nice list, sidenote:
4EAT= Complete Pile of Crap

 

Looks like we have quite a few T & TLA's.

 

i know its a lil off topic but i was wondering, curly is ur svx auto still?

 

Not in my opinion
And you base this upon?

 

It took me a loooong time to remember these abbreviations in my head. I only wish it was available at the time I needed to know them a few years back when I was getting into my Subaru.

 

sorry its so late, but then again i'm in the same boat you were 2 years ago...torc=total noob....but learning

 

thanks!

BJ = 1G legacy wagon, straight roof
BF = 1G legacy, raised roof
GDA =New Age WRX Sedan

BK = regular roof legacy 95'-99

 

I want a BJ!!!!!!!!!!1

 

thanks pidster added yours to the list

 

NOS I know is Nitrous Oxide Systems. Are all NO systems now known as NOS? Sounds like fallout from F and F.

 

this should be pinned.

 

thanks.. i will try and memorize these.. ^_^

 

hey! 4eat can take more BHP then a 5mt.

nice list. might wanna add some infr about the G / E engine codes. since those have been a hot topic. and maybe some thign about the 22B and how its the coolest car ever made (general subie knowledge).

 

VD?
STD?
F.A.G? (Fong's A Girl)

all 3 of those ones can be used in the one sentence... :laugh:

 

add a 7 to the engine list, that's the usdm sti block. EJ257 = 2.5L semi-close turbo

 

^^what are you talking about, Lue? It was in there!

Nathan. Take it to the "official Fong and Nathan" thread. :roll: :laugh: IIRC, I was the winner last. Now stop making excuses and sell me your x-pipe. :hs:

 

you wish you could win... by my count more people got coke up there noses or spit out their drinks on a keyboard by my remarks then yours... ha ha ha

about the x-over... we need to knwo for sure if it is the same as the 2.0...

 

Good list!!

Corrections:
HT - Heel / Toe ("Heal" isn't part of your foot unless you injured it)


Additions:
NA = Normally(/Naturally) Aspirated (i.e. no turbo)
PSI = Pounds per Square Inch (boost)


and... what's that custom-tuning computer or boost-controller thingy I always hear about? I can't even remember the acronym right now, let alone the real name...

And another important acronym to know:
VTEC = marketing hype used as a subsitute for superior boxer design =)

 

DSM - Diamond Star Motor
POS - Dodge Neon

 

wait, it's in there? i didnt see it before!

 

are you thinking the PP# = Perfect Power version # (ie 5, 6, or 7)
the Cobb AP = Cobb Access Port
TXS UTEC = Turbo XS someting or other. its a EM unit.
TXS DTEC = Turbo XS DTEC (i dont know what that means, but it uses a gameboy)

 

no EA or ER motors?

 

I disagree. Why do you think this?

 

EJ22E = N/A 2.2L
EJ22T = USDM 2.2L closed deck turbo
EJ20g = 2.0L closed deck turbo sold over seas

22B = I don't know with the closed deck phase 2 motor:dunno:



IAC = idle air control valve

 

IIRC, the 22b uses a EJ22G motor, which appears to be the EJ22T with DOHC

anyone know the codes for newer legacies? like my mom's '01 L sedan?

 

User Tuneable Engine Computer

 

The 22B motor is closed deck like the EJ22T, but it is a phase two design, meaning it uses an end-thrust bearing, as opposed to the center-thrust, and has the updated oiling system, since there are no oil squirters.

 

22B is not an engine code, its the actual name of the car. It's called a WRX/STi 22B. The actual engine code is EJ22G, which is only used in that one specific car. It is a bored out 2.2L EJ20G closed deck motor from the early WRX/Liberty RS with different heads.

 

Ahhh, okay, so my '00 2.5RS is infact a GC6 with the EJ25. I knew the engine model but the manufacturer code for my vehicle I was unsure on. Seems that everyone just wants to call them GC8's, even if they're the 2.5RS.

 

And you base this upon?
-having one in the SVX, not that bad, just weak...
curly is ur svx auto still?
-Unfortunatly, yes

 

Bump56

 

hey...what about WRX..???..what does that stand for..???

 

WRXs are GDB, or GD8 depending on the site or person. WRX stands for World Rally X(Cross), or World Rally X(Cross Country) on some of their early brochures that I have seen.

 

So do the new WRXs have the same EJ255 motors like the Forester and Baja?
