Hi, I've got an euro-spec MY2006 (pignose) 2.5l WRX that's been remapped, has a K&N Tornado intake, decat downpipe, Cusco anti-roll bars.

Am currently looking to improve the power, hence the questions -

1. If I switch from my TD04 to VF34 turbo, will I need to change my decat downpipe (will it still fit ?) or anything else - besides another remap ?

2. Do I need to change the injectors, fuel pump, fuel regulator on my 2.5l WRX in order to achieve more power ? This has been very controversial - had answers ranging from no need to change, to no need to change injectors to only need to change fuel regulator.

Any opinions ?

Thanks - SH

1. Keep the decat - yes to the remap.
2. Your injectors are already the 505 cc/min so no need to change - the hawkeye (pignose??) WRX & STIs share the same injectors unlike previous models. Yes to fuel pump. No to fuel reg.
