Euro 4 compliant FG's running stock cat can push high numbers without gutting anyway. What year is it??

Torque its where its at fellas .................I think a free flowing exhaust and dump will yield a lot more torque, which is what we love about these cars.

rwkw are for dyno days only :nyaah:

Maybe Ford put the restrictor ring in because the Euro4 cats flow too well.

well in the case of the stock turbo the euro4 cat/exhaust flows enough, I am not to sure you will make that much more torque replacing it imho. the turbo will run out of puff regardless which mod path you take.

bang for buck for maxing baby turbo and almost 500hp sleeper

pump ~310-325rwkw @ 730-760nm

e85 ~ 345-357rwkw @ 880-910nm

357 is a precise number you say? I have seen 4 members with various upgrade paths all end up the magic 357 number running e85.

- ID1000 Injectors

- PW Stage 1 or 2 Cooler Kit

- PW Dual DW300 Surge setup

- E85 Fuel filter

- Remove restricter ring

- Cut hole in bottom of air box

- K & N air filter

- Valve Springs (situational, some cars get valve float)

- Xcal 3 / Tune

I love how it's always the sh*ttest, ugliest, most bogan Holden's that have anti ford stickers on em. Not exactly helping their cause.
