Oh yeah
350bhp and a forged engine... Hilarious fun
Looks fun!! I keep toying with the idea of tickling my WRX wagon - just a prodrive backbox (for more burble innit!) on it at the moment. It's done 119k miles now but runs lovely and sweet + 30/32mpg. I wonder if I go the remap and full exhaust route will I lessen the life of the engine and ruin the mpg?350bhp and a forged engine... Hilarious fun

Drove Munich to Reading yesterday
780 miles at an average of 31.3 mpg using ARAL102ron
Great effort! I've done an 8 hour drive in mine and still felt fairly fresh, they're pretty comfy in standard form I reckon - the shape of the seats help 780 miles at an average of 31.3 mpg using ARAL102ron
Some of you are getting brilliant economy! I've had two Imprezas, the latter is my current car. Both blob-eyes, both modified.
'04 Type UK STi PPP, K&N panel filter, SC38 turbo, Milltek cat-back. Did 17-22mpg (24mpg nursed), 80% motorway, 15% urban overall.
'05 Type UK STi PPP, rotated intake, GT3076 turbo, Milltek turbo-back. Does 16-21 mpg (22 nursed), again 80% motorway 15% urban. In stop-start traffic it might get down to 15mpg, on track around 8-10...
ETA: (FTFY )

All true. The standard turbo is pretty good and freer breathing should help efficiency. Craivold I wouldn't necessarily worry about engine wear per se:
- if the engine's fine to start with
- the mapper knows what they're doing
- so long as you get regular oil changes (done by a mechanic who knows how to prime the galleries),
your engine will be just grand. Just don't ask the mapper to wring the nuts off it!

My RB5 was previously running a TD04, sports cat, prodrive ecu on a forged engine and achieved 22-24mpg on the run.
It's just been converted to a Twin Scroll (VF37), Equal length headers (for twin scroll), 550C injectors, Miltek exhaust, alcatek ecu and a bunch of other stuff and now does 30mpg on a run.

Cheers for the advice. Very tempted to get it done. Got a wedding to pay for first though... - if the engine's fine to start with

I've never had one mapped until late last year and with the upgrades my car is completely different.
