Thanks for that info - my main reason for asking is that I have a JDM 2002 WRX, Bug eye NB-R and I have found the original sales bumf - it states it has a " 2.0 Boxer DOHC 16 valve AVCS Turbo" engine.
Was AVCS added to this as a "special"

Good question mate,
great if they have been added, I was going to fit some in mine but it meant splicing the loom etc, for roughly the same price I'm just having my WRX ones ported.

overall, including the 2.5 STI block, forged rods pistons etc, about 500bhp
will have to get a turbo and FMIC to match though, they are in the pipeline, my funds are getting quite low at the moment though.

I thought the same mate, but i kept pushing and pushing, eventually the engine blew up, the car has been off the road for almost a year now
Taken me this long to save up for the parts, then I started getting paranoid thinking that parts that I wasn't intending to uprate might fail so I uprated them too.
before long I found that I could have bought a decent newage STI for the price of the rebuild
looks like me and the Subaru have to spend the rest of time together

The NB-R was a a bit of a hybrid
Lots of STi bits (mostly suspension) on a Bugeye WRX. As it has the Bugeye ECU I'm not sure it could cope with AVCS
A bit of a rare beast and I can't remember who had one on here !

Rally Fan 555, I've found a bit of info on your car, looks like the AVCS was fitted as standard on it lucky git.
[edit] Japan-Spec
[edit] Rev. A (2000)
August 2000 brings the 2001MY WRX NB sedan. It has an EJ205 with AVCS coupled with an MHI TD04L turbocharger. The engine produces 250 PS (184 kW) at 6000 rpm with 34 kg·m (333 N·m) at 3600 rpm. The wheels are 16-inch (410 mm) in diameter. The car uses 2 pot/1 pot front and rear brakes. The front brake rotors are ventilated while the rear are solid disks. It has a torsen rear LSD and a 4.44 final drive ratio. The transmission has close-ratio gears unique to Subaru of Japan at that point in time. The car has a curb weight of 1,340 kg (2,954 lb).
[edit] Rev. B (2001)
The 2002MY WRX NB sedan debuts on September 2001. The mechanical specifications are similar to the previous year's model but the curb weight has been increased to 1,350 kg (2,976 lb).
[edit] Rev. C (2002)
The WRX NB-R sedan is released on November 2002. The power and torque ratings are the same as the previous year. The wheel diameters are increased to 17" in size. The rear brake rotor is changed to a ventilated disk, leaving the car to use only ventilated disks for braking. The car has 4 pot/2 pot front and rear brakes. The rear wing is on wing risers. The car now weighs 1,361 kg (3,000 lb).

I had such bad luck with it though, I was having a heated debate with the other half, mid argument I changed from 4th to 1st instead of 3rd and blew the gearbox up!!!....clearly her fault. Anyway I though I would use the opportunity to put a 6 speed box in, which I did I then re-kindled my love for the car after a nice remap and decided to completely change the outside by getting carbon bits and a full respray on my way back from the paint shop some lad in a Civic Type R thought he would have a try, stupid kid... I thought and down went the foot.....10 seconds later a rod shot through the top of the block......been off the road since.

The 2.5 WRX does indeed have AVCS heads. They are AVCS on the inlet only.
They are also believed to be better or bigger power due to slightly higher compression ratio but its negligable.
I have just bought a 2006 2.5 WRX engine for that very reason. They also have shimless buckets which means you can run a higher rev limit.
I'll only be using the cases themselves as I shall be replacing cams, springs valves and retainers for a combination of cosworth and supertech items.
Will be using a front Mounted GT35R with reverse inlet and these heads on a strengthened 2.5 Engine. Aiming for circa 600bhp when its all bolted together.
These heads are a very good base for any build but you will need bespoke ecu and extensive mapping work.

I was under the impression that ALL JDM Bugeye WRX's had AVCS and that that is what gave them the higher output (247bhp) than the UK cars (217bhp). I used to have one and it was significantly quicker than a standard UK Bugeye WRX.

Cheers for that Shaun - I had her from the Midlands, I think the previous owner went by the name "Captain Caveman" on here
I wonder if the AVCS will make mapping a prolem as it's a future plan for me
Si.
