Default what are the gear ratios?

So the bugeye wrx shell we picked up is manufacture date 4/02, and has the stock (5spd) rear diff still in tact..

Apparently the 2.5rs motor and 5spd trans my friend pulled came from a bugeye with a manufacture date of 1/01 (which by the date I woulda guessed was an 01, not bugeye but apparently he took the headlamp too lol)

Long story short I just don't want him to put them together and find out the hard way that theyre a different ratio..

the trans should have a pn tag on it.....post that number....the first 'bugeye' was sold in the usa as a 2002 my car.....in japan(and aus and nz) it was their 2001 my...japan is weird and their model year is a year 'off' most of the rest of the world....which is why they use the body codes to differentiate model years
the first bugeyes sold in the usa had build dates 12/00 and 01/01...a friend had one of the first wrx's made and sold in the usa....its build date was 12/00 and we concluded that it must have been some sort of 'test' vehicle as it was a mish-mash of 'gc' and 'gd' parts and its ecu pn was not listed anywhere and could not have its ROM read or be flashed and it was a beast....

if the trans is an rs and not a TS or OBS...then it is almost certainly 4.11 and you are better off finding a rear end out of an automatic trans bugeye wrx which has lsd and 4.11

the 02 wrx rearend is 3.545 and is kinda useless without a 2.0 wrx trans

Okay so how about a 2006 (7/05) wrx m/t ratio? I still dont understand why this guy chose the 2.5rs drivetrain instead of the 06 wrx right next to it.... but apparently when the salvage yard was transporting the motor/trans to the front gate they dropped it... so I cant even be sure the motor or trans are even good at the moment he said it dented the oil pan, damaged the alternator and coil pack.

Worst case scenerio Ill peer-pressure him into pulling the wrx setup and well get everything to match it. Hes talking about boosting the 2.5rs motor but why not rebuild what was already designed and tuned for boost? I know, wrong category just ranting a little..

The 01 2.5RS rear diff, manufactured between Sept 2000 and March 2004, has a 4.11 gear ratio.

So, if you have a rear diff out of an 02WRX, then these won;t work together well.

You either have to get a matching transmission or matching rear diff for whichever part you want to keep

Yea, thats why I commented about the my06 m/t gear ratio, to be honest Im at the point of whatever needs to be replaced we can replace. Only thing were not looking to give up on is the shell, but if we need a different trans we can get a different trans, if we need a new differential that can be done too.

you do NOT wanna get into trying to boost the non-turbo subaru motors

they usually dont last long.....hell even the turbo ones dont last long in the hands of idiots

the 06 wrx is 3.70 in the trans with a 1:1 stepper and a 3.70 rear end

damn FHI to hell for doing all that stupid **** with these ratios

So then were pretty well dead in the water huh? I suppose its for the best, I took a look at the motor/trans last night... it definitely dropped hard the oil pan was pushed in pretty deep. I dont doubt theres damage and thus it should be torn down and built from scratch. Id rather have the wrx motor..

pick up a JDM clip/drivetrain and swap the motor, trans, rear end, brakes, suspension, lower control arms, etc.

As much as I agree it would be badass to have a full jdm setup.. I know a guy that just spent roughly $3500 on a "jdm turbo motor w/ 6spd trans, less than 50k miles" waited a few weeks for it to come from overseas. When it finally came in, the harness was chopped to bits, the 5spd trans was stuck in 4th (wouldnt budge with a sledge hammer) and a sticker said the timing belt was changed at 92k. I know its only one incident but I just feel safer buying what I can put my hands on.

Not to mention, when he tried contacting the company to return it due to the condition, they said theyd give him a full refund but he had to pay to ship it back, overseas freight was like $1400 (according to him >.>)
