My Turbos are ment to be finshed and back to me by next week (only been like 2 months)

I'm considering upgrading the exhaust manifold while the turbos are off.

I saw the Tomei kit on nengun for $1144 delivered Tomie Info, I thought it seemed pretty good. The kit comes with a heat Bandage, Clamps, and most importantly Stickers :D

But i'm also considering the UAS honed and heat treated stockers for $790 + delivery.

Is the tomie kit worth it, or is it just paying for a Jap brand? Or should I keep the stockers?

The reason I was wanting to upgrade is cause the exhaust housing on the turbos is ceramic coated (there the old 2530's from the Paul and Stacey's car), and I thought I might as well get heat treated manifolds to go with them.

Thanks

Id try the unique manifolds, as heat retention is the key to aiding gas velocity....and the thick walled cast manifolds do a superb job of doing that, do you know if they are ceramic coated as well?...good luck with the upgrade....those little turbo's sure were good for us...i hope they serve you well.

the UAS site says that they're HPC coated, is that ceramic?

Yep id go for them for sure, the coating is worth $300 a pair, the extrude honing is probably about the same. So to save yourself the trouble of doing it yourself....get em.

Looks as though they leave the lip into the turbine housing there. Wonder why? Cuts into the flow at least 4mm.

Tomeis look nice though. Investment cast tubing. Would be a real dilemma to decide.

The stock manifolds crack around the outlet if you remove much meat from there...that's probably why.

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
