ok so generally speaking youve got an internally gated turbo,well they say that a divorced/split dump is better for the flow of gases,better flow equals better response and power,but i think the straight dump is cheaper,while your at it im assuming ur going to do ur front pipe(dump to cat) ?if youve got the money go for split,and do the front pipe at the same time,get an exhaust guy to fit it for you as there may be some welding required..much easier that way..

well instead of starting a new thread going to bump this one.

at the moment my car ebc @ 10psi, r34 smic, 3" cat back, pod.

i'm going to get it tuned soon and was wondering if it will be worth finishing my exhaust.

like how much power difference will it make after the tune having the dump/front and not having it?

and an upgrade of turbo in the future has not been ruled out

thanks

yes it's very worth it. more response, more midrange, more power throughout.

get a 3 inch dump/front pipe, and a highflowing cat. preferably a metallic cat.

i'm guessing you already have an aftermarket ecu or piggyback that you'll be getting tuned?

i spoke to an exhaust guy at his workshop about dump pipes, and he says avoid stainless steel because of the high heat temps the turbo can build up, and a high-flow cat to go with it so there is a more free flow. You will also need to buy a gasket for the turbo/dump from nissan or somewhere too.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?
