there is a group buy on ballistic cats on ff.au in the boss section, may be worth jumping on that.

other than that, what you have listed should see at least 330 at the treads.

How do the ballistic Cats rate and what is the size required to weld into the standard cat position? Is it 3" or 3.5"?

Cheers

they are 100cpsi so should be the pick of the bunch.

they have a 3" in/out 5" body one in the range which would be good.

most metal cats are 200cpsi (cells per square inch) so the lower the better!

m6xr6t has them on his new ute and seems happy with them. there is a pretty big thread over there about them.

What do you guys think is better. 3" or 3.5" inlet and Outlet on the stock dump? I am now a bit confused as there are some running 3.5" also.

3.5 would be the go if your goin to up the power ,as far as fuel pumps you can't beat process west set up ,a bigger pump will give more fuel , but doesn't help with any surge issue's you might get

and the V2 is very quiet don't even know it's there

350rwkw will be fine with an in tank Walbro on a ute Adrian :sleepystuff:

As far as dump/cat, for the extra bit of cash I'd be getting both to put less stress on the engine when making power & improve spool up! I'm thinking of selling my SMB 4" dump/cat to go with a full exhaust so I'll let you know.

Dont stuff around.......4"dump and 3.5"min in out cat(4-5" body) in to either 3.5" or twin 2.5" exhaust, 60lb injectors, v3 or 3.5 kit from rapid, larger fuel pump( if you can afford it go external with surge tank as they are simple to install in the ute insted of droping a tank or drilling spot welds) this will give you 350rwkw but you may have boost issues (I dident). Porting and flapper mod on the turbo is a good idear but not critical. If you do all these you will get 350rwkw on 15lb of boost and it allows you to wind it up a few pound more later if you want. Another good item to have is an electronic boost controler, at the press of a button you can go from say 12lb of boost to 15lb of boost on the fly or 225rwkw to 350rwkw.
