Bellato Donating Members 2,713 Member For: 14y 4m 3d Posted 02/02/13 08:01 AM Share Posted 02/02/13 08:01 AM I know this has kind of been done before but I need to start getting mods organised so I can start saving and buy what comes up cheap when I see it. Basically I think I'm set on all the mods I want except the exhaust is the only thing confusing me.Supporting mods will be: Rapid v2 kit (includes turbo side intake)KPM 1000cc injectorsWalbro in tank fuel pumpPlugs etc to match tuneSo looking for 300rwkw give or take but more worried about the driveability of the car as its a daily. I was thinking of going just the cat as its cheap and I've seen time and time again people hit 300 on about 14psi with cat and mods like above. But what sort of gain is there to be had with a 4" dump aswell? Is it worth it if I don't earn a real lot? (probably take me an extra 2 months just to save for the dump)I realise theres about 10rwkw to be had with the dump but more concerned with how the power is through the mid range making it feel like more.Has anyone done the basics to get to 300 and then just added the dump and if so how much difference did you notice and would you recommend it?

Just a cat is fine, right upto mid high 300s. Link to comment Share on other sites More sharing options...

What this does to the whole tune I am unsure but I dont think its worth the dollars unless going a bigger turbo later on! Link to comment Share on other sites More sharing options...

Just a cat is fine, right upto mid high 300s.Is it possible to do flapper mod without cat? to hit mid 300s you need to go over 12lb of boost for sure.I'm thinking pretty similar mods, prob surge and eflex, maybe pw stepped intercooler. I didn't know the route to 300++ could be done without dump (on stock turbo). Link to comment Share on other sites More sharing options...

But this is what Pete P did. CatInjectorsFuel pumpE85Cooler pipes. Made 330 an ran 11.3@123. G6e open diff too. That was first time out and only on 18psi iirc. But rather than better it he's banged an f6 turbo and nizzy cooler on and now he's making 430. Link to comment Share on other sites More sharing options...

Bellato Donating Members 2,713 Member For: 14y 4m 3d Posted 02/02/13 09:21 AM Author Share Posted 02/02/13 09:21 AM Okay thanks guys!I was under the impression that the smaller FG turbo had a bigger flapper or something like that making it easier to control boost spike when putting a dump.I agree that 300 will be a huge jump from standard and even standard I love how hard it pulls! Might just stick with the cat then and once uni is finished and I have a job, full 4" exhaust and gtx Link to comment Share on other sites More sharing options...
