First problem i can see with that is the 90 degree silicone joiner from the turbo outlet...the radiating heat of the s/s manifold will weaken the back part of the joiner and it will eventually blow through :laugh:

Two race meets our one lasted, then i had to tig an ally 90 pipe on to replace it. Not having a go at your setup...it looks very nice. Just giving some warning. Being a street car, it might hold up alot longer, but my money is still on that it will go sometime. Maybe wrapping the manifold? Could help.

Very nice though :wub:

I would have to agree.

Also what exhaust manifold are you using?

Same thing happened to mine on front straight at PI.

Very hard to figure out when it first happens coz you can see the crack until you start pulling things off

I would also agree, based on personal expirience, i went through 2 90 degree bends :P

The heat from the exhaust housing just burned a hole through the silicone in a matter of weeks.

And fullboost @ 4500 :teehee:

I bet fullboost = 5psi

IT WAS 12 PSI

You will need to replace that 90 degre bend as i have had the same issues...

I have also found that the chinese manifold ok to around the 280-300rwkw area but anything more than that and they will crack and bend. The stainless is just not strong enough to hold anymore heat...

Also you want to insulate your down pipe from the back of the turbo with heat tape to aviod affecting you air conditioning pipe work...

Other than that, she looks great...

The dump pipe is thermo wrapped....i tried to tell him to ceramic coat the manifold but he likes the bling factor. The manifold is no cheap "chinese knock-off" either its a well constructed local item with the runners extending right through the flange plate to the ports...it could have had a support tab welded to each runner for added strength though.

EDIT: many thanks to GCG who provided us with the "bolt on" water and oil feeds...."bolt on" yeah right!

HAHAHAHA

GCG supplied me some 'bolt on' water and oil feeds....

The oil return is not really designed with a high mount in mind. As it touchs the manifold so im gonna have to run the turbo on a slight angle to make it all work with out burning anything... :whistling:

Arhhh i could not see the rear... I just assumed it was not done...

PS. I am using a chinese manifold and she is working quite well but have been told not to push it too far...

Im only after 270 or 280rwkw anyways...

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