Im just about to get an exhaust put in from the turbo back... car is stock ATM

my question is .. will i need to change the dump pipe once i upgrade my turbo .. i will be upgrading to the GTRS Bolt on kit

cheers

Usually you do change the dump pipes when you have a new turbo installed.

You are upgrading to get more force induction right... Hence turbo upgrade, well you will need to get bigger dump pipes to allow better flow for the exhaust.

Then upgrade your, front pipes and install a high flow cat.

BTW I see you listen to Pantera... Yeeeha! Another Cowboy from Hell to join the Skyline enthusiasum. :D

while on the topic of dump pipes, GTR

i have some that are 2.5" and 1.5" wastegate pipe that vents back just befor the flange, got front pipes 2.5" to 3" decat and 3.5" back now

i am looking at cutting the wastegate pipe about halfway and gringind and blocking the return then bending up a 2" pipe (screamer pipe) and running them both to the bottem bend of the front pipe straight on the ground, its this worth it? what are some ppls opinions some told me to just run it down and vent it in just before the cat. im not worried about the noise factor.

    • Yeh... literally every time i jump on a forum, see an instagram post or see an engine bay at a car show, i get an idea and add it to my 'to do' list. So what started off as, hey can u just make a couple of intake hard pipes because my dumbass bought the wrong apexi kit, blew out into a 2 week job including braided brake lines & custom bash kit for the front lip haha.  Getting Luke from A4E engineering to make a full custom exhaust with a controllable aes dump valve so i can actually switch between quiet and loud, because right now its just loud all day every day. Then after that go and get the tune redone flex e85 & 98 as i get bugger all milage from e85, makes going for longer drivers difficult
    • Car looks clean as. You ended up getting quite a bit done 😂  So what's the plan for the exhaust? 
    • The only Neo rods that were any different to any other RB25 rods were the DET ones, and they were the same as RB26. Here is a Neo DET rod. O5U part number visible. Here is a post in a thread here on SAU with evidence from someone who has done this before. There are photos in the thread of normal RB25 rods.  
    • Sure, but why assume that will be the case forever? And why assume you'll be able to do an oil change to swap back to a stock drain bolt before that happens? And does it even matter when I change the oil at fairly short intervals? Life can be funny sometimes and unexpected things can happen. Like breaking a collarbone so you can't do any work on your car for a few months but the oil change is due so you have to take it to somewhere and hope they don't do something stupid like stacking the new drain plug washer on top of the old one.
    • Do u know how to identify the rods are rb25 or neo ones? Can u look into the pics and tell me is they de or de neo ones. Its confusing becoz my motor has de neo head but block is 25de 75t, so really confusing me about rods, crank.
