Hey guys. I'm looking to h swap my integra. I was just wondering what motor i should go with. Ive seen jdm h22a, h22a euro r and jdm h23a and have no idea what the difference is. Can someone help with some details on them all and recommendations on which one i should choose? Just like some pros and cons and which you guys think are better. I wanna do some research on them before i pick.

Have owned both, they honestly felt the same. H22 had identical bolt on's done to it, same car. You won't notice on the butt dyno. If you know how to use a wrench then the h23a is the clear choice. Why you ask? Because they are so damn cheap. $1000 on average compared to $2500. All you need to do is convert to obd1 which is super easy. There are a few parts required easily found at a junkyard or you can purchase new.

h23a is basically a stroked h22a. it has more low and midrange torque. peak numbers are about the same though. h23a redline is also a couple hundred rpms lower than h22a.

Alright so you guys are saying the jdm h23a is better then any h22 correct? And dumb question, but does h22 bolt ons fit on the jdm h23? What kind of builds can i do with both?

Really both have their own good qualities. For a swap into a civic, the H22 might be the way to go, as you can rev it higher out of the box, and don't need the low end torque as much as a Prelude or Accord.

The same Mods will work with either engine, as the heads and all external stuff are identical. The H23 does seem to have poorly designed pistons, so big cams are maybe something to stay away from on that one.

Right now im pretty set on the euro r h22a but im still considering the jdm h23. It just all depends how much power i can get out of simple bolt ons and what i can do with it in the long run

Alright so if i were to semi build one like the head then the h22a euro would be the way to go? Or just any h22a?

snobordboy

Semi build as in valvetrain and cams on a stock bottom end? Just a standard JDM H22A, no need to spend the cash on the euro-r if you aren't using the cams.

Well i found a euro r engine cheap (on ebay sadly) but the specs seemed promising. I go to auto tech school so even if it did need a rebuild it wouldnt matter much. if its in good running order id just drop it in. And yeah semi build as in build the head. And i was thinking later on id tear into it some more and actually build more. Im just trying to find the best one really. I've been thinking about the swap for a bit and got it down to those 3 and have been stuck really haha.

So pretty much drop it in drive it for a bit till it actually breaks then build it. Thats my plan

Euro R engine is the 220hp H22 so you will have the Type S cams in the head already stock.
So just get that engine.

I bought a euro R engine on ebay from a place in New Jersey. $1299 without ecu. Havent installed it yet but its here and engine looks great. Don't buy a euro R if your already planning to put bigger cams and better valvetrain. It defeats the purpose of spending more for this motor to begin with. Just have the h22 ported and upgrade cams in that or buy the euro R and let it alone.

Ive seen H23s way cheaper then $1000, I think as low as $600.
