Complete power loss!
Hi Gang, I'm after a bit of advice please? My car (97 WRX Wagon) has developed a bit of a problem. When flooring it and hoping for max boost the car has started to offer a less clean, smooth boost, infact the problem started out as a suttle though noticeable repeated surging as the revs built and only after the Turbo kicks in. This happened for a day or so but now manifests itself as a complete power loss. The best way to describe this power loss is to compare it to the one experienced when the car redlines and cuts out momentarily before powering up again after the revs have dropped.
Any suggestions as to the problem (Maff, boost???)would be much appreciated. PS. I had ragged the motor the day before these issues began to appear.
Many thanks in anticipation.

You should be using super unleaded only really, they dont run very well on unleaded, it can kill the engine 
Oh and it could be that you dragged the crap out of the bottom of the tank if low on fuel

Definitely give the removal of the MAF a go.
Its very simple. Just unplug it from the cable it is attached to and if the car runs smoothly you'll know its the MAF.
I had a similar problem where my engine actually cut out after hitting 1500 revs. It turned out that water had gotten into the air filter and the MAF went into limp mode and cut out. Removed the MAF and the car ran fine again.

to add to what tony has said, also check your igntion side of things as it sounds like either fuel cut or limp mode. What revs does this occur at? if it is around 4k then its limp mode, if it goes over thatbut feels sluggish then my thoughts are that it is going to be ignition related - either plugs - coil packs (cant remember if a 97 will have individual coil packs or 1 shared, the individuals are weakened with age).
If its recently come across from japan then a good service would be the first thing I would do

Power loss
Hello mate,
Not a sccoby owner for a couple of years now, but if your engine is still revving ok, do have you a boost guage fitted. If so, is it boosting normally ?
You could have a leak from the intercooler, which you have made worse with your spirited driving, up to the point where there is no real boost pressure, and a major power loss.
Do you get a whoosh when you put you foot down and find no power ?
All other suggestions made so far very valid - just adding another option, and if it is this, an easy / cheap fix.
As stated, Super is the way to go - I would also change your fuel filter as a minimum (under the bonnet (do it when engine is cold )
Good luck,
Mart.
