I have a 92 Prelude si with a blown H23 with A/T. I like to keep the car as my daily driver. So, I was thinking of getting an H22 with A/T http://cgi.ebay.com/ebaymotors/92-96...ht_10435wt_935.
I do know, I have to run two wires for vtec solenoid and pressure switch. Is there anything else I need to know?
Thanks.

 

Anyone? Damn, 112 views and no one has done this?

 

Idk man, h22 in auto car? Something isnt right. Yes it is possible and everything will bolt right up. I think you may need to get different ecu unless the swap comes with one. But I dont understand why you would want an automatic h22??

 

My h22 blew thru (2) transmissions. after only lasting 10k miles on the low mileage jdm tranny i swapped to 5-speed and have been in love ever since

 

I say that getting an H22 in their is a great idea in any way. That is a great engine and there are some strong mods that add to the IHE mods most people do. In order for your car to hit vtec, yes it needs to be wired and there are multiple sites with step by step instructions and, it also needs to have a way for the vtec to know it is time to go. Finding a ecu for an automatic with vtec should not be too hard. Seems like thereare plenty of auto vtec accords. THey have F22 and F23 in them.

The wiring is no big deal. You can either make a sub harness for it or you can buy one. Hopefully you will get an h22 with a harness on it. That way you can just extend the wiring and into cabin and then incorporate into your existing ecu harness.

If you are in an OBD1 car, that makes things easier when you need to mod computers for programs with chips and to mod the ecu with adding components.

Of course, you can also run vtec off a vtec controller or just run a switch. You can buy a cheap engine starter thing with button on top for your thumb. Extend the wires to reach the vtec solenoid with one lead and then to the pos battery on the other. You can also do this into the fuse box. When you want to open the valve, push button and hold until you want to let loose.

An H22 should work fine and not be too difficult to get in there.

Start saving and collecting gathering the parts you need for the manual trans swap. Start shopping for an H23 trans too like an M2S4. Axles are cheap. You will need to change the Pass side trans mount for 5 spd.

Hope this helped.

 

The thing is, I'd like to keep it automatic for now. The reason for this is I'd like to it simple, since I'm the only one who would be doing this and also, since I'm somewhat new to it.

 

It's like being able to marry Adriana Lima but with one tit. Get the manual! Full potential =D. You'll regret that you didn't when you aren't new to it any longer.

 

Agreed, You will drive it for a week and think its awesome, then after you; be like " wtf? If this was stick it would be so much more fun and so much faster"

 

Just do it if thats all you can afford. Its better than the stock H23A or the F22A Auto.

 

^ Dito that.

I can give the Jdm H22A auto a thumbs up. It is indestructible when not boosted, gear ratios are really wide (a positive and a negative.lol) and doesn't pack up like the 5th gen one. I can do 0-60mph in 7 seconds with a dead start (no launch/revs), plus top speed in second gear is around 125km/h (78miles/h), making passing maneuvers on the freeway great!

But if you can afford a manual its worth it, its gear ratios are made for acceleration.

 

Yup. Either way, its better compared to the stock engine.

 

Do you currently have an H22 A/T in your Prelude? If so, how hard was it to do?
