I know there is nothing like actually seeing the thing in real life, but just want to know if anyone has any ideas.

Just replaced the turbo with a GCG last night, results good, but just after any major job you listen for noises. One noise i get is at about 1100 RPM, my injector area (pointed to by a mate) makes a rattling noise like as if a nut was in a metal plate sitting on my engine block.

This noise does not occur in nuetral, only when under load (was against the torque converter)

I cant find anything where it actually is a nut or bolt, but I will have another look. Apart from that, any ideas guys? I am only scared driving with it will be worse then not in the end.

Also, the noise is not constant. Its only happening when cruising or accelerating, not when on boost (also higher RPM)

The noise isnt so much a rattle, but it sounds pretty much exactly like a VN commo acclerating away, that kinda rattle/ticking noise (minus the exhaust noise naturally)

Its quite loud also, loud enough ive never heard it before. To be honest, it sounds like a noise I heard when the car was stock but just a LOT louder and worrying. The other noise I heard on idle with humble (on his car too) but this is something different. I can hear it inside the cabin with the windows up quite easily.

I beleive i have solved my own issue

A note to everyone as well

I have a split dump pipe, it has a splitter in the middle. When the car is just slightly reving so the wastegate is only slightly open, it rattles against the splitter.

I will get it cut off and a new splitter rewelded on bent a bit furthur away from the wastegate

Well solved Alex.

I might have to drop my Stag off to you for a full service & tune next, with a full 200-point safety check!!

Joke LOL, Brendan ;)

i have a GCG. Quite laggy / Stock boost.

Umm, yeah, thatd be right

They are most efficient above 1Bar (arnt they???)

But Im sure once the ECU is done and dyno'd then you'd find it to be Perrrfect, with what, 200awkw?

uhh, 7, 8 around that area. My Jaycar EBC is on 100% duty in the high RPM.

Ill tell you what though, even though power doesnt come on really until 4000rpm ish, when it hits....mate for stock boost... it hits. For me to get from 4000-7000rpm in first no shit takes 1.5-2 seconds MAXimum.

Ill grab my mates dad mega Gtech (not the eBay one, the laptop version one) and let everyone know what I am gteched at compared to my calder run of 14.7

    • Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points? 
    • I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.  
    • Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?
    • So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
