- RB25Neo turbo

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.

    • Yeah, you are right. It seems easier and more reasonable to boost the engine. And as you said the blocks are very similar but the cylinder bores are different.
    • Sound logic, but in actuality way more illegal than just having the wrong pipe. Normally, doing something like that would be forgery. Meaning you may have certain documentation for vehicle parts, but the actual parts are different ones and you just assign them the numbers and badging from the documents. But nevermind that. Nonetheless, I AM curious if this pipe was ever made by any official manufacturer this way, because I honestly am not familiar with this pipe layout and shape. As I will be putting on the HKS Silent Hi Power once my exhaust gaskets arrive, as long as it sounds right I will just roll with this front pipe. I can always order the actual Mines part if I run into legal issues. It would be an unnecessary expense as there is lots of other problems I have on this car as of now.
    • So, weld a plate with the Mines logo laser cut into it, onto it. Instant Mines pipes, whether they were or weren't originally.
    • I don't know if the blocks are "the same". They will be very very similar. Obviously, either the bore or the stroke is going to be bigger on the 20. If the bore is bigger, then the 18 head is unlikely to fit properly. If the bore is the same, then you can almost certainly fit the CA18 head, but there migth be a few fun things you have to do to make water galleries (or other things) line up properly. Or... it could just be real easy. Is it worth the effort? Almost certainly not. You can make nearly as much power on a 2 valv ehead as you can on a 4 valve. There's not any "magic" in a 4 valve head.
    • Yes, me too!!!!  I need to find a something that has all the abbreviations for what these cars have LOL
