Haha welcome to the site. Here is some info that might help you...

The model code is a seven digit code used to identify each model in the range.
This code is found on the VIN plate in the engine bay.
The following list breaks down the code reading from left to right.

Series code: G=Impreza S=Forester B=Legacy
Body type: F=Wagon C=Sedan
Engine type: 8=2.0L Turbo
Year code: A=MY93 B=MY94 C=MY95/96 D=MY97 E=MY98 F=MY99 G=MY00
Number of doors: 2=2 door coupe 4=4 door saloon 5=5 door sports wagon
Model type: 8= WRX 7= Type RA E = STi D =STi Type R & RA
Transmission: D=5 Speed Manual AWD P=4 Speed Automatic AWD

appreciate comments, and be patient andforgive my ignorance
so its a wrx, does wrx come with STI ? It definatly has and STI under the bonnet
cheers

yes the naifold is red and air intake mesh has STI on it, this can be seen through hole in bonnet

appreciate you input, thanks, will do as soon as the snapped rear cv is repaired

The GC8 sti’s had a red intake manifold and by the sounds of things it has an STI intercooler...

there are numerous things you can check but then again they can all be changed. EG:intercooler (i think GC8's didnt have the sti in big letters but a small sticker in the middle at the back), inlet manifold (red can of paint will do) alloy lower control arms, seats (sti enbroided), dash has sti written on the tacho i think), alloy bonnet, rear wing, all australian GC8's wrx sti's are numbered 1 through 400...1st batch came in 2 door and 4 door white and blue , second batch 1 through 400 only 4 door steel grey, blue and white....i might not be 100% correct
