WRX or WRX STi?

[SnackobSnazell]

Hey guys, I'm relatively new to subaru's and want to know what the differences are between the WRX and WRX STI. Specifically the blobeye generation 2L  EJ20 as I'm planning on buying either or a WRX / WRX STI. 

Cheers 🙂

Wotcha and welcome - From what I remember when looking at a blob / hawk sti there were quite a few differences, particularly in the chassis area.

I stand to be corrected but here goes:

turbo - bigger on the sti

Intercooler

ARB's are thicker

Bearings are larger - as such pcd is different

Some chassis parts are alloy - lower wishbones?

possibly different brake calipers - not sure on that one

Probably a few more things - possibly struts and springs

There's quite a few differences in spec between wrx and sti blobeye spec , hence the £4k + price difference.

Although the wrx is a capable car , that does its job and is easily unable to around 300hp . it  has 5 speed and non forged engine .  So if you're aiming for over 350hp ,the sti is a better base .

Sti has sportier interior and suspension . Brembo brakes , stronger 6 speed gearbox , stronger forged engine (450hp capable) ,tmic waterspray, bigger turbo and injectors as standard .

Theres also the widetrack ,wr1 , spec c , spec d and a few spec differences between them too .
