Icon5 H23 vtec

I need help on doing this swap for my 5th gen. I need to know what problems that I will run into to get this thing running. I heard some good things about this enigne and the trouble to get it started but I just want to know if its worth the swap or should I just get an H22a?

Re: H23 vtec

dude swap in the H23v. just be advised the H23 doesn't rev as high and they don't cost as much as H22a's well at least not from what i have seen. But what you can also do is take a H22/23 block put an H23/f22 crank and rod in it, run some type S pistons, mild cams and you will have a nice some what cheaper build considering if you can find the spare parts and have the place to build it.

Re: H23 vtec

its the same as any jdm h22 swap as far as dropping it in . if you want to use all the factory harness without modding it you need to swap the oil pump housing and the intake manifold . as far as the myth about how high these motors rev check out this article

http://en.wikipedia.org/wiki/Honda_Accord(clip specifically about this motor Accord Wagon SiR (CH9 FWD 1999-2001, CL2 AWD 2000-2001)
The SiR wagon model included the only 2.3 LITER H23A DOHC VTEC H-series engine in the Honda line-up. The H23A engine was rated at 200 hp / 190 hp (AWD) at 6,800 rpm and torque of 162.8 lbft (220.7 Nm) at 5300 rpm, 10.6:1 compression, 87 mm (3.4 in) X 95 mm (3.7 in) (Bore and Stroke), and a 7300 rpm redline like other H-series VTEC engines from factory. The H23A also came with a blue valve cover and was the largest displacement for the H-series Honda engines. The H23A was mounted with a tilt towards the driver. The H23A had a longer stroke than the H22A. Specifications for the H23A were; 87 mm (3.4 in) X 95 mm (3.7 in) (Bore and Stroke)and H22A has 87 mm (3.4 in) X 90.7 mm (3.6 in) (Bore and Stroke). The H23A had better acceleration because the peak torque occurred sooner at lower rpms when compared to the H22A.)

the 2.3 vtec dose not redline at 6300 as most will lead you to believe . i have had mine in for 10k now and i spin it over to 7500 on a regular basis with no issue whatsoever . the motor makes much better mid range tq as far a a dd this is the best motor in my opinion . not to mention it cost a good bit less . if you have any questions shoot me a pm ill help you in any way i can . btw a friend of mine just bought an 06 e46 m3 and my car and his were dead even he beat me by a car once and i beat him by a car once ( over 100 he put it on me but not to shabby for a 5th gen lude ) . there great motors out of the box . if you can wait a few months ill sell you mine as soon as my lazy ass gets the built motor together .

Re: H23 vtec

yeah I want this swap because I don't think anyone has every done it in my area. I know i can change the manifold from my H22a4 SH to the H23 vtec and i have a base model 5 speed tranny for the engine also. What would I have to do to get it running?

Re: H23 vtec

its strait forward swap same as any jdm h22 swap . need to swap the oil pump housing and the intake manifold . bolt the flywheel clutch and trans to it and drop it in . i did not modd my factory harness at all . alway a good idea if you are going to do this yourself to get 2 engine stands and set them side by side . compare all the sensors on the motor as well and swap as needed . to do it all right including timing belt water pump seals and all i was done in a day . but i have done quite a few jdm swaps before . like i said if you decide to go this route and have any problems hit me up ill help you out .

Re: H23 vtec

hey i just finsihed this swap in my car. tooo easy to do. just a few things you gotta do, so you dont have to cut up your stock harness. like swap the dizzy and oil pump out for your usdm ones.

after that any parts for it should be bought as is it were a h22a. only real things that are different as far as parts, are the crank/rods/pistons. and the fact that the h23a doesnt have oil squirters in the bottom end like the h22 does.

oh ya, and gonna want to swap over the main crank pully, as the h23a vtec, didnt have power steering. even if you dont think your gonna want it, still a good idea to swap the pully just in case you change ur mind down the road. save ur self the hassle.

Pm em if you have any questions, i did alot of research on the motor before i swaped it.
