Thanks for the feedback lads

Might just be me but that doesn't look right to me i would have thought the wastegate would have been to the rear of the turbo. Also the cold side will need clocking more as you have to remember the angle of the engine, as it is now the outlet will be pointing at the bulk head.

Im probably wrong about the wastegate but sure some one else will be along to confirm

The clocking hasn't been done yet, I've just adjusted things roughly so that it is recognisable that it is a turbo. As for the wastegate location that is something specific to this turbo, it would have made sense on the engine it was originally intended for

Almost looks like you've got it mounted upside down tbh, or do xuds actually sit like that..? Turbo needs some clocking, should really be thinking about things like wastegate actuation, comp outlet position, etc long before you start cutting and welding stuff. Trimming the excess off that plate should help.

If the turbo was mounted the other way around the exhaust side would be where the compressor side is and the compressor side would be where the exhaust side is And it would be really low.

As for planning ahead well that is not really my strong point, I find it hard to visualise stuff that way. And would the excess on the adapter plate get in the way? I have already had to do a fair bit of hacksawing and would rather not have to if it is not necessary!

And as I have mentioned, I have not clocked it yet, I'll have to do that when it is on the engine! Should be one of the easy bits!

Really liking where your EGT probe is sitting now mate.

For the waste gate actuator id be looking to move it round so it sits above the CHRA or even further, you may find you need a new actuator and maybe use a slightly bent VNT actuator bracket to mount it in the right place.

As for testing it I used a bike pump as I've tested the gauge against a known good boost gauge and its spot on. Have a look at my project thread.

Thanks Dum-Dum. I believe that Dave mentioned something about the wastegate but he didn't elaborate, I'll see if I can get his attention.

Fake edit: Just realised I can get a bit of metal welded to the turbo to mani adapter plate to act as a bracket for the wastegate, so that's the problem of what the bracket will attach to sorted

As for the actuator, can I use any actuator? As I have an actuator on the scrap turbo that I bought by mistake, it is a lot smaller than the one on this turbo!

Fake edit 2:

Okay, found the Dave post:

I might have missed this in the thread previously, but what are you going to do about the actutor and clocking the compressor?, 'cos this is gonna be a major issue even for someone with a welder, a bracket will need to be made, and fitted so it doesnt foul, and where your actuator will then sit, is exactly where your turbo outlet for your intercooler is. You could possibly bend the actuator rod and have it behind the compressor which would work, and then get someone to just simply tack it in place on something steel, this would be the option I would go for.

Hi, Dave. I see what you mean now I really am the kind of person that has to "learn the hard way" so to speak. As I am now at the stage where this has become a problem, would you care to elaborate on what you mean? And bare in mind any bracket that I need can come off the adapter plate so there are plenty of options as to the location that it can start from.

Well I think that's it for now. I am worried about getting stuck at this stage TBH, it seems that there is no immediate solution unless Dave can come to the rescue

Hoping to get this fitted over the Christmas holidays, so running out of time to get it ready.
