I'm thinking of trying to source a U.K spec Scooby after sellingmy WRX back in August.

The question is how can I get a u.k spec car upto 240BHP or even 280BHP, as after having a 240BHP WRX I wouldn't want to stay at 215BHP on the U.K model for too long.

You may ask why my preference is U.K, that is purley down to the fact that down on the South East Coast there's no one around that I feel I can trust for day to day servicing.

Oh! and I have a Subaru dealer's 5 mins up the road.

Also insurance is alot cheaper on a U.K car.

I seem to remember a dyno day some time ago where several UK spec MY98s were putting out in the region of 245BHP, with purely a backbox and filter change, running on SUL. That do ya ?

 

That easy eh!!!

Cool......

 

have not had mine on the rolling road but a decat exhaust, PPP ECU, Piper X induction kit and a full set of Billies with Eibach springs has worked for me and my mate with a 240 BHP WRX seems to think so as well.

For those sort of levels, you are looking at filter/full exhaust (at least one Cat less) and ECU, either UNICHIP or LINK to make the most of it. Just a filter and exhaust will make minimal differences if the ECU cannot use them to its benefit.
I'm not sure how much notice to take from the Rolling Road days, I don't want to open that can of worms again, best look at a standard scooby and look at what a modified one can do on the same day, then work out the percentage difference to give yourself an idea.
First thing I did to make mine go faster was to have bump steer mods and change the brakes :-)

 

Mine UK94 has been modified "just a little bit".

PiperX filter
Mongoose SS Exhaust (decat)
Apexi Boost Management system (10PSI 0.7bar lo & 19PSI 1.3 bar HIboost)
Apexi Fuel Management
Apexi BOV (sounds good ~ probably nothing else)
Cosworth Pistons (holed the Subaru ones)
Tarox disks and Mintex 1155 pads to stop the thing.

It was setup by a company in Warrington who took it far far as they thought they could w/o getting detonation. Further mods to get more power would involve fitting MoTec or the link ECU.

I haven't put it on a rolling road yet but hopefully will be doing so in Feb.

I've driven my mates Std 99 scoob then mine on the same stretch of road ~ they're a world apart.

Make sure you go for the 98MY as I changed mine for a 00MY and it was sooooo much slower (both standard). The 98MY had a bigger turbo I gather. I know it's not everybody's favorite, but surely Prodrive's engine upgrade would be best, if not cheapest.

 

"I know it's not everybody's favorite, but surely Prodrive's engine upgrade would be best, if not cheapest."

I disagree, I have recently had to make this decision myself. The performance difference comes from the ECU, would you rather have an off the shelf one size fits all, or for less price - a more sophisticated unit mapped by an expert to your engine specifically, if you then add Lambda and knock sensors you have very safe useable performance. The only thing that lets that down is warranty - my Dutch import MY00s will soon expire (the warranty not the engine :-) )

Have we covered this before ....

 

Scott,

Buy an RB5WR spec car. UK car with full warranty and same servicing costs as standard model. Comes with 237bhp and 258lbs of torque for starters, amongst other things I'm sure you can increase this if you wanted to

Last time mine was on the rollers, it gave 268 BHP and 269 lb ft.

MY99 + PPP + straight through centre section + induction kit

has now got downpipe and SS Backbox on as well

 

Put it on Power Engineering's dyno and you've instantly got 250 BHP !

Seriously though, check out the dyno page
