Am I just crazy, or what? Ej22 swap a fwd 3at

Hey guys, now at first I bet you're thinking that its a terrible idea and put a d/r 5 speed in it's place.

 

the car has 91k on it, its been garage kept since 1990, grandma owned, and when i bought it, the throttle cable was so loose it only opened the carb 1/3 way :lol:

im interested in economy, i don't plan on hauling rump roast off every stoplight.

the tranny shifts strong and feels like new. with the ej22 i think it would make this an excellent 60-70mph freeway road trip car

 

as the car sits, it weighs in at 2300 pounds, and it dosent have all the rolling resistance 4wd has.

 

how many miles do you think i can get out of this little 3at slushbox before i convert it to 3.7 d/r 4wd with rear disks?

 

:rolleyes: im guessing 10,000 miles

the 3AT gearing sucks for the highway, regardless of what's in front of it.

 

 

Nothing wrong with going for mileage, but a FWD 5MT is the way to do it. Especially one with non-turbo gearing.

 

Actually, a part-time 4WD transmission won't sacrifice much in mileage when in FWD. So don't put that out of your mind.

 

 

 

Also, time for my obligatory plea against the RX trans (3.7 D/R FT4WD). It's a terrible match for the EJ22 in almost any condition. I ran that combo for a few years, and it was definitely not worth it. So many other options that are much more common and much better in so many ways.

I don't know, but I would probably just make sure I changed it once in a while. Clean ATF will do miracles... IMHO, a tranny cooler might be a better way to spend money. Or just change the fluid more often. (notice a theme?)

 

I am serious, though, about cleaning/reworking the governor valve. Probably more 3ATs "die" from that then anything else. And I have a theory that the damaged gears that they get are often related to the valve itself being dirty, thus not sliding as it was designed and that leads to imbalance and wobbling of the whole valve assembly, causing gear engagement issues.

well, its the part time rx box. the thing is, the parts car with the tranny and pedal Assembly is currently being used, and i figure ej the 3at til she blows, then transfer all the 4wd and go fast goodies into the sedan.

Like an FWD 4EAT? Really nice highway gearing... probably get pretty good mileage out of that.

 

Numchux, sorry for hijacking your reasoned thought and corrupting it with slushbox thoughts. :grin:

ill defiantly change the fluid in the tranny. and putting a tranny cooler on it seems logical.

 

 

why im choosing the 3at, and such, is cause its already in the car, and re drilling a thin flex plate would be super easy,

 

as stated earyler i DO want to 4wd 5 speed swap this sedan, but i dont want to disable two running cars to make one :)

 

when the engine in the parts wagon leaves sometime in the spring ill take the 4wd parts, then :D

 

(parts wagon only has 110k on it)

So heres the progress on the swap, ive been sorting out the ecu and harness and its out of the car. there are about 5 wires that i dont know what to do with them.
