Personally I think thats too much for a WRX! You can get a 2003 sti for 8-9K. Tax and insurance is roughly the same as well and the sti gets all the good bits.

 

Things to look for are gearbo syncros going, clutch and rear suspension.

 

Dont know where people get this idea that the engine is sh!t from?! Mine goes in, in 2-3 weeks and will come out running 450 (detuned to 420 for the track) on a standard STi engine. Thats not half bad for a 2.0l 4 pot!!!

That's the STi, there is a massive difference with the engine.

 

The bottom ends on the WRX are chocolate, they have to be built to put much more than stock through them. In fact, even the old P1's got into bother after 65k miles hence why they had to rethink the components used in the modern STi's.

 

A guy I know has a 450whp wagon and it had to be built from the ground up to hold that power.

ok, the older ones yes... the wrxs, yes... but thats like someone trying mod a NA supra to 450bhp and complaining when it breaks.

 

But agree with what you said now. 450whp is a fair bit!! I would not mind knowing the spec of that :)

The wrx is the 2.0 turbo,it's the base model of turbo impreza.

 

Graham I wouldn't run 450bhp through a standard block,it'll be a matter of time before it let's go,I built my bottom end to have 500.sti blocks are reliable to about 400bhp,gearbox will end it's live about 350bhp,I killed 2 before having a ppg box built

I didn't think the interior in mine was bad at all,had aircon electric everythin including sunroof,seats were like recaros aswell

 

Functionally it was ok, it was just a bit plasticy and old fashioned. Take away the seats and the aircon and it was like a cavalier iirc.

Experience!

 

For a start yours is an STI, which is a different animal to the one NOS is looking at, your bottom end will stand the increase in boost, assuming the mileage is not excessive and it's been looked after. With an oil cooler, regular oil and filter changes the stock STI bottom end will be good for around 380 - 400 bhp if you want reliability, anything over this and its a bit of a gamble. Have a look on the forums if you want proof. There was a member on here who worked for Subaru and was very knowledgeable. No-ones disputing the ej20 engines and it's variants are not good for high outputs for a 4 pot, more that there is a long history of high mileage wrx's dying when boost is increased and that the engine to go for is the STI, especially if like you you are going to up the power.

 

Out of interest how many miles on your engine?

 

The STI is a nice, seriously quick car with great handling, and has 4 doors to keep the missus happy, although the ride is very hard for a "family saloon"

After many discussions, with a couple of different tuners, people who 450bhp on STis, etc I decided that was the route. Car currently has 65k miles. The STi 6spd gearboxes are not bad, its the syncros that keep going.

 

I plan to use the car a fair bit on the track (especially considering where I live now :)) so, pretty much expect the engine to let go at some point... Not going to be silly with the mods and it will be mapped and maintained properly, but I do realise that it will not last anywhere near as long. When mine goes, I have my eye on a 2.1l kit which should be good for 480-500bhp mark which should be MORE than enough power to make up for my lack of driving talent :D

 

Completely agree - most people try to push the WRX engines way too far and obviously end up with expensive rebuilds.

Was meant to meet the Subaru owner tonight but we have postponed until Sunday afternoon.

 

He has assured me it is a WRX 2.0 turbo and that he fitted the FMIC himself, and not the previous owner. He also told me that it is not a Jap import.

Id be worried about that... From what I remember, its difficult, if not impossible to run a FMIC with the standard induction kit. Which means that it will cone style filter, which means it SHOULD be remapped!!!

I would value our 04 STI uk car at around 10K if it was stock, it has 34,000 mls but some very expensive mods, so 10k is way off.
