i have a 6th gen accord. i know the trannies are compatible between the two.. so my question is, can i swap just the engine and ecu into my accord? do i need a new wiring harness as well or could i reuse my current one?

 

you shoudl alwyas reuse your current harness unless it is too damaaged to be used.

 

well, my question was more in the nature of if they were compatible.

 

you can re-use it with some modification


dont waste all that money on an h22 if ur not gonna get a h22a tranny too

 

why would it be a waste? f23 transmissions are cheaper and geared longer (plus points in my opinion) and they share the same clutch/pressure plate/flywheel as the h22 transmissions (more plus points)....

 

i suggest u do a complete swap, transmission and everything else.

 

It can be done, but it doesnt make much sense. The Tranny and the engine run on computers and its not worth any possible confusion. Since the H tranny is geared specifically for that engine, it would be much more reliable. Especially if you have a 6th gen auto I hate my tranny.

if you think longer gearing is an advantage in this situation you should really reconsider what the hell ur doing dropping money on a different engine and just start reading

 

W3rd! I agree. Only benefit from a longer geared transmission is fuel economy and top speed. Who cares about top speed when a factory ECU governs itself at 115 and that's way too fast in my opinion. BUt you also probably wouldn't be worrying about fuel economy if you are doing a motor swap.

 

yes, i know about the gearing of both trannies.. i'm asking because my engine has problems and my budget doesn't allow for a full swap right now. in a few months the tranny will also get swapped.. but longer gearing with an h22 is still better than a car that doesn't run period.

 

Heres some advice then.

1) save and buy both.

2) Buy the motor only, and take it to a reputable shop where they can test it and (perhaps) rebuild it if not just tear it apart. Then your car will be guaranteed to work

i already planned on doing a compression test before i buy it.. after i purchase it, i'm doing a leak down test, and lastly, taking it apart to clean everything thoroughly.. replace parts as necessary..

getting back on topic.. Evil Nick M, you said "you can re-use it with some modification"

do you know what modifications are needed to the wiring harness? links? thanks..

also thanks to all for your inputs..

do a few search's the info is out there, basically you ll take your harness and the h22 harness cut and split the little sensor that fit.. some stuff needs to be lengthen

some sensor wont fit the h22 so you take the ones off hte h22 harness adn put them on yours.

 

If you buy an h22 without the tranny be aware that some of the auto versions had only 180 versus the 200. So even though you think you might be getting a great deal you might have been better off getting another f23.

Also I didnt know that the manual transmissions were controlled by the ecu, is that just a 6th gen thing?

 

AT's are

 

Thats just my point what does an AT have to do with this thread?

He might presently have AT (most 6th gens are) and wanting to switch to manual. Or the tranny he's getting may be (but doubtful) an AT

No, YOU'RE owned you moron. I can think of about 3 places in the US where hitting speeds of 118 are legal and nowhere are they safe in any case. Do you have a rollcage? Were you wearing a helmet and strapped in with racing harnesses?I'm assuming it was on the highway. What if you lost control, or if you hit some family just driving home? Did you risk the lives of any passengers? That's an asshat thing to do. Accords were never meant for high speeds and just flooring it may seem fun but it's one of the most dangerous things you can do. I hope you dont do this in the future.

Reading Pwnz j00 d00d!

 

You cant back yourself up with your own quote! That doesnt make any damn sense. You were the only one talking about an auto.

No he might not presently have one, everyone makes mistakes dude its ok, you dont have to get pissed. If I were to be wrong then thats cool, like I said I wasnt being a dick, if I were being a dick I would have jumped on what you said right away. I was trying to give you a hint with the first post I made.
I still say owned! j/k

 

get the h22 tranny... highway mileage is going to go down, but you'll accelerate faster. might also top out sooner... but oh well you'll get there faster. anyone care to post the gearing on the 2 trannys in question?

you're assuming that i'll have an h22 harness..

Don't do anything half fast. Save up and get the tranny and engine at one time, especially if you are planning on getting the tranny. You'll have to use the F23 harness and modify it to make it work with the H22. You don't need the H22 harness.
