I have a r33 GTS-25T Auto with 10.5 psi, air filter and blitz DD bov, it has now come to the time where i need that bit more and i was thinking turbo back including dump pipe 3inch. iam new to this "modifications" scene so i come to ask for all you skyline drivers wisdom...Will there be a noticable change in performance? if so where at? top end? bottom end?i have also heard that i can run round 12psi with this mod.

ps. Anyone know any places where i can go that do a good job? or of any good prices?

ok exhausts are pretty straight forward as far as it all goes. Your main consideration should be noise and price.

Normally its one of the first things people do as it allows the later mods to really show through.

The bigger the exhaust the louder it tends to be (althought exceptions may occur).

I'm running an r33 s1 gtst and the first thing i did was get the zorst upgraded to 3 inch all the way from the turbo (inc dump pipe) and whack on a 3inch tip. It wont really effect how much boost you can run instead it effects how it responds to boost if that makes sense.

As for power, well the engine should feel less limited through the entire range.

Next question... aftermarket or custom??

I side with custom as to me a tube is a tube and where as mandral bends etc are good, after market mandral bends are the same as custom mandral bends if of good quality, so why spends a whole pile of extra cash. All your looking for is the shortest least restrictive way out for the exhaust.

My exhaust cost me 1300 from western mufflers in fairfield syd, there pretty good in my eyes. By bro in law uses them to build his drag cars exhausts aswell, they know what they're doing, with the added bonus that the owner talks like dr nick from the simpsons. Also in my eyes it has a nice note and isnt too loud

For the time being i'd worry less about upping boost and more about prepping the engine so that when you do up the boost the engines ready for it.

Next i'm gonna do the ecu then boost controller then fmic. I'll replace my BOV once boost gets high enough that i have to, otherwise its just cop bait and noise.

    • I also used Knox driveshafts when I the slip yoke T56 to the 3bolted TR6060 type. I believe I was one of his first jobs as it literally changed hands when I was there, started by the old owner and finished by the new. Everyone seemed pretty great about it. So wasn't shy/seemed pretty knowledgeable when dealing with weird custom people like me.
    • Just a reminder orange park was cool back in the day   and drifting the main circuit was even cooler   f**k I miss that car  
    • We used Knox Drive shafts years ago when we were doing gravel rally, good guy but I heard it had changed hands? He's got a lot of stuff and is miles cheaper than GJ and so on. He used to have a lathe setup with a MIG torch on the tool holder so he could get the uni welds just right, quite a clever guy. I just got a driveshaft done for my sequential installation and that was through Balancing Services Australia in Preston, they did the Gibson cars in the old days. New genuine CV's, billet yoke, new centre bearing and chome moly shaft was $2k.
    • Thanks for sharing that mate, I've got a couple of spares on the shelf but all the unis are tight....will give old mate a shout. BTW are you sure it wasn't just a $400 paint job? Any detail of what they replaced (cut/reweld?)
    • Yeah I saw that about the US Q50 recently, apparently it was shown to Inifiniti dealers (probably to help with their depression about the cars they can sell). Seemed like a really obvious step to me, the platforms are very similar in many ways. Even if there aren't many people who actually put the money up it should really help with image/reputation. What hasn't been clear anywhere if that is a V38 model of if they are just going to add the trans as an option in a new model year. What they did with the Z from 370z to "Z" is just weird so I'd be surprised if they released this as a V38. Great news for me to have an option; it is far from confirmed that I can get any decent track sessions through the auto so having a manual I can swap to is great.
