ECU tuning is only going to net you a little bit of power. Like Count said, you want a minimum 3' exhaust. The stock fuel setup is pretty good for decent horsepower, but if you are going to get nutty with the car, that should be upgraded soon.Count Zero wrote:First and foremost.....exhaust. Minimum of a mandrell-bent 3" system, catless if you can get away with it (emissions laws)Then free-flowing intakes.
Then......
Boost controller, set it to 1.0 or 1.1 BAR.
Then get a fuel/timing management thing, like a AEM EMS to tune it.
You didn't specify whether you have an RB20DET or an RB26DETT so I have to generalize. If you are running the stock ceramic turbo(s) don't do more than .9 unless you have another 1(2) you need a reason to put on.Count Zero wrote:Boost controller, set it to 1.0 or 1.1 BAR.
does it have to be a mandrell-bent system, i mean if so ill get it but i didnt know if its te best thing for it or.. if you were refering. i only ask because the mandrel bent is hard to find arond here.. so i want to know if soCount Zero wrote:First and foremost.....exhaust.

yea i know how big should i go.. i dont want to look like a bow bow toothemadscientist wrote:All aftermarket exhuast is mandrel bent. I think he specified the mandrel bent in case you had it custom made. Bubbas muffler shop uses the wrinkled up Pepboys stuff.
I mentioned the Mandrel-bent just to make sure you don't get something that's crimp-bent or wrinkle-bent.....those make every bend a choke-point that bogs down the exhaust flow.greddy2smoke wrote:yea i know how big should i go.. i dont want to look like a bow bow too
im going without cat, tommorrow, should i keep the silencer or no, if has one, i didnt remeber to look, and its night now.. and cold. but what should it be a stock for boost, my gauge isnt working.. how big should the muffler be? or doesnt matter?themadscientist wrote:As big as you can fit, 3" will get the job done.
headers? is your RB26DETT without the "TT"? or do you have exhaust manifolds with turbos? headers are what you get for NA V8's.greddy2smoke wrote:got a r32 stock.. and i want to achieve more horse, now..whats the best way you guys got more hp cheaper.. i know its headers, exhaust, intake..ect.. but. i was readying on here about tuning the ecu's?are they really that effectiv for power, i mean i dont know, but i want to know which should i do first? i dont know. i want to do it professionally and nicely well thanks for the info
Ok. Let's clarify. Headers are aftermarket exhaust pipes for NA application exhaust manifolds. "Turbo manifolds" are for tubocharged vehicles.C33LaurelRacer wrote: Aren't RB26's two piece exaust manifolds? If so, in theory, that would be "headers"...lol. No worries though.
C33LaurelRacer wrote:I have seen several GT-R's running around here that use 3.5"-4" catbacks, and they sound mean as hell, but I think the 3" turbo back (to include front pipes as well) would be plenty for right now. The big dogs use the uber large diameter for the extremely high speed runs down the wangan.
If you are buying from a dealer, look into companies like HKS, Greddy, Blitz, JIC, Jazmo. Those are the bigger names here, but their quality is damned good. Just be prepared to pay.
OK. Then let's just call them "aftermarket tubes getting the exhaust gasses out quicker."Okinawa_BNR34 wrote:
