H22a & 4th gen civic...

Yes I know, its like mixing vinegar and water...

But if you caught my other post, the car is currently automatic ~ and H22a is about the only thing I can think of that comes in auto form... so would it work? I know its alot of pounding and cutting and taking out things (hehehe who needs a steering rack? ;) ) But how hard is it really... I hear going from auto to stick is costly, but this doll is just too much to pass up, so dont tell me to look for a manual :D

ive read in a bunch of places that not only is an H-series motor in a civic is a pain in the ass but also that it throws off the weight distribution of the car and that afterwards it cant handle for $hit, this site can probably explain in a little more detail : http://hybrid.honda-perf.org/tech/badidea.html

I've heard a lot of bad stuff about that too, but a guy that works at one of the shops in the city had a H22a in his Civic, and he said the handling was fine. It was pretty damn fast too, I heard he could run 10's. And it was his everyday driver. He drove his kids to kindergarden in that car.

Well actualy you could do a B16a swap useing an Auto equiped B16a from either a 2g Integra, or a 5 or 6g Civic SiR, all of which came with auto's in Japan.

The engine is a little detuned, and it will never be as fast as Manual version, but it would be a hell of a lot easier than trying to cram an H22 in there, and then get that power onto the road.


But then, 4g's are so cheap and common why not just sell yours and buy a manual Si?

I thought you had a 5th gen...

Anyway, it is not that costly to do the switch over. If you are replacing the engine anyhow, you are probably going to replace the trans, too.

Mine was an automatic. I got the engine, trans, shift linkage, pedals, clutch fill/master cylinder, & instrument cluster with my purchase. The only cutting and welding that I had to do was...the trans mount had to be lowered (from the frame to meet the trans.), the hole where the auto shifter had to be elongated and I had to cover the large gap left from the auto shifter with sheet metal. I ran the clutch lines (not very difficult). I also left gear selector switch from the auto to trick the ecu into thinking the car was in park or neutral (I just hid it under the console)...so I didn't have to buy a switch for the clutch. The only disadvantage to that is...I can start the car without the clutch in. (The advantage is I can switch it...and the car won't be able to start...great for vacation).

It all took me 4 nights (after work)...the only help I had was bleeding the clutch.

I had to run a wire for vtec, from the fender connector to the ecu and tap into the proper pin on the ecu.

i kinda have to agree with moppie, go and trade it in for a manual or whatever. but then again ive never attempted an auto to manual swap so i really dont know whats invloved, anyway good luck with all that

H22 in a ef.... http://www.geocities.com/kustomautoworks/tech.html

In doing this swap, you need to reinforce the frame really well. That's the only thing I've heard. The standard Civic engine torques one way when running, but the h22a torques the opposite way, so the Civic "frame" isn't built to handle the opposite torque. Hope this helps
