If a version 4 wrx is 280bhp standard, whats the difference to a sti to make 300bhp as standard power?

turbo?
boost pressue?
cams?
heads?
ecu/map?

Cheers

 

v4 wrx isnt 280bhp as standard mate,the sti is 280

 

as above think the wrx is around 240 bhp but may be wrong

 

Yea your wrong. They are 280ps and run a vf series turbo.

 

i thought the JAP SPEC WRX is 280, the same as a uk sti.its our uk wrx thats lower bhp.

 

We are on about classics, no such thing as a uk sti. The STI's run different cams, and ECU. Everything was supposed to be capped at 280ps as a gentlemans agreement.

 

version 4 wrx saloons are 276bhp wagons i think 240 but sti's have different turbos internals etc and they have a higher rev limit there are lots of other differences im sure as well check out the knowledge on the sidc website it gives more info

 

The entry level WRX(version 4) had 280 ps at 6500 rpm as std & 242 lb/ft @ 4000 rpm. The sportswagons as stated above had 250 ps @ 6000 rpm(up 10 ps on previous year) if it was a manual,if it was auto transmission it remained at 240 ps
One of the main differences was the sti version had substantially more torque than the wrx and also had a 7,900 rpm red line and a 8,400 rpm rev limiter due to having a stronger block & internals

 

The car im relating to is a WRX V4 GF8E58D 280 5 door.

Cheers for advise!

 

Your car is 'only' 250ps

 

From MY97 to MY00 all WRX saloons were 280PS (276bhp).

 

Ah yes, he has that weird anomaly wagon, where the power went up by 10PS, for that specific MY (compared to 240PS for MYs 97/99/00)

 

Joz the power only went up by 10 ps if it was a manual,auto's remained at 240 ps. , judging by his vin its a manual.

The version 4 sti did have 280 bhp,as per the gentlemans agreement for japanese sports cars( evo 6,nissan skline ,P1 - all 280 bhp),however it was rumoured that the sti was closer to 300bhp

 

Indeed.


Yeah, that old chestnut... but probably true. We love the Japs! lol

 

Have to agree with this if it's a wagon WRX(250bhp/225lbft). Only the 4 door WRX and STI saloon and wagon had 280bhp. Sorry to give bad news.

The version 4 did however come with a better rear diff than earlier models.
