Is AWD the same as 4WD?

What is 4EAT?

Can I just bolt the 6 speed in?

What are the different gear ratios used by model, year and transmission used. I know I've wondered about those when looking for a used LSD before.

Oh and how about that old link we used to have for the online tire size guide. Where you could enter in your old size and the new size you want to run and it would tell you how close it is to stock by percentages.

Do I have an LSD

What is an LSD

hmm I think of more :p

and why not to do it...

Why does my transmission get stuck in second gear when I aggressively ascent twisty canyon roads?

I'm actually being serious here...

Clutch/ Flywheel info:

who makes them for our car?
why or why not get a stronger clutch?
why or why not get a lighter flywheel?

Bushings info:
shifter bushings - what they do & reasons to get or not get them
hardened tranny mount - same as above
hardened rear diff mount - same

Please post what you think is a FAQ."I'm content with my stock WRX's mid-14 second E.T.s. Do I need to upgrade to the 6MT, or is this overkill? Does the greater rotational mass inside the 6MT and attending drivetrain power loss negate the advantage of durability potential?"

note: Maybe the above isn't very frequently asked, but I wonder how I can make an informed decision on whether or not to spring the bucks for the swap.

Down Shifting.
Is it hard the engine, transmission, clutch, to down shift? (not necessarily when entering a turn but I know people who say they downshift when breaking to slow there cars for the purpose of "saving their pads.)

what is double clutching?
what tranny oil does the WRC car use? (it's Neo Synthetics BTW)
Why is it hard to shift down into first? (syncros worn out, upgrade fluid and learn to double clutch for the track)
How can I fix the power gap between first and 2nd gear? (upgrade to 6speed, or get a new gear set with 2nd shorter, about 2.00-1 and 1st taller about 3.00-1)

Turbo and High performance Mag has a great WRX tranny section this month!

Do the 2003 wrx have the same clutch and gear problems as the 2002?

what's a good short shifter?

What are the details of all of the Subaru drivetrains, to include every single Impreza (2.5RS, WRX, JDM STI (all versions), USDM WRX), forester, Legacy, and SVX.

Ratios:
Parts composites (which version's parts are stronger than...):
Parts dimensions (Which parts are shorter/longer than...):

Maybe, who are the best retailers who consistently get engine/drivetrain parts at low cost for i-club members.

Along with that, what are the effects of differing ratios on speeds, gas mileage, how each optimizes available torque.

Personally, I can read the ratios, but I don't fully understand the differences until I can either drive it or if someone breaks it down for me in language I can understand.

originally stated by gpatmac
I'm not a smart man, but I know what torque is.

Post a link to this site.
http://auto.howstuffworks.com/gear-ratio.htm
It explains fairly well what gear ratios mean overdrive, direct drive, and gear reduction.

Actually just a link to the site in general might help.

What if anything does the STI group N pitch stop mount do?

Whats the difference between the Kartboy short shifter and the STi one?

Who makes lightweight driveshafts for our cars?

What parts do I need to do a 6sp swap into my WRX or GC8 RS?

-DE

Why does the tranny suck and what can I do to make it stronger/better/more reliable?

What should I do in cold morning starts?...pumping the clutch...etc

What is good engagement rpm for calm street driving?

Can you replace separate gears and separate syncros?

where are the answers lol

What is the most whp that can be launched with out damaging a tranny?

i think there should be some information on 5 speed symptoms and solutions. There are a lot of people having trouble with clutch judder (jerking), syncros (grinding) shifters(short throw vs. stock) bushing mounting upgrades to make the 5 speed better for us out there. what is the best fluids to run ie. tranny brake fluid, rear diff(all with solid result notjust opinions. Also making sure that people know what the factory warrenty 3/36k on everything 6/60k on drivetrain. How to haindle the dealer and make sure that we get what we waint (within reason) cuz we know we all paid a pretty penny for our cars. hope this helps.

What's a good clutch/flywheel setup for EJ20'd RS's still using RS tranny. Who makes a complete replacement kit (pressure plate/ cover/disk/ bearings etc.)

Where can you get parts for clutch swaps IE throw out bearing, and alignment tool when not included in kits such as ACT or SPEC.
Are they OEM parts or specific to each clutch setup?

what gear oils to use in tranny/differential? weight/brand?
and how many quarts/litres to buy.

Sorry to bring a dead thread back up, but are we gonna get answers? :)

What clutch/flywheel do I need for _______ engine swap...
What clutch/flywheel do I need for _______ trans swap...

*The unconfirmed answer I have found*

two basic clutch arrangements
push clutch/pull clutch

one for turbo imprezas one for non-turbo (cant remember which)

you cannot mix non-turbo clutches and flywheels with turbo transmissions. So match Flywheel and clutch with transmission..

This is all unconfirmed because I have not personally done any of this and I have only found one source so far supporting it.

You should have every answer what they think a good answer would be to their own questions so you can take the good ones and use them
