Are there any FAQ's?

[SubieNewbie]

I see people using letter and number combos to reference engines and such. EA18 or something like that. Has anyone put together a reference FAQ on this kind of stuff?

 

I'm a newbie and I'm looking to buy a brat. I'm not very well versed in Subaru mechanicals, but I am very familiar with the boxer engine. I've got 15 years in the aircooled VW hobby and know my way around them.

 

Any pointers for me as I go look at a few Brats?

Thanks!

Brat's were sold from 77 to 87 in the US, with a major redesign in 82.

 

77-81 are refered to as "Gen 1", and 82-87 are "Gen 2"

 

All 77-81 Brat's used the 1.6L EA71 engine, with the exception of the 81 GL, which contained the 1.8L EA81 and the new dual range 4 speed.

 

82-87 all have the EA81, and either the 4 speed dual range in the case of the GL, or the 4 speed single range in the case of the DL. DL's did not have T-tops either.

 

There's a lot more to it than that - I sugest a search, and a lot of reading on this board.

Hey thanks for the primer on Subies!

 

Has anyone put together a engine interchange reference page? Meaning a page that shows which engines can be swapped into which cars?

 

Specifically, can a complete EA81 or EA81T be put in a 1st gen Brat? Will it bolt right in? Or are we talking about modifying everything to make it work.

 

Thanks!

one guy has put an ea82 turbo into a gen one brat. mmodified motor mounts i do believe

 

i myself have out an ea82 motor in an ea81 car, it all fits the same, just procedure is different: "remove distributor to install or pull motor:

 

as far as what motors and trannies fit, all ea82 trannies fit all ea81 motors. later ea71 has the ea81 bellhoising. older ones(starter on top) can swap a bellhousing with an ea81, to use an old ea71 with an ea81/2 tranny

 

autos and sticks fitr in the same bodies each bodystyle without mods, just have the right mount, drveshaft, and final gear(diff) for the swap

 

2wds can be converted from auto or stick to 4wd auto or stick. everything is the same, but you will have to swap the entire rear suspension assembly(tube fram, traikling arms, diff,axles) also you will have to modify a mout for the carrier bearing, and drill holes for the diff hanger(ea82)

 

ea81 2wd and 4wd can be swapped with little mods(tranny tunnel), but all the 4wd rear end bolts up, the holes are there on 2wd for the diff mount, and 4wd uses a single piece driveshaft. you can also swap in 5spd 4wd from 4spd 4wd or automatics in an ea81, but you will have to make a mount for the carrier bearing

 

that is pretty much "standard" swap cross reference for 80's model soobs, ea81 and ea82

 

if you can find an 80 brat, or the front crossmember, it was designed for an ea81 motor. but the older crossmember can be modified slightly, (the steering shaft will be in the way) but around that, you can put an ea81t the same, if you get all the ecu/wiring, etc

Check out this post...Most of the information should be correct...I'm the moderator on this other board so, if it's wrong I'll change it!

To answer your question, yes there are frequently asked questions, like:

 

Where do I get Redline oil??

 

What is a LSD??

 

Can I install a XT6 engine into _______ (fill in the blank)???

 

What is the tranny ratio of a 8X BRAT???

 

This is just a few of the more common one, is there a place were these are stored?? Not that I know of. Oh, by the way, the answers are, I buy mine a B&B Auto Parts in Redmond, it is a Limited Slip Differential, yes you can, all it takes is time, money (lots of money), and a friend who is a fabricator, 3.90 unless it is a turbo, then 3.70.

and, yes you can swap a 3.7 lsd parts to make a 3.9 lsd
