Coated I bet, they rust out from the inside anyway. Try fabricating a bare steel system without a coating on the inside and see how long it lasts. You would need to factor in the coating costs to compare them properly. E85 will limit it's life even more.

I don't need other people to tell me anything btw, I remove so many rusty shitty mild systems and replace them with my custom stainless, the piles of old pipes are leaving stains on my concrete. Do you want some? You are welcome to them.

Your choice at the end of the day, I hate seeing rusty shit under my car. I guess if your ride is devaluing to nothing then a few hunge is not worth wasting on it.

ummm how often are you under your car! :woot:

Kirawee Mufflers stuck a 20" long oval on the back of my 25T , I can't remember the depth and width but it is really quiet . It's an off the shelf Redback from memory available in 3 and 3.5" straight through . The Nismo rear can that was removed is larger area wise and I wonder if it can be gutted and rebuilt to keep the really big for an R33 can volume .

The muffler is 7" diam. and 500 mm long. It might be a little squeezy in the length department. If so it will be reduced. The bigger the muffler is the quieter it will be without hp loss. It is fitted ith a 409 s.s. perforated tube. It is packed with a mixture of stranded fibre-glass and inox which gives it a higher temp. rating.It has a quieter, deeper sound. If the muffler was intended for circuit racing the fibre-glass would be discarded and replaced with gtb or inox. The perforated tube also has an expansion joint to stop metal fatigue when hot. The resonator is 4.5" diam. and 400 mm long. It has same perforated tube and packed with inox.

      Have you done the Ignition Sync Wizard in the AEM software?

      R32 GTS (RB20DE) Injectors Replacement

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      RB25DE NEO with Haltech ECU

      By MBS206 · Posted

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
