I want it to purr like it does with standard exhaust, but gain some power.

will run them next to each other and ad a crossover later if it sounds crap.

Have a theory that the early turbo will create back pressure to the late turbo if the pipes are joined. Could be wrong, dont know too much about cars but would like to try it.

sb..

appart from the extra weight and difficulty in getting decent size pipe diameters to fit it is going to allow more head room for flow potentially.

As for sound? who cares. The sound of power is an easy one to get used to. It will sound different to a single if it makes more power then it sounds better in my opinion. For those hung up on sound why not get rid of the turbo and go NA with a set of extractors (thats where your logic will end up).

It will sound crap. There is no "if"

early turbo and late turbo? a RB26 isnt a sequentially turbo'd motor

Thanks for that, sounds like you saved me some greif, I allways thought they were identical turbos but someone recently told me they weren't. I thought they might be wrong cos i had never read anything like that.

cheers for the help!!

they are identical turbos mate, not sequentialy staged. Providing of course you own a GTR i suggest you run outside and have a look under the bonnet. or drive it. then tell us if you think it's sequential turbo or not.

oh yes! its a GTR, took it for a couple of hot laps around the block just to make sure, he he.

No i dont think they are sequential.

wish you could just throw one on to see what it sounds like.

I will have a twin exhaust on my RB26 in approx 6-8 weeks should chrissy not get too expensive

And this is from a person who has done this just a little more than once...

cross-over to balance it or it does sound... yuk!

originally you said a twin system would sound crap.now you are getting one but it will only sound good with a balance pipe.I guess then type/placement/diameter/brand of mufflers/resonators/cats etc is irrelevant : "they will all all sound crap"

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
