EA81 4sp D/R to ?? trans swap

[Zebisko]

Ok, I've finally started to get out of the red with my money, and as genuine as double-clutching is, I am sick of it:-\ . So what better to spend it on than a 5sp transmission! Now what I'd like to know, is what is the most reasonable trans to replace it with, and what I need for that swap. I'd like to keep the D/R, but don't really care too much. Thanks much in advance

 

 

P.S. I have a 1984 GL Hatchback Diamond Edition with EA81 4sp D/R:burnout:

i know who knows, you need to talk to brat avenger. i believe he did it on his brat. i was talking to him cause i wanted to do it on my hatch.

You could convert to an EA82 5spd D/R. There's an article in the USRM on it. bratsrus1 (Jerry) makes a kit with a modified crossmember that allows you to not need to bang the tunnel, and will modify your shift linkage.

 

Alternatively, you could go for a 5 spd pushbutton 4WD, or 5 spd FT4WD S/R, or the ever illusive, 5 spd FT4WD D/R (though the low range isn't very low... Kinda crappy really).

 

You have a lot of choices. Your best choice would probably be the 5 spd D/R from an 85-89 Wagon.

yeah i would definalty go with the Ea82 d/r 5sp.....my cousin (jibs) did the swap on his brat and the thing goes like a champ. road trips are great in it because you can just cruise without revving the hell out of your engine. and i believe it helped his gas milage too....just check in with jerry (bratsRus1) and he should square you away with a kit

Thanks for all the info so far, I appreciate it. I have another couple questions though. How does the FT4wd tranny work? Is it always in 4wd, or is it selectable? And how does the D/R on the FT4wd with D/R work? If anyone is up tonight, I will be too, physics lab report due in about 11 hours, and workin' on the danged ball joints again in about 8. Hopefully I'll finally be done with that(Broken clamp bolts=huge hassel). Well, enough procrastinating, I'll get back to work on this thing.

Physics is not fun. I've had to take intro level courses in Mechanics and E&M. Not the funnest of classes. I feel your sorrow.

 

The FT4WD is in 4WD all the time. FT stands for Full Time. Its got an open center differential with a switch to lock it. Kinda nifty I guess. The FT4WD with D/R has an extra lever to put the transmission into a lower range. The low range on it kinda sucks, but it helps.

 

The largest difficulty I can see with putting an EA82 Turbo tranny in an EA81 is the axles.

Pah! High School physics is easy and fun. Try college physics w/calculus if you want to be confused. At least it was open book.... not that it helped much.

Didn't realize he was taking high school physics HS Physics was a breeze compared to calculus based Mechanics and EMAG courses in college.

That's what I thought about the FT. I'd probably end up just trying to find a PT4wd D/R 5sp. Thanks for the info!

 

P.S. This is my second year in this Physics class, as luck would have it, I have the same teacher. Oh well, she's pretty cool. I am hoping that I can keep my study habits improved, so as to pass this class in the higher grades, instead of like last time(*cough* F *cough*).

 

P.S.#2 Not so easy when you are a lasy(oops, meant lazy) sloth with a hard-rump roast for a teacher

 

P.S.#3 What about axle ratios? Are they all the same for these years, or would I have to look out for a certain one? I know I have a 3.90(I think, should be same as rear dif, right?)
