what makes a wr1

[steff109]

what modifications did subaru make to the wr1 above an sti to get the extra power ?

[marky mark]

Removal of the pre-cat in the up pipe, change the DP cat for a higher flowing one and a remap to suit with a bit of extra boost added in.

Think of it as a higher spec PPP.

I think they added a 3-port boost solenoid as well for better boost control, whereas standard STI PPP has 2-port.

...and don't forget the WR1 stickers - they add at least 10bhp, lol.

Trust the bitter P1 owner to understate the superior WR1!

Plus an uprated fuel pump

Eh? Where am i under estimating?

ok great stuff can i take it then that the car is already mapable then and does not need a transfer ecu

The current ECU is "re-mappable" usually "ECUTEK" is the system used.

Depending on what Bhp and mods you fit the current ECU is more than sufficient.

add an adam to your car wr1 - makes it about the faster car in the contry, and defo the most sideways...

...not sure how much subaru charge for the mod though, or whether or not you have to declair it

Thought all Sti's had 2 cat's, downpipe and centre section, up-pipe is already de-catted....WRX do come with the 3 cats though

PPP removes the downpipe cat for a better one and takes off the centre
section and replaces it with a de-cat stainless section

So WR1's just come with the ecu prodrive map, sports-cat downpipe,prodrive exhaust system, triple port boost solenoid, ppp fuel pump, to get that extra 11 bhp over a standard STI ppp,

Along with Prodrive lowering springs, 1mm shorter rear drop links
(according to mike woods ) it's on here somewhere! plus the other visual stuff

and of course cornflake wr1stickers
