i am about to do a engine swap on my auto 90 accord ex. what i need to know is what is the difference bettwen the 90 accord ex engine and the 90-93 accord dx lx engine. can u put dx lx engine in a 90 accord ex. will the motor mount go in the right place will it bolt up???? what about the auto trans! will lx dx ones go to the ex accord? if i buy a lx or dx engine for my ex accord should i buy the engine with the trans or just the engine???please help me out no one at automotive forum know ****!

 

**** man now one knows the answer to my questions

 

i believe the only differences between the LX DX, and the EX is that the lx/dx have different exaust manifolds, engine computers (pretty sure..and lx computer works with ex) and a few other things that accounts for the extra HP... but the physical motor i believe is the same. since its an F22. so it should just go right in.

 

thanks man. i have been waiting for the answer for 2 weeks and i posted the same question to other honda forums and now response. thanks a lot desolate

 

As far as install, they are all the same as far as power they are NOT. The EX has 130 HP and the dx/lx only has 100hp. and as he said, the EX has different exhaust.

They have real headers 4-2-1 where the lx has manifolds.

The EX trany also has little more "umph" the the others. It comes with a "sports" mode that the others do not have.

 

**** man i got more reply today then in the past 2 weeks. i just wanna know if it all going to work and if the ex header will conect right to the lx or dx engine. and dx lx have only 5 HP less then the ex and the dx has the "sport" thing because i already owned a dx.(loved it)
thanks for the repy guys

 

Alright the main difference between the ex and lx dx is the ECU, exhaust manifold, and intake manifold. All those account for different hp and tq between models. The ex IM and EM can go on either engine (since they are all f22a). And as far as the tranny with "sport" mode. All it does is increase the shift limit (same redline) but if you were to press the gas down 1/2 way normal mode would shift at about 3-4K versus "sport" mode with the same gas depressed will shift at like 4K to 6K. Personally its a waste of gas and if you want to redline it all the time just go WOT. Also it will be more eager to downshift. I have it on mine and NEVER use it.

 

They are all interchangeable. You can swap any F22A into that car. Use EX Intake and Exhaust manifolds.

 

Hey thats 125hp for the dx and lx not 100 thats like the third generation accord with 98 hp That would suck!!

 

unless your motor is just plain bad, you could always just do a vtec headswap for much cheaper...here's an article on the how-to:

by the way, join that site if you aren't a member already...great technical info and detail strictly dedicated to accords...

 

thank you guys for the reply. you have been more than helpfull to me. thank u again.
hey nick H do u know any website where it shows how to change the engine of a 90 accord???? i read the manual but still need some help. and thanks for the link about the headswap and how many HP does the vtech head add to the accord. thanks again guys

 

an f22a6 head would be as good/better and straightforward.....from the 92-93 accord ex/se........not vtec (the SOHC f series vtec heads are for better gas, not more power)....compared with the other 90-93 accord motors, the f22a6 head has a better cam, flows better, the intake manifold is a better design, then you just use the ex ecu to control it all and you have 140hp or so........should be cheap, really simple and just as good......but the engines are all about the same except for the 92-93 accords being external coil and the 90-91's are internal......trannies are all interchangeable also......if you want more power, you can always swap in an h23a1 or h22a or something if you have the money...really easy to do that also, if you have some tools and somewhere to do it

 

thanks again for the replys. for now i am just going to change the engine. from what u guys told me i should look for 90-93 lx engines,, two or four door.
i will probably buy the engine now and just put it on my car when the weather here in philly warms up. **** man i have been told $1000 for the engine change. right now i am saving about $700. lol by the way when i go to the junk jard for the engine,, what should i look for to see if the engine is good or bad????????

I ALWAYS use my sports mode on my car. and I notice no diference in MPG. Your right it does increase the time that it shifts to a higher RPM, but hell, thats a good thing. and if ther is any change in MPG it must be so small that it's not noticible.

 

thank u guys for the reply. now if u guys know any website of the honda forums out there that shows how to change f22a engine please show me the link. thanks
