I wouldn't be too scared at running a bit more camshaft than oem, not wild spec n/a cams, but on a nice 4 valve per cylinder head there are gains to be made. I went for some second hand kelford 264's in my old evo, and back to back testing with no other changes it picked up mid range spool, and peak power and earlier peak torque with a couple of psi less boost. No downside in my opinion other than a very slightly choppy idle. Interestingly it increased the pressure figures on the compression test by by nearly 10%. Not sure if this is normal? As @kpr eludes to, you could go for a staggered cam setup which is quite popular for instance a kelford 280 inlet and 272 exhaust is something that i have seen broadly work well across anything from a 2J to a 4G63T.

Borg s200 sxe, maybe in about 57mm.. Probably go bigger on the hot side a/r depending on engine spec https://turbocare.co.nz/products/s200sx-e-57mm-0-82-t3-single-scroll-s257sxe?srsltid=AfmBOortjwsUYOeVcbBUfkFl3SuRsY6Cv3SrqLcJJhosei5GUJsxDKIQ

One thing to consider is camshaft selection, it sounds like it going to be something aftermarket if you are talking about 9000 rpm. What large camshafts do not like (gas flow reversion) is backpressure. So when you go up in camshaft generally you will need to ensure the ar of the turbine housing, and also turbine wheel selection doesn't lead to too much backpressure. Many people think the a 'big' turbo automatically means you raise the boost threshold (not lag), but when paired with the right camshaft, and highish compression this is Lag is to do with wheel mass / momentum, so when you are at an rpm above boost threshold and you mash the loud pedal how soon will the wheel speed (lag behind) the throttle input. I like the deep compressor wheel design that bw have been doing for ages now. Where you get more compression ratio per turn of the wheel. / buy a borg warner, it doesn't need to be a shiny one. Even a John deere tractor one could work. Extra kudos if it's got green paint and the deer cast into it.

Maybe make it sound like a v6 honda* https://www.facebook.com/newzealandrallychampionship/videos/677994621865142/?mibextid=rS40aB7S9Ucbxw6v * mounted in the back of a jazz with added supercharger, and sequential gearbox.

Are the front camber plates correctly installed? It seems weird that they are right in on the slots and the camber is near zero. I was wondering if they were 180 degrees out, is the side to side centerline mean that you get a change in castor? / castor makes you faster. I added heaps to my racecar and it's great.

Great job, I'm now imagining some poor bastard having to replicate all of this work and more to my bugeye. Ha

Looks like it's trying to be an external combustion engine, but there is still some compression Can you humor us all by swapping back in one of the old glow plugs. Maybe the new one is dead?

Including the bmw aftermarket pipe designed by the wiggles i linked yeah?

Is the tension of the hold down screws jamming it up? Maybe try backing the screws off just a little and see if it fires into life.

Even a short length of additional tube or one size down in tip diameter can have a huge difference in sound in some cases. As @Roman suggests, I wonder what doing some funky slip on tip to go to two smaller diameter pipes might go for you.

I wonder what difference to the sound adding a bit of extra length to say one inlet to make the gas flow times out of sequence.and arbitrary length of let's say whatever a 180 deg bend could be.. I vaguely remember hearing about some new bmw thing my mate has that can have basic the sound of two 3 cylinder toyota gr yaris's, or a grunty 6 cylinder by ofsetting one set of pipes length by something like 150mm. It might have looked a little something like this. But as a prototype you just add one ugly bend to one bank and see what happens. As maybe yours is too perfectly even? Perhaps an option to try on the older version with the cool looking centre exit. https://store.activeautowerke.com/products/m2c-equal-length-mid-pipe-patent-pending-includes-active-f-brace

They look mint, sometimes the ends splay open when they shit the bed.

Did the glow plugs come out complete? Ie not missing my bits that fell off into the combustion chamber?

If you want to make it faster, maybe try running it on petrol instead of diesel. As some petrol cars are quite fast.

SO MUCH FLASH! how much meat have you got in the cam cover to create the strut brace clearance you need? it looks like its just on the drivers side, or is the coil cover also in the battle for real-estate?
