own.

 

some pics of the ch9 accordwagon. iwill post some more pics later

 

yes^^ the h23a vtec came in that car, and its ONLY automatic

televator, 95mm stroke means 95mm crank, theyre both 87mm bore

the h23a will make more power in any situation over the h22a, the h22 will like to rev higher though...

I think you're refering to the H22A Euro R. Similar to the jdm h22a Type S motor. diff intake mani. etc... thats the 217-220hp motor anyway
