and according to my transmission code - finding a match for chassis, engine, and transmission, i have a 94 STI first version.
the car came with the aluminum control arms, stock
if it is a STI, does the engine contain forged pistons?

I have the exact same motor and drivtrain going in my car.

Is there a number plate in the engine bay on the strut tower? There was a limited production of 300 Ver1's from Japan and all of them had a plaque rivited to the strut tower. Look here for pics and info.

Default plaque

hey-

i dont have a plaque on my firewall, or STI anywhere on the car,

but the transmission code and the engine code only match up to the sti v1. my intake manifold is silver, but so are the other sti ones.

car came with the aluminum control arms.

what gear ratio is my transmission? what rear diff do i need? im guessing a 00-01 RS 4.11 right?

I'm sorry to laugh, but this is the exact same thing I was doing for three months this summer, finding out what motor I have. Hopefully I can save you some time from having to do that.

Do you have a pic of the intercooler? They had different intercoolers for the WRX and STi version.

I have yet to get an official word on what the JDM final drive is. I have heard the UK version was 4.444 and the JDM is 4.111. I have seen else where the STi supposedly was 4.444 and the WRX was 4.111. I will count mine tonight and let you know.

Another thing is the alternator/ps pump cover has a "Handcrafted & tuned by STi" plaque on it also.

I couldn't tell from the pic but did you have IC sprayers?

Another thing you have to consider is the car is a 9 year old performance car from Japan, so the chances of it being modified or engine swapped are not to far fetched.

no intercooler sprayer. black angled intercooler. the trans code looks up to a 4.11 diff.
might have pic or IC, might not

no sti on anything. i dont think its been modded everythign seemed stock ex the aluminum control arms and mudflaps / orange corners. how do u tell final gear ratio from just looking at the trans?

The IC is from a WRX, the STi's were silver and the end tanks were larger. The STi's were actually just painted silver so the paint might have be taken off, just look at the end tanks to be sure.
This is the WRX.

And this is the STi


I don't know if the markings on the diff will tell you, but the 4.111 should have 37/9 gear teeth and the 4.444 will be 40/9. You will have to take off the rear diff cover and count them.

According to the seven digit chassis code you have a MY94, four door, WRX, 5 speed.

This is how the chassis codes work

Model Code: G = Impreza, S = Forester, B = Legacy
Body Type: C = Saloon and Coupe, F = Sport Wagon
Engine Type: 8 = 2.0 liter turbo, 6 = 1.8, 4 = 1.6, 1 = 1.5
Year Series Code: A = MY93, B = MY94, C = MY95/96, D = MY97, E = MY98, F = MY99, G = MY00
Number of Doors: 2 = Two-door coupe, 4 = Four door, 5 = five door wagon
Model Type: 8 = WRX, 7 = RA, E = STi (from version III), D = STi Type R and RA, S = 22B
Transmission: D = five speed manual, P = four speed automatic

There you have it. Since it is a MY94 WRX, you should have a 4.111 final drive, because they didn't switch the WRX final drive to 4.44 until September 1996.

Default solid deck

pre 96 was solid deck, the ej20G motors were. its a catch 22, the HLA heads have worse flow ive heard, and the HLA system is less reliable at high RPM, but the later EJ20K with solid lifters got open deck. - frankenstein???:P

I have heard that the EJ20G RA heads are supposed to real nice. It has different water jacketing, better valve material too. David Englishby from Prodrive said the RA street verion cars could out run the Group A cars. Mike Sheilds said the absolute best motor to get for a high horsepower EJ is the EJ20G RA.

The TY number is the begining of the tranny ID#. The black intercooler above would not be on a RA, but there is always a chance it was replaced because the original was lost in shipping.

Is the sticker still on the timing belt cover? All WRX's came with the TD05 the first few years except the GF8's that had the TD04.

GF8? what is that? I am not talking about STI version RA. I am talking about the WRX RA, and wouldn't that not have a silver intercooler, to my knowledge, and both WRX and RA have tdo5 in 95 that is where the confusion is. I will look at tranny code more clearly today and check timeing belt cover for what?

Ver 1s and Ver 2s had 4.111 the Ver 3 started the 4.444.
The compression ratio and hp numbers are the same with the ver 1 STi and the WRX.
Compression is 8.5 on your motor.
Your guess is about right 93~94 time frame you looking at 260ps. with about 31 kg of torque.
The tranny is a pull type instead of push try and get a Ver 3 if you got the cash it is a little stronger.
Look at the turbo closely is it a TD04 or an 05???
If it is an 05 your in luck because a nice little machining and larger compressor wheel will get some nice ponies.
I am not sure but your injectors I believe are between 370~420cc. Also if you want to get a cheap fuel pump and you can get your hands on it any Skyline pump will bolt right up with no prob even the connector is the same but it will be loud. You will not be able to mount a Ver 3 STi intercooler because the intake manifold will not allow it.
If your gonna change to a larger head gasket try and stick with a 1.1mm~1.2mm. Do not go to a Ver 3 which is a 1.5 because its to large.
If you have any other questions pm me and I will fill you in on anything I left out.

That is your tranny number correct. The numbers there provide all the information I need to get the numbers but then I have the numbers for all the trannys up to 2000.
Your code GC8B48D
indicates its a Ver 2
Engine Code EJ20GDW2HE
indicates it has a TD05 Turbo with 420 injectors

I was assuming that you wanted the numbers from the tranny the number you posted for it, is enough for me to find what type and what the gearing ratio is. The clutch release is pull type. I guess I am off if your looking for something different you have to explain it to me differently cause I am lost.

do independant tuner companies have VIN numbers designated to their specific models? Like would a Tommy Kaira tuned car have a special indication in the vin number or something along those lines?

edit: I guess this applies to other makes of cars aswell, would a mugen version of a honda have special insignia in the vin plates aswell?
