probably been asked a million times but i just cant find general info on this.

Taking a standard 95 v2 WRX (what i have) V a 95 standard STI

what does the STI have that the WRX doesn't.


CHEERS.

 

Slightly more power that's about it I think

 

theres hardly any diference the only thing is peak torque is lower on the sti than the wrx

 

Apart from the..

Alcantara STI seats
Red stitch steering wheel
Red stitch gear ****
STI badged clocks, with 7.5k red line
STI badges on the wings
Carbon strut brace
"Tuned by STI" badge on the belt cover in the engine bay
Forged pistons
Slightly larger intercooler, silver and STI badged
Mid level spoiler (option on the WRX)
Different ECU with higher boost level
Pink badge on the front grill
Possibly different wheels (can't remember)
Might have intercooler water spray (can't remember)

Think that's about it.

 

great responses thanks.

in terms of engines one would of been closed deck and the other not? 260ps to 280 ps?

been researching impreza models and theres so many differences all with different specs its too much to take in.

 

Wrx of that time got 260ps and the sti 275. As for CDB, that was the time when they were being phased out, they may have though.

I actually owned a 95 wrx a few years ago and a good pal owned a sti V2. We went head to head at the pod, I lost by about a second.

Is your friends car a my95 or my96 car. As the only STI available as a my95 was the sti ra. The sti v2 (which was actually available late 95) was a my96 car.

 

ok, my mate hasnt got a sti i was just making an example on paper.

ok so what gave the sti the 275ps then? ecu or turbo setup?

my wrx has the tdo5 turbo. what ecu would the sti use, 6k?? as opposed to my z4.

 

Off the top of my head im not sure what ecu the sti used.
Turbo's were the same but the sti ran a bit more boost i believe, it was obviously just a little more tuned. The intercooler was also improved on the sti.

What are you trying to achieve ?

 

im just trying to find out what was different on the sti's in terms of engine and gearbox specs.

i hear people talk about a redtop sti, im assuming this was a later engine was it?

 

V3 STI was the first to get the red inlet manifold.

There wasn't really a MY96 WRX as such - The MY95 and MY96 share a model code as they are exactly the same. I would presume they just carried on knocking out the same cars for the start of 1996 to use up the parts they had before releasing the face-lifted MY97 towards the back end of 1996.

 

My own STI V2 and my pals both had red original crinkle painted manifolds.

Yep, both the 95 and 96 wrx are the same. The STI however was different as the my95 model was only available as an STI RA. By the my96 the STI V2 was released.

 

the turbos are the same (td05) the only difference is the ecu (sti used sa, sb, sc) and heads, they were slight different to allow for the higher rev limit. some wrxs had cdb also.
