No problems, except for a bit of drive line noise if you are in say 2nd or 4th gear taking off at low revs etc. The chromemolly tube transmitts some of the noise from the gearbox. Gbox is second hand anyway.

In rwd it does light up wheels alot faster. Little difference in acceleration probably due to lighter flywheel and tripple plate assy.

Be warned, your two piece gets chopped up for it's ends so you can't swap back unless you but another two piece like I did, just in case....

Well guys, just had a new custom 2-piece fitted and guess what - no more high speed vibration problems. Mine was put down to an alignment issue between the gearbox and diff - so if your fitting an RB25 box to an R32 GTST be careful when deciding to go the one-piece option.

Well i rang a place today to arrange my new tailshaft to suit the R25 bos on my R32...and was told not to bother with a 1 piese unit :laugh:

I said its what i want though as im told they are lighter and better, and, well just better :)

His reply was they woudl be too long for a 1 pce, and a 2 pce woudl be far superior. Considering this guy does race cars, inclusing a friends Gibson Grp A car recently...im taking whatever advice he gives me :rofl:

So 2 pce fo rme, but im curious to hear that ppl running 1 pce find it more responsive.

I found absolutely no difference in response with the one-piece (metal) over a 2-piece (metal).

I think you received some good advice from this dude :(

if there was any advantages id say that there is no centre bearings (less maintenance) and its damn lighter. I can pickup my 1 piece with 1 hand.

I put mine in as i fitted the rb25 box, and havent had any problems. It was probably easier to make a single shaft with the ends i needed than mod a 2 piece.

    • 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.
