Prodrive sports cat
prodrive backbox
green panel filter
walbro fuel pump
With the above fitted would it be ready for a remap ?
The car in question is an 04 WRX
What increase could i hope for?

 

Walbro is not necessary at this level, you will find your turbo and injectors are the limiting factor - you should see about 265bhp with 240lb/ft from a good map

 

its my wallet thatsthe limiting factor.

 

You can get around that, it's your imagination that's the limiting factor

 

I'd say nearer to 280bhp + similar torque , with a tek 3,

 

Who are you going to get to do the remap?

 

just had mine remaped by duncan @ racedynamix. best thing i ever did. i have a 3" inch turbo back s/s. Do-luck filter. spark plugs and sti up pipe (thanks harvey) and i goes like nothing ive ever had. my wallet was streched but like duncan said after finishing the map whats next. my reply was nothing thats slowly changing.... good luck hope you enjoy it

 

Powerstation are on my doorstep,JGM seems to get very good reviews.Richie where were you thinking of?

 

Bob Rawle did mine,Top guy and he's in Swindon.He maps on the A419 between Swindon and Cricklade.

 

In Total Impreza there is a company called "scoobyprojects" i was going to have a chat with them they are in Ledbury .

 

Never heard of them.

 

You'd be as well going to Bob Rawle, and check out the group buy section for a good price at the moment

 

If i fit the prodrive sports cat will i need to add any other bits to the exhaust system?It already has a Prodrive backbox.

 

It is not essential, but it would be worth looking for a 3rd decat pipe to remove the final cat (something like this one - https://www.scoobynet.com/private-fo...ecat-pipe.html, but this is now sold) if your car still has this cat. Also you can remove the centre box and get a resonated or straight through centre pipe. It is not worth going to a 3" bore with the rest of your system being 2.5", but these will be the biggest restrictions in your exhaust if funds allow you to make the changes. Check out Cobra exhausts for a good price on stainless steel replacements - they are in one of the trader areas
