I have uprated my brakes so you say about the clutch what gains will I get from that and what would you recommend ? Also would you say clutch before turbo ?

Clutch wise when/if needed...a Exedy pink box clutch would be more then enough to cope with 400+bhp/torque,but if your clutch is not slipping I would not worry about it until it gives up,you have already done the sensible thing by upgrading the brakes before adding more power.SJ.

Iv still got the standard turbo in the car is that a td04 ? Dont mean to sound clueless but I’m pretty new to all of this ! I would like to get up to 400 bhp with good torque what would you suggest and would I need to do any thing else to the engine so it could cope with that sort of power ? Thanks for your reply

I’m looking at spending around 1500 but would spend abit more to reach my goal of 400bhp but also don’t won’t to push the engine to much and start having problems with it ?

Unsure if already mentioned, but let's assume you need to spend £3-4k to get it close to 400bhp, which by the way is still on standard engine internals and gearbox. You then need to think, how long is this going to last, and what do I modify next. Personally, and this is only my opinion, the base model for cheap and reliable power needs to be an STI. gearbox - good for over 600bhp, Brembo's with the right disc pad combo - good doing power, engine - already partially forged - good for up to 450 if mapped right etc...
It's a hard choice, but £10k generally gets a very good saloon these days with the power you are looking for.
So not too **** on your chips - if funds are right and you enjoy the walk of modifying a car knowing you'll not get your money back that you put into it, then carry on with your WRX. It'll still make you grin from ear to ear when you get it just right...

You don't have 330bhp if you still have a TD04 turbo. Simply not possible. Even a TD04 hybrid would need to be running "grenade" levels of boost.
300bhp would be the absolute most but that would need a bigger fuel pump and injectors. With just induction and exhaust you're going to be hitting around 280bhp.
330bhp is a realistic figures with bigger pump & injectors plus a turbo from an STi such as VF35/TD05 and improved intercooling. More than that and you'd need an aftermarket turbo and supporting parts. That's when everything starts getting expensive.
But as said, if you want more than 330bhp, buying an STi as a base makes far more sense.
