I blew up my H23..now getting an JDM H22a1..for my 95 SE...are there any changes that need to be made? I have a guy taking out my H23 and i first told him i was buying another H23..he said "have the H23 shipped to my shop and ill take out the blown one and drop right in the new one for $300"...now since i have told him i was getting a H22..he wont give me a quote since it is a different motor and he dont know what all he has to change...anyoine know what is different when swapping froma H23 to H22? what all have to be changed? i heard about 2-3 wires for VTEc, and thats all...I NEED HELP!!!

Hey man there is changes. you have to wire the vtec. use your h23 tranny.it will bolt onto your h22a1. how much did you get the h22a1 for. i can get motors like (jdm) h22a's,b16's..etc. i think thats the biggest change you would have to do. is just wire up the vtec. i have my h22a with a h23 tranny and it gives better gear ratios. let me know how it goes or if you want or know anyone who wants motor. all my motors have 100% start up warrenty.

 

Layoff the crack bubba, the h23a1 tranny dont give the H22a a better gear ratio. If anything the H23a would drop below vtec on every shift.

 

stick with the h22 tranny

 

i am currently doing this swap with my 94 4WS Si. if you get an engine swap with the tranny attached, it is not much more than just the engine. i got my complete setup h22a, tranny with shift linkage for a total of 2600 dollars.

now, the actual install of the engine is very simple since all of the motor mounts match up. as long as you have an engine lift, you just take the engine out and drop the new one in. a few mounts later and you are done.

what got my wallet was all the little things i needed. for instance, someone already mentioned the vtec issue. you have to run 3 new wires to the ecu for vtec. go to http://www.helminc.com and they hav the electrical manuals you need, its rather simple. also, the h22a redlines at 7200 rpm (this is different with some other h22a, but mine was at 7200). this meant i had to buy a new gauge cluster, which cost me 115 dollars after looking around. i also had to buy 2 new pedal assemblies because i went from an auto to a manual. lastly, i had to buy the shifter lever and ****.

also, the battery i had wouldnt start the engine, but i think that was just because it was a really old battery. i had to buy a new one. that is really all the information you need. my good friend is a mechanic and he did all the swap work with the engine and tranny, and i installed the new cluster and assemblies. that is the easiest part. good luck!

 

h22 tranny is better.
