Got a screamer by accident, I wanted plumback. It will be getting fixed thank god it is too farken loud, just cop bait:)

Luckily, I have already opened it up next to coppers going the other way (also got a bit sideways) and they didnt turn around, but its only a matter of time.

The only problem with having a larger turbo with open wastegate is that you hardly ever hear the BOV anymore. That's what happened to me. When the turbo spooled up it was quite a loud high pitched whistle, then the wastegate would open and that's all you heard. The exhaust also became a lot louder on idle. I don't find these noises annoying, but what is annoying is having an external fuel pump. They are so noisey, and a constant buzzing which gets annoying after a short while. In summer it seems to work harder and get louder. Much better intank.

I actually like the fsshhh of my BOV. At one stage the car was making so many noises: Exhaust, external fuel pump, BOV, turbo whistle and open wastegate. Just like an orchestra :) But now that my car has had its stock turbo put back on, it's a lot quieter and I can hear the BOV - which is a nice change :D

What BOVs do people have? I have the BLITZ one and I think it sounds sweet. I was going to go for the HKS one but I thought it was a bit too high pitched for me. Does anyone have the GReddy/TRUST one? How's that?

Because the manifold keep cracking :) I bought that second hand and if you've ever seen the walls of the manifold (HKS, stainless steel) it is extremely thin. Only 1-2mm!! It kept on cracking due to the weight of the wastegate (50mm) which is very heavy for such a thin manifold. So I would suggest anyone out there who is bolting an external wastegate to a manifold to make sure it can hold it. Maybe even get a mild steel manifold to save costs and make it thicker and more durable.

Also, I am hoping to sell the car soon and I want to keep the turbo and wastegate for my next car :D

Who says no-one knows what they sound like?!?!?

I bar-up chronically when i hear one :D

First decent one I heard was trying to race Merli in his White gts-t (big mistake) and i had my window down and nearly went deaf!

Then in Brett's weeeeeeeeeeeeeeeee-mobile i couldn't decide whether i liked the wastegate opening or the rubber frying sounds better?!?!?

I can pick em a mile off now... BOV?!?!? Girl-toy.... :)

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
